Since then, the torpedoes and torpedo schematics were kept locked away in order to keep in standings with the Temporal Prime Directive. But in 2380, a copy of the torpedo schematics were stolen by General Vekor, of the IKS Hidoken, in an effort to use them against a Borg cube. The torpedoes caused the cube to crash-land on the Mizarian homeworld. (Star Trek: Invasion 101) In 2383, the transphasic torpedoes were installed onto the USS Phoenix-X: by order of Section 31.
