The Thofsin class battlecruiser was 360 meters long and had a standard crew complement of 86. The ship was heavily armed, featuring particle cannons, but it lacked torpedo launchers. In total some 415 ships of this class were built.
The hull was made of duranium alloy. The deflector shields were strong for ships of the era, but the hull was weaker and particularly vulnerable when the shields were down because it lacked hull plating that could be polarized.
Because prior to the advent of the Federation, the Andorian empire was on the brink of war with the Tellarites and Vulcans, the battlecruiser was designed for war as part of a strategy of deterrence.
The Thofsin class was the equivalent of the Vulcan D’Kyr class warship. Five particle cannon emitters were positioned on the fore, port, starboard, ventral and dorsal hulls. Each of the emitters had a 180 degree firing arc. The cannons could be fired as continuous beams and projectile-like bursts.
The main bridge was crewed by five officers. The commanding officer sat in a command chair. The officer’s stations were visible to the commander, this highly efficient bridge design was mirrored in new designs after the founding of Federation Starfleet.
The hull consisted of an engineering section with two weapon/engine pods mounted on wing-like pylon structures. Shuttle and cargo bays were housed in the central hull. A The forward hull section housed crew areas and the main bridge.
The Kumari was one of the most notable members of this class, under Commander Thy’lek Shran.
Design from Star Trek Enterprise, Class name and some details from FASA.
The Djartanna class Destroyer was the mainstay of the Alpha Centauri space navy during the Romulan War, almost a thousand ships were built in total with 316 entering service with the Earth Starfleet.
Effectively a scaled up Zoenamy, the class was quick to build and highly manoeuvrable. Compared to contemporary Earth classes it was shorter ranged, which led to the odd situation of these ‘alien’ built vessels being used to defend colonies and the Terran system while the longer ranged Earth vessels performed fleet duties at longer ranges.
With the outbreak of the Romulan War the Earth Starfleet was in desperate need of ships to supplement the fleet, and the shipyards of Alpha Centauri offered the cheap mass produced Zoenamy as a solution. The design had been developed to meet Alpha Centauri Space Navy requirements for a patrol vessel, and the long range of the design due to it’s efficient propulsion system meant that the design was well suited for adoption by the Earth Starfleet as an escort Corvette. The design was notable as being the first ‘alien’ design adopted by the Earth Starfleet in large numbers to act as an armed picket patrol vessel, some forty of the 119 ships built in total saw service in Earth Starfleet.
The Alpha Centauri Zoenamy class was the basis of the later of the highly successful Djartanna Class Destroyer.
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.
The Mission-X was ordered by Starfleet Intelligence Command in 2248. Externally identical to the standard Mission Class scout/courier, the Mission-X had a combat capability greater than many destroyers and cruisers. The major drawback of the design was the high cost of fitting such components into a small hull. Additionally the design compromised the crew facilites and fuel storage, making missions of more than seven days duration impossible.
Prior to the Four Years war the ships were primarily used in Intelligence gathering duties along the border away from the glare of publicity. But war changed that, as some of these ships were stationed at what became known as ‘Malta Station’ which was beseiged by Klingon Forces for much of the war. The ships assigned to that station earned Federation wide fame for their brave actions supporting the defence of the station. These four ships ‘Faith’, ‘Hope’, ‘Charity’ and ‘Desperation’ collectively destroyed 34 Klingon Vessels, and crippled a further 46. Starfleet refuses to confirm whether the original four ships survived the war, or whether they were secretly replaced during the war after being destroyed.
30 Mark 1 ships were built, and 20 new build Mark 2s. The 18 Surviving Mark 1 vessels were uprated to Mark 2 standards, the only difference being the FWA-2 engine installation.
2256 saw the testing of an enhanced Phaser and Photon Torpedo armed Mark 3 version. This ship was marginally less combat effective than the Mark 2 and more expensive to build. Only the prototype vessel was built of this mark as it was clear that the earlier ships were still highly effective. The Mission-X class was finally withdrawn from service in the 2280’s, it was the last FL/FAC Armed ship on the active service list. Rumours do persist though of special variants still serving with Intelligence command, but these cannot substantiated.
When most citizens of the Federation think of the ships of Starfleet, their thoughts may soar with the mighty designs of the Constitution ,Enterprise and Excelsior classes. However, one of the most successful and influential designs in the history of the Federation is the modest Mission class. This versatile little ship will forever be linked to the success of the Federation in many ways.
The Warrior Class (classed by many as a DW – War Destroyer) was another of the classes that entered service during the Four Years War. The three engine arrangement was chosen to create a Destroyer which was capable of operating with the Federation Class Dreadnought which was due to enter service imminently.
The Warrior was armed with the latest Photon Torpedoes and Phasers, and also was equipped with the best in class warp propulsion systems. The price paid was a very limited range at full speed, this made the class dependent upon deuterium tankers which served to limit their utility when used at high speeds.
