PRO-49776

This unnamed stealth ship designated ONI PRO-49776 was a specialized vessel used by the Office of Naval Intelligence and captained by Lucius R. Jiron.

Operational history
The ship was sent by the ONI to retrieve a high-priority "package" from a Covenant fleet trapped in a stellar magnetic field that prevented them from jumping into Slipspace. Onboard, there were five SPARTAN-IIs who were eventually sent out to retrieve it using OF92-EVA Booster Frames stored onboard the stealth ship. After the Spartans successfully retrieved the package and the Covenant fleet jumped away, the stealth ship de-cloaked and destroyed the remaining Seraph-class starfighters. After picking the Spartans up, the ship re-cloaked and jumped away.

Complement
The ship had a ventral launch bay fitted with hook systems used to deploy OF92-EVA Booster Frames. Instead of using photoreactive panels for stealth like the Prowlers, this ship utilized a more advanced, bubble-like cloaking field projected around it to conceal it from view. It also utilized a type of advanced directed energy weaponry, capable of dispatching Covenant Seraphs with ease. These directed energy weapons are possibly Pulse Lasers.

Trivia

 * Despite the ship's stealth capabilities and the "PRO" classification in its registry number, Frank O'Connor has confirmed that the ship is not a prowler.
