Template:Ship The Halcyon-class Cruiser was a United Nations Space Command cruiser starship classification designed by Dr. Robert McLees in 2510. According to Covenant computers, the "Halcyon"-class cruiser was listed as a Human attack ship type C-II. Their service lives were short due to a unique hull design that was both costly to construct and maintain, lack of speed, and concerns about their tactical viability. They were subsequently replaced by the Marathon-class cruisers.

Features

At 1.17 kilometers in length and one-third the tonnage of the succeeding Marathon-class cruisers, the Halcyons were the smallest vessels to be designated as cruisers. Compared to modern ships the original Halcyons were sorely underpowered and under gunned; their Mark II fusion engines provided but a tenth of the output of modern reactors, and their armament consisted of a mere six Archer Missile pods, and a single MAC gun. The only noteworthy design feature was a series of internal cross bracings and honeycombs that made the ships surprisingly resistant to battle damage; ships of the class were able to remain operational despite sustaining breaches to all compartments and losing 90% of their armor.[1]

When the Human-Covenant War erupted in 2525 a number of Halcyons were reactivated from storage and extensively refitted with additional Titanium-A armor and dozens more Archer Missile pods. One such ship, the Pillar of Autumn, demonstrated the ability to launch over 1000 missiles at once.

Interior

Corridors on the Halcyon-class were segmented by several retractable containment bulkheads. In the event of an emergency these bulkheads could be closed and affected sections sealed from the remainder of the ship. A potential application of this was during a hostile boarding action, whereas the atmosphere in the sealed sections could be vented via commands from the bridge, asphyxiating enemy troops.

Armories were located located throughout the ship, holding a selection of small arms and their requisite ammunition. Eight docking bays allowed a number of Pelican dropships, Longsword Interceptors, Warthogs and Scorpion Tanks to be carried.

A number of service corridors ran the length of the ship. Although normally restricted to personnel, they could be accessed by lifts in main engineering or connecting passageways from the docking bays. If necessary these expansive corridors could permit passage to Warthogs and some sections were large enough to accept Pelicans. The corridors served a secondary purpose of lessening the ship's considerable mass, thereby increasing acceleration.

Compliment

Halcyons usually embarked a compliment of regular Marines, sometimes augmented by an ODST battalion. It has been speculated that a normal crew numbered 1200, including 400 naval personnel and 800 soldiers. Template:UNSC Ships

Miscellaneous

The length of the ship in kilometers is 1.17, another reference to not only the number 117 (others including John-117 or Spartan-117) but the number 7 in general.
