Though smaller than its Martian counterpart at only 376 meters in length and not as sleek nor as sophisticated, the Truman-class is famed for its sturdiness and reliability and is one of the longest-serving vessels in the history of the UNN, having protected Earth's interests across the system for decades.
The Truman-class dreadnought is armed with 2 Farren-Pattern high-yield heavy railgun turrets, 9 autoloading torpedo bays that are compatible with a variety of warheads, and 42 Redfield Ballistics 40mm point defense cannons (PDCs) spread across the surface of the dreadnought for maximum defensive coverage. The effective targeting range of the Truman-class is shorter than that of most MCRN warships but its extensive PDC grid enables it to endure even the largest torpedo volleys, protecting the ship from harm while coordinating fleet movements or bringing her railguns to bear.
A pair of hangar bays and accompanying external docking clamps are located in the midsection of the Truman-class, where its complement of 6 L-Type UNN dropship skiffs, as well as a smaller number of short-range repair skiffs and reconnaissance drones are housed. Though the Truman-class is not quite large enough to carry corvettes in its internal hangars like the MCRN's Donnager-class battleships, its embarked dropships widen its mission profile to include Marine deployment and surface reconnaissance.
The Truman-class dreadnought contains many various facilities within for a warship this size. Some of them include:
- Advanced Medical Facilities.
- Comfortable Living Quarters.
- Extensive Cargo Space.
- Dropship Loading and Repair Facilities.
- Standard Tightbeam Communications Systems.
At the time of the Ganymede Incident, the Truman-class dreadnought had been in service with the UNN for decades and served as the flagships of high-ranking admirals, such as Admiral Augusto Nguyễn's UNN Agatha King and Admiral Souther's UNN Okimbo.
The Agatha King notably participated in the Io Campaign as part of a rogue element of the UN Navy commanded by Nguyễn where they engaged a MCRN fleet as well as the UNN's Jupiter Fleet under the command of Souther which included the Okimbo and two other Truman-class dreadnoughts. The Agatha King was later scuttled by the crew of the Rocinante after being inadvertantly struck by an out-of-control Protomolecule Hybrid Pod, leading to the Protomolecule infecting and killing most of her crew.
At the time of the war between Earth and Mars that broke out following the Ganymede Incident, the Truman-class dreadnought was one of the longest-serving vessels in the history of the UNN, having been protecting Earth's interests across the system for decades and serving as the immovable center of UNN battlegroups. The UNN Agatha King (T-DRN-32) served as the flagship of the UNN's Jupiter Fleet under the command of Admiral Souther until he was relieved of command by Fleet Admiral Augusto Nguyễn who ordered the dreadnought to for Io to retrieve Jules-Pierre Mao's Protomolecule hybrids.
When several UNN warships refused to obey Nguyễn's orders following a failed mutiny initiated by Souther against Nguyễn for waging an illegal war, the Fleet Admiral declared them deserters and destroyed one of the ships, the Jimenez, with a torpedo from the Agatha King which prompted other UNN ships loyal to Souther to fire on the Agatha King in retaliation. However, their torpedoes were shot down by the Agatha King's PDCs and the UNN dreadnought proceeded to destroy several more UNN warships in retribution. The Agatha King was later hulled by a hybrid pod that was hit by PDC fire from an MCRN warship over Io after Nguyễn initiated a mass launch from the moon's surface targeting Mars and the UNN dreadnought and her crew subsequently became infected by the Protomolecule. The Agatha King was later scuttled after an infected Cotyar Ghazi intentionally destabilized the ship's reactor.
Several months later, the Truman-class dreadnought UNN Thomas Prince (T-DRN-47) carried various religious clergy and artists including Annushka Volovodov into the Ring. The Thomas Prince was one of the ships in the Slow Zone to be suddenly stopped by the Ring Station, leading to serious casualties at the start of the Slow Zone Incident with Commander Kunis assuming command as the highest ranking officer amongst the surviving crew. After the crew of the Rocinante broadcast that all of the ships in the flotilla needed to shut down their fusion reactors to convince the Ring Station that humanity was not a threat and release their ships, the Thomas Prince was the first ship to do so under Kunis's orders at the insistence of Dr. Kolvoord. Afterwards the Thomas Prince returned to Earth's solar system through the Ring alongside the rest of the flotilla.

- Dreadnought is a an English phrase which means fear nothing. It was a type of heavily armoured, heavily armed, slow battleship built before WWII. Dreadnoughts were built with the aim that they should withstand hits from at least the same gun caliber as they were carrying.
- The Truman-class dreadnought is likely named after Harry S. Truman, 33rd President of the United States, who was the first world leader to sign the United Nations Charter and as of 2018, was the only person to have authorized the use of nuclear weapons in warfare.
