Based on the standard Starfleet design tree and hull components of the time, the Ptolemy-class replaced the engineering hull of the Constitution-class with a connector at the base of the connecting neck, which could accept a variety of transport containers.
Ships of the classEdit
Background information Edit
According to Star Fleet Technical Manual from which the class is derived, NCC-3801 is the registry of the USS Ptolemy and is also the prototype of the class.
In the CD-ROM game Star Trek: 25th Anniversary, the USS Enterprise was assigned to recapture a Ptolemy-class Starfleet tug, the USS Masada (NCC-293391) that had been hijacked by Elasi pirates. The ship was described as having a crew of seventeen, captained by Lt. Kevin Keeler.
The Ptolemy-class is also present in the Star Fleet Universe, in which it serves as part of the Federation's logistical network in peace and war. In Star Fleet Battles Module R8, a scenario is presented in which Ptolemy herself is tasked with transporting the crippled vessel Star Tiger out of danger in the early part of the General War.
