Description
The Mustang was entering service with the RAF in 1941, before the USA joined WW11, and it first went into combat over the beaches of Dieppe in 1942.
The first USAAF Mustangs were shipped off the Burma in 1943 and when the 8th Airforce was suffering from the Luftwaffe due to no escorts available they tried to swap, with the 9th Airforce, its allocation of Mustangs for Thunderbolts.
The biggest problem the USAAF had with the Mustang was it was designed and built to a RAF specification and when the swapped the US Allison engine for the British designed Merlin they felt it inferior to their own designs.
This book reviews the development of this plane, along with its contemporises from the US point of view.
