Some background about the P-47 aircraft
P-47 quickly gained the nickname of Juggernaut (the mighty jug) from it's pilots. This being due to it's huge size for a fighter (the aircraft weighed over 5 tonnes even before it was loaded).
Later versions had a bubble canopy for increased pilot visability, the previous non-bubble types being known as razorbacks.
For bomber escort the P-47 suffered a lack of range when compared to a drop tank equipped P51 Mustang. The P51 was able to go all the way to the target with the bombers, even on the longest range sorties. P-47s would have to turn back early due to lack of fuel.
The heavy and powerful P-47 also needed it's own technique when up against fighters. The machine was best suited to shoot and zoom methods due to it's high speed performance but less than brilliant turning circle.
