A Marine Corps F-35B Crashed at MCAS Miramar and the Pilot Ejected Safely

A Marine Corps F-35B crashed at Marine Corps Air Station Miramar in San Diego on the morning of Friday, July 31, 2026. The pilot ejected, was recovered at the scene, and reached a local hospital in stable condition with injuries described as not life threatening.

The jet went down at around 10 a.m. Pacific time. The Associated Press reported that the aircraft crashed while landing, and the impact started a small fire in open ground beside the airfield that crews doused with water and retardant.

In a statement provided to Task & Purpose, the Marine Corps said it could confirm “a Class A mishap involving a Marine Corps F-35B in the vicinity of [Marine Corps Air Station] Miramar,” and that “the pilot ejected and has been recovered.” The aircraft was assigned to Marine Aircraft Group 11, part of the 3rd Marine Aircraft Wing based at Miramar.

The pilot was the only person on board. No injuries on the ground have been reported, and the Marine Corps has not announced a cause.

What a Class A mishap actually means

Class A is the most serious of the military’s mishap categories. Marine Corps spokesman Capt. Steven Keenan used the term in comments to NBC 7 San Diego, and it applies when a mishap kills or permanently disables someone, destroys a Department of Defense aircraft, or causes at least $2.5 million in damage.

That threshold is trivially easy to cross with this airframe. A single F-35B costs roughly $109 million, so nearly any crash involving one is a Class A event by definition, whatever the eventual cause turns out to be.

The classification is bookkeeping, not a finding. It records how serious and how expensive the outcome was, and says nothing about what went wrong or who was responsible.

Two separate reviews normally follow a mishap this severe. Under standard Navy and Marine Corps practice, a safety investigation works quickly and under privilege, so that the people involved can speak candidly without their words becoming evidence, while a parallel command investigation builds the record that can eventually be released.

That is why the official cause of a military crash often stays unpublished for a year or more. The first public account usually arrives long after the news cycle has moved on.

Why landing is the F-35B’s most demanding moment

The B is the short takeoff and vertical landing version of the F-35 Lightning II, built specifically so Marine Corps fighters can operate from amphibious assault ships and short expeditionary strips rather than full-length runways.

It buys that ability with a Rolls-Royce lift fan mounted behind the cockpit and driven by a shaft off the main engine. In a hover, the fan supplies around 20,000 pounds of vertical thrust while the main exhaust nozzle swivels downward.

All that machinery makes the transition to landing the most mechanically complex part of an F-35B flight. Lockheed Martin and seat maker Martin-Baker accounted for it in an unusual way, and the result is a feature no other fifth-generation fighter carries.

Whether the jet was in that flight regime on Friday has not been stated, and no official has suggested the automatic system was involved. It is context for how the aircraft is built, not an explanation of this crash.

A crowded year for stateside military mishaps

The Miramar crash lands in a busy stretch for the services at home. As Military.com noted, it follows a Navy Growler collision in May, a Marine F/A-18 crash in Washington state in June, and an Air Force B-52 crash at Edwards Air Force Base the same month.

Marine aviation is also mid-transition on several fronts, having recently taken delivery of its last MV-22B Osprey as production wound down. Fleet turnover and a heavy training tempo tend to show up together in mishap statistics, though no one has linked either to Friday’s events.
