Heinkel He 280 by p40kittyhawk on DeviantArtArgus As 104 pulsejet Archives - This Day in Aviation B-1
In an attempt to solve the fuel problems the He 280B-1 was to have been 2ft 7in longer than the A-1 and prototype aircraft. It would have been powered by the BMW 003 engine, and armed with 20mm or 30mm cannon - some sources say three cannon, while others go as high as six. Despite these changes the He 280B-1 was not accepted for production.
