Designed to outgun and overpower any other cruiser by at least 100%, as well as most starbases, and even some planetary defense systems, the Yamato-class heavy battleship is the latest "final word" in ship combat and is, at 1284 meters of estimated length, among the biggest starships ever fielded by Starfleet.

OverviewEdit

The hull configuration of the Yamato-class is comparable to other established Starfleet vessels. It carries the maximum amount of weaponry which can be packed into a purely military vessel, even if this is to the detriment of research or other non-combat capabilities. Entire fleets and indeed entire civilizations could fall before the guns of the Yamato-class. There are only four ships of this class operating in Starfleet, and just the threat that Starfleet has designed one is sometimes enough to prevent aggression. The ship is difficult to build and operate, and so is seldom seen outside of war zones. Indeed, it is seldom suited for anything but combat. While fairly effective flying solo, the Yamato-class is devastating when operating as the center of a battle fleet. Like all new purely military vessels of Starfleet, the ship's warp nacelles have been brought inboard to a minimum safe distance for field EM, and all EPS weapon-power conduits have been truncated to provide a nearly zero lag time between activation signal and beam launch.

The Yamato-class is also fitted with bio-neural gel pack computer interfaces and circuitry that enable high speed information transfers and the newest sensor equipment with efficiency levels that exceed that of the Galaxy class by 100%.

The Yamato-class likewise supports triple computer cores and a twin type-D trelinium/dilithium hybrid reactor. The Yamato-class supports 1,800 Starfleet personnel, but could also support a company of 200 Marines commanded by a Marine Captain, increasing the ship's capacity to 2,000.

Weapon SystemsEdit

The ship's weapons systems consist of the most advanced phaser and torpedo systems available. Octo rapid-fire quantum torpedoes and enhanced pulse phasers enables the Yamato sufficient firepower to destroy large fixed targets in one pass.

TorpedoesEdit

The Yamato features sixteen (16) brand new 5-torpedo-burst torpedo launchers, capable of launching a 5-torpedo volley every 15 seconds with a payload of 250 transphasic torpedoes, 750 quantum torpedoes, and 1500 photon torpedoes; and eight (8) 3-torpedo, rapid-fire, self-replicating quantum torpedo turrets, which fire a volley of three consecutive torpedoes in .5 seconds, with a recharge time of 2.5 seconds.

The ship also boasts of twelve (12) standard 1-shot torpedo bays among her three sections. Six (6) of the torpedo bays are mounted in the large dorsal rollbar pod, and another six (6) are on the large underside rollbar pod, at three (3) forward and three (3) back.

The vessel is also outfitted with ten (10) micro-torpedo arrays that face directly out at five (5) each to port and starboard, with a complement of 18000 micro-quantum torpedoes, a unique feature in a Starfleet vessel. The micro-torpedoes arranged in a 'phalanx' array along the port and starboard sides of the ship allow an astoundingly high rate of fire (200 torpedoes/min. per tube), which makes for a truly polyvalent weapon system, one able to cripple starships and ward off wings of strike fighters, while letting her keep her eye on her primary target.

PhasersEdit

The Yamato-class is equipped with a battery of sixteen (16) Type-XIV phaser arrays scattered in strips all over the vessel, to ensure all firing arcs are covered. These have been improved since their debut on the Sovereign-class, including a 75% increase in beam output, a shorter firing time of .65 seconds, and a shorter recharge time of .2 seconds. The firing time was reduced to concentrate all beam energy to when the beam hits shield or hull, which exponentially increases overall efficiency and nearly doubles damage to shields.

She also sports sixteen (16) Type-XV pulse phaser cannons, four to fore (two dorsal and two ventral), four each to port and starboard, and two each mounted on the aft section of the dorsal and ventral rollbars, which have been similarly upgraded since their debut on the Defiant-class. They now fire 14 pulses per volley before a recharge of 1 second, and pulse density and energy have been doubled.

For heavy weaponry, two (2) photonic cannons, and six (6) Type X+ heavy phaser turrets have been mounted. The photonic cannons fire particle beams of a different nature to that of a nadion-based phaser. They have higher amperage and a higher electrical charge than phasers, and subsequently are more powerful, but are a great energy drain and require a rather lengthy recharge time of 20 seconds after firing for a duration of 1.2 seconds. The cumbersomely-named heavy phaser is a, well, cumbersome weapon. More powerful than a phaser, but with high recoil and short range, they are mounted on 360-degree turrets scattered around the vessel to ensure acceptable firing arcs. These weapons fire in bursts of .8 seconds and typically fire in 3-burst volleys, after which they recharge for 6 seconds.

Defensive systemsEdit

ShieldsEdit

The shield system of the Yamato-class is equal to that of the larger Invincible-class fleet carrier-heavy battleship hybrid and is therefore the most powerful found on any Starfleet ship; the design was modified just prior to installation in order to have regenerative features and to increase effectiveness against both high energy tractor beams and phased anti-muon (polaron) particles, measures clearly aimed at the Borg and Dominion respectively.

Under normal operation, the shield modulation frequencies are controlled by the ship's computer system, which continually evaluates incoming weapons fire and automatically re-modulates the shields to provide the most effective possible defense. It is thought that this system can also prevent beam-through by Borg transporter technology.

Hull PlatingEdit

The Yamato-class boasts of a hull that is made of overlapping and regenerative ablative hull armor that allows it to take many direct hits from enemy fire even with minimal shields. In addition, the class has been equipped with two separate armor generators that can deploy a thick layer made of ablative armor plating along the contours of the entire ship when activated. This can be done through the numerous armor emitters that are installed at different points on the ship's hulls. This coating covers the ship's phaser mounts, but torpedo launchers are not affected by it.

Other Defensive SystemsEdit

For further protection, all protected internal systems that require access to the vessel exterior are equipped with articulated or jettisonable hull plates, so that most of the familiar structures are hidden from view, including shuttlebay doors, docking ports, lifeboats, impulse vents, and consumables resupply connectors.

This triple redundancy feature of shields and armor on the Yamato-class allows it to effectively counter Borg and Dominion firepower. However, due to the huge energy needed to deploy both the shields and the generated armor coating at the same time, the Yamato can only use these simultaneously for a maximum of thirty (30) minutes. As a result, the shields and the generated armor coating are used alternately when the ship is in battle.

Tactical Fighter WingEdit

Yamato-class heavy battleships are outfitted with a full-fly through hangar on deck 14 from which seventy-two (72) Phantom-class Advanced Tactical Combat Shuttles could be launched and landed.

Combined with the torpedo and micro-torpedo launchers and phaser array’s standard on the Yamato-class, these give the battleship unequaled sublight combat capabilities and could stand toe-to-toe against any form of attack.

Flag FacilitiesEdit

Another special feature of the Yamato-class is the full flag facilities it was equipped with. Yamato-class starships are among the few types that serve as flagships of the mobile fleets and task forces in Starfleet.

A primary flag facility onboard is the Flag Bridge , which is found at the rear portion of the Main Bridge . The Flag Bridge is where coordination between task force elements and planning for task force operations are done. It is the nerve center of the task force or the fleet being led by the Yamato-class

Crew Support SystemsEdit

AccommodationsEdit

The Yamato-class has rather spartan crew accommodations, but with consideration for the extended period of time that the ship's missions take. With emphasis towards the tactical systems being the foremost priority in the vessel designers' minds, crew quarters aboard Yamato-class vessels are spartan when compared to other ships in the fleet. Enlisted personnel are provided with cabins that have four bunks, non-commissioned officers and junior commissioned officers are issued cabins with two bunks, and senior commissioned officers are given cabins with one bunk and a few additional amenities. Each crew cabin is equipped with one replicator port, one standard computer terminal, and a washroom with ultrasonic shower.

SickbayEdit

There are two sickbay facilities located onboard the Yamato-class. The primary facility is equipped with two intensive-care wards, Biohazard Support, Radiation Treatment Wards, a Surgical Ward, Critical Care, a Morgue, a Dental Care Office, a laboratory, and the Chief Medical Officer's office. The secondary facility has two dedicated surgery suites, a physical therapy facility, Isolation Suites, and a Null-Gravity Treatment Ward. The primary facility is located on the port side of the vessel and the secondary facility is located on the starboard side. Also pursuant to new Medical Protocols, all Primary Medical Facilities are equipped with holo-emitters for the usage of the Emergency Medical Hologram System.

Mess LoungesEdit

Ships of the Yamato-class lack any sort of recreational facilities, and the only place for informal gathering is the two mess hall areas. These mess halls are the social center of the ship. Unlike all the equipment and materials aboard the ship, the mess halls are large and each has a very relaxed and congenial air about it. Each mess hall has a battery of recreational games and assorted means of entertainment. At the head of the hall were open slots that served as dispensers for the replicators. The mass-use replicators are able to produce other food and non-alcoholic beverages with an extensive recipe listing from over two hundred worlds for the crew to enjoy in this relaxed social setting. A counter extends from the underside and is used for the placement of trays, mugs and eating utensils. Eating accommodations are provided by a slew of tables and chairs. In addition, the mess hall doubles as a makeshift meeting area that could be used to conduct crew briefings and mission profiles. A tall screen panel located on one of the walls can be used as a visual aid to display tactical graphics.

Holodecks & Other FacilitiesEdit

There are four (4) standard holodeck facilities, twenty (20) holosuites, two (2) phaser ranges, and two (2) weight rooms on the Yamato-class, more used for tactical, security and combat trainings than anything for recreation.

Science PackagesEdit

Astrometrics LabEdit

Astrometrics serves the functions of Stellar Cartography. Served directly by the auxiliary computer core, the Astrometrics Lab conceivably has the largest single processing potential of any single laboratory aboard ship.

Facilities include multiple multi-use consoles, control facilities, a large wraparound viewscreen and a centrally placed dais with holo emitter.

All information is directed to the bridge and can be displayed on any console or the main viewscreen. When under warp or staffed by demand, the Astrometrics Laboratory is manned by one supervising officer and as many as eight subordinates.

Science LabsEdit

Even though the emphasis on the Yamato-class is tactical engagements, the vessel is equipped with a modest amount of scientific research space - in keeping with the mandate of the Federation and Starfleet. There are fifteen (15) science labs on the Yamato-class; eight non-specific labs are easily modified for various scientific endeavors including Bio/Chem, and Physics tests and/or experiments – crews rotate often among these laboratories - and seven specific labs on Planetary Development, Geologic Studies, Languages/Archaeology, Biologics Laboratories, two more expansive and specialized labs that conduct Atmospheric Physics experiments, and one for the dangerous High-Energy Physics. The Chief Science Officer’s office is attached to this bank of labs.

Propulsion SystemsEdit

Redundant warp and impulse nacelles were designed so the Yamato-class can sustain heavy damage, and still maneuver.

Impulse DriveEdit

The Yamato-class impulse drive system is the most sophisticated model in production. The new retro-thrusters enable the vessel to maneuver as well as any starship one quarter its size.

Warp DriveEdit

Yamato-class starships are currently some of the fastest vessels in Starfleet. They have a standard cruise speed of Warp 7.5, a maximum cruise speed of Warp 9.85 and a top speed of Warp 9.995 sustainable for up to twelve (12) hours.

Quantum Slipstream DriveEdit

Also, the ship is equipped with a Quantum Slipstream Drive. The ship is allowed to use the Quantum Slipstream Drive to travel at superfast speeds only once every two weeks. These very high speed capabilities are intended to allow the ship to deploy as rapidly as possible to potential trouble spots.

The Yamato-class has an unsupported, self-serviceable range equal to the Galaxy-class exploration vessels that is required to operate effectively behind enemy lines.

Emergency Holographic ComplementEdit

This class has holo-emitters installed throughout the ship, allowing the ship's Emergency Holographic Complement to operate in all areas of the ship. There are a total of twenty-six (26) emergency holograms that are of seven (7) different functions installed on the Yamato-class:

Each hologram is supplied with a mobile emitter, reproductions of the original device that was used by the EMH of USS Voyager. This allows the hologram to perform missions outside the confines of the ship.

Command and Senior StaffEdit

Owing to their being task force flagships, Yamato class starships have Commanding Officers that have the rank of Rear Admiral (lower grade), while Executive Officers are of the rank of Captain and Second Officers, Third Officers, and Wing Commanders are full Commanders.

Auxiliary StarshipsEdit

Mounted on the aft dorsal portion of the ship, three Defiant-class Armored Escorts rest in recessed hatchways. These ships are deployed to serve as “companion” ships whenever the Yamato goes on solitary special missions. Each ship has an assigned detail from the Yamato's main crew.

Task Force Flagship RoleEdit

Yamato-class starships are designed to serve as flagships of the largest task force formations of Starfleet. As such, she is accompanied by fifty-four (54) combat oriented starships during task force formations. Yamato-class starships are also the only ships in Starfleet with a permanently attached escort complement of one Akira-class heavy cruiser, one Prometheus-class tactical assault cruiser, one Intrepid-class scout, two Steamrunner-class light cruisers, and two Saber-class frigates.

Vanguard CommandEdit

There are three Yamato-class Heavy Battleships assigned to the Vanguard Fleet, the USS Belligerent, the USS Paladin, and the USS Dauntless.

The USS Belligerent is the flagship of Task Force Belligerent, while her sister ship, the USS Paladin, is the flagship of Task Force Paladin. Another sister ship, the USS Dauntless, is the flagship of Task Force Dauntless.
