"The Gulf-class Cruisers were great ships. They were badass, and did better then a usual Cruiser in combat, even though they only sport 3 MACs, and a few batterys of mini-MACs. This is because they weren't a fucking mile long and 800 meters high, like the normal Cruisers of the day! But, for all their badassness, the class in its pre-late 2552 configuration just weren't capable of holding up to a plasma torp' in any circumstance...and then there was the fact that there was only one ship of the class still in service at the end of the friggin' Human-Covenant War."
―Anonymous UNSC Captain
The Gulf-class Light Cruiser was a experimental Light Cruiser that appeared out of Earth's Spaceworks only just in time for the First Battle of Earth.
The ship, created as a possible replacement to the huge Light Cruisers that, due to supply shortages, were no longer being made. The Gulf-class, as well as being quite agile compared to the much-larger Crusiers, also packed a powerful loadout for a ship of its size, comprising of 2 Heavy MAC Cannons, a MAC Cannon, 28 Mini-MAC Guns in 14 turrets stratigically located arounf the ship, and a pair of large-caliber Point-Defense Autoguns per side.
The Gulf-class Light Cruiser was first conceived as smaller capital ship, to replace the older (and much larger) Halcyon- and Marathon-class Cruisers. Following hours of meetings and countless design revisions by design engineers, the engineers finally yielded a blueprint to present to the UNSC Navy. Following a couple minor revisions, the Navy agreed to fund the construction of 3 Prototypes.
The first Gulf-class Cruiser, the namesake of the class, obviously, was the UNSC Gulf. During construction, due to a mistake in the hastily-drawn plans, supports in the ship, which were incapable of supporting the combined pressure of Air and simulated crew load, suffered a catastrophic structural failure. The Gulf was internally torn apart by the force of the gases escaping, and the Gulf was broken down for parts. The two surviving examples, UNSC Floyd and UNSC Las Vegas, were given amended structural modifications, completely alleviating the design flaw, and both ships entered service soon after.
Both the Las Vegas and the Floyd were overhauled just prior to the Battle of Earth, the first engagement the ship would serve in. When the Covenant attacked Earth on October 20, 2552, the Las Vegas and Floyd both engaged Covenant ships. Tragically, the UNSC Floyd was destroyed after numerous Plasma Torpedo hits, during the later stages of the fight.
The UNSC Las Vegas served valiantly through the rest of the war, as well as post-war, preventing any attacks to Earth in her weakened, post-war state.
