Why This 'Unfinished' American Dive Bomber Became The Skyraider Overnight

In June 1944, at the Bureau of Aeronautics in Washington, Douglas chief engineer Ed Heinemann asked the U.S. Navy to cancel his own airplane. The Douglas BTD-1 Destroyer was already on order, 358 of them. On paper it beat the Navy's newest dive bomber, the Curtiss SB2C Helldiver: 2,300 horsepower against 1,900, a 3,200-pound internal bomb load against 2,000, and a published range of 1,480 miles. But it was heavy, complicated and late. Rear Admiral Lawrence Richardson gave Heinemann one night to offer something better. Heinemann, Leo Devlin and Gene Root walked back to the Statler Hotel, ordered hamburgers, and worked until 3 a.m. By noon the next day the Navy had approved the XBT2D-1. It became the Douglas AD Skyraider. Meanwhile the fleet was fighting with the Helldiver, "the Beast," an airplane Captain Jocko Clark of USS Yorktown had recommended scrapping entirely. On June 20, 1944, in the Philippine Sea, only 5 of 51 Helldivers landed safely back aboard their carriers. The Skyraider arrived too late for the war, and planners expected jets to replace it within a few years. Instead it carried 8,000-pound loads in Korea, flew the U.S. Navy's last aerial torpedo attack against the Hwachon Dam, shot down a MiG-17 over North Vietnam, and fought until 1975. Only 28 production Destroyers were ever delivered. Douglas built 3,180 Skyraiders. This is the story of how an unfinished dive bomber became the Skyraider overnight, and outlasted the Helldiver the Navy was forced to fight with.

SOURCES AND HISTORICAL NOTES
This video draws on official U.S. Navy records and published aviation histories. Key references include Frederick A. Johnsen's "It Really Did Carry the Kitchen Sink" (Naval History, U.S. Naval Institute, February 1996), which draws on Edward H. Heinemann and Rosario Rausa's "Ed Heinemann: Combat Aircraft Designer" (Naval Institute Press, 1980); E.R. Johnson's "Able Dog" (Aviation History, September 2008); Laurence M. Burke II's "Curtiss SB2C Helldiver: The Big-Tailed Beast" (Smithsonian National Air and Space Museum); and the Naval History and Heritage Command's H-Gram series and Korean War chronology. Additional records come from the National Naval Aviation Museum, U.S. Naval Institute Proceedings (July 1957), and the Museum of Flight in Rome, Georgia, which displays the last surviving BTD-1 Destroyer (BuNo 04959). Published BTD-1 figures vary between sources (334 vs 344 mph, 45 vs 48 ft span); this video uses Museum of Flight data. The Skyraider was not designed from scratch in one night. Heinemann's team had sketched the concept for weeks before the Statler meeting and refined it for months afterward. Viewer corrections welcome — accuracy matters.
