Vought F4U Corsair

The F4U Corsair was a low wing monoplane fighter developed by the Chance Vought Corporation in WWII.  Similar to other aircraft built at the time, due to the need to produce a large number of aircraft to meet wartime demands the F4U design was licensed out to both Brewster Aeronautical and Goodyear, designated the F3A and FG, respectively.  Per Reference [8] first flight for the Corsair was on 29 May 1940 wih the type entering service on 28 December 1942.  A total of 12,571 of all variants were produced.

The Corsair had a distinctive inverted gull wing and razorback profile, though a later post variant designated the F2G was developed configured with a bubble canopy, though only a very limited number were produced. In addition the main landing gear would be rotated 90 degrees to allow them to fit within covered wells in the wings when retracted.  The Corsair along with the Grumman F6F Hellcat would serve as the primary fighters of the US Navy and US Marine Corps during the second half of the war in the Pacific.  It would also serve with the UK and New Zealand during the war, as well as France, Honduras, El Salvador, and Argentina post WWII.

The primary variants analyzed at this website include:

• the F4U-1
• the F4U-1D
• the F4U-4

Per Reference [8] the F4U-1 was the initial production variant of ths Corsair family and had a Birdcage type framed canopy and a lower seating position than later variants.  This variant was also called the Corsair Mk I in Royal Navy service.  The F4U-1D was fitted with an upgraded engine with water injection, and also had a revised "blown" single piece canopy.  In Royal Navy service it was designated the Corsair Mk II.  The F4U-4 was the last variant to see active service during WWII.   It was fitted with a four bladed propeller and an improved engine capable of producing more power.  

As shown in the images below distinguishing features of this aircraft including;

• a large radial engine 
  
• a razorback configuration aft the cockpit
• a framed "birdcage" type canopy on the F4U-1
• a "blown" single piece canopy on the F4U-1D and F4U-4
  
• low mounted inverted gull folding wings
  
• main landing gear that rotated 90 degrees to retract into covered wells in the wings
