Woo, boy. Here’s video showing Lockheed Martin conducting the first aerial test for the F-35’s gatling gun. Called the GAU-22/A, the weapon can pop off 3,300 25mm rounds per minute. The gun fires so fast that your eyes might miss it. Even though the test was successful, the GAU-22/A won’t be combat ready until 2019 because the control software is still being developed.
