Design overview
Design overview
The weapon is mounted on a stabilized pedestal mounting which allows it to remain on target as the platform beneath it moves. The mounting does not penetrate the platform (except cables), making it relatively simple to fit the weapon to ships. Electroptical suit of SMASH 200/25 is independent and separately stabilized. This enables surveillance and target tracking without aiming the gun to the target. Using its sight the SMASH 200/25 system can provide surveillance and target-tracking entirely without outside assistance, allowing it to function fully independently. This sight includes a thermal camera, a TV camera, and a laser range finder. The system performs automatic ballistic calculation for the weapon. It allows for day and night operation under various weather and terrain conditions. It also can be integrated with combat management system of a ship. Its integrated training simulator provides crew training. There is also a manual operation mode as a back-up. The user interface provides an advanced graphical display with Picture-In-Picture functionality. The system is designed for integration with external platform sensors such as radar and wind sensors. The sub-units that comprise the system include a stabilized turret, an independent stabilized optical director, a mission computer, a gun control unit, a servo controller, a power unit, an electronic control and interface unit, and a system operating panel. Additional components consist of a 19-inch panel PC display, a commander control unit, a safety switch, and an optional slip ring. 250 (2 x 125) rounds are carried on the mounting with dual feed system. The mount can traverse 360° when EO sights elevate between -30 (±2)° and +80 (±2)° and gun elevate between -15 (±2)° to +55 (±2)°. The structure is modular to allow for future upgrades and options. Built-in test capabilities and embedded video recording are included. Power is supplied by a 110/220 V AC 50/60 Hz source and a back-up battery unit is included.
