The Capital Ship Project was created by the four nations of the Novus Orsa star cluster as a means to increase the security of the core or capital worlds of each of the nations. However, the real reason for their development was to be used against the Evoans should they ever reopen the wormhole to the Milky Way Galaxy, a secret only the leaders of the four nations and a few select others know. The request by the leaders of the four nations to their military leaders and engineers was to design specific capital ships, such as dreadnoughts, carriers, and supercarriers, the last of which would serve as a flagship for the main fleet.
At the time of the discussions, though, the Improbus Dominion was already at work designing a larger dreadnought in its mission to conquer the star cluster prior to the peace agreements. However, the problem at the time with the design was the size and practicality as the ship’s hull would be too big to fit through star gates. The ship would have to rely on the outdated fold drive to traverse the star cluster. They also had not designed the weapons system of the ship yet, however once the four nations began to design the ships and weapons, some of the companies that designed the weapons sold them to the Dominion to include with their design. As a result, the Dominion was the first to complete their dreadnought design, christening it the Typhoon. This sent waves through the cluster as the other nations now had to catch up. The one thing that all the dreadnoughts shares in common is the number of capital ship weapons and the reasons for that number. The nations made the size limit of the dreadnoughts at 3.5 kilometers due to the size of the guns. However, due to the size of the ammo and/or capacitors as well as the jump drive installed, the ship can only house six weapons, usually mounted in pairs to make things simpler. This means it lacks the firepower to target and take out smaller targets, a trait all the dreadnoughts share. This means that they need to be accompanied by smaller ships and/or carriers. Much like the other dreadnoughts, many components were “upscale” to make the design and construction of the ships quicker and cost effective. This is why there are similarities between ship parts with the smaller ships.
Much to the surprise of the militaries of the four nations, the Novus Orsa Republic was the last of the four nations to design a dreadnought but the reason for this is valid. To stick with the idea of upscaling parts and components while keeping with the current design philosophy of the current ships proved more difficult when designing the dreadnought with the weapons that the ship would be using. After a long while, the design was finally put forth that kept with the size and weapons limit set forth per the agreement. Called the Mammoth (again a type of dragon in keeping with the current naming convention at the moment), the dreadnought was the widest of the four dreadnoughts designed but still kept the length at 3.5 kilometers. The weapons were also in an odd placement and configuration compared to the other dreadnoughts as well. The Mammoth mounted 4 weapons above and 2 below but the weapons that the Mammoth uses are different from the other dreadnoughts. 2 of the weapons are missile launchers and are mounted above and to the back. Because of the nature of the launchers, they can fire the missiles which can move away from the ship and fly around to hit their target. The most unique set of weapons on the Mammoth are located on the other 4 mounts located on top and towards the front as well as below. Based on the modules found on smaller ships, the Mammoth now mounts 4 graviton beam cannons, the first ship to use that cannon as a turret. Seeing the use of graviton beams against other ships as being effective, the Republic wanted to use the same weapon on the Mammoth without violating the agreement and mounting them within the hull similar to sub-capital ships. In keeping with the agreement, the Republic will only be building 8 of these ships to protect the capital and other core worlds of the Republic.
