The A-24B (US Navy SBD-5) arrived in 1943 powered by the 1,200-hp Wright R1820-60 engine. The 407th Bomb Group, assigned to the 11th Air Force, flew A-24Bs against the Japanese held island of Kiska, Alaska, during July and August 1943. From December 1943 until March 1944, the 531st Fighter Squadron of the 7th Air Force flew A-24Bs from Makin Island in the Gilbert Islands against Japanese controlled islands in the Marshall Islands. The A-24Bs were then withdrawn from combat.
The B model was similar to the previous A-24 model but had a more powerful engine than either the A-24 or A-24A. As a result, A-24B could fly slightly faster and higher than the earlier models. The A-24B lacked the small air intake on the top of the engine cowling present on the earlier models and is an easy way to distinguish the B model.
