The naval mount kept the large-caliber automatic-gun concept but packaged it for smaller warships. NavWeaps describes two ready-use magazines beside the breech, dual feed trays below the magazines, a rod hoist from the below-deck magazine, gyro-stabilization, and remote automatic operation with local-control backup.
Ready feed52 rounds in the feed system, with ready-use magazines on both sides of the breech and six-round feed trays beneath them.
Reloading limitRounds already in the feed system could be fired at any elevation, but the feed system was reloaded with the gun at +80 degrees.
Local backupNavWeaps lists an operator and two ammunition loaders for remote operation, with additional crew for local control and below-deck magazines.
