The RAN’s primary contribution consisted of destroyers, Fleet Air Arm personnel attached to a United States (US) Army assault helicopter company and the Royal Australian Air Force’s (RAAF’s) No. 9 Squadron, a Clearance Diving Team, and a logistic support force consisting of transport and escort ships.
RAN warships provided naval gunfire support from March 1967 to September 1971. They also participated in Operation SEA DRAGON, the bombardment of North Vietnamese military targets and the interdiction of supply routes and logistic craft along the coast of North Vietnam from the Demilitarized Zone to the Red River Delta, from April 1967 until it was suspended in November 1968.
The first RAN destroyers to deploy to Vietnam were the Charles F Adams Class guided missile destroyers (DDG)
Hobart,
Perth and
Brisbane. The Daring Class destroyer HMAS
Vendetta was also deployed for service on the gunline.
Hobart and
Perth deployed three times to Vietnam,
Brisbane twice and
Vendetta once. The destroyers carried out NGS missions in all of South Vietnam’s four military regions and
Hobart and
Perth were actively involved in SEA DRAGON.
Hobartand
Perth came under fire on a number of occasions.
Perth was hit once during her first deployment and
Hobart suffered two killed and seven wounded when she was mistakenly hit by missiles fired from a United States Air Force jet aircraft.
In their five years service in Vietnam, the four gunline destroyers steamed over 397,000 miles and fired 102,546 rounds.
Clearance Diving Team Three (CDT3). The first contingent of six personnel arrived in Vietnam on 6 February 1967 and were initially attached to a United States Navy Explosive Ordnance Disposal Team based in Saigon. They then moved to Vung Tau and assumed responsibility for the defence of shipping against enemy attack, known as Operation STABLE DOOR. In August 1970 CDT3 was relieved at Vung Tau by South Vietnamese Navy personnel and airlifted to Da Nang. In three and a half years on Operation STABLE DOOR, CDT3 searched 7441 ships.
HMAS
Sydney (III) was converted for troopship duties in the early 1960s and began her first voyage to Vietnam in May 1965, transporting the First Battalion, Royal Australian Regiment, from Sydney to Vung Tau in southern Vietnam.
Between 1965 and 1972, HMAS
Sydney (III) undertook 25 voyages to Vietnam and transported 16,094 troops, 5753 deadweight tons of cargo and 2375 vehicles.
On every voyage HMAS
Sydney (III) was ably supported by at least one escort that provided a measure of protection against potential hostile forces. She had up to four escorts in 1965 and 1966, including at times the flagship HMAS
Melbourne. Other escorts included HMA Ships
Anzac,
Derwent,
Duchess,
Parramatta,
Stuart,
Swan,
Torrens,
Vampire,
Vendetta and
Yarra.
Between 1967 and 1971 the Royal Australian Navy Helicopter Flight Vietnam (RANHFV), was fully integrated with the US Army 135th Assault Helicopter Company (AHC) flying Iroquois helicopters in both the utility and gun ship configurations. As a result of this unique relationship between the RAN and the US Army, the unit was officially designated ‘EMU’, for Experimental Military Unit.
