This contrasted with Allied fighters, such as the Warhawk and Wildcat, which though less maneuverable, were extremely rugged and difficult to bring down. Nevertheless, the Zero was responsible for destroying at least American aircraft between 1941 and
Henschel (Hs-126): The first prototype was not entirely up to Luftwaffe standards and it was followed by two more development planes equipped with different engines. Following the third prototype, ten pre-production planes were built in 1937. The Hs- 126 entered service in 1938 after operational evaluation with the Legion Condor.
