I understand the Royal Air Force doesn't intend to use the cannon designed for the Eurofighter Typhoon, but I've yet to see a photo of one of these airplanes in service with any of the other countries employing it where the cannon appears to be installed. I know the cannon is found on the right side of the airplane, adjacent to the fuselage and the barrel extends into a fairing on the right wing leading edge. There's no opening in any of the fairings I've seen, which leads me to believe the cannon isn't installed or the opening is covered to prevent FOD to the cannon barrel.
Can someone shed some light on what's going on here? I understand the Typhoon has passed the tests associated with the cannon and it's cleared for service with the user air forces.
