At arms length, he had switches for controlling communication, emergency lighting, and battle lanterns. His duties during Automatic Control were to receive action orders from the battery commander (e.g., "Mount 51, plot. Surface action starboard. Target destroyer. Bearing 060. Range nine thousand, five hundred yards. Slow salvo."), give the appropriate orders to his Gun Room and Upper Handling Room crews (e.g., "Match pointers. Switch to automatic. Handling room fill the hoists with able able common and full service charge. Standby for slow salvo."), verify that his orders were being followed, and report his gun's status back to the battery commander (e.g., "Plot, mount 51 in auto. Bore clear."). In Local Control, he aimed and fired his mount's gun(s)âsometimes without external help. With his gunnery binoculars, he estimated the range to the target, and its bearing rate. He then mentally converted these into range and deflection orders to his Sight Setter. After firing, he observed the fall of his shot, and made sight corrections to his Sight Setter if necessary.
1813:) (Also called Separated Ammunition.) Each round consists of a projectile and a powder case. The two parts of the round are kept separate until they get to the gun. At the gun, they are first combined on the rammer tray, and then power rammed into the chamber together with one ram cycle. The powder case completely fills the volume of the chamber, and its length seats the projectile's rotating band into the bore's rifling. This is different from a naval bag gun. In a bag gun: (1) The projectile, by itself, is power rammed into the chamber until its rotating band is seated in the bore's rifling. (2) The rammer is retracted. (3) The powder bags are then rammed in. This is also different from some artillery field guns: (1) The projectile is hand rammed into the chamber with a ramrod until its rotating band is seated in the bore's rifling. (2) The ramrod is retracted. (3) Next powder is placed in the chamber either as a bag or primed canister with the required charge. Note that the single ram operation used in semi-fixed guns decreases the loading time, and therefore increases the firing rate on medium and large caliber guns. For example, each of the nine 8"(203 mm)/55-caliber Rapid-Fire guns installed on the

1695:. When the Mount Captain commands, "Match pointers. Switch to Automatic.", he looks down at the dials on his Indicator-Regulator. The dials also tell him the difference between the gun's present train angle and the ordered train angle. He changes the bearing of the gun, by moving his hand wheels, until the dial difference is zero. His dials are now "matched", and he switches the train drive into Auto. This disengages his hand wheels, and gives train angle control to the Fire Control System. Then, he reports back to the Mount Captain, "Train in auto." He may now look through his sight, and if the Sight Setter has matched the sight-setter dial pointers, he will see the target in the cross-hairs. When the Mount Captain commands, "Switch to Local", he switches the train drive to local. In local control, he controls the gun's train angle with his hand wheels to keep his sight's vertical cross hair on the target.
1663:. He changed the elevation of the gun, by moving his hand wheels, until the dial difference was zero. His dials were now "matched", and he switched the elevation drive into Auto. This disengaged his hand wheels, and gave elevation control to the Fire Control System. Then he moved the Electrical Fire Select Switch to "AUTO", and reported back to the Mount Captain, "Elevation in auto." He would now look through his sight, and if the Sight Setter had matched the sight-setter dial pointers, he would see the target in the cross-hairs. When the Mount Captain commanded "Switch to Local", he switched the elevation drive and the Electrical Fire Select Switch to local. In local control, he controlled the gun's elevation with his hand wheels to keep his sight's horizontal cross hair on the target. At the command of the Mount Captain, he fired the gun by squeezing the firing key on his right hand wheel.

a misfire. Due to its importance, it is kept in a special container in the mount whenever the ship is in a combat zone. A misfire is especially dangerous in semi-fixed guns. When the breech is opened after the misfire, the faulty powder case can be extracted, but the projectile will remain jammed in the rifling. Also, all or part of the extracted case's cork plug may still be wedged in the chamber behind the projectile. This "fouls" the chamber because it decreases the chamber's volume. And, since Full and
Reduced charge cases take up the full volume of an unfouled chamber (see loaded Semi-Fixed round drawing above), any residue left from the previously extracted case will prevent them from fully loading into the chamber. Therefore, the clearing charge is made short so that it will fit into a fouled chamber.

is automatically set as it goes up the hoist, and the hoist maintains the ordered fuze setting from the fire control system as long as the projectile stays in the hoist. The powder case is sent up through a powder scuttle in the gun room's deck just next to the powder man's feet. It arrives with its base up, and the primer covered with a protector called the "Butterfly". The men in the upper handling room hand carry the projectiles and powder cases from the ready service racks to the lower ends of the hoists while avoiding the equipment hanging down from the rotating mount. In a twin mount executing "Rapid continuous fire" (the firing keys are held closed, and the gun fires as soon as the breech closes), the crew move 30 to 44 projectiles and powder cases per minute.

He could verify that the gun returned to battery before the next round was loaded. If something went wrong, he was free to move around his gun to fix the problem. He knew everyone's job, and could step in if necessary. At the mount captain's command, he manually opened the breech block before the first round was loaded, and reported if the bore is clear. His duties were the same in automatic or local control.

Now it is also used in shore bombardment and surface actions against fast boats.

This would result in large walls of shell fragments being put up to take out one or several planes or in anticipation of an unseen plane, this being justifiable as one plane was capable of significant destruction.

506:). The air pressure in the chamber attempts to push the piston out of the chamber, but the piston can't move because of the slide. Therefore, since the piston can't go backwards, the air pressure in the chamber forces the housing forward. When the gun is in battery, the pressure in this chamber is about 1,500 psi (10 MPa). During recoil, the pressure rises to about 2,250 psi (15.5 MPa).

In early open mounts, this was done by moving the platforms to which the sights were bolted. Sights in enclosed mounts have movable prisms in their optical paths. The sight setter has three dials, and two hand cranks. (

1860:. This band has a diameter larger than the bore, and when the projectile and powder case are rammed into the chamber, the band is jammed into the grooves of the bore's rifling. It forms a gas seal between the projectile and the bore. Also, as the projectile travels down the barrel, the band grips the rifling to impart spin to the projectile.
1038:(1937). Some of these mounts placed on ship's forecastles were partially enclosed to protect the crew against bow spray, but they were still considered an open mount. Since these mounts did not have Upper Handling Rooms, they could be installed on ships without extensive reconstruction. For that reason, they were frequently used on

Millions of rounds of ammunition were produced for these guns, with over 720,000 rounds still remaining in Navy storage depots in the mid-1980s because of the large number of Reserve Fleet ships with 5"/38 cal guns on board.

This would dial in the ordered fuze time into that projectile. The powder case is placed in a rack bolted to the mount's deck just behind the powder-man's feet.
