GRUMMAN F4F-4 vs. CURTISS P-40F

 

The Report: U. S. NAVAL AIR STATION, ANACOSTIA D. C., 19 September 1942.

 

The tests were performed between 21 June 1942 and 19 August 1942 and military power was used.

 

     6. The F4F-4 was compared to the P-40F to determine relative climb, speed and turning ability. At the continuous engine ratings the F4F-4 is superior in climb, the superiority increases with altitude, and is inferior in level speed below 20,000 feet. At the maximum ratings the P-40F is superior in climb below 15,000 feet and in level speed below about 22,000 feet. At higher altitudes the F4F-4 is superior in all respects. It is superior in turning ability at all altitudes, and in vision and general handling qualities.

America's Hundred Thousand, Pilot Notes on the F4F-4:

     The F4F-4 was noted as very inferior to the best Japanese fighters as performance

was not satisfactory.

     One of the reasons for the low opinion held of the F4F-4 concerned limited range and

endurance which adversely affected operations from a carrier. Pilots felt it had increased

fuel consumption rates compared to earlier versions.

     Other factors cited against the F4F-4 vs. earlier F4F-3 & F4F-3A were lower climb rates

and poorer maneuverability. Many pilots felt the F4F-4 was completely outclassed by the

Japanese Zero. Pilots also felt the F4F-4 when carrying two external fuel tanks was a

particular dog.

     The narrow tread of its landing gear made for difficulty in cross wind taxi and also on

the take-off run.

     What the F4F-4 lacks in climb and maneuverability is more than compensated for by

its excellent armament, protective armor, protected fuel system and greater strength; let

us not condemn our equipment; it shoots down the enemy in flames, and gets most of us

back to our base.

     A pilot on Guadalcanal noted the Wildcats were able to climb to 34,000 ft. to await a

Japanese attack on Henderson Field.

     The F4F-4 was the new model redesigned for folding wings and 6 x 0.5 in machine

guns instead of four but with considerably less ammunition per gun. The shorter firing

time allowed greatly upset pilots. "The F4F-4 supply of 240 rpg. was insufficient." "The

reduction of rounds cut the firing time by at least five seconds. That doesn't seem like

much, but it can be a lifetime in combat."

     The FM-1 and FM-2 versions went back to four guns with more ammunition per gun.

The British, who instigated the six gun arrangement of the F4F-4 used for commonality

of manufacture stayed with this configuration.

     The F4F-4 was much less maneuverable than the earlier models. It was considered

unresponsive and generally sluggish when compared to the F4F-3 & F4F-3A. It was

sometimes referred to as an overloaded clunker. Page 490.

     Wildcats had an excellent reputation for standing up well under enemy fire. " It was

a tough little fighter", "it could take a lot of punishment", "We stayed in business after

being hit repeatedly". "The F4F- was as solid as a brick outhouse, almost a flying tank."
