YSS-1000

The Saber is a space fighter operated by the UNSCDF to reinforce the UNSC Navy, should they require assistance in battle. Much like a space shuttle, the Saber can be launched vertically from a ground-based launch platform, and uses rockets to propel itself out of a planetary atmosphere.

SPARTAN-B312 of Noble Team used one of these vehicles to assist the Epsilon Eridani Defense Fleet during the Fall of Reach.
