After the attack on Salem Station, when the Intrepid and Delta class ships were deployed to the front lines, the Poseidon Design Team had to quickly design a new class of ship for picket defense of the Sol System. A "kit bash" of components from other ships resulted in the Poseidon design which, while slow, was heavily armed with photonic torpedoes. Due to their limited speed (max wf 3.5), the Poseidons saw little action, though they did participate with Red Squadron on the attack of the Forge in the winter of 2157.
Notable Ships of the Line:
Ajax, Zeus, Poseidon, Coto, Athena, Miranda
