Republic P-47D Thunderbolt

The P-47 Thunderbolt was one of the most successful American fighters of World War II. The initial concept for the Thunderbolt was a lightweight interceptor, the aircraft that eventually came out of the Republic factories was the largest and heaviest single-seat fighter ever accepted by the Army Air Forces. The Thunderbolt made its debut as a long-range escort fighter, but the plane really made its name as a fighter-bomber. The P-47s heavy armor and eight machinegun armament made it perfect for strafing and rocket attacks near the front lines. The P-47D is the most built version of the Thunderbolt with over 12,000 constructed. Unusually, the P-47D underwent a major design change mid-way through the production run without a corresponding change in the letter designation. The early D models had a high rear deck that came up behind the pilot's head. This caused a significant blind spot to the rear. In late 1943 the design was modified to lower the rear deck and incorporate a bubble canopy that eliminated the blind spot.
