Douglas A-1 Skyraider
  During World War II the Navy began looking for a new dive-bomber torpedo aircraft to
    meet its changing tactical and operational requirements. Several planes, among them the
    AD's direct predecessor, the 
SB2D/BTD, were developed by
    the Bureau of Aeronautics. Design difficulties and over-weight problems, however,
    ultimately led to a decision not to produce the 
SB2D/BTD.
    This in turn led to a new design which incorporated the good features of the 
SB2D/BTD while overcoming its inherent difficulties. 
  
The AD series (later redesignated A-1) that emerged from the combined efforts of the
    Bureau of Aeronautics and Douglas, who was the contractor, had two particularly
    significant design aspects. First, great emphasis was placed on the importance of the
    stringent weight control policy. Secondly, the standard bulky, heavy bomb displacing gear
    was replaced by a light, explosive device which literally blew the bomb clear. In
    comparison with the most advanced operational dive-bombers in 1945, the AD's initial
    design compared most favorably with a 27 percent greater top speed and a capability of
    carrying up to 4,000 pounds of either bombs or torpedoes.
  
For the next 12 years there was constant improvement in the airplane up through the
    AD-7, and 3,180 Skyraiders were delivered to the Navy, many of which were used during the
    Korean Conflict and Vietnam War also.
