The U.S. military has now confirmed the acceptance of at least six F-35 Joint Strike Fighters for the U.S. Marine Corps without radars. This is due to issues tied to the development of the new AN/APG-85 radar, the first production lot of which is scheduled to be delivered in 2028. The prospect of radarless F-35s had first emerged publicly back in February. The AN/APG-85 is a critical component of the larger Block 4 upgrade package for all variants of the F-35, an effort that has been mired in cost growth and delays.
Marine Corps Lt. Gen. Gregory Masiello, head of the F-35 Joint Program Office (JPO), disclosed the acceptance of the six radarless F-35Bs at a hearing before members of the Senate Armed Services Committee earlier this week. This came as part of a larger back-and-forth between Masiello and Senator Mark Kelly, an Arizona Democrat and a retired naval aviator, about F-35 readiness rates across the U.S. Air Force, Marine Corps, and Navy, which have long been a point of concern.
Two weeks ago, the Government Accountability Office (GAO), a Congressional watchdog, released a report stating that the average F-35 full mission capable (FMC) rate across all variants had fallen from 38 to 25 percent between Fiscal Years 2020 and 2025. GAO defines FMC as an aircraft “that can perform all of its missions.” The F-35 JPO has not disputed GAO’s figures directly, but has openly disagreed with the methodology it uses to determine FMC.
