A 4 year refurb. according to the Wiki ... I can only assume this was constrained by finances, as I'm surprised to see the missile armament (ssn19 shipwrecks?) was not replaced with something more compact and enabling a greater load out.
Does anyone have any details as to the refurbishment activities carried out? ie was it purely a refurb - addressing wear and tear? or were any upgrade activities undertaken?
What with?
Bte, these launchers aren't for SS-N-19.
