Douglas XBT2D/AD Dauntless II/Skyraider 

The Douglas XBT2D Dauntless II was a prototype design for a large, single seat, carrier-capable naval dive bomber/torpedo bomber designed in the second half of WWII.  It took its first flight on 18 March 1945, and would be further developed into the AD (later A-1) Skyraider that would serve with the US Navy and US Air Force through to the end of the Vietnam War.  The XBT2B was a prototype aircraft and the AD-7 was the final variant of this type aircraft produced, and was redesiganted the A-1J in 1962.

Per Reference [8] a total of 3,180 AD/A-1 aircraft would be built between 1945 and 1957, including some configured as Airborne Early Warning (EAW) aircraft, with a large belly mounted radar and radome.  AD/A-1 aircraft would serve not only with the US Navy and US Airforce but also the UK, France, Sweden, South Vietnam, Cambodia, the Central African Republic, Chad and Gabon.
