I was thinking more along the lines of US ships and Soviet ships in other country's navies that could be brought back to their respective navies but that is a good point.

And we know that both countries have been doing that - from the way Satellite Down is written it and also A Rock In Troubled Waters it is clear that both navies have been bringing older ships into play

i.e. the Forrest Sherman DD's mentioned in both modules are an example

and you have the Soviet destroyer Maskov mentioned as below in Satellite Down - and by the way I cant find any such named destroyer so it must be standing in for a real destroyer - from the description - i.e. all gun with a forward five inch turret it either had to be a Skoryy or a Kotlin class DD

Then the Soviet ship Maskov arrived in the area, and their attitude toward Brupp and the crew changed.

The Maskov was nothing more than a battered hulk of a
destroyer, brought out of mothballs in the last few months of
1998. Low on fuel and looking for a quick kill, the captain of
the ship learned of an American vessel supposedly operating
in the Gulf. These rumors helped him find the USS Virginia off
San Jose. On 4 May 1999, the Soviet vessel spotted the remains
of the Virginia in the distance. Thinking the ship was functional
and operational, it sped directly toward the scuttled ship,
firing wildly and almost blindly.

Brupp had managed to keep most of his ship's systems functioning.
The five-inch guns of the forward turret bore in on the
approaching Soviet vessel and cut it to shreds. The missiles that
the Maskov fired fell just short of their target, while the guns
of the beached Virginia fired on. Within a matter of minutes,
the aged Soviet destroyer blew apart, going down with all hands
