When work on the He 178 was discontinued in the autumn of 1939, effort was transferred to a more advanced twin-engined design which was to be powered by pairs of two new Heinkel turbojets, the HeS 8 and HeS 30. Neither engine was ready for flight when the Heinkel He 280 prototype airframe was itself complete and first trial flights, which began on 22 September 1940, were unpowered, the aircraft being towed to release height behind a Heinkel He 111. A pair of the HeS 8 engines was installed in March 1941 and Fritz Schafer made the first powered flight on 2 April. The engines were producing little more than 500kg thrust, however, and although available thrust had risen to some 600kg by early 1943 when the second and third prototypes were flown, in April of that year BMW 109-003 engines were adopted. Six further prototypes were built, the eighth with a V-tail, but the rival Messerschmitt Me 262 was selected for production and the He 280s were regarded only as useful research aids.

The HE 178 was a private venture against the wishes of RLM and the Goering minted Reichsflugzeugmeister E.Udet! lets see if anybody get,s that one? wich no doubt made him to commit suicide..also the D4H aka Aichi was a He112 TB dive Bomber Looser at the Flyoff vs JU87
I have read only 9 were built. do any exist today?
Hey wait a munite, Bell had two or three Tricle-gear planes flying before 1939. air cobra's.
This aircraft was developed with a nose gear, which was new at that time. The early Me 262 had a tail wheel, which caused problems with the exhaust of the engines. Later the Me 262 adopted the nose gear like Heinkel used it.
Do you know how wide the HE 280 is, or it's full dimensions???
Please contact me back
