Annex 4 supports China Lake and Point Mugu Ranges in California.
China Lake, in California's Mojave Desert, is home to NAVAIR's Naval Air Warfare Center Weapons Division (NAWCWD). Few areas in the world offer such wide variety of geographical features in close proximity...mountains, deserts, canyons, caves and forests. The unencroached 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.
NAVAIR Point Mugu is located at Naval Base Ventura County, just west of Los Angeles. It was established in 1946 as the Navy's first instrumented missile test sea range. It offers enormous geographic diversity: vast ocean, deep water ports, protected islands within restricted air space. The 36,000 square-mile sea range, which includes San Nicolas Island, supports both developmental and operational test and evaluation of missiles, free-fall weapons and electronic warfare systems.
