    The longevity of the later KH-11 derived satellites, of which at least Misty-1 and probably Misty-2 are thought to be members, makes the possibility that M-2 might be still up there something to keep in mind.
    
    I suspect that the limiting factor in their lifetime is the ability to maintain strict attitude control, as that's almost certainly crucial for staying stealthy. Once that runs out, I'd expect them to be deorbited.
