The USS Nightingale was a St Bernards class starship that saw service with the Federation Starfleet during the 24th century.
The Nightingale was primarily designed to serve as a search and rescue vessel but being able to act as a triage facility. However in its construction and design it had a command and control centre built into it and with its advanced sensors it is considered to be a good scout vessel. (Star Trek: Nightingale)
