The yopyops_poseidon.rar file you have requested: The Outdated Abyss / USS Coto / Poseidon Class (NX Era) - 7.3mb is not available. Perhaps try browsing all files for the game Star Trek: Bridge Commander and upload any files you want to share or are missing. This is the only information we could locate:
Here is the USS Coto a Poseidon Class Starship from about ten years after the launch of the NX Class. This vessel is weaker than that of the NX but makes up for it by being more maneuverable and having more torpedo tubes. This ship is relatively detailed and well made, highly recommended for small battles between Starfleet and Romulan ships of the same era. This ship is based on the similar design as seen in Star Trek Legacy.
