In October 1978, Coastal River Squadron ONE became Special Boat Squadron ONE, spawning three commissioned units -Special Boat Unit ELEVEN (NRF), located at Mare Island, Vallejo, California; Special Boat Unit TWELVE (Active Duty); and Special Boat Unit THIRTEEN (NRF), both located at Coronado, California. In August 1993, the newest addition to the Special Warfare Craft inventory came in the form of the Patrol Coastal (PC) ships. The PCs are designed for fast maneuverable littoral warfare, capable of long range and extended operations. The PCs proved their worth on their maiden cruise when they deployed to Haiti for Operation SUPPORT DEMOCRACY in 1994; they performed invaluable service in every mission area, from coastal patrol and interdiction to SEAL support.
In July 1994, Special Boat Squadron ONE reached a new milestone, elevation to Echelon III status and assumption of major command duties and responsibilities.
