Halcyon-class light cruiser

Summary
The UNSC Halcyon-class cruisers were designed by Dr. Robert McLees in 2510, and served only a short while because their unique hull design was considered too costly and risky to use, as well as being too slow. They were subsequently replaced by the Marathon-Class cruisers. Their only noteworthy design feature was a series of cross bracings and honeycombs that made the ships virtually indestructible. They can be operational after sustaining breaches to all compartments and losing 90% of their armor.

They were the smallest vessel to recieve the cruiser designation. They are only one third the tonnage of the Marathon class cruisers currently in service. Their Mark II fusion engines supply a tenth of the power of modern reactors.

Some, however, were later pulled from long term storage after the Covenant War broke out. According to Covenant computers, the Halcyon-class cruiser is listed as a 'Human attack ship type C-11'.
