2148 – Thofsin

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.

2151 – U19 “Warbird” Class

The U-19B entered service in 2154. If it had been available in large numbers, it is possible that this ship would have won the war for the Romulan Empire.

The original U-19A began testing and evaluation in 2151, the trials proved it to be a superb vessel; it far outclassed any Earth ship, and was not far behind Klingon or Vulcan technology.

The U-19A prototypes were assigned to the Tal’shiar for testing. The Tal’shiar had obtained a number of Suliban cloaking devices, and installed them on these ships intending to use them as surveillance or covert operation ships. One of the ships was used to obtain close in scans of the Earth’s NX-01 UES Enterprise in 2152 after that vessel strayed into a minefield.

In November 2152, the three ships, in company with three U-13As, were deployed on an intelligence-gathering mission in what is now known to be Tholian space. The U-13s, acting as support ships were trailing behind the U-19s when they vanished from sensors. When the U-13s caught up, they found the U-19s caught in some kind of subspace flux. No other ships were in the vicinity or had been detected on sensors, and it was concluded that the cloaking devices were to blame. As the only people with real knowledge of the cloaking device technology were aboard the ships, the cloak programme suffered a setback from which it would take almost a century to recover. Additionally, only three cloaks had been procured from the Suliban, and an increase in tension following Suliban incursions precluded negotiations for further units.

The fourth prototype U-19 was completed to the same design, but without the cloak. Concerns existed about the cost and time required to build the ships, the U-19 cost 8 times more than a U-15, and took over four years to build each unit. The U-19A design was modified to simpler hull and nacelle design to become the U-19B. The U-19B still cost 6 times more than and requires three years to build, compared to 8 months for one of the simpler U-15s. This was largely due to the use of the immensely light and strong, but scarce and expensive metal Tritanium in the primary hull structure and plating. The wing assembly used duranium as all other Romulan ships did.

As a result, only 24 U-19Bs were completed before the end of the war (and a further 12 post war), and most of these were deployed along the Klingon Frontier to stop a much-feared invasion while the Fleet was occupied elsewhere. A single U-19C was completed to evaluate the use of duranium for the primary hull, but was deemed a failure, and was cannibalised to produce the U-21 prototype.

There is no doubt that had mass production of the U-19 been practical the outcome of the war would have been less certain, and were it not for the intervention of what is now called the Tholian (or Defiant) rift the cloaking ability of the U-19A could have caused havoc

2194 – Hyperion I

Early Federation exploration efforts were hampered by the lack of effective communication between command and distant ships, all long range communication required the user of booster buoys. By the mid-2190s, transtator based subspace transmitters were compact enough to be suitable for fitment to Starfleet vessels other than specialized communications ships. The first ships to carry the new compact transmitters were the Hyperion Class Cruisers launched in 2194. The class had initially been designed as a exploratory follow-up to the Moskva class of 2179. However, when the Mercury subspace communication and sensor system became ravailable, the Hyperion class was seen as an ideal platform. The Mercury system was mounted in a specially shielded housing on the primary hull.

The Hyperion class design’s basic structure and equipment were otherwise generally similar to the Moskva class, with eolutionary improvements to ship’s systems. The primary hull had become a flatter biconvex disc that was raised above the longitudinal axis of the secondary hull. The warp drive system comprised the FFTL-3B matter/antimatter reactor powering twin warp nacelles.

A dividend of the long-range subspace sensor was higher starship speeds, and the Hyperion was one of the first classes equipped with the new ‘B’ series warp drives. Earlier ships were limited to speeds less than warp 5 because their short-range navigational sensors gave at most a few seconds’ warning to avoid objects in their paths. The new sensors linked to the L series computers allowed Warp 5 to be reached safely for the first time since the NX class with its experimental Vulcan sensor suite.

Perhaps the most famous ship of the class was USS Triton, which had an unfortunate contact with the Klingon Empire while attempting to establish diplomatic and commercial relations. As modern diplomatic protocols had not yet been introduced, Triton’s captain, Natalia Thibodeaux, decide to beam herself and a diplomatic team into the Great Hall on Qo’onoS on October 11, 2218. Unfortunately, the Klingons had assembled in the Great Hall to celebrate their “expulsion” of the H’urq 11 centuries earlier and killed 7 members of the first-contact team. Thibodeaux and the survivors of the team managed to beam back safely, but USS Triton was severely damaged and nearly brought out of orbit by Klingon attacks. A total of 32 crew members were killed. By the time Triton limped back to Starstation McCall, the Federation was on the verve of war with the Klingon Empire. These hostilities led to the four years war some 40 years later were unremitting for the next 80 years until the signing of the Khitomer accords.

Ships of the Hyperion class served in a wide range of roles, including long-range explorers, command ships, border-patrol ships, and escort/sentries. Several ships also served with civilian agencies, such as the UFP Institute of Science. However the class was relatively lightly armed and rarely used in a front line role The last ship was retired from active service in 2229.

USS Pacatrix, which saw extensive service as a long-range explorer both inside and outside Federation space, is now on display at the Starfleet Museum.

2151 – NX

The NX class Cruiser is often neglected by history, as the ships which followed it into service gained fame in the Romulan War. The NX class introduced the Matter/Antimatter powered drive system into service, however experience with the class in operational situations, the cost of the drive system and problems with mass production led the high command to decide to revert to mature technology that fusion power represented for the next designs to enter service.
