Guns used as weapons or protection

There are two categories of destructive devices DDs:

Guns used as weapons or protection

The mountings for the never-built Montana BB class were to have been to a similar design but with thicker armor protection. Each gun had a 60 hp motor for elevation, a 60 hp motor for ramming, a 75 hp motor for the shell hoist and a hp motor for the powder hoist.

Each shell ring was powered by a 40 hp motor. Training arcs were restricted during the s activations in order to avoid overpressure problems to the new electronic and missile installations.

The absolute, metal-to-metal recoil distance was 48 inches cm. During runout, the gun is automatically lowered to the loading position, thus speeding up the firing cycle time.

The Mark 52 weighs 10, lbs. Near focus for the Mark 52 is 5, yards 4, m and the maximum range is 45, yards 41, m. Mark 53 was a coincidence type with a special astigmatic lens which allowed it to range in on a single point source, such as a searchlight.

In the s, the Mark 53 rangefinder was removed from all four Iowa class battleships as weight compensation for growth in other areas. This rangefinder was selected as the increasing sophistication of fire control radar made its special capability redundant. The lower height of Turret I above the water also meant that this mounting had a shorter distance to the horizon capability.

The openings in Turret I were then armor-plated over, as can be seen in the photographs below.

Assault Weapons

Each turret requires about 94 men to operate, including the crew in the magazine and shell handling spaces. These mountings used delay coils, which delayed the firing of the guns by about 0. This delay, plus a wider spacing between the gun barrels than on the older ships, improved the dispersion patterns.

The firing order was left, right, center. During the s activations, agastats time delay relays were fitted to the right and left gun and these created a turret-whipping problem.

This was corrected by increasing the delay in the right gun to 1 second. Wisconsin differed from her sisters in having a 1 second delay for the left gun and 2 seconds for the right gun.

No intent to harm

The gun axes are in cm apart according to BuOrd OP When inspected during the initial reactivation process in the s, all twelve turrets on the four battleships of the Iowa class were found to be in excellent shape thanks to the care taken during their deactivations.

These guns were unable to hold elevation and would oscillate around at the desired setting. Investigation of the historical records showed that the problem had existed at the time of her deactivation and that major repair efforts had been underway at that time.

Repairs during the s reactivation were hampered by the thirty-year hiatus since she was placed in reserve, as this meant that very few personnel were familiar with the complexities of the equipment.

This necessarily meant that a long learning process was required to acquaint maintenance personnel with the equipment involved.

The preservative, because of the long term deactivation period, had become hardened, making it difficult to remove. As the systems were reactivated and operated, this preservative would continually work loose.

This material would then clog orifices, etc. Eventually, the source of the problem was pinpointed on both guns. For one of these guns, it meant the replacement of a major assembly - the A-end pump. The other gun was corrected by replacing a major sub-assembly and the fine adjustment of the regulator assembly" - from "Reactivation of inch Three Gun Turrets in the Battleship.

Because of deterioration from age and use, all of the original valves were not able to hold pressure and so were replaced by a commercially available valve that was a direct replacement for the original one.

Repair kits containing the new valves were added to the Naval supply system to ensure logistical support. To solve the problem with the preservative fouling the hydraulic systems, a large capacity 0.

These units worked continuously to filter the hydraulic fluid. This system was outside of the normal hydraulic system and operated even when the mountings were not in use, thus ensuring cleanliness of the hydraulic fluid.

The Uzi is a family of Israeli open-bolt, blowback-operated submachine guns. Smaller variants are considered to be machine pistols. The Uzi was one of the first weapons to use a telescoping bolt design which allows the magazine to be housed in the pistol grip for a shorter weapon.
