Its a purely mechanical test.


According to the article and people in the know, it did require some computing and software tweaking to make it happen...guess you were wrong. :roll:


Yes "some" not being "MASSIVE"

Meant to write fairly, said purely instead. My mistake :bang:

Sure the 30mm round from Avenger Gatling Gun is larger than the 25mm round used by the GAU-22/A in the F-35. Yet, do you have any proof the former has a heavier punch than the latter??? :roll:


I was being sarcastic :D

The APEX round might punch above it's weight and be more versatile than conventional types of ammunition, but the difference in mass, especially against depleted uranium rounds, is just too significant.


I don't know if the A-10's GAU-8 still uses DU rounds. I don't even know if DU rounds are still in use because of all the bad press along with physiological and environmental effects the Depleted Uranium is said to cause.

If both were your typical ball rounds... yes the 30mm from the GAU-8 would have more kinetic power over the 25mm from the GAU/22A

either way the 25mm APEX should give anyone a real bad day.

One is designed to kill Soviet Tanks in the Fulda Gap, the other isn't :mrgreen:

AF-2, a highly modified flight sciences aircraft, underwent four months of instrumentation modifications and had a line production gun installed for this project.

Tiffany Krogstad, Lockheed Martin AF-2 flight test engineer, said that the AF-2 is normally a "scientist aircraft" executing loads and buffet testing.

"[AF-2] is the only aircraft in the world that can get us this data," said Rollins. "It's been highly instrumented in order to get us the information we need to proceed to the next test point and ultimately to get the gun to its full envelope."

As the test conductor, Krogstad and her team are monitoring the gun's performance and ensuring all the systems work as designed. She is especially concerned with making sure the jet can withstand the loads of a firing gun and the gun operates as expected. Since AF-2 is a flight sciences aircraft, it does not have all the missionized systems of full-line
production aircraft. The gun will be further tested with a line production jet sometime next year for full integration.

Wait a sec> is this the same AF-2 that david Axe is saying cant dog fight? This plane is a flight scienes plane!
Why would you spin a load testing plane, as IOC rep?

If we did that we wouldn't have as many articles and terrible bloggers to make fun of and tear there arguments apart with logic and information.

Can we add Foxtrotalpha to that list? Solomon is okay since he delivers so many laughs.

F-35A Fires 25mm Gun at Full Capacity
20 Aug 2015 Edwards AFB

"An F-35A fired 181 rounds from its four-barrel, 25 mm Gatling gun during a ground test at Edwards Air Force Base, California, earlier this month....

...The first phase of F-35 gun testing started June 9, when initial shots were fired from the ground at the base’s gun harmonizing range. Over the next few months, the amount of munitions fired gradually increased until the 181 rounds were fired August 14. To conduct the testing, an F-35 flight sciences aircraft, AF-2, underwent instrumentation modifications and used a production version of the GAU-22/A gun. The ground tests were designed using software to replicate being in flight and the aircraft used a target practice round, PGU-23/U, which does not explode on impact.

In integrating a weapon into the stealthy F-35 aircraft, the gun must be kept hidden behind closed doors, reducing its radar cross section, until the trigger is engaged. The tests certify the gun’s ability to spin up and down correctly. The GAU-22/A system will be further tested with a line production F-35A next year for integration with the jet’s full avionics and mission systems capabilities. Test pilots will then observe qualitative effects, such as muzzle flash, human factors, and flying qualities. The F-35 test team will also monitor the GAU-22/A's performance and ensure all systems work as designed, validating that the aircraft can withstand the loads of a firing the gun, mitigating potential effects including vibrations, acoustics and airflow."

F-35A Gun Fires 181 Rounds
Published on Aug 20, 2015 LockheedMartinVideos

"The video clip shows the 181-round gun burst of the gun embedded in the F-35A's left wing root. The gun will provide operational F-35A pilots an ability to engage air-to-ground or air-to-air weapon targets using its strafing capability in addition to its beyond-visual-range air-to-air missiles and precision-guided air-to-ground weapons"

Well, the little door below the gun is definitely a gun gas scavange door, it's oriented to collect air. The big gray patch towards the rear of the gun compartment panel (where the exhaust hose is connect to in the last portion of the video) is some sort of vent. I reviewed some F-35A photo collections and it's a grill/mesh of some sort bordered by No Step warnings.

That "rear mesh vent" must be what that "red hose" is attached to which is likely under vacuum.

The gun port flips open quite quickly and firing commences immedately thereater. So far the naysayers haven't brought up a criticism from the F-22 days ie. the gun will fare poorly in "snap shot" engagements. But give them time....
