T-28D教練機捨去T-28A所用的R-1300-1A型活塞螺旋槳發動機,而改用出力達1,300匹馬力的萊特(Wright)R-1820-56型活塞螺旋槳發動機,其與T-28A教練機外觀上最大的差異為螺旋槳葉片數由2葉變成3葉。
The first production, as T-28A, numbered 1,194 planes, then the Navy got their T-28B in 1952, differing in having a more powerful engine to replace the 800hp Wright R-1300, and a two-part canopy, plus structural modifications for duty aboard carriers. For counter-insurgency combat, Trojan was again revised, this time as the single-seat T-28D, with armament and rocket-launchers. When production ended in 1957, North American had built a total of 1,948 of these three versions.
