Cost of Sustaining Lockheed’s F-35 Jet Now Forecast to Exceed $1.5 Trillion

(Bloomberg) — The world’s costliest weapons program, Lockheed Martin Corp.’s F-35 fighter jet, is getting even more expensive, according to a government watchdog.

Nine years after the Marine Corps declared its first F-35s operational, the Pentagon now projects that the cost of operating and maintaining the jet through 2088 will be $1.58 trillion, 44% higher than originally forecast in 2018, the Government Accountability Office said Monday in a new assessment.

It’s another troubling sign for the F-35, which is billed as the stealthiest and most advanced fighter jet ever and sits at the center of US war planning. Despite its high price tag and maintenance issues, the US and several allied governments — including Israel — already fly hundreds of F-35’s, and it played an important role in helping repel a barrage of Iranian missiles and drones aimed at Israel over the weekend.

The GAO report paints a troubling picture of the plane’s readiness, saying that inadequate training, a lack of spare parts and support equipment and a heavy reliance on contractors mean all three services that deploy the jet — the Air Force, Marines and Navy — project they will be able to fly the F-35 less often than originally hoped.

“The F-35 fleet’s overall availability has trended downward considerably over the past five years, and none of the variants are meeting availability goals — the percentage of time the aircraft can perform one of its tasked missions,” according to the assessment. “The F-35 fleet is not meeting most of its performance goals.”

Pentagon officials told auditors that “significant F-35 program cost reductions will only come from flying the aircraft less or reducing the number of aircraft in the fleet.”

The Pentagon’s progress to improve readiness will be probed Tuesday afternoon during a hearing by a House Armed Services subcommittee. The Pentagon’s program office in March 2023 when confronted with an overall readiness rate of 54% convened a “War on Readiness” to increase the overall rate by 10% by last month.

The Pentagon last month declared the F-35 ready for full-rate production,  a largely symbolic decision because Lockheed already is assembling the jets. The US now has on contract 881 of its planned 2,456 planes. The decision was delayed years beyond its most recent goal of April 2019, but the announcement may give some assurance to the nations committed to spending billions of dollars on the jet.

The new assessment indicates that the military has been trying for years, with little success, to make the F-35 less expensive to fly by squeezing efficiencies and reducing costs for spare parts and repair facilities.

One major driver of maintenance costs is the Pentagon’s heavy reliance on Lockheed for support, the GAO said. The sustaining support cost element, which captures most sustainment costs associated with the contractor, is a large portion of the F-35. The Pentagon “is seeking expanded government control over the program to reduce program costs and improve program performance,” it said.

As of December, all three services that use the jet were falling well short of their performance goals. Just 52% of the Air Force’s F-35A’s were considered partially mission-capable, short of a goal of 80%. For the Navy, that number was 62% compared to a goal of 75%, and the Marines reported similar numbers.
