UNSC Cradle

Summary
Cradle was a refit station capable of intersystem travel. Essentially a large square plate of Titanium-A, it was a square kilometer in diameter, and capable of refitting six destroyers, three from her upper surface and three from her lower surface, in a matter of hours.

In 2552, it was present at The Battle of Sigma Octanus IV. The ship was used as a shield for the fleet when the Covenant attacked, and it was sacrificed so that the humans could protect their ships from a salvo of plasma fire.
