Refit station

A UNSC refit station is essentially a large square plate of Titanium-A, square-shaped and measuring one kilometer by one kilometer. One refit station is capable of refitting six destroyers, three from her upper surface and three from her lower surface, in a matter of hours. As the fortunes of war against the Covenant worsened, the UNSC began to use such stations as shields for their Fleets in major battles. Four such stations were destroyed with all hands lost in the battles of Sigma Octanus IV and Reach, including the UNSC Cradle, which sacrificed itself to save the UNSC fleet at the Battle of Sigma Octanus IV from destruction.

A curious result of the destruction of these stations is the creation of a field of very fine Titanium-A dust particles which have exhibited an ability to disperse the plasma from Covenant weapons systems.

Trivia

 * The UNSC Hopeful was constructed from two scrapped refit stations.
 * Given its purpose and resemblance to the Hopeful, Anchor 9 is probably a refit station.
