Epsilon Systems supports the Naval Air Warfare Center Weapons Division (NAWCWD) at China Lake. Support includes environmental management, natural and cultural resources preservation and geographical information systems such as the Mission Capability Analysis Tool (MCAT). The un-encroached air and land ranges at China Lake provide unmatched geographic conditions in which to develop and test weapon systems and explore tactics for desert and mountain environments. China Lake provides efficient deployment of new weapon systems through its collocated laboratories, ranges, and weapons test squadrons. The site supports fleet training and tactics development, including major exercises on the Land Range, Superior Valley Tactical Training Range and Electronic Combat Range. The one million acres of Navy-owned lands within the remote Mojave Desert at China Lake has elevations spanning from 1,400 to 8,800 feet above sea level. The NAWCWD also manages the 36,000 square mile Sea Range at Point Mugu, California, including San Nicolas, and portions of Santa Cruz and San Miguel Islands.
