Anyways this is UNSCS Flight of Eagles, capital ship of Battlegroup Bird in Halo: Infestation. My animated comic series.

The planet behind it is HGCP-33 and its satellite Konos.
HGCP-33 is the closest planet to Arctic IV so this is some what a scene in IofI (IofI) is abbreviation for Infiltration of the Infestation or Escape the Infestation.

Flight is pretty much near its end, one of the last Halcyon battle cruisers soon to be replaced by the Marathon Class.
Flight began its service in 2517 and it ended 2554 after the Arctic IV incident.

Flight usually was the home of SPARTAN 2.5 program spartans. She and Talons of Falcons' her sister ship took on many covenant fleets. But after Arctic IV, Flight was in need of a few repairs but she was decommissioned as Talons of Falcons' was lost as it crashed on Arctic IV.
