Vietnam: Coastal Divsion 12

1967-1970

Collection Number: AR/482 (Formerly COLL/462)

Historical Note:

Coastal Division TWELVE was originally PCF Division 102 (PCF stands for Patrol Craft Fast, aka Swift Boats). Its primary mission was to interdict ships from North Vietnam and prevent supply offloading in South Vietnam, with the secondary mission of providing gunfire support for ground troops.

PCF Division 102 deployed from Coronado, California, in December 1965 to Subic Bay, Philippines. Then it established a base of operations in DaNang, Vietnam, on 13 January 1966. Soon after, PCF Division 102 participated in Operation Market Time and was part of Task Group 115.1. It patrolled areas, between the DMZ and the southern I Corps boundary, using Swift Boats. On 1 January 1967, PCF Division 102 changed its name to Coastal Division Twelve.

In 1967, Coastal Division Twelve participated in the operations listed below:

• Operation Market Time

• Operation DeSoto

• Operation Deckhouse VI

• Operation Beacon Hill One

• Operation Seahawk

• Operation Boone

• Operation Canyon

• Operation Beau Diddley

• Operation Beacon Star

• Operation Beau Charger

• Operation Bear Claw

• Operation Bear Bite

• Operation Beacon Torch

• Operation Dragon Fire

• Operation Ballistic Charge

• Operation Beaver Cage

• Operation Badger Tooth

• Operation Fortress Ridge

In addition, Coastal Division Twelve formed Coastal Division Sixteen, which lasted from 20 June 1967 to 1 November 1967. The Division continued its participation in Operation Market Time through 1968.

The Division's last complete year of operations was 1969. During this year, it trained the Vietnamese for the eventual turnover of Coastal Division Twelve to the South Vietnamese Navy. On 1 March 1970, Coastal Division Twelve was to be primarily manned and controlled by the South Vietnamese. In the interim, it participated in several operations:

• Operation Market Time

• Operation Bold Mariner

• Operation Sea Tiger

• Operation Daring Rebel
