Day / Night Crew Served Weapon Sight System Solutions

The Marines require a replacement for technologically obsolete thermal weapon sights (MWTS, HWTS) for medium 7.62mm (M240B) and heavy 12.7mm and 40mm (M2A1, MK 19) machine guns. These single function devices fail to provide target range determination and lack the clarity and range of systems used during the daylight. Also, newer emerging medium machine guns (MMG) have the potential to provide heavy machine gun range in a more compact weapon system in the near future. Wilcox plans to investigate modular and fully integrated solutions with careful consideration to existing reliable optical day sights in service. Wilcox plans to assess the integration of day cameras versus modular approaches for use of existing direct view optics in combination with modern, small pixel (10 microns) thermal weapon sights. Integration of day cameras has been met with significant user challenges in the past due to power demands, cost and performance.  The MK 19 poses some unique challenges based on its direct and indirect fire capability. The super elevation mode is an important parameter for consideration of various system trades.  The opportunity exists to take a fresh look at the problem. System trade studies will guide the effort under the Phase I effort considering the latest technological developments. The Phase I base objective is to define and develop a system architecture for a day and night capable target acquisition and engagement sight system for crew-served small arms weapon systems. The system combines the functionality of multiple legacy sight systems while providing additional performance and capabilities. Phase I will establish the feasibility of the system architecture by conducting technology trade studies and analysis of all architecture options. Technology trades that will be reviewed with the government include Integrated vs. Modular Approach, Range Performance, Optical Performance, Physical Performance, and Power Capability. The outcome of the Integrated vs. Modular Approach trade study will strongly influence the course of action for the rest of the trades. Wilcox and the government will work together to select the appropriate technology based on the objective results of the trade studies as well as the preferences of the user community.
