By Key Facts
- Aircraft Type: Lockheed Martin F-35B Lightning II
- Operator: US Marine Corps
- Location: Marine Corps Air Station Miramar, San Diego, California
- Date: Friday 31 July, 2026
A Marine Corps F-35B Lightning II stealth fighter crashed at Marine Corps Air Station (MCAS) Miramar in San Diego on Friday, with the pilot ejecting before impact and surviving the incident. Authorities transported the pilot to a local medical facility in stable condition, where he is being evaluated and treated for non-life-threatening injuries.
What Happened to the Marine Corps F-35B at Miramar
The crash occurred at MCAS Miramar, the major Marine Corps air installation on San Diego’s northern edge that serves as home to several F-35B-equipped squadrons. The pilot initiated an ejection sequence before the aircraft went down, a decision that proved critical to his survival.
No further details on the cause of the incident or the extent of air frame damage have been released. Investigations of this kind are typically conducted jointly by the relevant branch’s aviation safety command and, where warranted, the Naval Safety Command.
About the F-35B Lightning II
The F-35B is the short takeoff and vertical landing (STOVL) variant of Lockheed Martin’s fifth-generation Lightning II family, designed specifically for Marine Corps operations from expeditionary airfields and amphibious assault ships. It differs from the conventional F-35A and the carrier-based F-35C through its lift-fan propulsion system, which enables vertical landings.
The US Marine Corps declared initial operational capability on the F-35B in July 2015, making it the first service worldwide to field the type operationally. Because the aircraft carries a Martin-Baker US16E ejection seat, crew escape systems are well-proven — however, ejections at low altitude or low airspeed carry inherent risk regardless of seat performance.
MCAS Miramar has hosted F-35B units since the Marine Corps began transitioning its legacy Harrier and F/A-18 fleets, and Friday’s crash is among the more visible incidents at the installation in recent years. The base is located within the San Diego metropolitan area, meaning incidents there draw immediate public and media attention.
The Marine Corps had not released the pilot’s name or unit as of the time of reporting. An official investigation is expected to follow standard aviation mishap procedures, with preliminary findings typically released within weeks and a full report potentially taking considerably longer.
