This was somewhat ironic as Douglas was designing/building the huge Skywarrior at the time, which could launch from a carrier at weights around 68,000lb. With curiosity piqued, the US Department of Defense asked Heinemann to give a presentation in early 1952 and in June the Navy asked Douglas to produce two prototype XA4D-1 attack aircraft of just 12,000lb empty (later pushed to 14,000) and a gross weight of 30,000lb. Speed of the aircraft should be around 576mph with combat range in the region of 896 miles – and all for around $1 million per aircraft. It would carry an unspecified weapon of some 2,000lb – an atom bomb. Legend has it that Heinemann claimed to be able to make the Douglas jet go around 100mph faster, be half the weight specified and still cost less. He then sketched his design and sat down the El 90 July 2021 // www.Key.Aero to use only 80 parts instead of 240 and to weigh just 40lbs, not 92. The first machine, the XA4D, was rolled out in June 1954 and weighed just 7,896lb – some 270lb below Douglas’ own ‘empty’ target weight. It was powered by a Curtiss- Wright J65 engine – a licensed British A-4 SKYHAWK: Bristol Siddeley Sapphire.
