Standard Monotanium Single hull. Standard level Structural Integrity Field
The Ptolemy class tugs are based on the standard Starfleet hull components of the time, but replaced the engineering hull of the Constitution class with a connector at the base of the connecting neck. This could accept a variety of large pods for hauling cargo, passengers, or other stores.
The ships proved invaluable in service, and continued to ply the spacelanes of the Federation for decades. By 2307 they were beginning to reach the end of their operational lives, and Starfleet began to retire them in this year. The last ships were due to retire in 2315, but Starfleet retained six of these ships for a further few years in order to provide a stopgap due to delays in their replacements. The last of the Ptolemy class vessels was retired in 2321.
