2495 Fleet Expeditionary Frigate

In 2495, the United Nations Space Command launched a project to create a frigate model capable of transporting troops and supporting major deployment actions across UEG Space. This project, retroactively described as the 2495 Fleet Expeditionary Frigate, resulted in several unique ships and a number of classes of ships, ultimately including the indisputable "winner" of the program: the Aeolus-class light frigate. 
==Project results==
#(2496) Great Gustav City-class expeditionary frigates
#(2496) Enforcer-class light frigates
#(2497) Three Red Rivers-class expeditionary frigates
#(2498) Aeolus-class light expeditionary frigates
#(2499) 624 Hektor-class light carrier
#(2501) Gallant Galloper-class light frigate
#(2507) Heaven's Vanguard-class expeditionary cruiser
===Great Gustav City-class===
The Great Gustav City-class expeditionary frigate began entering service in 2496. The class emphasized armored compartments for equipment and personnel and featured thicker-than-normal armor plate, heavy point defenses, and a light coil main gun. While durable and well-defended, the Great Gustav City-class lacked the speed and mobility the Fleet desired for the new expeditionary frigate. Nevertheless, a dozen frigates were commissioned between 2496 and 2500.

===Enforcer-class===
The Enforcer-class light frigates began entering service in 2496. 
===Three Red Rivers-class===
The Three Red Rivers-class expeditionary frigates began entering service in 2497. 
*UNSC Argyre Industrial 
*UNSC Mons Agnes 
*UNSC Three Red Rivers 
===Aeolus-class===
The Aeolus-class light expeditionary frigates began entering service in 2498. 
===UNSC 624 Hektor===
The UNSC 624 Hektor was commissioned in 2499 as a light carrier. At 766 meters, the 624 Hektor was massively oversized for the parameters of the project and was rejected as a frigate. The fleet nevertheless accepted the unique ship as a carrier. 
===UNSC Gallant Galloper===
The UNSC Gallant Galloper was commissioned in 2501. Measuring 466 meters in length and sporting enormous engines, the Gallant Galloper was capable of corvette-approximate speeds while transporting a battalion's worth of troops and equipment and a frigate's worth of armaments. Comparable in expense to a heavy destroyer, the design was rejected for mass production or even a limited run, but the unique light frigate was accepted into the fleet. 
===UNSC Heaven's Vanguard===
The UNSC Heaven's Vanguard was commissioned in 2507. The 786-meter-long ship had spent more than a decade in development, far exceeded its allotted budget, and failed practically every qualifiable aspect of the project aside from expeditionary capacity. Much like the earlier 624 Hektor, the Heaven's Vanguard was "painfully obviously not a frigate by even the generously charitable measure" and languished for seven months before finally being accepted and commissioned into the fleet as a unique expeditionary cruiser.
