I don't think that there is much logic to most of the AHL ships. There are some groups of related ship names, but that's about it.
Coming up with 50+ related ship names without devolving into silliness (Bob Lightning, Alpha Lightning, Bravo Lightning, etc) can be pretty tough unless you are working with names (drawn from people who have won the Starburst for Extreme Heroism, for example).
Not too different than some current ship naming schemes. The Nimitz class carriers seem to be named for an admiral, presidents, and 2 congressmen nice to the navy.
