Pratt & Whitney, a business unit of RTX (NYSE: RTX), has been awarded a nearly $1.3 billion undefinitized contract covering F135 engine spare parts.
The contract is structured as an Indefinite Delivery, Indefinite Quantity agreement, commonly referred to as an IDIQ, providing flexible funding for a range of operational needs.
Funding from the deal will support fiscal year 2026 F135 initial spare parts requirements, deployable spare packages, depot lay-ins, and associated support equipment.
The contract covers both U.S. and international F-35 customers, extending Pratt & Whitney’s global reach into allied defense networks across multiple continents.
The F135 engine powers all three variants of the F-35 Lightning II, which is widely recognized as the world’s most advanced fighter aircraft currently in operational service.
Chris Johnson, vice president of Pratt & Whitney’s F135 Program, emphasized the operational importance of the award for the broader F-35 enterprise.
“Ensuring the F135 remains mission-ready is critical to the success of the F-35 enterprise,” Johnson said, adding that the contract will strengthen the global sustainment network for operators worldwide.
“This contract will help strengthen our global sustainment network to ensure operators around the world can continue to rely on the F135’s unmatched performance,” Johnson said.
The F135 sustainment enterprise currently maintains a global network supporting 42 bases and 13 ships worldwide, alongside multiple dedicated depot facilities.
Pratt & Whitney has delivered more than 1,500 F135 production engines to a customer base spanning 20 allied nations since the program’s inception.
The company is also advancing the F135 Engine Core Upgrade, the selected propulsion modernization solution for the F-35, which will leverage the existing sustainment network.
That upgrade is designed to enhance fleet readiness and deliver cost-effective, long-term capability improvements for global F-35 operators for decades to come.
RTX, headquartered in Arlington, Virginia, employs more than 180,000 people globally and reported 2025 sales of more than $88 billion across its defense and aviation businesses.
