Excalibur (エクスキャリバー Ekusukyaribā) was a chemical laser weapon constructed by Belka between the late 1980s and early 1990s. Excalibur was originally conceived as a long-range, anti-ICBM defense system. During the Belkan War, it was used as an anti-aircraft weapon to moderate success until its destruction in May 1995 by the Allied Forces' mercenary ace, Galm 1.
