- Summary
- To more quickly enter post-World War II jet engine production, Pratt & Whitney licensed production of the Rolls-Royce Nene engine in 1947. Converted to American standards, the resulting J42 Turbo-Wasp was first delivered to the U.S. Navy in late-1948 for installation in the Grumman F9F-2 Panther.
- Realizing the need for a higher-powered engine, Rolls-Royce and Pratt & Whitney Aircraft worked together on a centrifugal-flow turbojet engine with a 30 percent power increase and no significant increase in overall engine size. Introduced in early-1950, the resulting Rolls-Royce Tay and Pratt & Whitney J48 Turbo-Wasp was then the most powerful engine flying in either country. Pratt & Whitney added water injection and an afterburner of its own design which provided substantial power increases for short periods during combat.
- The J48-P-8C powered the Grumman F9F-6 Cougar. Other models powered the Navy Grumman F9F-5 Panther, and Air Force North American F-93A and Lockheed F-94C Starfire.
