USS Invincible (NCC-1861)

USS Invincible (NCC-1861) was a starship in active Starfleet service during at least the 2270s and 2280s.

Captain Philip Styles was Invincible's commanding officer in 2275. He had a reputation for being very "by-the-book" -- giving demotions where other commanders such as Clark Terrell would have given commendations. (: "The Blue Rose")
