Naval Support Activity Castle Bravo (NSA Castle Bravo) was a UNSC Office of Naval Intelligence installation located in the polar regions of the planet Gliese 876 D (Bellerophon). Nominally a planet-side communications relay facility of the UNSC Navy, it instead was an expansive and highly-classified headquarters for a subsection of the Directorate of Strategic Intelligence, Naval Intelligence Office of Special Investigations.

The facility hosted a massive underground shipyard as well as an energy shield projector array similar to that employed by the Covenant during the Invasion of Reach. It was listed as an ONI alpha-class site that was a sister facility to the Alpha Site destroyed in New Mombasa, as well as to Naval Support Activity Esplanade on Midgard.

NSA Castle Bravo was named by Naval Intelligence officials after the original CASTLE Base, which was destroyed in 2552 during the Fall of Reach. Some of its predecessor's classified responsibilities were transferred to Castle Bravo.
