As a Shrike-class vessel, the Blade bore a close resemblance to Defiant-class escort ships.
Sometime in 2381, Captain Koran Lacer took the Blade's captain's yacht, the USS Diligent, on a mission assigned by Section 31 to the Nor'Shizi homeworld. There he bombed the planet and destroyed nearly 95% of the population. The attack was retaliation in an ongoing conflict between the Federation and the Nor'Shizi in the Gamma Quadrant. Koran was later put on trial for his actions. (BNW: "Right of Space", "Threads of Fate")
