Pratt & Whitney, a Raytheon Applied sciences enterprise, has gained a $115 million contract for the F135 engine enhancement effort, additionally known as an engine core improve. The contract award will help Pratt & Whitney’s preliminary improvement actions by way of 2023. The F135 engine core improve delivers the quickest, most value environment friendly, lowest danger path to Block 4 functionality for all international F-35 operators. It’s the solely F-35 propulsion possibility that could be a ‘drop in’ resolution for all variants, including no weight and avoiding disruptive and dear air car adjustments that may introduce further prices, schedule delays, and technical danger. The F135 program is a serious driver of financial development within the state of Connecticut and across the nation, supporting greater than 53,000 jobs throughout 36 states. In Connecticut alone, this system helps greater than 27,000 direct and oblique jobs and practically 100 suppliers.

“Pratt & Whitney is among the foremost leaders in superior know-how and protection manufacturing. The latest announcement will defend good paying union jobs in Connecticut, whereas offering a much-needed cost to our financial system. Pratt & Whitney employs greater than 11,000 folks in East Hartford and Middletown and is a core element of our state’s financial system,” mentioned Rosa DeLauro, chair of the Home Appropriations Committee.


“Upgrades like this are a standard a part of any main protection program and the F135 engine has been pushed past its unique specs for too lengthy. The F-35 engine core improve saves taxpayers $40 billion in lifecycle prices and builds upon a combat-tested engine structure that has multiple million flight hours. We deeply recognize Chairwoman DeLauro’s help on this important program,” mentioned Jill Albertelli, president of Pratt & Whitney’s Army Engines enterprise.

The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter. It has two variants; a Typical Take-Off and Touchdown (CTOL) variant used within the F-35A and F-35C, and a two-cycle Quick Take-Off Vertical Touchdown (STOVL) variant used within the F-35B that features a ahead raise fan. The primary manufacturing engines had been delivered in 2009. Developed from the Pratt & Whitney F119 engine used on the F-22 Raptor, the F135 produces round 43,000 lbf (191 kN) of thrust. The F135 competed with the Normal Electrical/Rolls-Royce F136 to energy the F-35. Derived from the F119 engine, the F135 is a mixed-flow afterburning turbofan with a brand new fan and LP turbine. There are two F135 variants: the -100 and the -600 variations. A -400 model is talked about, just like the -100, the principle distinction being using salt-corrosion resistant supplies. The -600 is described under with an evidence of the engine configuration adjustments that happen for hovering. The engine and Rolls-Royce LiftSystem make up the Built-in Carry Fan Propulsion System (ILFPS).
