The A-36 Apache is a derivative of the P-51A Mustang or Mustang I as it was known in RAF service. The A-36 was designed as a dive-bomber version of the famed fighter that was designed by North American engineers in a mere 90 days. Employing wing-mounted dive brakes and powered by the low-altitude optimized Allison V-12, the A-36 saw only limited use in USAAF and RAF inventories.

The A-36 Apache owned by the Collings Foundation is one of the few known to exist. It is currently under restoration in New Smyrna Beach, FL.
