An unnamed Fleet under command of Fleet Admiral Harper. During the First Battle of Earth on October 20th, 2552, Harper commanded his fleet directly into the Covenant foced, whilst the UNSC Home Fleet policed the skies.
Shortly after the Covenant arrival, the Fleet was split into two groups.
- First Echelon was controled by Harper and was in charge of destroying the CCS-class Battlecruisers
- Second Echelon was charged in stopping the Assault Carriers.
The amount of ships is not certain, howether, 2 Marathon-class Cruisers and 6 Frigates appear inside the circle (pictured, on left). A group of Longsword-class fighters are also present.
