Unique among most naval weapons facilities, Detachment Fallbrook is located 9 miles inland. Ammunition is transferred to and from ships by a process known as Vertical Replenishment. In this operation, ammunition is taken by truck from a magazine on base to a helicopter pad located inside Camp Pendleton. From there MH-60S Seahawk helicopters pick up the load and transfer it to the receiving ship waiting several miles off the coast. In this manner, large vessels such as amphibious assault ships can be loaded without leaving their primary Southern California operating and training areas. Detachment Fallbrook is home to the only West Coast Air-Launched Missile Production and Storage Facility.
