The USS Musashi was a 24th century Federation starship operated by Starfleet. The Musashi fought in the Dominion War. 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")
