Comberth Harbor is a major city and harbor on the Usean continent. During the Second Usean Continental War, Erusea deployed its "invincible" Aegir Fleet to Comberth in preparation for an invasion of North Point.[2]


Comberth is a massive harbor, encompassing multiple suburbs, industrial areas, and two large metropolitan areas connected by a bridge. The terrain surrounding the harbor area is completely flat. Comberth Harbor's naval facilities include submarine docks, numerous shipyards, and New Comberth Harbor, which contains ammunition and fuel storage, as well as several dry-dock facilities.[1]


Comberth Harbor was originally an ISAF port of call, but was taken by Erusian forces sometime in late 2003 or early 2004. The harbor quickly became the frontline logistics and repair center for the Federal Erusian Navy's east coast operations. In late 2004, as the ISAF began to mount a counterattack, the Erusian High Command in Farbanti deployed the Aegir Fleet to Comberth in preparation for a large-scale invasion of North Point, the new ISAF GHQ. Sometime before September 7, the Aegir Fleet docked at Comberth to undergo refueling and resupply operations before setting sail for North Point.[2]

ISAF command recognized that a direct assault on the Aegir Fleet would spell certain disaster for its naval forces. Instead, ISAF squadrons attempted to halt the Erusians' resupply efforts by intercepting a convoy of transport aircraft inbound to Comberth. The operation proved successful, and the ISAF was able to temporarily delay the fleet's launch.[2]

Following the success of Operation Hunting Hawk, the ISAF targeted a major Erusian petrochemical complex northeast of Comberth that was supplying the fleet's refueling efforts. ISAF fighters inflicted considerable damage to the drilling platforms and refinery facilities, effectively robbing the Erusians of the five million barrels of crude oil stockpiled there.[3]

The actions of Operations Hunting Hawk and Early Bird successfully immobilized the Aegir Fleet and gave ISAF the advantage it needed to strike.

On November 23, 2004, at 1200hrs, ISAF fighter squadrons entered Comberth Harbor airspace and caught the unprepared Aegir Fleet in a large-scale surprise attack. The squadron split into four groups to maximize damage within the main target areas of the harbor: the shipyard and dry-dock facilities housing docked warships, the submarine docks to the east, the fuel and ammo dump, and the fleet's capital ships attempting to escape to open waters.[1]

The duration of the operation was extended. Harbor servicing facilities were crippled and the flow of military supplies was critically weakened. Every Erusian naval vessel in the harbor area was either sunk or irreparably damaged; fuel reserves were decimated as well. The ISAF raid completely annihilated the Aegir Fleet, including its support vessels, landing forces, and even the fleet's flagship, the battleship Tanager. Any plans for an Erusian invasion of North Point were "delayed indefinitely". The collateral damage and extremely high casualty rates suffered during the attack made Erusian officers wary of the Ribbon's aerial dominance.[1]
