disappearing carriage mount

The disappearing carriage was a military technology primarily used for coast guns. This mounting system allowed a gun to be raised above a protective parapet for firing and then automatically lowered behind it after discharge. This design, featuring arms hinged to a rotating base, used recoil to sink the gun into a pit for reloading, making it a safer target for enemy fire. While widely adopted, its complexity led to its decline in the 1890s, though some remained in use into the mid-20th century. The barbette mounting eventually became the preferred pattern for coastal defense.12
