2158 – Torsk

The Torsk class destroyers were designed as multi role vessels. The first intended role was to gather intelligence along border areas, and return that information to the fleet. The Second designed role was to act in a hunter killer role against enemy scout ships. Accordingly the Torsk class was designed to be faster than the Krechet class, but more lightly armed as it was intended for fleet actions.Torsk class ships were the first to carry the improved EFTL-6 warp reactor, which was 30% smaller but only 10% less powerful than the EFTL-5 carried by the Krechet class ships.

Because of the narrowly defined roles that the Torsk class ships were designed to play, they were much less expensive to build and operate than the Krechet class cruisers. They carried fewer weapons, had a 35% smaller crew, and were 25% lighter. Fourteen TORSK-class destroyers entered service from February through December 2158. However, they saw little action in their intended roles as Romulan forces withdraw and consolidated in anticipation of an UE Alliance offensive. They were, however, used as radar pickets and scouts when UE Alliance task forces pushed into Romulan territories in the final 2 years of the war, and five were lost in the course of these actions. Torsk ships did well in these limited roles, but were eventually superseded by the significantly more capable and versatile Powhatan class.

The TORSK-class Destroyer UES STINGRAY (CEM-6) is now on display at the Starfleet Museum.

2158 – U24 Veronus Class (“Chowder”)

The U-24 (Codename ‘Chowder’) was a Strike Cruiser, for use as part of the defensive strategy. Compared to the U-22 Class the U-24 was a far lighter and more manoeuvrable design. This performance improved also included an increase in maximum speed to Warp 3.2.

The U-24 gradually replaced the U-22 in production as the Romulans shifted from offence to defence; operating close to bases meant that Cruisers no longer required the amount of fuel that the U-22 had carried to extend its reach.

In terms of armament, the U-24 did still pack an appreciable punch, again carrying star bomb anti ship missiles and defensive cluster missiles. The class also carried a nose mounted plasma cannon, although this was of lower power than that of the U-22. Frequently, U-24s were employed in an anti capital ship role, their speed and manoeuvrability giving an edge over the lumbering Earth Battle Cruisers and Carriers. They proved to be vulnerable themselves, as the lighter structure that gave the U-24s their speed made them vulnerable to attack from nimble Minotaur class fighters and Powhatan class Cruisers.

U-24s managed to destroy 5 Yorktown class carriers, and 19 other capital ships of various types, but that was at enormous cost, of the 112 U-24s deployed during the war, ships destroyed or listed as missing totalled 82.

Three distinct variants of the U-24 exist. The most common was the U-24A, which entered service in 2258. This mounted a mix of defensive and offensive missiles as well as the Plasma Cannon, 81 of the ships built during the war were of this type. Production continued post-war and a further 38 ships were built of this mark. The second variant (again in service from 2158) was the U-24B, which carried only star bomb anti ship missiles. The Star bomb variant carried by this mark was the lightest (and least powerful) produced by the Romulans, the RM-SB4. It could however carry ten of the weapons, and it retained its plasma cannon as a back up. Some 30 of the completed ships were of this model.

The U-24C, of which saw only a single prototype built, adopted an all or nothing approach. This variant dispensed with all weapons except for the star bombs. As a result, it could carry sixteen of the light RM-SB4s for use against high value targets. The variant was also fitted with a further star bomb in its nose, for use as a last resort weapon in ramming actions.  Intended for use in the defence of Romulus, this variant began testing in mid 2159.  Luckily, for both sides, the war ended before this model saw action. Testing indicated that the ship was woefully underpowered, and could only fire a useful salvo if not manoeuvring or not powering the already inadequate defensive screens, additionally it lost the manoeuvrability that made the U-24A so devastating.

The U-24 was a departure from the larger designs that preceded it. Many things including the changing nature of the conflict and the need for quick to produce ships caused this change. However, the striking power of the U-24 was almost equal to that of many earlier and far larger cruisers; both the Romulan and Federation fleets followed this trend post war, meaning the leviathans that saw action in the Romulan War soon faded into history

2158 – Comet

Following the successful tests of the Fireball class, the UESN made plans for introducing the design into military service to boost the war effort. The Only changes made to the excellent Fireball design were addition of weapons, and the upgrading of the shields to FDS-2.

The Comet class light cruiser began to enter service in October 2158. They were amongst the fastest ships of the Romulan war and saw extensive service as scouts and light strike cruisers. Originally 50 of the class were been ordered, but the end of the war saw the final 25 cancelled in favor of 25 of the Comet derived Daedalus class exploratory cruisers. 23 Comet class ships survived the war, and were allocated to Starfleet, where they served until 2192.

The Comet class cruiser USS Meteor is now on display at the Starfleet Museum.

The Experimental NG (New Generation) engines and shield systems were redesignated as part of the Federation Designation System in 2161.

2158 – Powhatan

The Powhatan class ships were intended to serve as escorts for Yorktown class carriers on strike missions. Since the carriers carried only short-range area defense missiles, they were considered vulnerable to attack by smaller, more maneuverable vessels. If a carrier was accompanied by one or more smaller, heavily armed ships, the mission could be performed with a much lower risk of interference by enemy ships. Even before the launch of the EFTL-5 powered UES Krechet, engineers had begun developing a series of compact reactors for smaller ships. The first to enter service was the EFTL-6 in the Torsk class. Although smaller and lighter than it was also slightly less powerful. This was considered acceptable for border patrol ships, which were expected to operate in a limited geographic area. However, escorts for carriers had to be capable of sustained operations at high speeds for month-long missions into enemy territory.

The EFTL-8 was smaller and lighter but provided higher peak output levels for longer periods of time. Compared to earlier cruisers, Powhatan could be considerably smaller than earlier cruisers but have significantly improved performance, also the sleek lines were also strikingly different, she was long and thin where Krechet had been fat and round. Powhatan mounted a four nacelle system to improve maneuverability, and also used the new J-4A computer, which was a special version of the J-4 for smaller ships.
No carriers under their protection were lost to enemy action in the last 15 months of the war.

The long range, high speeds, and heavy weaponry of the class also made it useful in a wide range of other roles. By early 2159, Powhatans had largely superseded all other small cruisers in the roles of escorts, destroyers, scouts, and cruisers. Several ships were modified to perform intelligence missions deep within enemy territory. Even after the introduction of the Comet class in October 2158, the superior firepower of the Powhatans ensured that they continued in front line service. However, when peace came, a lack of space for scientific facilities meant that Powhatans had only limited use in the new Starfleet. They were replaced in 2185 by the more versatile Moskva class cruisers.

The POWHATAN-class escort USS PHAETON (CEM-18) is now on display at the Starfleet Museum.

2158 – Yorktown

Introduced in June 2158, the Minotaur fighter and the M/AM-powered Yorktown Class carrier were an attempt to overcome the operational limitations of early M/AM ships by combining the speed and range M/AM-powered warp flight with the maneuverability of high-impulse fighters. Yorktown was based on the Pioneer class cruiser, which had entered service in 2154 and had itself been developed from the Bison-class transport. YORKTOWN carried a new M/AM reactor and four paired EFTL-7A warp nacelles. The impulse drive and its fusion reactor were moved to the extreme stern.

At the front of the cylindrical hull, which had been lengthened by some 20 m, were the ship’s sensors and navigational deflector, as well as command centers, the computer core, crew facilities, and life-support machinery. In the center section were docking cradles for 5 Minotaur long-range fighters. In the aft section were auxiliary deuterium tanks, the missile room, and support facilities for the fighters. With a displacement of some 670,000 tons, Yorktown was by far the largest Earth-designed warship produced to that time and would not be surpassed until the Ambassador class was launched in the 2330s.

After the war, many Yorktowns were converted to fast transports and tankers or sold

The YORKTOWN-class carrier UES SARATOGA and the MINOTAUR fighter Gwendoline are now on display at the Starfleet Museum.
