- For an overview of playable starships within Star Trek Online, see the Playable starship article
There are many types of non-playable starships for each faction, ranging from civilian freighters to enemy warships that the player must overcome in space combat. Players will encounter these ships while in space, either when running missions or traveling between star systems.

Fighters (also known as shuttles or small craft) are the weakest NPCs found on space maps. Equivalent to Neophytes, they are even weaker than frigates and are no match for players.
Some fighters, such as the Orion Interceptor, are launched from higher-level ships (carriers).
Frigates (also known as Corvettes or Light Cruisers) are small, maneuverable vessels used by almost every faction. They are generally the weakest NPC vessels in the game (aside from Fighters), and as such they typically appear in groups of three.
Frigates generally carry three or four weapons and only a couple of abilities.

Escorts (also known as Destroyers or sometimes Cruisers) are smaller vessels that typical serve in the front line attack role, engaging at point blank range with forward-facing cannons and torpedoes.
They typically pack a tremendous punch and have great agility and speed compared to cruisers and science vessels. Escorts favor forward-facing weapons and an outstanding turning rate. However, they have a smaller crew and weaker hull and shields.
Battleships are the second most powerful NPC vessels used by factions, outgunned only by the dreadnought. They have very strong hull and shields, five or six weapons slots, and a wide range of abilities.
To compensate for all their power, battleships are very slow and not at all maneuverable. Some battleships, such as the Breen Capital Ship, are carriers capable of launching fighters.
- You may be looking for the playable Federation Dreadnought Cruiser.
Dreadnoughts are the most powerful NPC ships in the game. They are comparable to battleships in terms of speed and weaponry, but they have much stronger hull and shield strength.
They are dangerous and resilient to the point where defeating a dreadnought usually requires more than one ship (player or NPC regardless). Some dreadnoughts, such as the Klingon Vo'quv, are carriers capable of launching fighters.
