    originally were in similar orbits, but subsequently manoeuvred so that
    their ground tracks repeat every 2 days, after 11 orbits.
    
    Very interesting indeed, not to say an impressive demonstration of
    observational and analytical skill.
         
    I would suspect that the orbital characteristics of these objects are
    driven by the operational requirements of the COBRA BRASS infrared
    sensors they carry -- perhaps further analysis of that possibility
    would be worthwhile.
         
    Speaking of COBRA BRASS, one of them, CB-E, seems to have been
    installed on USA 137 (98005A) -- are orbital elements available for it?
     Also, there is mention of a subsequent one, CB-F, that was in
    development ca. 2000, but it's unclear if it was ever launched.
