Says Pete Feigal, former Pro Military Artist for 25 Years:
The P-47 Thunderbolt was the best, most versatile single-engined fighter of WWII. Period. It was the “workhorse” of the US military, and flew 746,000 missions, more than the P-38, P-40 and P-51…combined!
Designed from Day One around a massive TURBO-supercharged Pratt & Whitney R-2800 (2,800 cubic inches!) air-cooled, radial Double Wasp engine to be the premier high altitude fighter of WWII (except for a very few Fw Ta-152s that barely saw combat.)
It was the best and fastest piston-powered diver of the war with its very rare and expensive electric dive flaps.
It was the 2nd best roller of the war after the Fw 190.
With those diving/rolling skills it was a great air-to-air fighter, master of “Boom and Zoom,” diving. ambush attacks and helped break the back off the Luftwaffe a full year before the P-51s started arriving in significant numbers.
It was always very fast, and then after the ultra-fast P-47 M model came out, it was the fastest piston-powered aircraft of the war (except for a very few rare German experimentals that didn’t see combat)
