The Heinkel He 274 was a German heavy bomber design developed during World War II, purpose-designed for high-altitude bombing with pressurized crew accommodation. Due to the Allied advance through North-west Europe, the prototypes were abandoned at the French factory where they were being built.

The He 274 was designed to be a fast and highly maneuverable bomber, capable of carrying a significant payload. It was intended to replace the He 111 but was hampered by technical problems and material shortages.

heinkel he 274 Originally designated He 177 A-4, the He 274 was a high-altitude development of the He 177. Like the He 277, the He 274 dispensed with coupled engines and mounted four single powerplants.

He 274-V1 was ready for flight in July 1944, but the Allied offensive forced the Heinkel employees working on the project to be evacuated, the engines were blown up by explosive charges, after which the Germans, capturing all the blueprints, fled.

In July 1944, after gaining a foothold in Normandy in June, the Allies began their offensive against German territory throughout northern France. This forced Heinkel workers to leave their jobs, even as the first prototype, the He 274 V1, approached its flight stage.
