The USS Musashi was a Federation starship in service during the Dominion War in the 2370s.
In 2375, the Musashi was involved in a series of complicated trades for engineering equipment orchestrated by Ensign Nog of Deep Space 9. Nog traded an induction modulator to the Musashi in exchange for a phaser emitter. (DS9: "Treachery, Faith, and the Great River")
