In addition, the F-35 has been used by four services to conduct combat operations.

Lockheed Martin F-35 programme vice-president and general manager Greg Ulmer said: “These milestones are a testament to the talent and dedication of the joint government, military and industry teams.

“The F-35 is delivering an unprecedented fifth-generation combat capability to the warfighter at the cost of a fourth-generation legacy aircraft.”

The first F-35A aircraft conducted its maiden flight in December 2006.

The original version of the aircraft was enhanced and flew its first flight in November 2009.

The multi-role, supersonic, stealthy fighter aircraft can perform air defence, ground attack and reconnaissance missions.
