500 examples - 42-83663 (c/n 97-15881) to 42-84162 (c/n 97-16380) - were built, with the 23rd A-36A - 42-83685 (c/n 97-15903) - being passed to the RAF as EW998. EW899 was evaluated as the Mustang Mk I (Dive bomber) but was felt by pilots to offer no major advantages over the standard Mustang Mk I.
A-36As arrived in North Africa in April 1943, commencing operations on 6 June by participating in a fighter bomber assault on Pantellaria. The A-36As spent the following weeks serving with the 27th and 86th Fighter Bomber Groups in Morocco, before joining 12th Air Force for operations in Sicily and Italy. A-36As also served with the 311th Fighter Bomber Group in India, losing 177 aircraft before the type was withdrawn. On the plus side, the type was capable of combatting other aircraft, with 84 aerial victories being credited to A-36 pilots of the 27th Fighter Bomber Group, including Lieutenant Michael T. Russo, the only pilot to become an ace in the Allison powered Mustang.
