The U.S.S. Lachesis is a modified Multi-Vector Advanced Escort built at the Beta Antares Ship Yards, and launched Stardate 85053.08. It has an emphasis on agility, speed, and durability during combat situations. Officially, the ship is meant to be a test and analysis of the strategic capabilities of the genetically engineered Borg One and Two of Twelve. In this capacity, it had multiple skirmishes against Klingon vessels during the Federation-Klingon War. The self-destructive strategies used to obtain victory, however, resulted in Starfleet pulling the ship from the front line systems of the war, with Starfleet Intelligence preferring instead to send the ship on its
current mission to track down and find the remaining ten genetically engineered Borg clones of One of Twelve.
