What is interesting is that the crew needed to be rescued by a nearby Turkish ship. who responded to a very late SOS.
Where were all the other naval vessels accompanying the ship?, did they all back off out of range and leave their mates to whomever would pick them up?. One would not normally allow survivors to be taken off by a commercial vessel unless they were the only ones around..
It has been done before by many Navies, so I expect the Moskva was on it's own and may have later been towed South to deeper ocean for reasons that were not related to rescue.(At least two nukes up the spout.)
