The electrolaser cannon is a unique weapon featured on the Spiridus in Ace Combat: Joint Assault. The cannon guides an electric yellow laser through a path of ionized air, then uses a red laser for targeting.
The Valahia used the electrolaser cannon as the weapon of choice during the Spiridus's attack on London. Antares One destroyed all of the lasers and subsequently destroyed the Spiridus itself.
The Golden Axe Plan Private Army's upgraded Spiridus also featured the electrolaser cannon. Antares One also destroyed this cannon as well as the upgraded Spiridus.
