Norwegian / Finnish aerospace and defence group Nordic Ammunition Company (Nammo) has concluded the maiden live fire trials of the GAU-22 Gatling gun.
Developed specifically for the F-35 Lightning II, the four-barrelled GAU-22 gun was fired at Nammo’s purpose-built facility in Raufoss, Norway.
The gun is currently the only weapon of its kind being used outside the US.
Nammo Aircraft Ammunition programme director Anders Nyhus said: “This setup is really unique, in that allows us to do all the testing we need just minutes away from the production site.
“That again means that can cut down the time between a production lot leaving the factory, and when it is tested and ready to go to the customer. It also means we can have a much higher confidence in the quality of the products we deliver, as we are able to control every aspect of the process from beginning to end.”
The GAU-22 Gatling gun and its associated facility have been procured through an agreement with the Norwegian Defense Materiel Agency as part of the development of Nammo’s APEX-ammunition for the F-35.
The APEX is the only ammunition type that is available for the F-35 fighter jets and will enable the aircraft to use its gun effectively in any scenario.
Nammo serves as the only ammunition provider for the F-35 aircraft able to carry out a complete range of verification and acceptance testing for every production lot independently.
