• Pratt & Whitney designs manufactures and services large engines for widebody narrowbody and large regional aircraft for commercial customers and for fighter bomber tanker and transport aircraft for military customers. It also designs manufactures and services small engines powering regional airlines general and business aviation and helicopters. The company produces sells and services military and commercial auxiliary power units. Pratt & Whitney provides fleet management services and aftermarket maintenance repair and overhaul services in all of these product segments. Its products and services are sold principally to aircraft manufacturers airlines and other aircraft operators aircraft leasing companies and the U S and foreign governments. Pratt & Whitney produces and services the PW1000G Geared Turbofan engine family. GTF engine models have demonstrated a significant reduction in fuel burn and noise levels and lower environmental emissions compared to prior generation engines. The GTF aftermarket network expanded to 21 facilities worldwide increasing shop visit output for the PW1100GJM model by approximately 26 percent year over year in 2025. The GTF family now powers more than 2600 aircraft for over 90 operators across three aircraft platforms Airbus A320neo family Airbus A220 and Embraer E Jets E2. In 2025 the GTF Advantage engine received FAA and European Union Safety Agency certification for the Airbus A320 neo family and is expected to extend the benefits of the current GTF engine increasing takeoff thrust by 4 to 8 percent and reducing fuel consumption by up to an additional 1 percent maintaining the engine’s lead as the most efficient powerplant for the A320neo family. Pratt & Whitney produces and sustains the F135 engine for the U S government’s F 35 Joint Program Office to exclusively power the single engine F 35 Lightning II fifth aircraft produced by Lockheed Martin. F135 propulsion system configurations are used for the U S Air Force’s F 35A the U S Marine Corps’ F 35B and the U S Navy’s F 35C jets. F135 engines are also used on all F 35 aircraft purchased by Joint Strike Fighter partner countries and other countries through foreign military sales arrangements. In 2025 Pratt & Whitney’s F135 engine surpassed one million engine flight hours and the company was awarded a 2 8 billion undefinitized contract action for production of Lot 18 and Lot 19 long lead funding for the F135 engines to power all three variants of the F 35 Lightning II aircraft. Additionally Pratt & Whitney continued design maturation and aircraft integration efforts for the F135 Engine Core Upgrade. Significant activity continued on Pratt & Whitney’s military engine development programs including the Next Generation Adaptive Propulsion program. In early 2025 Pratt & Whitney completed the Detailed Design Review of its XA103 engine for the U S Air Force’s Next Generation Adaptive Propulsion allowing it to begin procurement of hardware for the construction of the prototype ground demonstrator. Meanwhile the B 21 Raider which is powered by Pratt & Whitney engines continued to progress its flight test program. In 2025 Pratt & Whitney Canada was selected by the European Union's Clean Aviation to lead the PHARES project marking the first time a Canadian company will participate in and lead a Clean Aviation program. As part of the PHARES consortium Pratt & Whitney Canada will collaborate with Collins ATR Airbus and technology research organizations to design and integrate a hybrid electric propulsion demonstrator targeting up to 20 percent improved fuel efficiency on regional aircraft missions. Finally in 2025 Pratt & Whitney Canada’s PT6 engine family surpassed 500 000 engine flight hours since entering service.
