“There will be no gun until [the Joint Strike Fighter’s Block] 3F [software], there is no software to support it now or for the next four-ish years,” said one Air Force official affiliated with the F-35 program. “Block 3F is slated for release in 2019, but who knows how much that will slip?”
The tri-service F-35 is crucial to the Pentagon’s plans to modernize America’s tactical fighter fleet. The Defense Department hopes to buy 2,443 of the new stealth jets in three versions—one for the Air Force, one for the Navy, and one for the Marines. Versions of the jet will replace everything from the air arm’s A-10 Warthog ground attack plane and Lockheed F-16 multirole fighter, to the Navy’s Boeing F/A-18 Hornet carrier-based fighter, to the Marines’ Boeing AV-8B Harrier II jump-jet. But the F-35 has been plagued with massive delays and cost overruns—mostly due to design defects and software issues. There have also been problems with the jet’s engine. An F-35 was destroyed on takeoff earlier in the year when a design flaw in its Pratt & Whitney F135 engine sparked a fire.
Another Air Force official familiar with the F-35 confirmed that the jet won’t have the software to fire its gun until the Block 3F software is released to frontline squadrons sometime in 2019. Neither Lockheed nor the F-35 Joint Program Office responded to inquiries about the status of the jet’s gun.
Right now, the F-35’s software doesn’t support the use of the aircraft’s GAU-22/A four-barreled rotary cannon. The weapon was developed from the U.S. Marine Corps’ AV-8B Harrier II jump-jet’s GAU-12/U cannon, but it has one fewer barrel and weighs less.
It’s also supposed to be more accurate—when it can be fired, that is. The gun can shoot 3,300 rounds per minute, though the Air Force’s F-35A version can carry just 180 rounds for the gun.
