Hospital ship

Hospital ships are a type of medical spacecraft and support ship employed by the UNSC and Covenant in wartime to transport and aid wounded personnel.

UNSC
The most famous UNSC hospital ship was the, a massive medical research facility and mobile hospital made of two refit stations welded together. It was considered legendary throughout the UNSC and virtually always on the move. The Hopeful was the site of the SPARTAN-III augmentation procedures. A similar station, Medical Facility Endurance, was used to administer the SPARTAN-II augmentations.

Covenant
The Covenant also made use of hospital ships, which are used to provide medical support to the fleet's entire complement of personnel. After several days of observing the Covenant's logistics fleet, John-117 still found it difficult to distinguish the Covenant's hospital ships from their munitions carriers and equipment freighters.
