Troubled Lockheed F-35 Risks More Groundings on Lack of Working Engines
A shortage of spare engines may leave some Lockheed F-35 grounded because it's taking longer than planned to repair a key component for the US's costliest warplane, according to congressional auditors.
“Inadequate maintenance depot capacity leading to a shortage of operating” engines has “grounded F-35s more often and for longer time periods than expected,” the Government Accountability Office said in a new report Tuesday.

Engines for the plane that's built by Lockheed Martin Corp. are provided by Raytheon Technologies Corp.'s Pratt & Whitney unit.
So far, 820 F-35s have been delivered worldwide out of a potential 3,000 for the US and partner nations. After years of talks, the Pentagon announced Monday evening that it reached preliminary agreement with Lockheed on the next three-year contract for 375 more of the advanced fighters.
Lockheed said Tuesday that it expects to reach a final agreement on the F-35 contract in the third quarter. The No. 1 US defense contractor cut its earnings forecast and trimmed its near-term F-35 plan, citing impacts from Covid-19 and other factors affecting the program.
Lockheed's shares fell as much as 3.5% early Tuesday before paring the decline amid broader market gains. The stock was down 1.5% at 12:05 p.m. in New York.
The GAO report expands on public testimony the agency gave to a House panel in April. Its warning of the need to stem a current, and possibly expanding, shortage of ready engines contrasts with positive publicity that the F-35 is receiving as it flies patrols over
