Project ARSENAL

Project: ARSENAL was a major naval design group that produced numerous warship classes for the United Nations Space Command (UNSC) from 2482 to 2553. Originally instituted under to Project: FORTRESS, the ARSENAL group was responsible for several critical designs that saw enormous action during the Human-Covenant War. 
==ARSENAL designs==
Design 	Launched	Notable details
JAGERJäger-class expeditionary cruiser 	24842484	The Jäger-class comprised seven expeditionary cruisers. Over a thousand meters long and sporting a small Magnetic Accelerator Cannon (MAC), anti-ship missiles, autocannons, and point defenses, the Jäger cruisers were well-armed while still having capacity for more than a regiment of troops and all their equipment. While the design was considered a success and produced seven capable expeditionary cruisers for the UNSC and CMA, the Jäger design did not meet with much fanfare or popularity at the time of their introduction.
BALLISTICIANBallistician-class light destroyer 	24872487	The Ballistician-class comprised six light destroyers. The first UNSC escort ships to carry the magnetic accelerator cannon, the Ballistician-class was a radical departure from contemporary designs: light armor plating with a reinforced internal framework, a small number of anti-ship missiles, a large reactor and oversized engines, and, of course, an unmatched main gun. The Ballistician destroyers also featured a small hanger for a pair of pelican dropships. The revolutionary design was not well-received at the time of its introduction and its limited production of six destroyers was accurately seen as a grudging bare minimum by a recalcitrant Admiralty. Historically, destroyers were missile ships with the understanding that they served in whatever role the fleet needed at the time; the Ballistician was a MAC-centric destroyer entirely focused on anti-ship operations and was thus an unwelcome addition to the fleet and was quickly sidelined. Many of the elements that made the class so poorly received were retained and reused in the subsequent development of the Gladius-class heavy corvette.
