You know a system that is that fast and mobile is going to be dragged into the hot zone sooner or later, just as the humvee has had to be up-armored. If, during WW I, machine guns could be synchronized to fire through the prop (and imagine how scary that must have been for the test pilot to pull the trigger on that system back then), the geniuses we have now ought to be able to design a killer defensive system that won't shoot the rotors off the Osprey.
The geniuses at BAE Systems did design a system that ties into the flight control system, so it can map “no shoot” areas based on the positioning of the nacelles.
The Guardian system was designed by BAE Systems to be a remotely controlled gun for vehicles. They simply mount it ‘upside down’ for use in the Osprey’s two hell holes. They entire system is designed to be easily removed for sling load duty.
This is an ‘interim solution’ to replace the cancelled chin mounted gun system. Methinks it will become permanent on all of the USAF SOCOM CV-22Bs, and eventually on maybe half of the Marine Corps MV-22Bs.
The Remote Guardian system will be in addition to the ramp mounted gun. Of course, the one drawback of the Remote Guardian is that it must be retracted back into the aircraft during landing.
