Macchi vs U.S. Fighters




By Barrett Tillman

Italy’s finest WW II fighter was a sleek, good-looking machine with the kind of aesthetics expected of an artistic people who produce world-class racecars. But the Darwinism of aerial combat paid little benefit for appearance, as the MC.202 fared poorly against its American competitors in almost every category. The P-51D and P-38L were 40 to 60mph faster at most altitudes and packed a far more lethal punch. The Macchi’s two 12.7mm machineguns simply could not match the American .50 calibers, let alone the Lightning’s 20mm cannon. The Folgore pilot’s main advantage was maneuverability—an asset negated by intelligent opponents with greater speed on the level and in the dive. Furthermore, the Mustang and Lightning possessed nearly three times the 202’s range, which permitted Allied bomber formations to arrive over Italian bases with powerful fighter escort.

NOTES: I suspect the G figures are apples and oranges: Italian is the pull-the-wings off figure while the U.S. are RATED, which does not include the (50%?) safety margin.
The usually listed P-51 cruise of 362 is batguano. Unless it was a short mission, you’d run out of fuel at that rate irregardless of external tanks. I know for sure that on VLR missions from Iwo to Japan, the Mustangs loped along at 220 indicated.
