A Mk 5 Mod 0 US Navy Stadimeter made in 1942 by Schick Inc. of Stamford CT. The hand held stadimeter was developed by Bradley Allen Fiske (1854–1942), an officer in the United States Navy. It was designed for gunnery purposes, but its first sea tests, conducted in 1895, showed that it was equally useful for fleet sailing and for navigation.
One solution, implemented in 1943, was to replace each of the PT Boat's two to four Mark 8 torpedoes, and their Mark 18 torpedo tubes, with the significantly lighter Mark 13, carried in lightweight Mark 1 launching racks, at a total saving of more than 1,400 pounds (635 kg) each. The shorter Mark 13 also took up less deck space.
The Mark 34 Gun Weapon System (GWS) is a component of the Aegis Combat System that is responsible for controlling and providing fire control to the 5" Mark 45 gun. It is used on the U.S. Navy Arleigh Burke -class destroyer and several later Ticonderoga -class cruisers. The Mk 34 GWS receives target data from the ship's sensors and off-ship ...
Pulsewidth. 0.3 μs. Range. 23 km (12.42 nmi) Precision. 14 m (15 yd) Power. 25-50 kW. Mark 63 Gun Fire Control System (Mk.63 GFCS) is a gun fire-control system made up of AN/SPG-34 radar tracker and the Mark 29 gun sight. [1][2] They were usually equipped for the control of twin QF 4-inch naval gun Mk XVI and Mk.33 twin 3"/50 cal guns.
[4] [3] The latest Mk 38 Mod 3 mounting has further upgraded interfaces and control consoles. The EO/IR sensor and laser rangefinder, integrated with the system's fire-control system, provide a 330-degree view, "even in extremely low light conditions". The surveillance system can move independently of the turret itself, intended to minimize ...
The AGM-45A used the Rocketdyne Mk 39 Mod 0 (or apparently in some cases the Aerojet Mk 53 Mod 1) motor, while the AGM-45B used Aerojet Mk 78 Mod 0 which greatly increased the range of the missile. As for warheads, the Mk 5 Mod 0, Mk 86 Mod 0, and WAU-8/B could all be fitted to the AGM-45A and were all blast-fragmentation in nature.
The limited ammunition capacity was an important disadvantage. The Type 99 Mark 1 Fixed Model 3 could be equipped with a 100-round drum, but the size of the drum was itself a problem in fighter installations, although the Model 3 guns were installed on the initial production versions of the A6M3. A more practical solution was provided by the ...
The MK 13 rifle is made using the Accuracy International Chassis System (AICS) version 2.0 mated to a long action Remington 700 receiver. The AICS 2.0 folding stock reduces the rifle's overall length by 210 mm (8.3 in) when folded and adds 0.2 kg (0.44 lb) to the rifle's total weight. The rifle has a cheekpiece design that adjusts sideways and ...
