No it was a version of the P-51A.The A-36 had two .50's in each wing and two in the nose, but they were in the bottom of the fusalage.
The only USAAF Mustangs with 20 mm cannon were the 57 F-6A recon birds. The British Mk. IA also had 20 mm cannons, but the US didn't use that version. According to my sources, the Brits received 97 Mk. IAs.<S>Shubie
Sorry Ranger but it was not the P-51A but the P-51 (no letter). The A-36 was based on the British Mustang I. The Mustang Ia had the 4 20mm cannons. The P-51A was the British Mustang II.
Thanks for the correction, though I'm not sure that the A-36 was based on any Mustang, I thought the A-36 came along before any version of the Mustang.
With no funds for pursuit aircraft, as fighters were then called, Lt. Kelsey came up with a way to beat the system and get some additional Mustangs on order for the USAAC. Using some remaining funds for attack aircraft, Kelsey asked North American to develop a dive bomber version of the NA-73. Choosing A-36, which was the next available attack designation, Kelsey ordered 500 of these dive bomber versions on April 16, 1942.
So the British Mustang Ia had the birdcage canopy, dive flaps and cannons?
Why do only the american planes have bubble canopies?
