Lake Chabot Machine Gun Range
With the start of World War II, the Navy established a gunnery range on a watershed area adjacent to the Lake Chabot Reservoir.
The Navy built a circuit training range on which gunners would fire turret mounted machine guns that were built onto the beds of light trucks, rail cars, and fixed firing platforms. Gunners would engage targets that were on an automated circuit on small rail cars. This would simulate firing in air-to-air combat.
In addition to the automated circuit range, there was a shotgun range that was used for the primary training of aerial gunners. This was basically a skeet range in which trainees would learn the fundamental techniques of aerial gunnery, such as proper sighting of fast moving targets.
The base ceased operations in 1947.
