The mount provided an elevation from minus 5 degree to plus 45 degrees with an elevation rate of ten degrees per second. The mount could be trained to plus or minus 90 degrees from the centerline of the vessel with a train rate of six degrees per second. The guns could be loaded at any degree of train but only between minus 5 and plus ten degrees in elevation. The loading cycle started with the rammer cocked by the recoil of the guns.
