India is working on the idea but having a working system is far away for even the USAF - too many variables involved that require a lot of processing power and sensors/comms to work and sync up.You know what could make all this easier? UCAVs networked to a manned fighter (or AEW&C) with its own BVRAAMs. I believe they call it "air teaming" or "loyal wingman." It'd really suck if India was working on it and we didn't show anything for it, amirite... (ok to be fair, I think -- like BVR in the 1990s -- the PAF wants it, but like the SD-10/AMRAAM, it'll probably be an imported stack from China or Turkey).
To the earlier point, a flying magazine concept is great if it is capable of outranging the enemy - a flying magazine of R-77’s is pretty useless against a fighter with just two AIM-120s. 8 R-77’s are then just 2000 extra pounds of missile and pylons adding on the need to dodge an incoming missile.
