The BBAF-1001 Avalon (アヴァロン Avaron) is a Britannian airship owned by Lelouch Vi Britannia, and the first of its kind introduced. It is named after Avalon, a mythical island from Arthurian legend. It uses a Float System for flight, allowing it to hover in place for an unlimited time period.
Designated as a Avalon-class Air Fleet Battleship and measuring at 200 meters, the Avalon is a large ship of style and has many quarters, conference rooms and recreational rooms on board. The bridge of the ship has a command platform over other controls platforms, with stairs between the platforms. The bridge's windows can, like in many Britannian ships, become tactical screens for battle strategy and communication purposes.
For defenses, it features Blaze Luminous shielding initially only on its underside, but that was later expanded to encompass the whole ship. Blaze Luminous is a system that projects energy in the form of shields around a nearby target and is impossible to break unless turned off. For offense, it has automatic machine gun turrets spread across the hull and missile launchers along the topside. Most notable is the electromagnetic cannons attached to it as a main deterrent as well as offensive weapon.
