The engine is getting smarter<\/h2>\n\n\n\n
In February 2025, RTX said Pratt & Whitney had secured a three-year contract valued at up to $1.5 billion to sustain the F119 engines that power the F-22. The company said the deal covers more than 400 engines that had already logged more than 900,000 engine flight hours.<\/p>\n\n\n\n

Pratt & Whitney describes the F119 as the first operational fifth-generation fighter engine, combining stealth technologies, vectored thrust, and a Full-Authority Digital Electronic Control system that regulates engine and aircraft operating parameters.<\/p>\n\n\n\n
That last part is key. A modern fighter engine is not just metal, heat, and fuel; it is also software, sensors, diagnostics, and a constant stream of data about how the aircraft is really being flown.<\/p>\n\n\n\n
Why this has an environmental angle<\/h2>\n\n\n\n
Military jets are not climate-friendly machines, and no one should pretend otherwise. But maintenance choices still carry an environmental footprint, from replacement parts and industrial energy to shipping, testing, and depot work.<\/p>\n\n\n\n
That is where Pratt & Whitney\u2019s Usage-Based Lifing effort comes in. Instead of relying only on historical averages, the system uses real flight data and actual wear patterns to decide when parts need attention, and Air & Space Forces Magazine reported that the company expects nearly $800 million in life-cycle savings from the program.<\/p>\n\n\n\n![\"A](\"https:\/\/okdiario.com\/techy\/en\/wp-content\/uploads\/2026\/07\/f22-raptor-f119-engine-software-sustainment-1.jpg\" "\\"\\"")
By leveraging real-time flight data, the Air Force is shifting toward usage-based maintenance for F119 engines, significantly reducing waste and extending the Raptor\u2019s operational lifespan.<\/figcaption><\/figure>\n\n\n\nEssentially, that means less guesswork. If fewer parts are pulled early and fewer maintenance actions happen before they are truly needed, the result can be a leaner supply chain and less material churn, even if this is still fundamentally a defense readiness program<\/a>.<\/p>\n\n\n\nA bridge to the F-47<\/h2>\n\n\n\n
The bigger picture is Boeing\u2019s F-47. On March 21, 2025, the Department of the Air Force announced that Boeing had won the engineering and manufacturing development contract for the Next Generation Air Dominance platform, which the service described as the world\u2019s first sixth-generation fighter aircraft.<\/p>\n\n\n\n
That sounds like the future arriving all at once. New combat aircraft rarely become mature overnight, however, and the Air Force\u2019s own announcement says the current phase will produce a small number of test aircraft for evaluation before any broader production path.<\/p>\n\n\n\n
So what happens in the meantime? The Raptor has to keep doing the hard work, especially as the Air Force pushes into a period where stealth<\/a>, range, sensors, and software will matter more than ever.<\/p>\n\n\n\nSupercruise still matters<\/h2>\n\n\n\n
The F119 is one reason the F-22 remains such a serious aircraft. Pratt & Whitney says the Raptor\u2019s two engines allow supercruise, meaning supersonic flight without afterburner, which protects mission range instead of burning through fuel at a punishing rate.<\/p>\n\n\n\n
RTX says each F119 generates more than 35,000 lbs. of thrust and helps the aircraft reach altitudes above 65,000 ft. The company also says supercruise conserves fuel and extends operational range, which is still a huge advantage when distance and tanker support<\/a> can shape a mission.<\/p>\n\n\n\n
