Pratt & Whitney Wins $1.3 Billion F135 Spares Deal for F-35 Fleet
RTX Corp.'s Pratt and Whitney Military Engines unit received a $1.3 billion contract modification to supply F135 engine spares for the global F-35 program through December 2030, the Defense Department said.
EAST HARTFORD, CONNECTICUT — RTX Corp.‘s Pratt and Whitney Military Engines unit won a $1.3 billion contract modification to supply engine spares for the global F-35 fighter fleet.
The undefinitized action adds scope to an existing indefinite-delivery contract and covers initial spares for the F135 propulsion system, the engine that powers every variant of the Joint Strike Fighter, as announced on war.gov. The award directs depot and common spares into the F-35 global spares pool plus country-unique parts for the Air Force, Marine Corps, Navy, cooperative program partners and Foreign Military Sales customers.
Work will run through December 2030, with no funds obligated at award and money committed on individual orders, the Naval Air Systems Command at Patuxent River, Maryland, said in the notice. East Hartford, Connecticut, carries 59.6% of the effort, followed by Middletown at 16.7% and Windsor at 7.5%, with the balance spread across Maine, Texas, Washington, Rhode Island and California. The Naval Air Systems Command in Patuxent River, Maryland, is the contracting activity, and the modified contract was not competed.
RTX Corporation, the Arlington, Virginia, aerospace and defense conglomerate that reported $88.6 billion in 2025 revenue, ranks among the largest defense manufacturers in the world by sales, according to leanrs.com. The Pratt & Whitney segment supplies engines for commercial, military and business aviation and services military auxiliary power units, according to leanrs.com. The parent adopted the RTX name in July 2023 after operating as Raytheon Technologies Corporation.
The stakes reach well beyond Connecticut. Spares availability determines how many F-35 jets can fly on any given day, so the pool feeds readiness for U.S. services and allied air forces that fly the same airframe. A deeper spares inventory benefits partner nations waiting on parts, while the sole-source structure concentrates that supply chain in a single vendor.
The award ranks as the 6th contract to Pratt and Whitney Military Engines in 2026, lifting the unit’s year-to-date total to $5.5 billion. It stands as the 22nd Defense Department contract awarded in Connecticut this year. The sum trails the unit’s record award of $3.8 billion and sits inside the 2026 Navy portfolio, which ranges from a low near 9 million to a high of $8 billion. It was one of 12 Defense Department contracts issued nationwide on July 30, 2026.
For the average U.S. reader, the deal illustrates how much taxpayer money flows into sustaining a single weapons program long after the aircraft roll off the line. Spares and depot support account for a large share of lifetime F-35 costs, and awards like this signal continued federal spending that anchors thousands of skilled manufacturing jobs across New England.
This has happened before. Pratt & Whitney holds the F135 production and sustainment franchise, and the Navy routinely issues follow-on spares modifications under the same parent contract. Recurring awards reflect the program’s structure, in which a single engine supplier backs a fleet flown by the United States and more than a dozen partner nations.
The Naval Air Systems Command will decide the pace and value of future orders as it issues individual task orders against the contract. A date for the next order has not been announced.
Pratt & Whitney’s roots in wartime propulsion stretch back generations, as happened before. Frederick Rentschler founded the company in Hartford in 1925 and built engines that powered U.S. fighters and bombers through World War II, according to britannica.com. Its radial and later jet engines helped carry American air power across the Pacific and into the jet age. The Connecticut engine maker that armed those campaigns now anchors the propulsion supply chain for the most widely fielded Western fighter of this century.
This contract represents the 6th contract awarded to RTX Corp., Pratt and Whitney Military Engines, in 2026, bringing the company’s total contract value for the year to $5,466,577,387. It is also the 22nd Department of Defense contract awarded in Connecticut during 2026. While this is not the largest contract ever awarded to RTX Corp., Pratt and Whitney Military Engines, whose record stands at $3,813,591,875, it is notable within the Navy portfolio. Specifically, it falls between the 2026 Navy portfolio’s year-to-date minimum of $9,046,496 and maximum of $8,000,000,000. Overall, this award was announced among 12 Department of Defense contracts issued nationwide on July 30, 2026.
