History
Coastal Defence Command was formed in 1992 under the control of the Royal Fleet Headquarters, with one coastal defence regiment and one air defence regiment. Personnel were initially drawn from the Royal Thai Marine Corps, but are now being recruited directly. The First Coastal Defence Regiment is based near the Marine Corps facility at Sattahip. The First Air Defence Regiment was near the Naval Air Wing at Utapao. Coastal Defence Command was greatly expanded in 1992, following the government's decision in 1988 to charge the RTN with the responsibility of defending the entire eastern seaboard and Southern Seaboard Development Project. The Second Air Defence Regiment, based at Songkhla, was then formed the following year. Some analysts believe that this element will eventually grow to a strength of up to 15,000 personnel.
