Ships are used for Exploring and fighting opponents (players, the non-player Ancients, Guardians, and the GCDS). There are four kinds of Ships:
Interceptors (below): Eight per player
Cruisers (below): Four per player
Dreadnoughts (below): Two per player
Starbases (below): Four per player
Bigger Ships cost more to Build but have more space for Ship Parts. Starbases are immobile (see the Build and Move sections for details on Building and Moving Ships).
