Watch the Marines' F-35 fire an 80-round burst from its gun pod

On July 6, at the Naval Air Station at Patuxent River, Maryland, US Marines carried out the first successful test of the F-35B’s GAU-22 gun pod, Business Insider has confirmed.

Five days later, the gun pod fired it’s first 80-round burst. Both tests were resoundingly successful, and the video is posted below.

Business Insider previously reported on the first test of the F-35A’s integrated gun, but the gun pod, which will be used on the F-35B and C variants, is an entirely different animal.

Instead of the integrated design of the US Air Force’s F-35A, the Marine Corps’ F-35B and the US Navy’s F-35C will feature a 220-round, 25 mm gun in a modular pod.

This means that the Navy and Marine variants, which launch from aircraft carriers or amphibious assault vessels, will have the option of excluding the gun to save weight and increase fuel efficiency.

Here’s the GAU-22 ripping a target with pinpoint accuracy:

While the F-35 has fielded some criticism for its gun, which at 55 rounds per second can empty its entire magazine in under four seconds, the gun actually makes sense for the type of close air-support environment that the F-35 is expected to operate in.

The much-loved A-10 Warthog, which holds 1,350 rounds, is ideal for flying low and slow, loitering in the sky, and delivering its precise fire to provide close air support. But this makes sense in only uncontested air space.

The F-35’s smaller magazine capacity reflects the future of close air support as military planners envision it. The F-35 will usher in an era of quick and precise strikes that leverage a suite of sensors, electronic-warfare capabilities, and stealth.
