You rang, sir?
Looks like some kind of retro-thrust device to get it clear of the launch aircraft in the shortest possible time, then motor ignites at V=0 and the thrust-vectoring spins it around to acquire and engage the target.
At the time this was heard about, there was speculation that the targeting system was to be installed in the big tail sting of the Su-34.
