    It appears that USSTRATCOM has lost 83127Q / 27468, and judging by its recent
    rate of decay, it may no longer be in orbit.
    
    It is/was very small, which would have made it very difficult to observe. Mike
    McCants reports a median radar cross-section of just 0.16 m^2, derived from 18
    OIG Satellite Situation Reports. 
    
    The evolution of its orbit over the past couple of years reveals very strong
    solar radiation pressure perturbations, which indicates a large ratio of surface
    area relative to mass - probably a thin sheet of thermal blanket. Its mass
    likely would have been tens of grams - not enough to have put on much of a show
    on decay.
