When did Los Angeles-class FLT I boats receive anechoic coating?
Does anybody know when the boats started to receive this upgrade?
AFAIK, flight II boats got it from the start, and FLT I boats were modified later - but when exactly?
Also, I'd be happy about *any* source (online) about everything US submarines of the cold war era - besides the obvious Wikipedia stuff.
Blogs, Podcasts, I don't care.
