2242 – Ptolemy (Modified)

The Ptolemy class transport was the first in a line of successful high-load warp transports used by the Federation. Equipped with specially designed warp engines suitable for towing mass never before realized, the vessels were a boon to infrastructure building outside the core of the Federation. Initially, production contracts called for 30 ships of this class to be constructed. However, due to the fleet-wide ship build-up at the time it was commissioned, limited appropriations permitted the construction of only 15 of the class.

The Ptolemy class was designed for easy and efficient transporting of cargo within outboard cargo containers. The cargo containers were easily attached and detached via a specially designed coupling unit fitted to the neck of the primary hull of the starship. Depending upon total mass, up to two containers could be towed by the Ptolemy at one time. These containers were mass-produced and supplied to both Starfleet and private shipping concerns (at a reduced rate) to promote the use of these standardized containers. Practically a ship unto themselves, these containers were a break-through in shipping technology just as the high-load warp engines mounted on the Ptolemy were.

The containers came in five basic types:

  • Mk I Liquids
  • Mk II Dry Bulk Goods
  • Mk III Refrigerated/Thermal Goods
  • Mk IV People (starliners, mass transport)
  • Mk V Products (non-food stuffs and misc.)

The Mk I-III and V containers had their own cargo transporters (up to six), turbolifts for carrying goods to various levels and self-contained environmental machinery. The Mk IV containers also included 6 personal transporters and could accommodate 800 passengers. This container also had its own sensors array, was capable of sub-light speed and could sustain its passengers in case of an emergency for up to 18 years.
During the Four Years War, an urgent need arose for military cargo transports. Because of their slow speeds, the Ptolemy was not a viable candidate. However, the need was so great that all Ptolemys in service at the time were converted to Mk IIs. The Mk II mounted the FWB-1 engine which improved the speed of the transport, but at the cost of limited cargo capacity. The Mk II could only carry approximately 121,000 mt of cargo in smaller outboard cargo containers. However, this was sufficient in its role as a military transport.

After the Four Years War, surviving Ptolemys were retrofitted with the FHLWA-1 and returned to their pre-war roles. Many of the Mk IV containers were converted to starliners, with luxurious accommodations for up to 500 passengers. These starliners contained a park promenade, numerous recreation lounges, 2 full theaters, a gymnasium, pool and hydroponic gardens.

This modified version was first built in 2242 alongside the standard version, it featured more discreet hull mounted deflectors as opposed to the large dish of the standard ships. Post war most of the class were converted to this standard, which gave no performance benefits, but considerably improved reliability.

2248 – Siva

The Siva class single engine destroyer was an adaptation of the Saladin class building upon feedback from the active Service of that class. The Siva used the FWC warp drive  rather than the FWD of the Saladin. This provided a potent mix of  speed and maneuverability as well as additional power compared to it’s older cousin (however the balance returned to the Saladin in 2255 when the FWD-2 equipped Saladin Mk2 entered service). The internal arrangements of the Siva were considerably different to those of the Saladin, hence the classification as a new class as opposed to a new mark.

Unusually the prototype of the class was the USS Siva from the Siva class of 2243, damaged beyond sensible repair she was massively refitted to this more standard configuration as opposed to the missile armed configuration of the previous design. Upon the recommissioning of the Siva in this new configuration the former class was renamed the William Howe class.

2247 – Modified Saladin

The Saladin was the Destroyer version of the Hermes class scout. The class was 50% more powerful than the similarly sized Larson class. The Saladin was often deployed in Destroyer groups to hunt down enemy shipping. These groups were frequently led by a Cygnus class command ship.

A number of vessels of this class were built in an experimental configuration with a neck mounted deflector dish, instead of the original that was mounted below the primary hull. This modification improved reliability of the deflector system, but did not affect combat performance.

2247 – Modified Hermes

The Hermes class scout was based on the same design as the Saladin class destroyer. As it was more powerful and than the earlier Nelson class it was generally assigned as a scout for battle fleets.

2246 – Cygnus I

The Cygnus Class entered service in 2246 as a Command Courier version of the highly successful Saladin/Hermes class. The Intention was that an Admiral could use the ship as a sector command post. To this end the design was given the FWC-1 warp drive, giving it more power than its half sisters, the weapons were entirely laser based to make more room for the Admiral’s facilities and command centre.

In 2250, the USS Columbia was converted to a more heavily armed configuration as an experiment to evaluate the benefits of an FWC-1 powered heavy destroyer type. These trials amounted to nothing, but the Columbia was left in this configuration, and was assigned as a Destroyer Leader to a flotilla of Saladins in the Klingon Border Area.

The outbreak of the Four Years War saw a major change in Starfleer Operational Procedure, a number of the Cygnus class ships were involved in near disasters in 2252, as operating independently without escorts as they had been designed to do made them tempting targets. In a fleet role the additional speed of the Cygnus was wasted, so it was ordered to convert the other 8 mk1 vessels to mk2 standards.
