ARLINGTON-<\/strong> The Pentagon has awarded Pratt & Whitney<\/a> a $6.6 billion contract to supply F135 engines for upcoming F-35<\/a> Joint Strike Fighter program production batches.<\/p>\n\n\n\n

The agreement finalizes earlier negotiations and supports both Lot 18 and Lot 19 aircraft deliveries.<\/p>\n\n\n\n

The deal includes engines, spare modules, and support equipment, ensuring continued propulsion capability for the F-35 fleet.<\/p>\n\n\n\n

It also reflects sustained investment in production capacity and future upgrades to meet evolving operational demands.<\/p>\n\n\n\n

US Awards F-35 Engine Contract to P&W<\/h2>\n\n\n\n

The finalized contract covers two major production lots. Lot 18 includes approximately 140 production engines and is scheduled to begin deliveries this fall.<\/p>\n\n\n\n

Lot 19 includes around 150 engines<\/strong>, with deliveries expected to start next year. Combined, these batches support nearly 296 aircraft planned by Lockheed Martin<\/a>.<\/p>\n\n\n\n

The F135 engine remains the core propulsion system across all F-35 variants. It delivers high thrust, operational reliability, and mission readiness for the United States and allied forces.<\/p>\n\n\n\n

According to Breaking Defense<\/a>, this contract reflects sustained global demand and the need to scale production efficiently.<\/p>\n\n\n\n

The agreement also formalizes a previously issued undefinitized contract valued at nearly $2.9 billion for 141 engines under Lot 18.<\/p>\n\n\n\n

This structure allowed production to begin while final pricing and quantities were negotiated. The finalized contract now defines full terms and extends work through March 2028.<\/p>\n\n\n\n

A senior executive from Pratt & Whitney emphasized that the F135 engine continues to set benchmarks in performance and reliability, while ongoing investments in the supply chain aim to accelerate production and meet increasing demand.<\/p>\n\n\n\n
