A disappearing gun (often called a disappearing carriage) was a type of heavy (mainly coastal) artillery used in the past for which the gun carriage enabled the gun to rotate backwards and down into a pit protected by a wall (the parapet) or a bunker after it was fired. This retraction lowered the gun from view by the enemy while it was being reloaded. Some disappearing guns also used compressed air, while a few were built to be raised by steam.

  • A disappearing gun (often called a disappearing carriage) was a type of heavy (mainly coastal) artillery used in the past for which the gun carriage enabled the gun to rotate backwards and down into a pit protected by a wall (the parapet) or a bunker after it was fired. This retraction lowered the gun from view by the enemy while it was being reloaded. It also made reloading easier, since it lowered the breech to a level just above the loading platform, and shells could be rolled right up to the open breech for loading and ramming. Although it had these advantages, the disappearing carriage was also a complicated mechanism. In the U.S., disappearing carriages were mostly withdrawn from active service by the early 1920s. The disappearing gun was usually moved down behind the parapet or into its protective housing by the force of its own recoil, which (on many models) lifted a counterweight. Before firing, the crew tripped a catch on the counterweight, causing it to fall into a well at the center of the gun position and move the gun back up "into battery" (firing position). Some disappearing guns also used compressed air, while a few were built to be raised by steam.
