Template:ShipInfobox The Poseidon-class was a series of United Earth destroyer starships in Earth Starfleet service around the time of the 22nd century.
Specifications
In 2159, these vessels were equipped with ten phase bank and eight Spatial/Photonic torpedo launcher banks, and were protected by polarized hull plating. The Poseidon-class was a contemporary design to the earlier NX-class design and shared many similar components, such as the saucer section and warp nacelle designs. The Poseidon design was a slight modification on the NX as the nacelle pylons were slung underneath the ship, while a dedicated torpedo launcher module was connected to the upper hull. This feature would be repeated across many starship designs over the next 200 years, including the Miranda-class and Nebula-class designs. (ST video game: Legacy)

Background
No explanation is given for these vessels' Federation Starfleet-style registry numbers and their use of the "USS" name prefix, despite existing two years before the inception of the Federation.
The game software included numerous other names for ships of this class that were not prepared to be used in gameplay, and are hidden in the game's source code, including USS Adams, USS Aurbach, USS Boston, USS Commonwealth, USS Concord, USS Fenway, USS Liberty, and Paul Revere. Possibly, these vessels were intended for some feature of the game that was not completed. For example, none of these ships are coded with registry number graphics like those the included ships possess.
This Class was probably Introduced after 2156. since the United Earth Starfleet only had the Intrepid, Daedalus, NX, and the DY-500 class were the only Vessels available in 2156. (ENT novel: Beneath the Raptor's Wing)
