Notes

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. [1]

The pods hauled by the Ptolemies were divided into five main marks. Each were given their own NCC numbers, in line with their Mark number; Mark I pods were designed for bulk liquid carrying, and were given NCC numbers in the 1000 range. Mark II carried dry bulk goods and were given NCC numbers in the 2000 range. Mark III reefers carried refrigerated goods with numbers in the 3000 range, Mark IV "star liners" carried personnel and were given numbers in the 4000 range, and Mark V general cargo hulls received numbers in the 5000 range. [1]


The ships proved invaluable in service, and continued to ply the space-lanes 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.

Comments

This ship is almost exactly as described in the Starfleet Technical Manual by Franz Joseph. The strengths of the weapons and defence systems are my own invention. The mass has been raised from the the TM's figure of 126,500 metric tons; since TOS establishes that the Constitution is far more massive than the TM suggests, I have raised the mass of all these ships in line with the canon figure.
