Grumman F4F Wildcat was a US Navy carrier-based mainstay fighter aircraft in action during the early stages of the Pacific War. Although it had the abilities necessary to a carrier-based fighter aircraft, the enemy was too tough. It was totally inferior to its rival the Zero in speed, rate of climb, and maneuverability, and was constantly put under pressure during hard fighting. Because of this, it competed tactically against its rival the Zero, using tactics such as 'hit and run' and 'weave,' and somehow managed to hold out until the arrival of its successor, the F6F Hellcat. On the other hand, it achieved military gains in Europe by making use of its low wing loading, which is characteristic of carrier-based aircraft, in dogfights with the German rivals that placed emphasis on speed.
