Refit and retrofit are the processes by which a starship (or any other type of vessel) is overhauled and re-outfitted with newer technology.
[edit] Refits
A refit is the installation of updated equipment aboard a starship. It differs with a retrofit in that the vessel's overall structure is changed during the process. A refit requires some form of spacedock. (Star Trek: The Motion Picture, Star Trek V: The Final Frontier, Star Trek VI: The Undiscovered Country)
- During the mid-22nd century the Romulans modified one of their Warbirds into a drone-ship. (ENT: "The Aenar")
- The original USS Enterprise underwent a major refit beginning in 2270 which essentially turned it into a new vessel. The refit, which required 18 months in Spacedock, involved changing or reconstructing a majority of the ship's systems, including the weapon's systems and warp drive. (Star Trek: The Motion Picture)
- Following the Enterprise's battle with the USS Reliant, Montgomery Scott informed Captain Kirk that the refit time required until the ship could be taken out again would be eight weeks, but that he could do it in two. Kirk then noted Scotty's propensity to multiply his repair estimates by a factor of four, to which Scotty replied, "How else can I keep my reputation as a miracle worker?" (Star Trek III: The Search for Spock)
- The USS Lakota was refitted in 2372, just before Erika Benteen took command. The refit included upgrades to weapons beyond the norm for an Excelsior-class ship, including quantum torpedoes. (DS9: "Paradise Lost")
[edit] Retrofits
A retrofit is the installation of updated equipment aboard a starship. It differs from a refit in that the vessel's overall structure remains unchanged in the process - the components in question are simply swapped out. A retrofit may not require a spacedock.
- A standard part of retrofits is to switch out the bridge module of a starship design. Bridge modules may appear radically different from previous versions, while the structure of the starship may remain the same. (Star Trek: The Motion Picture, Star Trek V: The Final Frontier, Star Trek VI: The Undiscovered Country, Star Trek Generations)
The concept of replaceable bridge modules was developed to explain why the bridge of the Enterprise and USS Enterprise-A appeared completely different over the course of various films, or the USS Enterprise-D between seasons 1 and 2, and season 7 and Generations.
- In late-2370, Captain Keogh asked Chief O'Brien to retrofit Deep Space 9's Danube-class runabouts with an extra complement of photon torpedoes prior to joining the USS Odyssey on a rescue mission to the Gamma Quadrant. (DS9: "The Jem'Hadar")
- In early 2372, Benjamin Sisko told Kasidy Yates that Deep Space 9 was being retrofitted, although in actuality it was being upgraded with new weapons systems. (DS9: "The Way of the Warrior")
