The U.S. Air Force is signaling that patience is running thin with the jet engine manufacturers responsible for powering America’s fighter fleet, and for good reason.
When the nation is staring down China, Russia, Iran and every other bad actor watching for weakness, unreliable engine production is not some paperwork nuisance.
The service is now looking for new engines, and possibly new manufacturers, after laying out a blunt assessment in a new Request for Information.
The deadline for industry responses is Aug. 28.

“The current industrial base has demonstrated significant challenges, including production delays, quality control issues, and critical obsolescence (i.e., diminishing manufacturing sources and material shortages) across key engine components,” the Air Force warned in the RFI.
That is government speak for a very real problem. The people getting paid to deliver world class engines for American warplanes are not delivering at the level the mission demands.
“The government will pursue a strategic competition requiring industry to innovate manufacturing and guarantee supply chain resiliency,” the RFI said.
The days of comfortable legacy contracts and shrugging through delays may be getting a little less comfortable.

The move comes as the Air Force continues to wrestle with engine problems across major aircraft programs.
The F-35 program has already suffered delivery and upgrade delays tied to engine issues, which is exactly the kind of thing America cannot afford while adversaries are rapidly modernizing their own forces.
A Government Accountability Office report noted last year that “the engine contractor is still not delivering engines to contract specifications after 20 years of production.” Twenty years is not a rough startup period, it is a career.
The B 52 modernization effort has also been slowed in part by engine troubles. According to the GAO, those issues helped drive costs up by $3 billion and pushed initial operational capability back by 15 months.
Now the Air Force is preparing a multiyear fighter engine procurement effort that could require more than 180 engines per year by 2034. The RFI specifically points to engines for the F-15EX and F-16, two aircraft lines that remain central to American and allied airpower.
The Air Force says the new approach will be built around “five foundational pillars designed to drive a paradigm shift in engine procurement and sustainment.” It also says the government is moving away from “legacy procurement toward incentivizing industry-led technological evolution and capacity expansion.”
One of those pillars is “holding vendors accountable” for delivering engines that are more capable, more reliable and cheaper to maintain. That accountability language is welcome, because taxpayers have seen plenty of programs where the costs rise, the timelines slip and the excuses arrive right on schedule.
The Air Force said it will focus “on the total lifecycle cost of the engine, not just the initial purchase price.” That is a critical shift, because a cheap engine that bleeds money in maintenance and keeps aircraft grounded is not cheap at all.
Contractors will also have to prove they can keep supply chains functioning. “We will implement an acquisition strategy that prioritizes ease of maintenance and establishes a resilient, sustainable supply chain from day one,” the Air Force said.
“This effort is designed to solve key fleet-level issues by requiring a newer engine with improved supportability,” the service added. That means the Air Force wants engines that maintainers can actually keep running without turning every repair into a scavenger hunt for scarce parts.
“The result is a streamlined logistics footprint that reduces downtime, lowers the burden on our maintainers, and ensures the continuous flow of parts and support to maximize flightline readiness.” That line gets to the heart of the issue, because readiness is not a slogan, it is whether jets can fly when commanders need them.
The larger question is whether the American war industrial base can still scale like a superpower. The Air Force says it intends to “enforce stringent producibility requirements.”
“We will select a partner capable of scaling production to meet surge requirements, guaranteeing a steady and uninterrupted supply of engines for USAF/FMS [Foreign Military Sales] aircraft (e.g. F-15EX and F-16) programs,” the RFI reads. That matters not only for U.S. squadrons, but also for allies relying on American airframes.
Companies responding to the RFI must provide details on development and manufacturing timelines. They are also being asked to specify “at what minimum volume your supply chain can justify private capital investments (such as facility expansion, tooling modernization, or advanced automation) and how those investments will structurally lower your long-term unit costs.”
Raw materials are another major concern, especially with China restricting sales of rare earths and nations competing for critical inputs.
“From your company’s market perspective, what are the primary raw material constraints (e.g., specialized titanium/nickel alloys) or manufacturing process bottlenecks (e.g., advanced casting or forging capacity) that pose the highest risk to scaling up fighter engine production?” the RFI asks.
The message is clear enough. The Air Force wants engines that show up on time, meet specifications, survive operational stress and do not leave America’s pilots waiting on a fragile supply chain while Beijing takes notes.
