Swivel Cannon is a naval technology in Age of Empires IV: Anniversary Edition available at the Dock in the Imperial Age. It grants all springald ships an additional cannon attack. The cannon attack deals 15 siege damage and can be fired in all directions, regardless of facing.
The additional projectile also benefits from Springald Crews, but not Mounted Guns.
