Sa Huỳnh Base (also known as Sa Huỳnh Naval Support Activity or simply Sa Huỳnh) is a former U.S. Navy, U.S. Army and Army of the Republic of Vietnam (ARVN) base in southern Quảng Ngãi Province in south-central Vietnam.
The base was located east of Highway 1 at the mouth of an inlet, some 18 km southeast of Đức Phổ Base Camp and 100 km south of Danang.[1] From 16–26 February 1967 the Marines Special Landing Force comprising 1st Battalion 4th Marines and HMM-363 conducted Operation Deckhouse VI an amphibious assault on Sa Huỳnh to clear Vietcong infiltration routes and secure an area to serve as a logistics support base for allied units operating in the area.[2]
The U.S. Navy built the Sa Huỳnh Naval Support Activity in mid-1967 to support the arrival of the Army's Task Force Oregon in the area.[2] [3]
On 15 February 1970 Sa Huỳnh Naval Support Activity was disbanded and its facilities were transferred to the U.S. Army Support Command.[4]
On 27 January 1973 the day before the ceasefire was to come into effect the People's Army of Vietnam (PAVN) 141st Regiment captured Sa Huỳnh. The ARVN 2nd Division launched a series of counterattacks, forcing the PAVN out of Sa Huỳnh by 16 February 1973.[5]
