| 1/9409.01 | 02/23/2252 | The "Loknar" class frigate USS "Morgan City" (NCC-2704) is captured by Admiral Kamato's forces. It will later be renamed the IKSV "Straave'eMara" ("Slave Of Justice") and be used in Kamato's abortive coup attempt on the Klingon throne. After failing, Kamato will retreat into the Triangle taking the "Loknar" class frigate with him. From their location in the Triangle, the Klingon rebels will attack unprotected convoys and merchant vessels by using the "Straave'eMara" to lure them in. This ruse will last several years until the general recall of all "Loknar" class vessels make it difficult for the Klingon vessel to operate. The IKV Admiralty eventually decides to have the vessel painted in the standard steel-gray color of their Navy and keeps the ship in active service. | FASA | Federation Ship Recgonition Manual | The Four Years War | Morgan City Incident |

| 1/9409.27 | 03/22/2252 | The Kobayashi Maru (NCC-S3700) class neutronic fuel carrier is authorized for construction. These carriers will be essential for the supply of fuel to less advanced civilizations that have not yet developed matter/antimatter power systems. The "Kobayashi Maru" carries 20 fuel modules, a standard complement of 81, and has warp 8 capacity (after upgrade). These ships utilize unique self-contained SC35/1-45F nacelles on a rectangular hull. As originally launched, ships of this class will have only warp 6 capacity and laser banks for ordnance. They will later be upgraded to Mk-II-S phasers (4 emplacements) along with warp drive on stardate 7809.13. 74 ships will be built although they reportedly originally utilized a more complex registry system (the class ship possessing the registry NC3-HT03-23682). This class may have been named after the Kobayashi Maru test given at the Star Fleet Academy, which was in turn named after the S.S. "Kobayashi Maru" (MCC-34/070) merchant. | Jackill's | Jackill's Volume 3 | | |

| 1/9507.22 | 02/06/2253 | About this time, with Star Fleet facing the task of protecting supply convoys against enemy small attack craft, the "Santee" (NCC-1925) class escort carrier is developed from 4 partially constructed neutronic fuel carrier hulls built for commercial concerns and purchased by the fleet (a practice common during the early stages of the war). They are completed using specifications and components similar to those designed for the "Bonhomme Richard" class. To provide additional room in the secondary hull for embarked craft, the warp nacelles and systems are mounted together in an expanded impulse deck--a configuration which will lead to designs on many later carriers such as the "Youngblood," "Jenshahn," and "Chosin" classes. These ships (NCC-1925-NCC-1928) are placed in immediate service to escort replenishment groups to the starbases and outposts nearest the war zones. They will be later utilized for raids against smaller targets, special operations, and diversionary tactics during major offensives.

Both classes are built at incredible speed, but have many crucial systems hardwired to allow them to be built so quickly. This make upgrades difficult at best.

| 2/0405.01 | 07/05/2262 | The D-11B "Dath D'lan" ("One Wing") class destroyer enters service in the Klingon fleet. The most unusual design in the Klingon Imperial Navy, it is easily recognized on visual scan because of its single wing. It fares poorly in battle due to its asymetrical design, which works to restrict the field of fire from the weapon mounting hardpoints. Nevertheless it has a maximum warp of 8 and a crew of 218 with 220 passengers. This class will inevitably be utilized for light assault duties, having the capacity to carry a company of marines, and used to secure lightly-held systems. They also are reported accompanying D-9 research cruisers in their efforts to open new territories. | FASA | Klingon Ship Recgonition Manual | | |

| 2/0702.01 | 06/18/2265 | The "Derf" class tender USS "Acropolis" responds to signals from a malfunctioning marker buoy. As its shuttle nears the beacon, a Klingon warship appears and opens fire before defensive action can be taken. The engines of the "Acropolis" are crippled and the tender is boarded and towed into Klingon territory. Intelligence later discovers that the beacon had been planted by Klingon operatives to entrap the repair tender. It is theorized that the Klingons gained technical information concerning robotics and repair techniques that they lacked, but it is not known just what gain this action brought them in the overall situation. Some analysts believe that study of the robotic repair systems will make it possible for Klingons to alter the functioning of navigation beacons robotically, creating potential havoc in border spacelanes. | FASA | Federation Ship Recgonition Manual | | |

| 2/0706.28 | 02/18/2266 | The upgraded "Kepler" (K-1) class deep space trading station is authorized. These stations will be constructed by Star Fleet division's orbital assembly station at Starbase 16 for peaceful access in neutral space. Designed for extensive cargo handling and to provide recreational facilities for passing ships, each trading post consists of a central hub and three radially-attached arms. Unlike the early K-1 series design, these newer stations are larger, featuring linear intermix matter/antimatter reactors in place of nuclear fusion units. In addition, they possess 27 docking ports on the central hub. By the end of the 23rd Century, a total of 96 such stations will be constructed, each housing from 798 to 1,130 personnel and (at least in later years as not initially intended to be military installations) 12 optional phaser emplacements. Before the 2270s, 17 will be in service, located in remote and little-developed regions of the U.F.P., originally intended for the support of colonization efforts on the Federation frontier. | Jackill's | Jackill's Volume 1 | | |

| 2/1109.29 | 07/26/2269 | An abandoned Romulan planetary base is discovered on Eridam, a mining world near the Triangle, with its Romulan inhabitants wiped out by an epidemic disease known to affect Vulcans. No military information is gained, but personal diaries, children's books, works of fiction, and other non-military writings are discovered. This body of work, known as the Eridam Papers, adds much to the U.F.P.'s meager store of knowledge about the Romulans. The Vulcan connection is supported by anatomical drawings, by Romulan legends, and by children's history books. Romulan history and motivations become better understood, giving some basis for understanding what has been a 'faceless' enemy. Based on the Eridam Papers, some political thinkers speculate that negotiation may be possible with the Star Empire, though others see no hope for negotiation and press for even stronger measures to curb what conservatives have come to call the Romulan Threat. The net result is both a stronger military presence along the Neutral Zone and near the Triangle, and a push to gather as much intelligence data as possible about the Romulans in hopes of making field commanders more aware of Romulan capabilities and tactics. | FASA | Romulan Way: Game Operations Manual | | |

| 2/1204.02 | 10/15/2269 | The "Anderson" (NCC-8400) class heavy scout is authorized. Ultra-fast and cost effective, this class will be used for patrols, surveillance, and U.F.P. defense. It is another attempt at tandem nacelle deployment below the dorsal pylon, giving the "Anderson" class a long, slender warp field for increased speed (warp 9.3 maximum). Its primary mission will be extended reconnaissance patrol into critical areas ahead of U.F.P. vessels, using her extensive surveillance equipment. During normal operations the "Anderson" class vessels will perform both surveillance and picket duty around capital ships. This class will carry a standard ship's complement of 370, consist of 75 vessels reportedly and carry the relatively light armament of 12 phaser emplacements and 2 torpedo tubes. | Jackill's | Jackill's Volume 2 | | |

The Romulan force consisting of a Type 1 V-6 ("Gallant Wing") class cruiser and three Type 7 T-2 ("Death Talon") class destroyers. The Klingon commander, confident with his new ship, presses an attack, only to find the Romulan cruiser his equal. After several exchanges of fire, the Klingon force suffers the loss of three D-11s, and the L-13 sustains serious damage. The Romulan cruiser receives moderate damage and one destroyer is eliminated. The Klingons, fearing the loss of the battleship, begin to withdraw from the battle. The Romulan commander decides to counterattack the retreating Klingons. The huge battleship disables another of the Romulan destroyers. At this point both sides disengage; the Klingon ships withdraw to Klingon space while the Romulan commander returns to the area of the battle and salvages what he can of the ships, taking in tow a disabled D-11. This skirmish proves to the Klingon Imperial Command that the L-13 needs improvements.

Neither race learn much from this encounter. The Gorn recover no wreckage and are not even certain the ship is not of Federation origin, despite it's strange appearance. The Romulans are not alarmed as scout missions are inherently dangerous and many scout do not return. | FASA | The Romulan Way | First Gorn-Romulan Confict | |

| 2/1703.02 | 12/19/2271 | The USS "Avenger" (NCC-1860) heavy frigate is recommissioned. These new heavily-armed vessels equipped with 4 megaphaser cannons, 4 photon torpedo banks, and 12 standard phasers, will form the basis of the "Knox" frigates to be constructed in the future. With a complement of 360 and a warp capacity of 11, a total of 22 ships of this class will be built. Smaller and slower than the "Belknap" strike cruiser, the "Avenger" possesses increased maneuverability and fire-power, added to the enormous hangar facilities, allowing it to carry a squadron of "Killer Bee" attack craft. They are ideally used for patrolling the various small neutral zones in the U.F.P. Treaty Zone and the Orion system. | Jackill's | Jackill's Volume 1 | | |

This class of ship was built to quell the rising tide of outlaw activity in the Orion star system and the Deneb/Rigel commerce zones. Built to be manned by a 50% Rigellian crew, these ships have a higher deck height and increased oxygen atmospheres. The "Hornet" is also unique for possessing no secondary hull but instead a sensor/ deflector platform attached to a fractional primary hull disc--the predecessor of the late 2280s' "Akula" class perimeter action ship. "Hornet" class fighter-carriers deploy 10 "Hornet" class (warp 3 capacity) fast attack craft to track Orion smuggler ships into asteroid field bases (the predecessor of "Killer Bee" assault craft) and with their own warp 8 capacity speeds and complements of 172, they are formidable starships.

Long-range coupled with truly high speed capabilities make the "Ascension" and her sisters ideal for investigating trouble spots throughout the U.F.P. Treaty Zone--as they happen, and especially for emergency rescue operations. For these reasons, they are stationed in a disperse pattern throughout the U.F.P., with at least one based at every major starbase. | Publication | Starfleet Prototype | | |
