Of the aircraft used by the major powers during the Second World War least has been written of those produced by Italy's aircraft industry. Indeed, so little detailed information has been published on the aircraft employed by, or under development for, the Regia Aeronautica, that there is a serious gap in the reference generally available concerning the military aircraft of World War Il. This account fills that gap. It covers aircraft used in service (as well as those under development) up to the fall of the Fascist Government in July 1943, and subsequently in Northern Italy while under German occupation. Many of the types described and illustrated appear for the first time anywhere.
The quality of Italian combat aircraft was frequently derided during
the war years, and it was generally supposed that the equipment of Regia
Aeronautica squadrons was considerably below world standards. In part
this was true, for while Italy's aircraft designers were undoubtedly
capable of much first class creative work, her aircraft industry never
acquired the ability to achieve quantity production without allowing the
basic design to become obsolescent.
Immediately before the war Italy was one of the leading exponents of
the high-performance attack bomber, some of which set up remarkable
"prestige" records, producing several types which were among the fastest
in their class at the time of their appearance. But, paradoxically, the
Italians were strangely sentimental with regard to fighter biplanes,
devoting a sizeable proportion of their production capacity to such
types long after they had been discarded by all other major air powers.
Although the Italian aircraft industry was loath to discard the biplane
for the interception role, it should not be thought that such machines
were developed to the exclusion of the fighter monoplane. On the
contrary, six distinct types of fighter monoplane made their debut in
1937-39, but their designers were forced to contend with one major
handicap, the lack of a high-powered, low-drag, liquid-cooled engine.
Reliance on comparatively low-powered, bulky, drag-producing, air-cooled
radials rendered adequate armour protection and effective offensive
armament secondary considerations where a reasonable performance was to
Thus, it was with obsolescent fighter biplanes and under-powered
fighter monoplanes that Italy's Stormi Caccia (Fighter Squadrons)
entered the war. The later availability of the excellent Daimler-Benz
series of liquid-cooled engines gave Italian fighter aircraft the much-
needed "shot in the arm", but even then inadequate production capacity
did not allow for the disruption in the flow of replacement aircraft
that would have resulted had any attempt been made to introduce
completely new fighters. In consequence, existing air- frames were
adapted to take the new power plants and, surprisingly, several of these
Italo-Germanic combinations proved to be exceptional fighting machines.
This was fortunate for the Italians, for no single-engine, single-seat
fighter of exclusive Italian wartime design ever reached the squadrons
of the Regia Aeronautica.
A substantial proportion of Italian combat aircraft production was
devoted to twin-engined and tri-motor medium bombers, but of the 13,253
military aircraft of all types produced in the years 1939--43 inclusive,
only 163 were four-engined heavy bombers, and after several relatively
abortive attempts at strategic bombing, the Regia Aeronautica confined
its bombing forces to tactical duties. Several light and medium bombers,
obviously influenced by German trends, were entering service or under
development at the time or the armistice.
The Italian aircraft industry never succeeded in developing mass
production techniques comparable to those developed by the other major
powers. In consequence, the total number of combat aircraft produced by
Italy was uninspiring. Whereas in 1940, the year of Italy's entry into
the war, production was nearly double that of the preceding year (3,257
aircraft as compared to 1,750 aircraft), no commensurate increase was
attained in 1941, when 3,503 aircraft were delivered. Subsequently
output fell off, dropping to 2,813 aircraft in 1942 and only 1,930
aircraft in 1943. Such production figures were inadequate to replace the
Regia Aeronautica's losses, let alone increase its first-line strength
and its numbers-which had comprised 1,458 bombers and transports and
1,160 fighters when Italy entered the war-gradually declined.
AERONAUTICA UMBRA: The Aeronautica Umbra S.A. of Foligno was
established in 1935, and was primarily concerned throughout the war
years with sub-contract work for other aircraft manufacturers. However,
Aeronautica Umbra's design office, which was responsible for the
unsuccessful T.18 single-seat fighter of 1938, designed by Dr. Ing. F.
Trojani, did undertake some original work, and a heavy fighter of
advanced and unorthodox design, the M.B.902 designed by Ing. Bellomo,
was actually built, although flight testing had not commenced when the
prototype was destroyed.
The construction of the M.B.902 was begun in 1942, and this single-seat
fighter was unusual in being powered by a pair or 1,250 h.p.
Daimler-Benz DB 605 liquid-cooled engines buried in the fuselage and
driving twin contra-props mounted outboard on the wings via extension
shafts. Featuring a retractable nose wheel undercarriage and carrying an
armament of four 20-mm. and two 12.7-mm. guns, the M.B.902 had an
estimated maximum speed of 429 m.p.h., and a maximum range of 1,056
AMBROSINI: The Ambrosini industrial group took over the Societa
Aeronautica Italiana in 1934, and in the immediate pre-war years its
Passignano plant was responsible for a successful series of light cabin
monoplanes. However, in 1939, the chief designer, Sergio Stefanutti,
developed an unorthodox tail-first, single-seat fighter, the S.S.4. This
canard fighter was powered by a liquid-cooled engine mounted aft of the
pilot's cockpit and driving a three-blade pusher airscrew. A
retractable nose wheel undercarriage was fitted and vertical surfaces
were mounted on the wing at approximately mid-span. An armament of two
20-mm. cannon was mounted in the nose and flight trials started late in
1940, but the characteristics of the S.S.4 were generally unsatisfactory
and the machine crashed at Guidonia in 1941.
The series of light monoplanes had culminated in the S.A.I.7 which, of
exceptionally clean design and powered by a 280-h.p. Hirsh H.M.508D
air-cooled engine, gained the 100-km. closed circuit record for F.A.I.
Category I aircraft with a speed of 244 m.p.h. in 1939. The S.A.I.7
possessed excellent flight characteristics. Stefanutti had designed the
aircraft with the alternative role of fighter trainer in mind, and a
fully militarized trainer prototype flew in 1941.
The original prototype
featured a long, faired windscreen which extended to the front of the
engine cowling to reduce drag, but the military trainer had an orthodox
cockpit canopy for the tandem-seated pupil and instructor, and the
German Hirsh was replaced by a 280-h.p. Isotta-Fraschini Beta R.C.I0.
Despite highly enthusiastic flight test reports, the need for increased
production of combat aircraft necessitated the shelving of the S.A.I.7
trainer, but the aerodynamic qualities of the basic design were such
that Stefanutti contemplated its adaptation as a lightweight interceptor
fighter. The initial single-seat model, the S.A.I.107, was built for
research purposes and, powered by a 540-h.p. Isotta-Fraschini Gamma, was
flown early in 1942. The S.A.I.107 was externally similar to the
S.A.I.207, which was built to full fighter requirements and carried an
armament of two 20-mm. cannon and two 12.7-mm. machine guns. In dives
the S.A.I.207 fighter attained an indicated air speed of 466 m.p.h. at
10,000 ft. (representing a true air speed of 596 m.p.h., or Mach 0.86),
and maximum level speed was 357 m.p.h., which was attained on the 750
h.p. provided by an Isotta-Fraschini Delta R.C.40 engine.
Encouraged by the remarkable performance of the S.A.I.207, Sergio
Stefanutti developed the more ambitious S.A.I.403 Dardo, which featured
increased wing area and redesigned tail surfaces. Carrying a similar
armament to that of its predecessor, the Dardo was powered by a 750-h.p.
Delta R.C.21/60 engine which provided a maximum speed ~ 403 m.p.h.
Large-scale production of the Dardo was planned, but the armistice
precluded further development.
Other wartime activities of the S.A.I.-Ambrosini concern were the
construction of the AL-12P troop- and cargo-carrying glider designed by
Aeronautica Lombarda S.A., and the development of the Ambrosini AR
"flying bomb". Conceived by General Ferdinando Raffaelli as an
anti-shipping weapon, the flying bomb was powered by a 1,000-h.p. Fiat
A.80 radial engine and was to have been flown off the ground by a pilot
who would then bail out, the bomb being directed to its destination by
remote radio-control. Flight tests began on 13th June 1943, and four
further examples were built at the Venegono plant.
Flight trials were
successful and a speed of 225-230 m.p.h. was expected, but the bomb was
too late to see operational service.
BREDA: The Societa Italiana Ernesto Breda was one of the largest
members of Italy’s wartime aircraft industry, having plants at Sesto S.
Giovanni (Milan), Torre Gaia (Rome), Apaulia and Brescia. From the early
'thirties this company was preoccupied with the development of ground
attack aircraft, and two types were in production when Italy entered the
war, the Breda Ba 88 and the more elderly Ba 65.
The Breda Ba 88 Lince appeared in 1937, and in December of that year
the prototype established several international records (with a load of
2,205 lb. flying 62 miles (100 km.) at 344.5 m.p.h., and 621 miles
(1,000 km.) at 326.3 m.p.h.). Initially the prototype was flown with a
single fin and rudder assembly, but poor stability necessitated the
adoption of a rather cumbersome twin fin and rudder arrangement which
marred the Ba 88s otherwise good aerodynamic form. The prototype was
powered by two 900-h.p. Isotta-Fraschini K.14 radials and was one of the
fastest aircraft in its class at the time of its appearance.
Production orders far the Ba 88 were placed far the Regia Aeronautica
and assembly lines were established by both Breda and 1.M.A.M.
(Meridionali) with deliveries commencing late in 1938. The production
version featured considerable redesign and was powered by two 1,000h.p.
Piaggio P.XI R.C.40 radials which provided a maximum speed of 304 m.p.h.
The first unit to receive the Ba 88 was the 7th Gruppo, which arrived
in North Africa in September 1940.
However, relatively poor performance
and inadequate defensive armament resulted in the Ba 88 being taken out
of production after only 105 aircraft had been built. In 1941 the Agusta
concern substituted two 840-h.p. Fiat A.74 R.C.38 radials for the
Piaggios, increased wing span and fuselage length, and began the
construction of a small series under the designation Ba 88M. Only about
three aircraft of this type were completed.
The Ba 65 was a single-engined, low-wing monoplane which was already
obsolescent when Italy entered the war, although it was employed quite
extensively during the North African campaign. The Ba 65 was produced
with both the 1,030-h.p. Fiat A.80 R.C.41 and the 900-h.p.
Isotta-Fraschini K.14 engines (although, far operational service, all
A.80-powered Ba 65s were re-engined with the K.14), and a few Ba 65bis
were produced with a dorsal turret containing a single 12.7-mm. machine
gun. The Ba 75 was an experimental prototype produced in 1939 far both
the reconnaissance and ground attack roles. Bearing a marked family
resemblance to the Ba 65, the Ba 75 was a shoulder-wing monoplane with a
stalky, fixed and liberally strutted undercarriage, powered by the
900-h.p. Isotta-Fraschini K.14 radial.
Another Breda design that progressed no further than the prototype
stage was the Ba 201, which designation was, during the war years,
erroneously applied to a supposed Italian-built version of the Ju 87B.
In fact, although undoubtedly influenced by Junkers trends, the Ba 201
was an entirely original design. Powered by a 1,050-h.p. DB 601 engine
and featuring an inverted gull wing and retractable undercarriage, the
Ba 201 was tested at Guidonia in 1940-41.
Filippo Zappata, responsible far the C.R.D.A. Cant series of bombers,
joined the Breda design staff in 1941, and was subsequently responsible
far several interesting projects, few of which were actually built. His
first design under Breda auspices was the Bz 301 long-range, all-metal
medium bomber derived from the Cant Z.1018 but not built. The Bz 302 was
a projected twin-engined heavy fighter of all-metal construction
abandoned in favour of the Bz 303 night fighter. The Bz 303 was a sleek
two-seat, low-wing monoplane of mixed construction with twin fins and
rudders. Power was provided by two 1,450-h.p. Piaggio P.XV R.C.60j2V
radials, and the exceptionally heavy armament of eight 20-mm. Mauser
cannon (four firing forwards and four firing to the rear) and a 12.7-mm.
machine gun in a dorsal position. Maximum speed was 360 m.p.h., and
range was 963 miles. The sole prototype was destroyed by the Germans.
Other Zappata projects included the Bz 304 twin-engined attack bomber,
the Bz 305 four-engined troop and cargo transport, the Bz 306
four-engined long-range bomber, and the Bz 401 light
reconnaissance-bomber seaplane. No prototypes of these aircraft were
CANT: The Cantieri Riuniti Dell'Adriatico stemmed from the famous naval
construction company of Cantiere Monfalcone when the latter entered the
aircraft industry in 1923. Initially the C.R.D.A. concentrated solely
on the design and construction of sea-going aircraft, but in the mid
'thirties the company produced two land- based medium bombers to the
designs of its chief designer, Filippo Zappata. These were the
three-engined Z.1007 and the twin- engined Z.1011, both powered by
840-h.p.Isotta-Fraschini Asso Xl R.C.15 engines. Five prototypes of the
Z.1011 were built, but the bomber was under-powered and inadequate
performance led to the abandonment of further development in favor of
Quantity production of the Z.1007 was ordered in 1939, and in addition
to the C.R.D.A.'s Monfalcone plant, various other manufacturers, such as
Piaggio and I.M.A.M. (Meridionali), established production lines. The
production model, the Z.1007bis Alcione, differed from the prototype in
having three 1,000h.p. Piaggio P.XIbis R.C.40 radials, and was unique in
being produced with both single and twin fin and rudder assemblies. The
former has hitherto been incorrectly referred to as both the Z.1007ter
and Z.1008. Of wooden construction, the Z.1007bis Alcione was a very
efficient aeroplane, although inadequately armed, and was built In large
numbers far the Regia Aeronautica, serving on most fronts on which this
force was engaged. The Z.1007ter was externally identical to the bis,
differing only in having 1,100-h.p. Piaggio P.XIX radials, and the
Z.1015 was a further version with 1,500-h.p. Piaggio P.XII R.C.35
radials, both produced in small quantities.
Concurrently with development of the production models of the Alcione,
Zappata was engaged on the development of the twin- engined Z.1018, the
first of several prototypes of which flew in 1939. The Z.1018 broke away
from previous C.R.D.A. practice in featuring metal construction,
although one of two Piaggio P.VII- powered prototypes tested an
alternative wooden fuselage. Several types of engines were installed in
the prototypes, one having Piaggio p .XV radials, another having Alfa
Romeo 135 R.C.32 radials, and yet another having Daimler-Benz DB 605
engines. Some prototypes had twin fin and rudder assemblies, but a
single unit was adopted far the production model which, powered by
1,400-h.p. Atfa Romeo 135 R.C.32 radials, began to appear in service in
1943 but was too late to participate extensively in the air war prior to
Another major type designed and produced by the C.R.D.A. was the Z.506B
Airone tri-motor, twin-float reconnaissance-bomber seaplane which was
developed in 1936 as a military version of the Z.506 commercial
floatplane (the Z.509 was a further commercial development differing
from the Z.506 in having 1000-h.p. radials), and the Monfalcone factory
had produced ninety-five Z.506B float- planes by the time Italy entered
the war. Production was subsequently undertaken by Piaggio. The Z.506B
was employed primarily far maritime reconnaissance, bombing and torpedo
attacks on shipping around Italy's coasts.
The Z.506S was an ambulance
and air-sea rescue version built by Piaggio. The Airone largely replaced
the earlier Z.501 single-engined high-wing flying- boat, although some
of these obsolescent machines were operated throughout the war. The
Z.508 was a tri-motor flying-boat derived from the Z.501 (three 840-h.p.
Isotta-Fraschini Asso XI R.C.40), but only a small production batch was
During the war years the C.R.D.A. also completed two prototypes of the
Z.511 commercial transport floatplane designed by Zappata before the war
and intended far use on Alitalia's South Atlantic route. Construction
of the Z.511 commenced in 1941 and the first prototype flew on 8th
September 1943. The first prototype was destroyed when it struck a mine,
and the second, commandeered by the Luftwaffe, was destroyed in
Germany. The Z.511 was powered by four 1,500-h.p. Piaggio P.XII R.C.35
radials and had a loaded weight of 74,957 lb. The Z.515 WIIS a light
reconnaissance floatplane powered by two Isotta-Fraschini Delta engines
and built as a prototype only.
CAPRONI: The Societa Italiana Caproni, founded by Count Gianni Caproni,
had its beginnings as far back as 1908, and between the two world wars
became the largest group of companies in the Italian aircraft industry.
The most prolific company in the group was the Compagnia Aeronautica
Bergamasca, which began aircraft design in 1927, joining the Caproni
group in the 'thirties. The chief designer was Cesare Pallavicino,
formerly chief designer to Ernesto Breda, and initially the original
designs produced by Bergamasca were given Caproni-Bergamaschi
designations, but later "Bergamaschi" was dropped and aircraft emanating
from the Bergamo works could only be identified by their type numbers,
which were in the 300 series.
The Ca 309 Ghibli light colonial monoplane powered by two 185-h.p. Alfa
115 engines was the first of a series of light twin-engined aircraft
produced for export and for the Regia Aeronautica in considerable
numbers. The Ghibli was produced before the war and was used for police
duties by the Aviazione Presidio Coloniale and the Aviozione Sahariana
as a light reconnaissance-bomber and transport (carrying two crew
members and six passengers).
Several production series were produced,
the final versions of the Ghibli to Ibe produced in quantity being the
Series V and VI, the latter having a forward-firing 20-mm. cannon
mounted in the nose. A progressive development of the Ghibli was the Ca
310 Libeccio, which differed from its predecessor main1y in having the
spotted fixed under-carriage replaced by rearward-retracting main
members, and two 430-h.p. Piaggio P.VII C.16 radial engines. The
Libeccio was produced primarily for export and was supplied to the
Croatian Air Force.
The Ca 311 differed from its predecessor in having the "stepped"
windscreen replaced by a more extensively glazed Blenheim I-style dose
section (although the second production series, the Ca 311M (Modificato)
reverted to a stepped canopy rather like that later adopted for the Ca
314), and the Ca 312 was a version with 630-h.p. Piaggio P.XVI R.C.35
radials. The Ca 312M possessed a similar nose to that of the Ca 311, the
Ca 312bis was a twin-float seaplane variant, and the Ca 312-1S was an
experimental torpedo floatplane. The Ca 313 was a further development of
the Ca 311 with two 650-h.p. Isotta-Fraschini Delta R.C.35 engines
which was used in limited numbers on the Russian Front.
The Ca 313 could
carry a torpedo under the fuselage, and eighty aircraft of this type
were exported to Sweden in 1940. According to Swedish sources, the Ca
313 was generally unsatisfactory and had to be rebuilt and extensively
strengthened after delivery. Forty-one Swedish airmen lost their lives
in accidents involving the Ca 313 and, after the war. the Swedish
Government took legal action against the Caproni concern but, in the
meantime, the Societa Italiana Caproni had gone into liquidation. The Ca
314, an improved version of the Ca 313, was the last of the
Bergamaschi-designed light twin-engined reconnaissance bombers to be
produced in quantity. It was also used in small numbers by the Luftwaffe
and, surprisingly, was to have been built under license in Germany as
the Ca 315 (featuring a modified nose similar to that of the Ca 316).
The Ca 316 was a twin-float reconnaissance seaplane powered by two
450-h.p. Piaggio P.VII C.16 radials and intended for catapult launching
from warships of the Italian Navy. The Ca 316 was designed to replace
the obsolescent I.M.A.M. Ro 43 float biplane, but only prototypes had
flown before the armistice stopped further development. The Ca 325 was a
medium bomber powered by two 1,250-h.p. Isotta-Fraschini Zeta R.C.42
engines projected by the Bergamo design office in 1939, and the Ca 331
was a further light twin-engined bomber reconnaissance aircraft. Of
all-metal construction, the Ca 331 was projected in two versions, the Ca
331A reconnaissance bomber and the Ca 331B night fighter, prototypes of
both versions being built and flown. The latter version was to have
been built in large numbers and carried an armament of four 20-mm.
cannon and four 12.7-mm. machine guns. Power was provided by two
825-h.p. Isotta-Fraschini Delta 4 in-line engines and construction was
all metal. A projected escort-fighter variant was to have had an
armament of eight 12.7-mm. guns. The Ca 365, projected in 1942, was a
progressive development of the Ca 331 with increased wing span, higher
loaded weight and two 1,250-h.p. Isotta-Fraschini Zeta R.C.42 in-line
The Ca 350 was a projected a11-metal two-seat fighter powered by a
1,250-h.p. Isotta-Fraschini Zeta R.C.42 engine. This project, dating
from 1939, had an estimated maximum speed of 402 m.p.h., but.
construction was abandoned. The Ca 380 Corsaro was a twin- fuselage
two-seat fighter with the crew seated in tandem in a cockpit carried by
the port boom (a similar arrangement to that adopted for the S.M.92).
The Corsaro was powered by two 1,550-h.p. Daimler- Benz DB 603 engines
and carried an armament of eight 2O-mm. Mauser cannon and a bomb load
under the wing section between the two fuselages. A prototype of the
Corsaro was flight tested but eventually destroyed by the retreating
Other wartime Caproni products included the Ca 135bis medium bomber
powered by two 1,000h.p. Piaggio P.XI R.C.40 engines which was built in
small numbers for export to Hungary; the Ca 183bis, an unusual
high-altitude fighter which was under construction in 1943 and powered
by a DB 605 engine and a 700-h.p. Fiat A.3D engine, the latter buried in
the fuselage aft of the pilot’s cockpit driving a compressor for a
Campini ducted-fan type unit, and the Ca 225, a two-seat low-wing attack
bomber powered by two 800-h.p. Isotta-Fraschini Delta R.C.1750 engines.
Neither the Ca 183bis nor Ca 225 was tested.
CAPRONI-VIZZOLA: The Caproni-Vizzola S.A. of Vizzola Ticino (Varese)
was originally the Scuola Aviazioni Caproni, one of the oldest flying
schools in Italy, but in the mid 'thirties its activities were expanded
and a fully-equipped factory built. The plant was primarily engaged on
sub-contract work building the Breda Ba 65 attack aircraft, but in 1938
its first original designs, the F.4 and F.5 single-seat fighters
appeared, powered respectively by the 1,025-h.p. Isotta-Fraschini Asso
121 R.C.40 and the 840-h.p. Fiat A.74 R.C.38 radial. Designed by Ing.
Fabrizi, a pre-production batch of fourteen of the radial-engined F.5
fighter was built immediately prior to Italy's entry into the war, but
like most of Italy's fighters of this period the F.5 was under-powered
(maximum speed being 326 m.p.h.) and under-armed (two 12.7-mm. guns).
Nevertheless, a squadron was equipped with the F.5 for a short period
and employed for the night defense of the area surrounding Rome.
One of the fourteen F.5 fighters was re-engined in 1941 with a
1,050-h.p. DB 601 engine. This conversion was designated F.6, but the
most interesting development was the F.6Mz powered by the 1,250-h.p.
Isotta-Fraschini Zeta engine (which was also to have been installed in
the Reggiane Re 2004). The F.6Mz flew for the first time late in 1942
and was to have carried an armament of four 12.7-mm. guns or two
12.7-mm. and two 20-mm. guns. Maximum speed was 404 m.p.h., but the Zeta
engine was insufficiently developed for operational service, and the
F.6Mz progressed no further than the prototype stage.
C.A.N.S.A.: The Costruzioni Aeronautiche Novaresi S.A. at Cameri, a
subsidiary of the Fiat Group, was primarily responsible for a series of
trainers, such as the C.5 and C.6 biplanes of 1940 and 1942
respectively, and the C.4 training monoplane of 1942. In 1940,
C.A.N.S.A. produced two prototypes of the F.C.12, which was intended as a
trainer for dive-bomber pilots but was also projected as a light attack
bomber. The F.C.12 was a tandem two-seat monoplane powered by a
600-h.p. Fiat A.30 R.A. in-line engine. Armament comprised two 12.7-mm.
guns in the fuselage and two 12.7-mm. guns in the wings, and a
manually-operated 12.7-mm. gun in the rear cockpit.
In the following year C.A.N.S.A. produced the F.C.20 reconnaissance
bomber powered by two 840-h.p. Fiat A.74 R.C.38 radials, and the
F.C.20bis, which was intended for ground attack and carried a 37-mm.
cannon in the Dose. The final development of the design was the F.C.20
quater of 1943, which was similar to its predecessor apart from the
engines, which were two 1,150-h.p. Daimler-Benz DB 601s. These increased
maximum speed from 261 m.p.h. to 311 m.p.h.
C.M.A.S.A.: The Costruzioni Meccaniche Aeronautiche S.A., with works at
Marina di Pisa, was another subsidiary of Fiat, being incorporated in
the Group in 1931. The major wartime activity of this concern was the
development and production of the R.S.14, the prototype of which was
flown in 1938. The R.S.14 was powered by two 840-h.p. Fiat A.74 R.C.38
radials, and the production models, the R.S.14B and R.S.14C, differed
from the prototype in having a ventral gondola to house torpedoes or
bombs. In 1942, this concern produced a land-based version of the R.S.14
A.S.14. Similarly powered to the floatplane, the A.S.14 was intended
for the ground-attack role and it was proposed to install a 45-mm.
cannon in the nose. The sole prototype of the A.S.14 was destroyed at
Guidonia in September 1943.
In 1939, C.M.A.S.A. had been building the C.S.15 powered by the
experimental 2,250-h.p. Fiat A.S.8 engine. The C.S.15 was de- signed for
an attempt on the World Air Speed Record and employed surface
evaporation cooling. Estimated maximum speed was 528 m.p.h., but
construction of the prototype was suspended when Italy entered the war.
The plant also produced a conversion of the Fiat 0.50 Freccia
single-seat fighter as a tandem two-seat advanced trainer.
designated 0.50B, and the prototype flew for the first time on 30th
April 1940, but no production of this version was undertaken. The
C.M.A.S.A. design office undertook the conversion of a Fiat 0.50 to take
the 1,050-h.p. Daimler-Benz DB 601 in-line engine. This conversion,
which flew on 15th August 1941, was designated 0.50Y and attained a
maximum speed of 360 m.p.h. It served to provide data for the Fiat 0.55
Centauro-one of the best fighters produced in Italy during the war.
Production ceased at the Marina di Pisa works after extensive damage had
been caused by bombing in 1943.
FIAT: Aeronautica d'Italia S.A. (Fiat) was perhaps the most powerful
organization within the Italian aircraft industry and certainly the most
prolific.Its aircraft were exported all over the world prior to the
war, and it supplied a substantial proportion of the equipment of the
Regia Aeronautica. It was also the last of the world's major aircraft
manufacturers to produce fighter biplanes. When Italy entered the war
many of her second-line fighter squadrons and attack elements were
equipped with the Fiat C.R.32 which, designed by Ing. Rosatelli, had
first flown as far back as 1933. Despite the fact that it appeared
antiquated even by standards obtaining in the mid 'thirties, this little
fighter biplane was produced in substantial quantities right up until
the outbreak of World War Il. Powered by a 600-h.p. Fiat A.30 R.A.
engine, it had a maximum speed or 248 m.p.h., and production versions
included the bis, ter and quater. It was also produced under license in
Spain as the Hispano HA-132-L Chirri.
The C.R.42 Falco was widely used as a bomber escort and
subsequently relegated to the assault role with two 220-1b. bombs. In
1940, C.M.A.S.A. built an experimental twin-float version of the C.R.42,
and another experimental version featured a retractable undercarriage.
This fighter was also exported to the air forces of Sweden and Hungary.
Ing. Rosatelli was also responsible for the design of the B.R.20 bomber
of 1936. A modern twin-engined low-wing monoplane, the B.R.20 was in
complete contrast to Rosatelli's biplane fighters and quantity
production was initiated. The initial production model was powered by
two 1,030-h.p. Fiat A.80 R.C.41 radials, and 350 machines of this type
were built between 1937 and 1940. In 1939 the B.R.20M (Modificato)
appeared, featuring a redesigned nose section and other refinements, to
be followed in 1941 by the B.R.20bis with 1,250-h.p. Fiat A.82 R.C.42jS
engines and increased armament (one 12.7-mm. gun in a power-operated
dorsal turret, and manually-operated guns in the nose, a ventral
position and side blisters). A total of 250 B.R.20M and B.R.20bis
bombers were built during the war years. The B.R.20 was dubbed Cicogna
Other Rosatelli designs were the C.R.25 and the C.R.23. The C.R.25,
which first flew in 1939, was designed as a long-range escort fighter.
It was powered by two 840-h.p. Fiat A.74 R.C.38 radial engines which
provided a top speed of only 273 m.p.h. at 13,123 ft., and a range of
932 miles. Armament comprised three machine guns and a 1,550-lb. bomb
load. Only a pre-production batch of ten C.R.25 aircraft was completed,
one of these being used as a personal transport by the Italian air
attaché in Berlin. The remaining nine aircraft were actual1y used for
convoy escort late in the war and were, on one occasion, engaged by
Beaufighters. The C.R.23 was a fighter-bomber powered by two 1,550-h.p.
DB 603 engines and carrying an armament of four 20-mm. Mauser cannon and
one 12.7-mm. machine gun. Construction of a prototype began in 1943 but
was not completed.
Also in the equipment of the Regia Aeronautica was the series of
single-seat fighters designed by Ing. Gabrielli. The first of these, the
Fiat G.50 Freccia, flew in prototype form on 26th February 1937, and a
small production batch was built far the Regia Aeronautica. The major
production model of the Freccia, the G.50bis, flew far the first time on
13th September 1940, and although similarly powered to the first
version (840-h.p. Fiat A.74 R.C.38) and carrying the same armament (two
12.7-mm. Breda-Safat guns) it had a reduced all-up weight which resulted
in a slightly improved speed and range, and relinquished the cockpit
canopy of the former. The G.50bis/A, which first flew on 3rd October
1942, was similar but carried two additional machine guns in under wing
gondolas. Approximately 350 G.50bis fighters were built, and some of
these were supplied to Finland and Croatia.
Reference has already been made to the G.50B trainer produced by
C.M.A.S.A., but a little-known experimental version was the G.50ter
powered by a 1000-h.p. Fiat A.76 R.C.40/S radial (first flown on 17th
July, 1941) which increased maximum speed from 293 m.p.h. to 329 m.p.h.
The G.51 was a projected development of the G.50 with an A.75 R.C.53
engine, and the G.52 was another projected version with a DB 601N engine
and derived from the G.50Y developed by the C.M.A.S.A. plant.
Progressive development of the basic Freccia design resulted in the
G.55 Centauro powered by the 1,475-h.p. Daimler-Benz DB 605 in 1942. The
Daimler-Benz engine was built under licence by Fiat . as the R.A.1050
and was installed in the production Centauro, deliveries of which began
in 1943. The initial production model, the G.55/0, carried an armament
of four 12.7-mm. Breda-Safat machine guns and one 20-mm. Mauser cannon.
This was succeeded by the G.55/I with two 12.7-mm. and three 20-mm. guns
and, finally, by the G.55/11 with five 20-mm. cannon. The G.55S
(Scorta) escort-fighter variant carried a long-range fue1 tank under the
fuselage. Production deliveries of the G.55 Centauro started too late
far this fighter to see active service with the Regia Aeronautica, but
production of this fighter was centered in the area of Ita1y occupied by
German forces and, after the armistice with Italy, production of the
Centauro continued in Northern Italy far the Fascist Repub1ican Air
Force fighting alongside the Luftwaffe. However, only about 100
Centauros had been delivered when Northern Italy was overrun by the
The G .56 was a further development of the Centauro, differing in
having a 1,510-h.p. DB 6O3A engine. The sole prototype of the G.56 flew
on 28th May 1943 and no production was undertaken. The G.57 was a
projected version which reverted to a radial engine, the 1,250-h.p. Fiat
A.82 R.C.24-52, but no prototype of this version was tested.
Ing. Gabrielli was also responsible far the G.12 transport, designed
before the war far high-altitude Alpine crossings. The first prototype,
the civil G.12C with accommodation far fifteen passengers, flew on 15th
October 1940, and the first military transport version, the G.12T, which
could carry twenty-two fully-equipped troops, flew on 15th May 1941. A
number of G.12T transports were delivered to the Regia Aeronautica,
being used notably during the Tunisian fighting, and the type was
powered by three 770-h.p. Fiat A.74 R.C.42 radials.
I.M.A.M. (ROMEO): The S.A. Industrie Meccaniche e Aeronautiche
Meridionali of Naples was, until 1936, when it was absorbed by the Breda
Group, the S.A. Industrie Aeronautiche Romeo. Before the war this
concern produced several original designs which were produced in
quantity, such as the Ro 37 and Ro 37bis two-seat reconnaissance
biplanes, the Ro 43 two-seat fighter-reconnaissance floatplane, and the
single-seat Ro 44 float-plane fighter biplane. The I.M.A.M. Ro 51 was
another of the single- seat interceptor fighter monoplanes produced to
meet similar requirements to those fulfilled by the Macchi C.200 Saetta
and the Fiat G.50 Freccia in 1937-38. Powered by an 840-h.p. Fiat A.74
R.C.38 radial, the Ro 51 was a low-wing monop1ane with a fixed
undercarriage and the usual armament of two 12.7-mm. Breda-Safat guns.
second prototype was fitted with a retractable undercarriage and a
third with a single central float and outboard stabilizing floats, being
intended as a replacement catapult fighter far the Ro 44. Neither water
nor land-based variants of the Ro 51 were placed in production.
In 1939, Meridionali projected a twin-engined single-seat fighter, the
Ro 57. Powered by two 840-h.p. Fiat A.74 R.C.38 radials, the Ro 57
carried two 12.7-mm. and two 20-mm. guns in the nose, and attained a
maximum speed of 304 m.p.h. Designed by Ing. Giovanni Galasso, the
I.M.A.M. Ro 57 began to leave the production lines of the Naples factory
early in 1942, and entered service in small numbers with Regia
Aeronautica fighter elements defending Italy. Performance of the Ro 57
proved to be inadequate for fighter requirements, and the design was
adapted for the assault role by the attachment of dive brakes and an
under-fuselage crutch for bombs up to 1,100 lb. The assault version was
designated Ro 57bis.
Two further original designs produced by Meridionali as prototypes were
the Ro 58 and the Ro 63. The Ro 58 was a two-seat heavy fighter similar
in conception to the Me 110. Powered by two 1,050-h.p. DB 601 engines
and of all-metal construction, the Ro 58 was flown at the Guidonia test
establishment in 1943 and proved to be a particularly promising design.
Armament comprised five forward-firing 20-mm. cannon (three in the nose
and two in a blister under the fuselage), and a manually-operated
12.7-mm. gun in the rear cockpit. Maximum speed was 376 m.p.h. at 17,000
ft., and normal range was 932 miles.
The Ro 63 was a small, three-seat artillery observation and liaison
monoplane powered by a 250-h.p. Hirsh H.M.508D engine. The Ro 63 could
take off in a distance of 200 ft. and land in 180 ft., and quantity
production orders were placed although deliveries had not commenced at
the time of the armistice. The major wartime activities of the
Meridionali plants at Bufola, Vasto and Capodichino were the series
production of Breda Ba 88, Cant Z.1007bis and Cant Z.1018 bombers.
REGGIANE: One of the many companies controlled by Count Gianni Caproni,
the Officine Meccaniche "Reggiane" S.A. of Reggio began aircraft
production in 1937 with a variant of the P.32bis (referred to under
Piaggio) which was originally deve1oped from the Ca 405C Procellaria.
The Ca 405C was designed by Reggiane to establish several international
records and powered by two 850-h.p. Isotta-Fraschini Asso XI. R.C.40
liquid-coo1ed engines, featured double-slotted high-lift flaps. The
P.32bis was virtually a redesigned bomber version of the Ca 405C, and
the variant built by Reggiane featured a 1engthened fuse1age.
Simultaneously, Reggiane built the Savoia-Marchetti S.M.79 Sparviero
The Reggie design office is best known for the series of single-seat
lighters that it produced for the Regia Aeronautica. The first of these,
the Re 2000 Falco I (readers will note that the Fiat C.R.42 was also
dubbed "Falco"), designed by Alessio and Longhi, was a delightful little
aeroplane, despite its bulky radial engine, and was demonstrated at
Guiding in 1938. Its powers of maneuver were undoubtedly superior to
those of its nearest competitor for production orders, the Macchi C.200
Saetta, and it was favored by the Guidonia test pi1ots, but the
prototype suffered structural deficiencies which, together with
difficult maintenance, dictated the choice of the Saetta far the Regia
Aeronautica. However, several export orders for the Falco I were obtained
(notably from Sweden, here it was designated J 20, and Hungary, where
it was known as le Héjja and later built under license), and production
However, with Italy's entry into the war, the Re 2000 was taken over by
the Regia Aeronautica, later serving in Greece and North Africa, where
its maneuverability delighted its pilots but its armament of two
12.7-mm. Breda-Safat machine guns proved totally inadequate. The
prototype had been powered by a 1,030-h.p. Fiat A.80 R.C.41 radial, but
this was primarily a bomber engine and not entirely suitable as a
fighter power plant. Consequently, the production model of the Re 2000
employed the 986-h.p. Piaggio .XI R.C.40 which provided a top speed of
332 m.p.h. at 16,400 ft. one Re 2000s were adapted as fighter/bombers
with a 440-lb. bomb slung under the fuselage, and in 1942 a series of
experiments l catapult launching were conducted from the deck of the
In 1940 a number of Daimler-Benz DB 601 engines of 1,050 h.p. had
arrived from Germany and been distributed to various Italian fighter
manufacturers far experimental purposes. One of these was installed in a
modified Re 2000 airframe, resulting in a considerable improvement in
climb rate and ceiling. This version was designated 2001 Falco II, and
production deliveries commenced in 1941, first being used by the 2nd
Gruppo Caccia and appearing aver Malta early in 1942. Initially, the
Falco II carried the same armament as s predecessor, but the first
production machines had two 7. 7-mm. machine guns in the wings,
supplementing the two 12.7-mm. guns, and in the Re 2001CN (Caccia
Notturna) night fighter and the 2001H, the 7.7-mm. guns were
supplemented by two 20-mm. Mauser cannon in underwing gondolas. The Re
2001G was a fighter/bomber variant carrying a 440-lb. bomb in an
under-fuselage crutch which cou1d be swung forward to clear the airscrew
for diving attack.
Development of the original radial-engined Falco I was continued
side-by-side with the inline-engined Falco II, resulting in the 2002
Ariete, which appeared in service in 1942. The Re 2002 Ariete was first
employed by the 5th and 50th Stormi (previously operating Ba 65 and Ba
88 attack aircraft) as a fighter/bomber, and was powered by a 1125-h.p.
Piaggio P.XIX R.C.45 radial enclosed in a neat, Mercier-style cowling.
The Re 2002 was used for a series of trials with a naval torpedo slung
under the fuselage, and when used for the escort tasks with an
under-fuselage drop-tank, was designated Re 2002S (Scorta). The Re
2002bis was an experimental version with a sideways-retracting
undercarriage which was later employed by the Re 2005 Sagittario.
The Re 2003 was an experimental tandem two-seat reconnaissance-bomber
variant of the original Re 2000. Only two prototypes of the Re 2003 were
built. The Re 2004 was a projected development powered by a 1,250-h.p.
Isotta-Fraschini Zeta R.C.42 (similar to that installed in the Vizzola
F.6Mz) with which a maximum speed of 385 m.p.h. was expected.
Availability of the German DB 605AL engine of 1,250 h.p. led to the
abandoning of the Re 2004 in favour of the Re 2005 Sagittario.
The Sagittario embodied considerable structural redesign, being fitted
with a longer fuselage and an outward-retracting under- carriage (first
tested on the Re 2002bis), and possessed the then exceptionally heavy
armament (by Italian standards) of three 20-mm. Mauser cannon and two
12.7-mm. Breda-Safat machine guns. The Sagittario was first operational
aver Sicily early in 1943 with the 320th Fighter Squadron (22nd Gruppo)
but did not reach operational service in large numbers, although it was
flown by German and Rumanian pilots after the signing of the armistice
between Italy and the AIlies. The Re 2005R was to have had a
supplementary propulsion unit of the Campini type; the Re 2006, with a
1,350-h.p. DB 603 engine, was on the drawing boards at Reggio when
SAVOIA-MARCHETTI: The Societa Italiana Aeroplani "Savoia- Marchetti"
was the major manufacturer of bombing aircraft far the Regia Aeronautica
from the early 'thirties, when the first of the Savoia-Marchetti bomber
tri-motors, the S.M.81 Pipistrello, was delivered to the bomber
squadrons in 1934. The Pipistrello first saw active service in Ethiopia
and subsequently in Spain. It was powered by three 700-h.p. radiaIs and,
with its fixed undercarriage, had a maximum speed of only 217 m.p.h.
Despite its obsolescence, the S.M.81 Pipistrello still served with the
Regia Aeronautica when Italy entered the war, being used as a night
bomber in Greece and North Africa.
The most important product of the Savoia-Marchetti factories was
undoubtedly the S.M.79 which, although possessing an earlier type number
than that of the Pipistrello, did not actually enter service until
1936. The S.M.79 originally appeared in 1935 as an eight-passenger
commercial monoplane powered by three 650-h.p. Alfa Romeo 125 R.C.35
radials but the initial bomber production version was powered by three
850-h.p. Alfa Romeo 126 R.C.34 radials. Simultaneously, the
Savoia-Marchetti design office developed a twin-engined version of the
design, the S.M.79B, featuring a completely redesigned nose section to
house a bombardier. The S.M.79B was intended primarily for export, and
in 1936 this type won the Military Aircraft Competition organised by the
Argentine Government-during this competition the Italian pilot executed
four /oops-and was awarded an order. The S.M.79B was powered by two
1,030-h.p. Fiat A.80 R.C.41 engines and had a maximum speed of 276
m.p.h. The S.M.79B was also built under license in Romania for Romanian
Air Force bomber elements, Romanian-built aircraft being powered by two
1,100p. Junkers Jumo 2llF liquid-cooled engines, but no machines were
delivered to the Regia Aeronautica.
The second production version of the S.M.79 (named Sparviero) was the
S.M.79-II powered by three 1,000-h.p. Piaggio P .XI R.C.40 radials which
increased maximum speed from 267 m.p.h. to 295 m.p.h. The final
production series of the Sparviero, the S.M.79-III, was an improved
version which was used after the armistice by the air arm of the
Republica Sociale Italiana, which operated in concert with the
Luftwaffe. The S.M.79-III could be employed as a torpedo bomber,
carrying one or two torpedoes externally under the fuselage, and some
machines had their defensive armament augmented by a forward-firing
20-mm. cannon. One Sparviero was used as a radio-controlled flying bomb
on 13th August 1942, being directed against British warships off the
Algerian coast. However, owing to a fault in the radio circuit, the
aircraft crashed in the mountains of K1enchela.
The S.M.82 Marsupiale, which appeared in 1938, entered service in 1941
and was employed as a long-range heavy bomber pending the availability
of the Piaggio P.l 08B. The Marsupiale was used far bombing raids on
Palestine and Bahrain Island, and had an unusual central bomb-aimer's
position which retracted into the fuselage.
However, the major wartime function of the Marsupiale was that of heavy
transport. In 1942 a Marsupiale flew from Rome to Tokyo with a Campini
power plant that had been purchased by Japan for research purposes.
The S.M.84 (which designation originally caused some confusion as the
S.M.84B was a twin-engined commercial transport of pre- war design
derived from the S.M.73) was a further bomber tri- motor used
extensively in the Mediterranean. The S.M.84, powered by three
I,000-h.p. Piaggio P.XI R.C.40 radials, was first reported in action
against British shipping in the Mediterranean in November 1941, and soon
after its appearance succeeded in scoring a torpedo hit on the
battleship Ne/son. The S.M.84 had a defensive armament of five machine
guns and could carry two torpedoes side by side under the fuselage.
The S.M.85 and S.M.86 were both light, twin-engined dive- bombers of
pre-war design the S.M.85 was powered by two 460-h.p. Piaggio P.VII
R.C.35 radials and a small production batch was built. However, the type
was unsuccessful and never used operationally. The S.M.86 was a
development of the S.M.85 powered by two 520-h.p. Walter Sagitta engines
which progressed no further than the prototype stage. Another
experimental prototype was the S.M.87 twin-float seaplane transport
version of the land- based S.M.75. The S.M.87 was powered by three
960-h.p. Pratt and Whitney SG 3G radials.
In 1943, Savoia-Marchetti completed the prototypes of four assault
aircraft, the S.M.89, the S.M.91, the S.M.92 and the S.M.93 (the S.M.90
was a commercial transport powered by three 1,400-h.p. Alfa Romeo 135
R.C.32 radials). The S.M.89 was virtually a twin-engined development of
the S.M.84, with the wings of the earlier aircraft and two 1,350-h.p.
Piaggio P.XII R.C.35 radial engines. The S.M.89 carried a forward-firing
armament of two 37-mm. cannon and three 12.7-mm. machine guns in the
nose, and a further 12.7-mm. gun in a dorsal turret. Maximum speed was
286 m.p.h. at 17,388 ft. The S.M.91 and S.M.92 were both two-seat
twin-boom fighter-bombers powered by two 1,475-h.p. DB 605 engines. They
differed primarily in that the S.M.91 possessed a central cockpit
nacelle between the twin booms, whereas the S.M.92 carried both crew
members in the port boom (like the Caproni Ca 380 Corsaro). The armament
of the S.M.91 comprised four 20-mm. cannon and two 12.7-mm. machine
guns (in the wing roots) firing forward, and one manually-operated
12.7-mm. gun far rear defence. The S.M.92 had a forward-firing armament
of three 20-mm. cannon (one firing through the airscrew hub of the
starboard engine and two mounted in the wing centre section) and four
12.7-mm. guns mounted in two pairs under each engine. Rear defence was
provided by a 12.7-mm. gun installed in a remotely- controlled barbette
mounted centrally on the tailplane.
Savoia-Marchetti's final wartime prototype was the S.M.93 dive-bombing
and ground attack aircraft. The S.M.93 carried a crew of two, the pilot
lying in a prone position, and power was provided by a 1,475-h.p. DB 605
engine. Armament comprised one 20-mm. cannon firing through the
airscrew hub, one 12.7-mm. gun in each wing and one manually-operated
12.7-mm. gun fired by the observer. Maximum bomb loads included 1,800
lb. under the fuselage and 1,400 lb. under the wings, and maximum speed
was 337 m.p.h. at 22,975 ft. Only single prototypes were built of each
of the last four aircraft mentioned.
