LIGHTWEIGHT VIDEO SIGHT II
Crew Served Weapons Fire Control System
DETECT, RECOGNIZE, IDENTIFY AND ENGAGE TARGETS IN BOTH DAY AND NIGHT CONDITIONS
The Crew Served Weapons Lightweight Video Sight II (LVS II) is an integrated module that allows the operator to engage targets using the most sophisticated fire control available for crew served weapons.
The Lightweight Video Sight II (LVS II)
The Lightweight Video Sight II (LVS II) is designed and integrated with the MK47 and MK19 40mm Grenade Machine Guns as well as the M2/M2A1 .50 caliber machine gun. The system is operated by controls mounted to the back plate of the host weapon, which allow the operator to navigate a graphical user interface presented on the video display. A laser range finder enables the operator too quickly and accurately determine distance to target. This information, combined with data from integrated sensors (air temperature, atmospheric pressure, sight pitch and sight cant) and various user inputs (such as ammunition type, range wind, and cross wind) are fed into a ballistic solution algorithm (BSA) and used to calculate the ballistic solution. The solution is presented to the operator as a corrected aim-point on the color LCD flat panel.
The next generation of fire control system available for
crew served weapons.
Another key feature of the LVS II is the method of super elevation, required when firing 40mm ammunition. This allows the operator to maintain the target image within the operator’s field of view of the LCD display while super-elevating the weapon to obtain a correct ballistic solution.
The LVS II is also fully compatible with the MK285 40mm Air Bursting Ammunition, a round which is fully integrated with the MK47. The LVS II is designed to replace the existing lightweight video sight currently used with the MK47 MOD O Advanced Lightweight Grenade Launcher, while retaining the menu options to minimize training costs.

Key Sub-System Descriptions
Video Display
The LVS II uses a color 1024 x 768 flat panel LCD to present the operator with target area imagery overlaid with a graphical user interface (GUI).
Night Optics
The LVS II uses a 17μm, 640 x 480, 30 Hz thermal imager that provides a fixed 3X standard level of magnification with a 5 degree horizontal and 4 degree vertical field of view.
Laser Range Finder (LRF)
The LVS II uses an integrated 1,550 nanometer LRF that is eye safe per ANSI Z136.1 Class 1M and undetectable with night vision devices based on image intensifier tubes.
Ballistics Processor Module (BPM)
A high-performance computer processor executes a ballistic solution algorithm (BSA).
Day Optics
A full color, high resolution day video camera provides a fixed 3X standard level of magnification with a 5 degree horizontal and 4 degree vertical field of view.
Power
A single BB-2590 or BA-5590 internal back-up battery supports a minimum of eight hours continuous operation on a fully charged battery.
