Technically, the M-5 also destroyed the Excalibur to Constellation-level damage, since they re-used the stock footage for it. (Another reason why I'm against viewing the AMT kit as a different subclass, but I digress...) Presumably the Exeter was recovered; I believe there's a fan-production based around that. For some reason, memos in TMoST also suggest the Farragut was lost as a result of the Dikironium cloud creature, but I've long suspected that was an error.
But still, I've never liked the idea that all of them were lost except Enterprise, which I believe the TMP novelization opined.
