In 1938 the body of future aircraft carrier 'Graf Zeppelin' was developed. The Messerschmitt company developed the aircraft modification Bf 109T-0 to serve as board fighter. First aircraft Bf 109T-1 was built in 1941. The aircraft had DB-601N engine 1200 hp. The wings could be folded manually. Since aircraft carrier has not been finally built, the fighters were modified to Bf 109T-2 version. The catapult joints and landing hook were dismantled. In total 60 aircraft of Bf 109T type were built.
