This is a ship I've been wanting to post as part of the timeline for ages spurred on by a request from Wrangler and with the generous help from Cosair_SG who has an aero program that corrects any of my errors and formats it nicely.
I think I got this originally from the forum (I think maybe the old CBT forum) but I can't remember if that's right or wrong. If I did I thank the original designer and I hope you like the changes I've made. If not I hope you enjoy the pride of the Draconis Combine fleet.

==Overview:==
The Yamato-class is, quite literally, a thing born of the Draconis Combine
Admiralty's nightmares. Beginning in 3051, the Order of the Five Pillars (O5P)
was ordered to gather intelligence regarding the capabilities of the Clans'
most powerful Battleships. Because the Draconis Combine itself was being
assaulted by the Smoke Jaguar and Ghost Bear Clans, their attention
naturally fixed on the two most powerful ships in those Clans' Fleets: Clan
Ghost Bear's Nightlord-Class Ursa Major, and a Smoke Jaguar ship that O5P
believed was of the same class (actually this vessel is now believed to be
the Texas-class Smoke Jaguar).
The information gathered by O5P was sketchy, wildly inaccurate, and often
based on worst-case scenarios rather than real observation, with the result
that the vessel to be constructed by Project Yamato would be far more
powerful than the Clan Battleships it was meant to be copying.
Laid down in 3053, the Yamato-class Battleship would be delayed by
technical difficulty, bureaucratic meddling, and the basic inability of the DCA to
build a 1.5 megaton Battleship. One significant delay was even directly caused
by House Kurita's Internal Security Force (ISF,) which assassinated a senior
technician in 3057, halting work on the vessel's superstructure until a replacement
could be trained.
An entire shipbuilding industry grew around the massive vessel, converting
New Samarkand into one of the Inner Sphere's finest warship yards, but as the
vessel suffered setback after setback, the date became 3059, then 3060, then
3061. The vessel was launched in 3063. Christened the DCA Musashi, it was so
plagued with technical difficulties that its shakedown cruise was cut short at
three months - in that time, the crew had reported over one thousand-two
hundred technical issues, and over forty crew members had been killed, including
the vessel's captain.
With all these problems funding for the project was cancelled and the vessel was
put into mothballs. Every attempt by the DCA to revive the project was rebuffed by
the Coordinator until after the Jade Falcon War of 3067. With the Clans beginning
to strain against the Occupation Zone borders the DCA noticed that they would need
a WarShip capable of putting up a fight against the Clan Battleships. Beginning in
3068, Wolf Dragoon technicians were brought in to examine the Yamato's systems,
and they corrected many significant faults, but when the vessel was launched on
another abortive shakedown cruise in 3071, it was discovered that the might Musashi's
power grid was unable to simultaneously accommodate its main weapons battery,
main drive, and sensor systems. In fact, only one could be used at a time. Again with
Dragoon help the remaining technical issues were quickly resolved and DCS Musashi
entered service in 3073. Musashi would be followed by Nagato (3077) and the
Matsu (3081).
==Capabilities:==
Designed to compete with a class of ships that never existed, the Yamato, when
finally completed, easily outstripped both of its parent designs in terms of both
armour and armament. Yamato more armour than the Nightlord, with reinforced
broadside plate like a Texas. It also manages to pack a more potent version of
both vessels armament into what is essentially an enlarged Nightlord frame.
The most numerous weapons on the Yamato-class are thirty-six 55cm Naval
Laser Cannons, both arrayed along its broadside and scattered forward and with
a concentration aft, they provide a level of firepower rarely seen in naval-laser
systems. eight class-30 Naval Autocannons provide Yamato's aft protection.
Additional fire-support is provided by twenty four heavy naval particle projection
cannons, turreted forward and aft of the vessel's broadside and eight Heavy
Naval Gauss Cannons split into four paired mounts provide considerable forward
firepower. Twelve AR-10 launchers provide versatile missile support in the fore-arcs
and make for devastating extreme range assaults and fighter defence, they are
also fully capable of deploying the Combine‘s nuclear arsenal only to be used in
case of complete collapse in the face of an enemy.
Originally the ship carried only light anti-fighter and missile defence, however this
was upgraded during the 3068-3071 overhaul. In late 3067 one final defensive
measure was added eight Davion-designed, and reverse engineered, Screen Launchers
- these screens are spread around the vessel providing the vessel with defences
against naval class weapons making targeting the Yamato harder for enemy gunners
buying the Yamato‘s own gunners to kill their target. Twenty-six Combine-built
Heavy PPCs and twenty AMS cannons provide a capable defence against hostile
missile systems and a nasty surprise for incoming enemy fighters.
In terms of auxiliary craft, the Yamato Project vessels are adequately fitted, carrying
a full DCA Aerospace Fighter wing, six small craft, and six DropShips normally assault
ships or fighter carriers as the Yamato is designed to lead an attack force and eliminate
enemy naval assets. A lithium-fusion battery provides standard strategic mobility for a
vessel of this size. For internal defence the Yamato carries seventy-two battle armoured
marines, these troops can also be deployed via the use of the vessels many small craft,
DropShips or on their own for assaults against enemy vessels stupid enough to close on
the one and a half million ton vessel. In 3074 the vessel was upgraded with a Naval
Command-Communication-and-Control Net similar to that of the Omi Kurita-class
Super-Carrier making the vessels even more effective when working together.
==Notable Vessels & Crews:==
DCA Musashi
This vessel was the first vessel launched Yamato and was rushed into production
a year earlier than originally planned just in time for Coordinator-Regent Minoru Kurita’s
assaults against the Star Adder Occupation Zone. The Musashi was directed to
attack and disable or destroy the Star Adder’s Nightlord-class Absolute Truth.
Although they failed to destroy the vessel they did drive it from the Inner Sphere following
a battle in the Turtle Bay system. The Musashi was however heavily damaged in the
battle and would return to New Samarkand for several months of refit following the battle.
DCA Nagato
DCA Matsu
==Deployment==
With the Rasalhague Dominion and Snow Ravens on either border and both fielding massive
Leviathan, Nightlord-class and McKenna-class Battleships, and the Federated Suns on the
other border with the First Prince and Columbia-class Battleships, the Yamato type vessels
rarely keep a constant station. Instead showing the flag in the Combine's most remote
systems and on their most hostile borders warning any enemy that if they tested the Combine
borders they would have to pay a considerable price. Maintaining the three operational Yamato
class vessels rule out any attempt to build any more.
3075 EDIT: Initial intelligence about this capacity appears to be wrong with the emergence of the
Omi Kurita-class Carriers which was based directly off this hull design. As there are three such
vessels in service or under production Combine capacities were obviously underestimated.
