Tenders vary in displacement and capability, from shuttle tenders (e.g. USS Scopus) up to "Murphs" — Pearl-class mobile repair facilities. Their purpose is the repair and maintenance of starships when starbase facilities are not immediately available. Tenders have stores of tools and spare parts — and, by the early 24th century, replicators. They are crewed by engineers and technicians and may even have alien technologies officers who are familiar with the technology of non-Federation civilizations.
- As hospital ships are designed to handle casualties beyond the capacity of any one starship's sickbay, so are tenders designed to effect repairs beyond the current or expected scope of a single starship's damage control teams.
In 2295, upon completion of a mission in the Tengen system, USS Malverne was scheduled to dock at Komarov Station, but docked instead at Shadowstar Station, where the fleet tender Puget Sound was located. (Star Trek: Malverne: "Police Action")
