The names all came from the cadet loading scenes at the Academy. Before we get started on yet another debate like we did the other day about the fate of the ships, the Cadets were all being sent to Vulcan according to the dialogue of the film. When they were boarding shuttles the names of their assigned craft were being told to them which is where the names on MA came from.
In the novelization, however, the names are all different. They are:
1.) Armstrong
2.) Defiant
3.) Excelsior
4.) Farragut
5.) Mayflower
6.) Newton
