The gun is fitted to every Typhoon, it is fully cleared for use in all configurations (albeit with a caution for 1 weapon station load due to vibration). In RAF service it is fully loaded on every aircraft prepared for ops or QRA.
There are lots of articles out there recording the successful clearance process when the gun came into service. Sadly the ripple caused by the consideration of not funding the gun (it never actually happened) has endured.
