PRO-49776

The ship designated ONI PRO-49776 was a specialized stealth 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 fighters. After picking the Spartans up, the ship re-cloaked.

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 stated that the ship is not a prowler. However, prowlers depicted in The Mona Lisa motion comic, the comic Halo: Fall of Reach - Invasion and Halo 4 feature an unmistakably similar design. As the term "prowler" can refer to a variety of ships, including the stealth cruiser Point of No Return, it is likely that PRO-49776 is a specific type of prowler (possibly one designed intentionally for booster frame launch and recovery operations) other than the standard 162 meter long models.
