The barbette-carriage belongs to that class which has been denominated immovable. That is to say, it is used simply to fire the piece from, and not to transport it except for very short distances.

The barbette-carriage is used only in a fixed position in garrison, and is a carriage on which a gun is mounted to fire over a parapet instead of through it, as siege or sea-coast guns usually fire. A barbette-gun is any gun mounted on a barbette-carriage. There are but two forms of the barbette-carriage in the United States service:

• One for the iron guns and sea-coast howitzers (12,18,24, 32,42-pdr. and 8 and 10-in.)
• One for the columbiads.
