It was the work of Ed Heinemann, the Douglas designer also responsible for the A-1 Skyraider and the <a href=\"https:\/\/migflug.com\/aircraft\/a-4-skyhawk\">A-4<\/a> Skyhawk.

Photo: U.S. Navy \/ Wikimedia Commons.<\/figcaption><\/figure>\n<h2 style=\"padding-top:22px\">Straight up<\/h2><p>If the speed record made the Skyray famous, its climbing made it legendary. In 1958, Marine Major Edward N. LeFaivre set five world time-to-climb records over two days. In one run, the Ford went from a standing start on the runway to 49,221 feet in two minutes and 36 seconds, holding a 70-degree nose-up angle &mdash; climbing very nearly straight up. A big wing, a light airframe and the powerful J57 turned it into something close to a piloted rocket.<\/p><h2 style=\"padding-top:22px\">The engine that nearly killed it<\/h2><p>The Skyray was originally built around the Westinghouse J40, an engine that failed so badly it dragged down several U.S. Navy programmes of the era. The Ford survived only because Douglas re-engineered it around the Pratt &amp; Whitney J57. Once it was in service, it earned a unique distinction: the only U.S. Navy fighter ever assigned to the continental air-defence network alongside the Air Force&rsquo;s interceptors.<\/p><p>Its career was short &mdash; the Skyray was gone by the mid-1960s, overtaken by faster, longer-ranged fighters. But for a few years in the 1950s, the fastest and the steepest-climbing aircraft in the world was a manta-shaped jet the Navy flew off a carrier deck.
