The General Electric/Allison J33 was a development of the [Vous devez être inscrit et connecté pour voir ce lien], enlarged to produce significantly greater thrust, starting at 4,000 lbf (18 kN) and ending at 4,600 lbf (20 kN) with an additional low-altitude boost to 5,400 lbf (24,000 N) with water-alcohol injection.
Development
The J33 was originally developed by [Vous devez être inscrit et connecté pour voir ce lien] as a follow-on to their work with Whittle's designs during [Vous devez être inscrit et connecté pour voir ce lien].
Their first engine was known as the I-A, but after major changes to adapt it to US production and to increase thrust, it started limited production as the I-16 in 1942, the 16 referring to its 1,600 lbf (7,100 N) thrust.
Full production started as the [Vous devez être inscrit et connecté pour voir ce lien] when the [Vous devez être inscrit et connecté pour voir ce lien] introduced common naming for all their engine projects.

Along with the I-16, GE also started work on an enlarged version, known as the I-40. As the name implied, the engine was designed to provide 4,000 lbf (18 kN).
The development cycle was remarkably rapid.
Design work started in mid-1943 and the first prototype underwent static testing on January 13, 1944.
[Vous devez être inscrit et connecté pour voir ce lien] was in the midst of the [Vous devez être inscrit et connecté pour voir ce lien] project at the time, originally intending to power their design with a US-produced version of the [Vous devez être inscrit et connecté pour voir ce lien] of about 3,000 lbf (13 kN).
Production of the H-1 ran into delays, and since the I-40 would dramatically improve performance, plans were made
to fit the prototypes with the I-40 instead.
The I-40 became important to the USAAF's plans when the I-16 powered [Vous devez être inscrit et connecté pour voir ce lien] was skipped over in favor of the I-40 powered P-80 as the US's first production jet fighter.
In 1945 the license to actually produce the engine was not given to General Electric, but Allison instead.
Allison, working largely from government-owned wartime factories, could produce the engine in quantity more quickly and cheaply.
By the time the production lines were shut down Allison had built over 6,600 J33's, and General Electric another 300 (mostly the early runs).
