The main advancement of the S-200V VEGA. V-860PV (5V21V) MISSILE against the earlier version was that it doesn't required CW signal continuously. If CW signal dropped for a short time, it continued flying and looked for the RPC signal to be switched back again... ... and the KUB has more nastier trick also.
Yes, you have to carefully watch KRO signals and don't missile let fly without CW signal for too long (more than 30 or 60s?) But for how long you have to switch RPC back on again? Is this practice mentioned somewhere in the official manual?
