P47-D THUNDERBOLT

P47-D

Story

The Republic P-47 Thunderbolt was one of the most important fighters of the USAAF during the Second World War. Its large size and its secure construction gave it its nickname "Jugg" and made it excel in the fire support of the surface troops. That became quickly its lead role because that just correct performances as fighter didn't allow it to vie with the P-51 Mustang.
This plane originates from two Georgian immigrant labours : Alexander Procofieff of Severky and Alexander Kartveli. Afterwards their immigration to vanish communism they implicated themselves in the American and French aviation development. In the year 1931 they constitute together the Seversky Aircaft Corporation and create a fighter for USAAC : the p-35. 136 exemplars of it are delivered. The plane performances are however disappointing and many projects began trying to enhance them.
The AP-4 demonstrating exemplary with its turbo-compressor motor was the base for a new plane : the Republic P43 Lancer. The company had changed its name because of a shake-up after financial problems.
272 planes were delivered to USAAC to march 1942 but once again were the performances very disappointing.
Two next projects, the XP-44 Rocket and the XP-47A, rose up but American authorities judged their features too bad compared with the German coeval planes.
Alexander Kartveli drew a widened version of the P-43. he named it XP-47B. the new plane was a real monster as a fighter. Its net weight was up to 4490kg so 65% more than the P-43, but its motor was a 2000 horsepower Pratt and Witney R-2800 Double wasp. It was set up with a turbo-compressor and was armed with eight machine-gun fires.
L'USSAF were charmed and gave up the XP-44 and the XP-47A.
In the year 1941, the 6th of may executes the pilot Lowry P. Brabham its first flight with
the XP-47B. the epitome showed a few minor defects but the plane impressed the authorities.

One of the most made planes of the war, the P-47 is the very epitome of the trusty and powerful plane (its eight machine-gun fires attest it). It could negate any enemy fighter in a few seconds with its terrifying firepower.
Furthermore was it much terrifying for the surface troops, specially for tanks.
The P-47 was the biggest and heaviest single-seat fighter of the allied during the second World War. More than 15700 exemplars went out American factories.
