Notes:
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. While originally considered a version of the He 177, growing incompatability of parts led to the redesignation to He 274 and reassignment of the project to SAUF. French resistance workers conspired to slow down development of the He 274 so that the prototypes were not ready at the time of the German withdrawal in July 1944. The French took possession of the prototypes and redesignated them ASA 01A. The prototypes finally flew in December 1945 with French markings.
