"Space-borne guided missile cruisers are currently a idea that will hopefully replace all other cruiser classes. Every cruiser built prior to the Marathon-class will be scrapped, save for the Halcyon cruisers, and the things that it is armed with are one of two."
Then-Fleet Admiral Nikolai P. Sherman on guided missile cruisers, c. 2526.
UNSC guided missile cruisers have become the backbone of the United Nations Space Command Navy since the introduction of the Marathon-class back in 2515. The new Autumn-class guided missile cruisers has been seen as the legacy of the Pillar of Autumn (C-709), was introduced in 2554 as the successor to the Marathon-class, replacing it on a three-to-one basis. Guided missile cruisers are named after famous ships, locations, and battles.

Stealth cruiser (CS): A concept born during the fires of The Great War, stealth cruisers are the biggest ships in the Prowler Corps' arsenal. Only two classes have been in service as of 2558.
•No Return-class: 3 completed (first class of stealth cruisers in service)
•Vulture-class: 7 completed, 3 undergoing trials, 8 under construction, 4 more planned (second class of stealth cruisers in service)
A/N: I am also including ships from Halo: Reclaimers, The Life, the Eon and Strike Blade series, The Reclamation Has Begun (old and reboot), Halo: Rise of the Empire and other Halo-related stories as well as some from Halo Fanon so the credit goes to them. The remaining Marathon-class cruisers (that weren't turned into museums, scrapped, or destroyed) received refits and were then transferred to the UNSC Colonial Guard or in the case of the UNSC Helios, a mobile command center for ONI SPECTRE Division. By the way, I wanted it seem that the UNSC had updated it's ship classification system similar to 'real world' standards, considering the secondary offensive weapons were it's missile pods. The UNSC Midway was a Halcyon-class cruiser, a part of UNSC Task Force X-Ray, that was destroyed over Harvest during the Liberation of Harvest. Marathon-class cruisers are however still produced, just delivered to the UNSC Colonial Guard.
The UNSC Navy's Task Force Dakota is essentially Battlegroup Dakota, I just think that Task Force would be a more fitting title because it's bigger than an actual battlegroup, it consists of the best ships and crews within the Navy. Task Force Dakota's duties is the protection of the UNSC Infinity, the defense of Earth and Her Colonies, and joint operations with the Swords of Sangheilos. Dakota is current under the banner 3rd Fleet, making it the strongest formation within 'Cole's Stubborn Third'. Like the nickname? It was thought by Just-a-Crazy-Man, so give him the credit for it.
TF-Dakota is made up of the Infinity herself, two Epoch-class supercarriers, about nine carriers of varying classes, three Vindication-class battleships (Dakota will be soon joined by several battlecruisers in the future), over a dozen or so Autumn-class cruisers (which will increase over time), fifty-six Halberd-class destroyers (which will be gradually replaced with the newer Midlothian-class guided missile destroyers), eighty frigates of varying classes (they will also be replaced gradually by the new Remembrance-class frigate), sixty-five Strident-class littoral combat vessels (ten of which are stored within the Infinity's sub-vessel hangers), a dozen assault ships, and twelve prowlers.
The UNSC Unto the Breach is a Autumn-class cruiser mentioned in Hunt the Truth by Benjamin Giruad (who is possibly incarcerated now) which is the flagship of Vice Admiral Gabriella Dvørak, an officer in the Naval Intelligence, who had allegedly 'met' John-117, but it was all a lie to keep Ben off the trail of the flash-clones put into the place of the SII.
