2256 – Derf

The Derf was designed as a destroyer leader (Daring Class), but improvements in sensor technology in the Four Years War  rendered this type of ship obsolete. It was then proposed to be re-roled as an exploration cruiser (Derf class), but the decision to produce further ships of the Constitution and Anton classes meant that it could not fulfill that role either. Finally the USS Derf was borrowed for a demonstration of the buoy tender concept. This demonstration was so successful that serial production of the Derf was ordered immediately and eventually totaled 600 vessels over a period of 35 years. Few vessels in Starfleet history have achieved either that level or longevity of production and it is certain that had the class been adopted in either of the other two intended roles it would not have gotten anywhere near either figure.

USS Derf was the only ship of this design commissioned in the exploration cruiser configuration (in January 2256), but she was soon converted for trials as a tender in July 2256.

2267 – Baker

The Baker Class is a notable ‘what if’ in the history of Starfleet’s cruisers. The requirement that the Baker was built for, was for a smaller stablemate for the Constitution Class to replace the earlier Antares class, and to allow the diversion of the smaller exploration cruisers to more localised duties.

The class would have been notable in being the first major new cruiser class designed and built since the end of the four years war. However, in the event though the decision was made that existing Cruiser classes would be sufficient to meet requirements and that the Baker class design was better suited for use as a Destroyer, a role it has proved very suitable for. Only the USS Baker was ever completed as a Cruiser using circumferential warp drive, as part of the refit to Destroyer standards the Baker was refitted with linear warp engines.

2261 – K’Kmarak

The K’Kmarak class was developed as a research ship only. It was never intended for combat and only carries weapons for defense. When the Mk I was commissioned, the need for a research vessel in the rimward areas of the Federation was greatest. As each ship in this class was completed, it was sent to this area to aid in the expansion of the territory. The K’Kmarak was instrumental in mapping this great expanse of space and in establishing contact with heretofore unknown races.

All ships in this class are designed for extended stays and therefore have large living quarters and working areas. Also, ships of this type have some of the most extensive laboratory facilities aboard any Starfleet ship. They are capable of performing the most intricate of planetary studies and have monitored and recorded several novas. It was during one of these investigations that a K’Kmarak class vessel the USS T’Pool (NCC 24307) was engulfed by a stellar explosion that covered 1200 A.U.s in 20 hours. Luckily for the crew aboard, their ship was caught up in a solar wind of phenomenal proportions which pushed away the T’Pool from the main thrust of the radiation. When all had settled, the T’Pool was still intact and flight worthy. The crew, however, had begun to suffer from radiation poisoning within a few days. The ship wandered about for several weeks until it was discovered by the USS Agincourt (NCC 4314), a Larson class destroyer. The crew was beamed aboard the Agincourt and the T’Pool was left adrift with marker beacons on, warning any approaching vessels to stay away. When ships were dispatched to recover the hull, the T’Pool was no where to be found and has not been seen or heard from since.

The Mk II version of this ship mounted the more powerful FWC-2, although maximum warp speed was slightly decreased. The Mk III version has improved firing arcs for its defensive FH-2 phasers. This upgrade was in response to the destruction of the research vessel USS Grissom in 2285 (2/22). After the Grissoms’ destruction, Starfleet reevaluated its research fleet and began a program to upgrade their defensive capabilities.

The K’Kmarak vessels were not built in substantial numbers, but the class is a capable one. All in all, the K’Kmarak class has served its purpose well and is still in service today. It should be noted that all K’Kmarak class ships are crewed by Vulcans.

Of the 14 K’Kmaraks built, 11 remain in active service. One Mk I is listed as missing. One Mk I and 1 Mk II have been scrapped. All remaining vessels have been upgraded to Mk IIIs. The K’Kmarak is no longer in production.

The K’Kmarak class has been named in honor of an early Vulcan scientist and explorer. K’Kmarak vessels carry on in the tradition of their namesake.

2261 – Concorde

Few ships have had such a chequered career as the Concorde Class. Laid down in 2255, the USS Concorde was intended to be the first of a new class of heavy cruiser. The design was built around the new FWF-1 warp drive and featured a number of revolutionary new features; it was intended to be the pathfinder for a whole new style of starship design.

The ships twin forward firing photon torpedoes (FP1 in the original design) were mounted in a bulge on the top of the saucer. The saucer itself was designed with 8 separate segments which were intended to be swappable to allow mission customising. As a result, the FH5 phasers were mounted in the broad secondary hull to allow maximum fields of fire fore and aft. The secondary hull itself was a revolutionary delta shape to increase warp efficiency, and also incorporated two huge hanger bays, as well accommodation for 100 marines.

The Concorde was finally launched in 2261, by this time 11 sister ships had also been laid down. It took another three years to get Concorde into service, and when it finally entered service, after many teething problems, it featured uprated weapons and shields to those originally intended for the design.

The second vessel, Callisto entered service in 2266, some 10 years after being laid down. Compared to Concorde, Callisto mounted a more powerful impulse drive, but was otherwise identical to her sister ship. The delays in getting the class into service meant that they were outclassed by many other newer types, and the unconventional firing arcs made the ships unpopular in military circles.

The third vessel, Comet, commissioned in 2268. This ship had uprated phasers in the form of FH-11, but was also outfitted as a long range explorer to suit its new mission. In initial trials for this role the design was found to be ideal, and the decision was taken to modify the two existing ships, as well as the three that were still to commission.

The problems and escalating costs faced by the class led to a decision to halve the order in 2267. Five of the ships, those that were least advanced, were cancelled, and a sixth, Cornelius, was reallocated for use as an experimental trials ship. The five cancelled ships were Charybdis, Columbia, Constellation, Challenger and Cochrane. Cornelius entered service in 2269, but lacked any permanent weaponry however she was to play a key role in the testing of many new weapon, shield and propulsion systems over the next 25 years, The next standard ship due to commission, Comet, was chosen to be reprieved as another potential role had been suggested for a small number of ships of this design. Galaxy Exploration Command needed a small number of large ships for long duration missions to the galactic core area, and the Concorde design, a failure in its military role, was the prime candidate due to its long range and duration.

Both Concorde and Callisto were soon modified for this new role, and along with the Comet set out on long range exploration missions. A fourth ship, Corsair commissioned in 2270, and for the first time the class was receiving positive attention. This was sadly to change in 2271, when Callisto was lost, presumed destroyed, on a mission to investigate the great barrier.

The loss of Callisto cast a shadow over the class, and delayed the commissioning of the fifth ship, Centaur. Investigation into the loss cleared the design of blame, and resulted in a ban on crewed missions to the great barrier. Centaur, which finally commissioned in 2274 was also a Mk 3 ship, and was again assigned to the long range exploration role.

The sixth ship to be completed , and the only new build Mk4, Commanche, commissioned in 2276, some 17 years after the hull was first laid down. The Mk4 was a major evolution in the class, as it mounted the new FWG-1 warp drive, coupled to a pair of M-6 computers and FSP shields the Commanche had a superb turn of speed and excellent defences to add to the already impressive range of the class. Another change in the Mk4 was that the segmented primary hull sections were fused together permanently, which greatly reinforced the strength of the primary hull. The Commanche was almost immediately despatched on a planned 10 year mission, deep into unknown space. She returned from the mission in 2288, six months behind schedule, but with a wealth of data and knowledge.

Concorde herself was upgraded to Mk4 standards in 2278, and was also despatched on a long range mission, which she returned from in 2288. Refits to a Mk5 configuration, with FWG-2 warp drive and FIG impulse drives, were considered for the other three ships, but the perceived complexity and limitations of the design led to the decision being made to phase the class out of service prematurely. Comet was placed in reserve in 2284, Corsair in 2286 and Centaur in 2287 as they returned from their missions.

Upon its return to Federation space in 2288, Commanche was spared decommissioning, instead she was used as part of a Starfleet goodwill mission, trying to recruit new recruits into the fleet. Concorde, on the other hand, was decommissioned as soon as she returned from her mission in 2288, and the Commanche finally followed in 2291.

The fate of the class seemed sealed in 2295 when the Centaur was scrapped, as newer classes such as Excelsior were in the ascendancy. The following year the Commanche was taken out of storage, and was due to be dismantled. Fate intervened though as the old trials ship Cornelius had been used as a testbed for the new FWL-2 warp drive, was producing stunning results. In 2297, following successful completion of the engine trials aboard Cornelius, a surprisingly bold decision was made to reactivate the four surviving ships of the class and refit them for further service, and a decision was also made to evaluate the possibility of refitting the Corneliius for active service.

Indeed, so successful has the class now become, it is suggested that the basic design could one day be used as the basis for even larger exploration vessels. Although the oldest ship in the class was laid down almost 50 years ago, she has only seen service for about 20 years, so it is likely that this class could survive in service until the mid 24th century. Upon reflection it is evident that the design was sound, but was too advanced for the technology of the time, as a result it took too long to commission, and was too expensive and complex for extensive production. Once technology had caught up with the concept, the class was able to prove its worth.

2249 – Canopus

The Canopus Class Research Cruisers were designed to carry out the first detailed survey work on the Sagittarian arm of the Galaxy. 24 Ships of the class were proposed, the design was lightly armed, but to compensate was equipped with state of the art FSI trinary shielding.

15 Ships were produced in this initial configuration, but only 12 actually entered full service with Galaxy Exploration Command, the final three ships were refitted while working up to the new Mk3 configuration. The Mk 1 served until 2258 when the last vessel was refitted and upgraded. Two ships of this mark are known to have been destroyed, while a third USS Capricornus vanished without trace in December 2255.

The intention had been to introduce the Mk2 in 2253, with upgraded FWE-2 Warp drives, but no additional weapons. However, events were to cause Starfleet to require a very different type of cruiser. The outbreak of the four years war led to the modification of the design to produce the Mk3, which mounted more powerful lasers in more mounts, as well as accelerator cannon. The high speed, and excellent shielding of the Canopus design making it an ideal long range reconnaissance cruiser. The prototype Mk2 was renamed USS Centurion, and entered service in 2253 as the first Mk3, and was followed by a further 5 new build ships. Three recently completed Mk1s were pulled back from working up and upgraded to the new standard. Three additional Mk1s were upgraded as they returned from their missions.

Mark 3 Canopus class vessels frequently operated on their own, deep inside enemy territory, the small profile of the design linked to classified ECM systems making them virtually impossible for the inferior Klingon sensors to detect. As a result of this high risk mission, 5 Mk3 ships of the 12 built or converted were lost during the war.

The 22nd and last production vessel USS Cavalier was completed as a Mk4 with Phasers and a single photon torpedo launcher. The ship commissioned just in time to catch the end of the war. All of the 13 surviving Mk1 and Mk3 ships were refitted to the Mk4 standard between 2257 and 2263, but 8 proposed new build Mk4s were cancelled as production of additional Constitution class ships was deemed preferable. Post war the class returned to its scientific mission profile, but the enhanced weapons were retained.

The class continued in service until 2286, although numbers were steadily reduced from 2275 onwards by a intense program of scrapping and sales. The reasons for this was a combination of the craft being too small to operate effectively in a long range exploration role or to be equipped with modern sensors, conversely they were too large and crew intensive to operate in a short range exploration role in a military configuration. Despite this, civilian research groups now own a number of Mk4s, as the removal of the weapons upon sale permitted a major reduction in crew complement and released the space for the fitment of modern sensors.

In 2290 it was realized that not a single ship had been retained for the Starfleet museum, as a result the former USS Canopus was repurchased at scrap prices in a very poor condition, and is now being restored to its former glory.

2244 – Anton

The Anton Class shared its basic design concept with the Coventry class frigate, but in terms of equipment there were major differences as the Anton was equipped as a Research Cruiser with roughly half the weapons capability of the Coventry class. The Anton class having an enhanced science fit instead as befitted its role as a research cruiser.

First commissioned in 2244 during the period known as “The Great Awakening”, the Anton Class cruiser was in the forefront of that expansion effort. At the time, Star Fleet itself was expanding in response to the changing and expanding economic and political goals of the UFP. To meet the demand of a larger navy, the Military Appropriations Committee authorized the development and testing of hundreds of vessel types, the Anton among them.

During this same period, the concepts of ship design were rapidly evolving and becoming more sophisticated, and the technology to build and operate starships was going through an industrial revolution. Advances in all facets of the technology required to construct, maintain, and operate a starship was changing so rapidly that some ships were obsolete before they were completed. The Anton design was changed no fewer than 12 times before the tooling and machining was begun. Even so, the ship required some alterations during its trials and was to see many more changes after its commissioning, the last of which was the refitting to the Reliant Class.

When these new cruisers were launched, they were only capable of performing 3-year missions with re-supply at 1-year intervals. This made their dual-purpose role of research cruiser harder to perform. With the great distances that had to be traveled, they could not get more than 6-months travel time from a friendly outpost. This meant they could only advance as fast as the frontier was expanding.

2230 – Antares

The Antares class survey cruiser was designed for longer range duties than her recent predecessors, the relatively large secondary hull giving greater storage capacity for consumables and fuel, as well as an ample supply of survey drones. The class gained a reputation for toughness and reliability as the simple no frills design served well for almost 60 years despite the loss of the class ship.

The USS Antares,  lead-ship of this class was lost with all hands on March 30th 2239. The name was next given to a freighter which was lost with all hands in 2266.
