Production notes
The Providence is a frigate classification featured in several pieces of concept artwork produced during the development of Halo 3. It is one of two such ships heavily featured alongside, and appears to have been an in-production stand-in for what would become the Charon-class light frigate in the final game. Two pieces of art featuring the Providence in combat are featured in the Halo Encyclopedia (2009 edition) and its 2011 reprint. The first depicts the ship alongside another, unnamed Charon-class, in naval combat with three s over a planet while the second shows the ship in a similar combat scenario but hit by enemy weaponry and on fire.

The Providence's feature in the encyclopedias, alongside its hull classification symbol having no other canon usage, indicates it may have some element of canonicity - though it has yet to be depicted in any Halo media outside of these features.
