    In his WWSL Phillip Clark has for both sats, C2389 and C2398, the following:
    
    Military navigation satellite in the Parus system.
    Satellite is a cylinder, approximately 2 metres diameter and 2.1 metres
    high, plus a long boom for gravity stabilisation.
    Operational lifetime is approximately five years.
    
    Cosmos-3M second stage is a cylinder, 2.4 metres diameter and 4.21 metres
    long (6.59 metres including the
    payload adapter and engine nozzle): two outer pairs of propellant tanks are
    carried, increasing the
    maximum diameter to 3.2 metres.
    
    Perhaps a typo in the McCantsfile?
    
    The size of the rocket of C2407 also differs from what is common for a
    Cosmos-3M 2nd stage.
