Assault Craft Unit FIVE

ACU-5 was commissioned on October 1, 1983 in Panama City, Florida, with the first craft delivered in December 1984. The first operational deployment of LCAC was in 1987, during which the first LCAC landing outside the United States was conducted in support of amphibious operations in Okinawa. A detachment of maintenance personnel was deployed to Japan on a permanent basis to support LCAC operations in the Western Pacific.

The largest deployment of LCAC occurred in 1991. Eleven craft were stationed in the Persian Gulf in support of OPERATION DESERT STORM. In October 1992, three LCAC deployed to Sasebo, Japan as DETACHMENT WESTPAC ALFA, establishing a permanent forward presence which remains to this day. During a separate deployment that same month, three LCAC conducted landings in Somalia in support of OPERATION RESTORE HOPE. The command regularly deploys LCAC with the Amphibious Readiness Groups (ARGs) of the Pacific Fleet, conducting operations and exercises throughout the Persian Gulf, and the Indian and Pacific Oceans.

Closer to home, recent operations have included participation in EXERCISE KERNEL BLITZ 1999, the largest amphibious exercise on the west coast, and support in fighting wildfires on Santa Catalina Island. Under a unique agreement between the U. S. Navy and the Los Angeles County Fire Department, LCAC are used to transport fire fighting vehicles, personnel, and equipment from the mainland to Santa Catalina. The agreement was put to use in July 1999 when ACU-5 was called upon to help combat a 100-acre brush fire on the island.

The ACU-5 compound encompasses 48 acres with 225,000 square feet of office and work space to support 40 craft and over 700 personnel. Construction of the current facilities commenced in 1985 and the final phase was completed in the summer of 1996.
