NOTES:
The Antaries Class was most clearly a vessel that is a generation older than most vessels in service of the Federation's civilian transportation companies. I contemplated that during the 23rd Century the original Antaries class design was constructed for the Federation civilians. They have of course served in the corporate sector for a nearly a Century as cargo carriers and civilian passenger transports. Do to the designs of the Antaries Freighter the embedded Warp Nacelles would have to be a standard.

Additional Adjustments to the Antaries Class that makes a versitile vessel.

Optional additions to the ship
this is to upgrage the vessel that changes the vessel to multi roll vessels while making it inter changable.
