The F-35 Lightning II, a Lockheed Martin joint strike fighter, has just completed its first in-flight firing of its 25mm gun.
The flight, piloted by U.S. Air Force Major Charles Trickey, took place on Oct. 30.
The F-35 fired has a four-barrel, 25mm Gatling gun embedded in its left wing and will provide pilots with the ability to strafe air-to-ground or air-to-air targets.
