The MCRN Donnager was the flagship of the Martian Congressional Republic Navy's Jupiter fleet. The Donnager is the namesake of the Donnager-class.


MCRN Donnager was a large battleship, almost 500 meters long and weighing approximately 250 000 tons.

Square and blocky, with small bulbous projections in seemingly random places, and designed for long periods at high-g, it was built in the "office tower" configuration: each deck one floor of the building, ladders or elevators running down the axis. Constant thrust took the place of gravity. At nearly five hundred meters long, it was the size of a 130-story building.

She was driven by four main engines and was painted in the MCRN colors of black and orange.

Armament Edit

  • Six Torpedo Launchers: Fixed missile silos capable of firing torpedoes with plasma warheads.
  • PDCs (Point Defense Cannons) positioned all along the ship's hull for defense against incoming missiles and close range enemy vessels.
  • Two Rail Guns firing 2-pound metal slugs at high speeds. Used in CQB (Close Quarters Battle) as were ineffective at long ranges[2].
  • Support ships: An internal hangar bay is used to hold support ships such as Patrol Destroyers and Frigates. At the time of her destruction, only the damaged Knight shuttle and MCRN Tachi were docked here.


At one time Bobbie Draper's MMC unit was attached to the Donnager.

Operation Silent Wall Edit

Operation Silent Wall was an MCRN operation to help safeguard terraforming materials bound for Mars. The operation would be lead by Theresa Yao and the Donnager. The operation would take 3 years and would be a success. This would be the first operation after the Martian Fleet Modernization program.

Eros IncidentEdit

After losing contact with Phoebe Station, Donnager was dispatched to find out what had happened to the facility and its inhabitants. When it arrived, it found everyone dead, their bodies having been incinerated, and that all the computer cores were destroyed.

Rescue Edit

The Donnager later picked up James Holden, Shed Garvey, Alex Kamal, Naomi Nagata, and Amos Burton from aboard the damaged Knight shuttle. Captain Yao had the group detained and interrogated. Since Holden had set out a broadcast blaming the Martians for the Canterbury, the already tense relationship between the UN and Mars was on the verge of boiling over into all-out war. Yao and Lopez, the ship's intelligence officer, tried to convince Holden to recant his claim, but he refused.

Final Battle Edit

Whilst Holden and his crew are in their quarters the Donnager comes under attack from the 6 presumed Belter ships that had been trailing the Knight shuttle.

Lieutenant Kelly along with his marines then released the surviving Canterbury crew and escorted them to the hangar to reach the Tachi. Whilst Marine Gomez provided cover fire.

Although Kelly is wounded however managed to board the Tachi; ordering Alex Kamal a former Martian Congressional Republic Navy pilot to fly the ship out of the Donnager. The Tachi escapes in a high-G burn however Lieutenant Kelly wounded is crushed to death inside of his armor.

Suddenly, an incoming ship was detected heading towards Donnager at full burn. The ship could not be identified, but Captain Yao assumed it was just another OPA belter ship. However, upon arrival, it was revealed to be not one, but six mysterious craft linked together. Breaking apart, they jammed the Donnager's communications and moved in to attack, firing eleven plasma torpedoes. The call to battle was sounded, and the Donnager fired back with twenty torpedoes, destroying one ship. While her PDCs shot down most of the enemy's torpedoes, one missile got through, damaging the Donnager's reactor and melting a huge hole in the ship's rear.

The five remaining attackers entered the minimum range for missiles, and Donnager powered up her two Railgun turrets, taking out two attackers. Concentrated fire from the PDCs destroyed one more. Much to the surprise of the command crew, the "bandits" fired back with their own Railguns, pounding the Donnager until she was forced to shut down her damaged drive. Her pummeled defenses now offline and venting atmosphere, the remaining attackers launched boarding pods and unknown combatants swarmed into the ship.

Holden, having realized that the attacking ships are identical to the Canterbury's killer and that these unknowns were trying to set the Martians up, is sent to be evacuated by Lopez and some Martian Marines along with data on the attacking ships. The other Canterbury survivors are rescued, at which point Lopez receives word that Yao has set "condition zero"; Donnager is going to self-destruct.

The Marines and Canterbury crew make their way to the hangar where MCRN Tachi, a Martian missile corvette, is docked, but the hangar is swarmed with enemy boarders. The Martian Marines are killed, Lopez is fatally wounded, and Amos is shot in the leg, but Alex takes control of the Tachi and, using the corvette's PDCs, blast their way free of the ship and escape.

Destruction Edit

Back on the Donnager, enemy boarders attempt to breach Donnager's CIC, but Yao activates the self-destruct mechanism, vaporizing the Donnager and everyone left on it. MCRN Donnager, the pride of the Martian Navy, was no more.

Trivia Edit

  • Donnager virtually means "Thunderer". The cognate deity in wider Germanic mythology and paganism was known in Old English as Þunor and in Old High German as Donar (runic þonar , stemming from a Common Germanic *Þunraz (meaning "thunder").
