Well the ranks on the people make sense now.
But like real life the ship classification is always a pain to get right. In this latest edition its now a destroyer like is fellow captured ship that was also a rust bucket.
If learning about ships in our own history has taught me anything, its that people can call a ship 13 different names and classes for whatever reason and they will be correct and wrong. A sloop in one place is a frigate in another and then a different name during peace because of reasons.
So, yes our home ship is now a Destroyer that can go 12x the speed of light in real space or something, has the insides of a luxury liner while having self defense guns and can carry space craft, probably.
While a more normal destroyer is a small, slow, tough, gun boat that can probably only have a ship docked to it.
The Far future maybe just as ridiculous as old history and this fiction is probably more realistic than one might think.
