So if you saw my post on Combat Vehicles on a Royal Patton for Second Star League, you know about how Second Star League exists much earlier in the AU me any my friends are making and since tech in our AU is a bit different (WarShips aren't fully LosTech, they were just way too expensive an investment for the latter Succession Wars and too slow to build during wartime), I decided why not put this one out there because it isn't an SLDF without some badass battlewaggons.
So, after ComStar handed over control of Terra to the Second Star League, they also handed over the control of the preserved shipyards of the Sol System and to honor the formation of the new league and remind the other Successor States who's boss, the necant SLDFN orders, on request from the First Lord, the Construction of the first true WarShip in Generations in the Inner Sphere.
Their request was to build a single Battleship the likes of which had not been seen in centuries, a monster that would serve as the flagship of the Second League, the personal ship of the First Lord, and a monument to the return of peace and order in the Inner Sphere. The Specifications were equally ambitious.
They called for a front line Battleship massing between 1 and 2 million tons, with firepower equal or superior to a Texas or McKenna (it did not stipulate any specific type of weaponry needed but recovered stockpiles of Naval Weaponry mean they have more than enough of everything they might want short of Mass Drivers), 6 DropShip Collars to carry a full Regiment in Battalion Scale Transports or an entire escort group of Assault DropShips, and (since this is the HQ of the SLDFN and sometimes the personal vessel of the First Lord) mount as much protection as possible.
Recovered ComStar stocks mean that this thing can be built with at least mostly First Star League era components and technology.
This ship was ordered in the 3040s, but launched in 3057 due to the Clan Invasion and overruns in engineering.
The Project hasn't been given a name, but it is requesting a regal or majestic name.
