Donnager-class

The Donnager-class battleship is a class of modern Martian Congressional Republic Navy battleship. Donnager-class battleships are almost 500 meters long, about the same size as a 130-story office building. Measuring 250,000 tons dry weight, pound-for-pound Donnager-class battleships are some of the largest and most capable ships in the Martian Congressional Republic Navy. As the primary mainstay battleship classification in the MCRN, the Donnager-class serves multiple roles throughout the Sol System. Like all other MCRN ships, Donnager-class battleships are built at the MCRN Callisto Shipyards. However, because of the importance and investment in designing and constructing each Donnager they are incredibly difficult to make, and only eight of them were constructed during the UN-MCRCold War. Currently all eight Donnager-class vessels exist in the Solar System, serving in a variety of roles including fleet command and coordination, battleship, force projection, and carrier of gunships and infantry.
The Donnager-class battleships are among the largest and most efficiently built ships in the Martian Congressional Republic Navy and are the pinnacle of the fleet. These massive ships are a bit smaller than the Xerxes-class, their counterparts in the United Nations Navy, but make up for it with a thick hull that allows them to take multiple hard hits. In addition, their 40mm Point Defense Cannons are controlled by high-accuracy point defense targeting computers—one of the MCRNs most treasured systems for its advanced tracking and targeting algorithms. These battleships are what makes the MCRN standout and were designed as the pinnacle of forward-thinking technology so that each ship could hit harder and faster, and that’s never been truer than with the Donnager-class battleships.
MCRN engineers had the foresight to equip the Donnager-class with four Railgun hardpoints on the hull, giving it the option to double the rail guns should such upgrades become available in the future, guaranteeing its continued technological superiority and keeping it from becoming obsolete so quickly. On top of the ultra-heavy rail guns, the Donnager-class battleship also hosts a hangar bay large enough to home their own protective escorts; in addition, it maintains a number of Dropships and Gleason-Type repair skiffs that allow the MCRN to repair their own ships without docking or returning to a shipyard. These designs and tech secrets are so ferociously protected that if one is boarded, a biometrically-activated self-destruct mechanism triggers to prevent them from being captured and replicated or used against the MCRN.
The design and construction of the MCRN fleet are so advanced and well-planned that they rarely have any flaws or any sort of problem with their ships. Even though the Donnager-class is smaller than the average battleship, they have a larger crew compliment than their UNN equivalents.

Complement

The Donnager-class is capable of hosting a crew complement of 2086 personnel, including squads of Martian Marine Corps and their elite Force Recon units, equipped with Goliath Power Armor. Thanks to the ship's interior hangar bay, located near the aft of the huge vessel, the Donnager-class can host its own escort ships in six interior ship berths. Each berth can hold one Corvette-class frigate or two Morrigan-class destroyers. The battleship additionally hosts a number of Troika-class Dropships, Gleason-type repair skiffs and - depending on deployment - executive shuttlecraft.

Armament

The most notable elements of the Donnager-class' weapons complement are its two dorsal VX-12 "Forehammer" Turreted Ultra-Heavy Railguns. At the time of the class' construction, these weapons were amongst the highest-spec railguns in the Solar System and only matched by The UNN's Orbital weapons systems. Thanks to the foresight of MCRN engineers the Donnager-class hosts a total of four railgun mounts on its hull, capable of doubling the ship's railgun complement should such technological advancements allowing such an upgrade become available.
The Donnager-class' other main weapons are it's six fore and eight aft rapid-reload missile launchers, capable of attacking vessels in front of and behind the vessel. These launchers are linked to shared magazines of high-explosive (HE), plasma, flechette, and nuclear warheads. For defense, the Donnager-class employs fifty-nine Nariman Dynamics 40mm PDCs, linked to the K-19 "Banisher" High-Accuracy Point Defense Targeting Computer, the most advanced target tracking system employed by the MCRN. Aside from its primary armaments, the Donnager-class serves as a capable command vessel in combat, with its ranging lasers and tactical systems to help guide and coordinate the efforts of fleet elements against hostile ships. In the event that a Donnager is boarded by hostiles, Donnagers are equipped with a biometrically-activated to self-destruct mechanism that ensures the ship cannot fall into enemy hands.

MMC Crew

The Donnager-class is the apex battleship in the galaxy and the MCRN knows it, assigning only the best-of-the-best to to crew it. Those assigned to a Donnager-class are the most elite of the Martian Marine Corps, including members of the Infantry, Armor, and Force Recon branches; Goliath powered armor is kept on board in addition the standard Martian light armor. In particular, the captains of Donnager-class battleships are the most brilliant and skilled captains the MCRN has to offer and are often in charge of over 2,000 crew members. The MCRN rewards their crew with an on-board MMC barracks and armory, as well as a sophisticated medlab, all considered cutting edge technology and a part of what make an MCRN vessel worth more than its UNN counterpart.
