This blog is part of a series honoring the long blue line of Coast Guard men and women who served before us. Stay tuned as we highlight the customs, traditions, history and heritage of the Coast Guard.

“I want to make sure that the Coast Guard people in Vietnam know that I am hearing about them often and that I am pleased with what I hear.”
–General Wallace Greene, Jr., commandant, U.S. Marine Corps, 1967

As indicated in the quote above, the Coast Guard played a vital role in the Vietnam War, but the service’s combat operations in South East Asia remain unknown to most Americans.

On April 29, 1965, President Lyndon Johnson signed a “Memorandum for the President” that required “U.S. Coast Guard operating forces assist U.S. Naval Forces in preventing sea infiltration by the communists into South Vietnam” stating “…that the U.S. Coast Guard has operating forces which are well-suited to the mission…” The same day Johnson signed his memorandum, the service announced formation of Coast Guard Squadron One (RONONE). The squadron consisted of 26 “Point”-class 82-foot patrol boats. In five years, RONONE patrol boats cruised over four million miles and inspected over 280,000 vessels. The 82-footers, which were designed for search-and-rescue and law enforcement, were operational approximately 80 percent of their time in theater.

In early 1967, the Navy requested that the Coast Guard provide five high-endurance cutters for duty with the Navy’s Coastal Surveillance Forces. On April 24, Coast Guard Squadron Three (RONTHREE) was formed at Pearl Harbor, Hawaii, and, in May, the high-endurance cutter Barataria fired the first RONTHREE naval gunfire support mission of the war. In February 1968, cutters Winona and Androscoggin engaged enemy trawlers and destroyed them with the aid of Coast Guard and Navy patrol boats while cutter Minnetonka drove off another. This action was the largest naval engagement of the Vietnam War.

Coast Guard cutters made a vital contribution to the Navy’s effort to limit coastal infiltration, forcing the communists to use the Ho Chi Minh Trail to sustain the insurgency in the South. Wartime statistics show that Coast Guard cutters boarded a quarter of a million junks and sampans and participated in 6,000 naval gunfire support missions causing extensive damage to the enemy. Of the 56 cutters that served in Vietnam, 30 were turned over to South Vietnam and Coast Guardsmen trained their Vietnamese crews to operate the vessels. Former cutters and the Vietnamese who crewed them formed the nucleus of the South Vietnamese Navy for the remainder of the war.

Port Security and Waterways Details and Explosives Loading Detachments (ELDs) also proved important to the war effort. On Aug. 4, 1965, the U.S. Military Assistance Command in Vietnam requested a Coast Guard Port Security Officer for the Port of Saigon and two Coast Guard ELDs. The Coast Guard sent the officer to Saigon and two ELDs, assigning one to Nha Be and the second to Cam Ranh Bay. These ELDs were highly trained in explosives handling, firefighting, port security, and small boat operations and maintenance. The ELDs were authorized to do anything necessary to enforce regulations. ELD personnel also taught U.S. Army and Vietnamese personnel in small boat operation, port firefighting, pier inspection, and proper cargo handling and storage.

In 1966, the Military Assistance Command in Vietnam requested a Coast Guard buoy tender to install, maintain and service aids-to-navigation (ATON) in South Vietnam. Soon, a buoy tender arrived to set petroleum buoys for offloading fuel. In all, five buoy tenders marked South Vietnamese channels and maintained lighthouses along the South Vietnamese coast. Buoy tender duties included marking newly-dredged channels and coral reefs, positioning mooring buoys, and training the Vietnamese in ATON duties. Vietnamese lighthouse service personnel were assigned to temporary duty aboard Coast Guard buoy tenders that reactivated and automated all South Vietnamese lighthouses.

The service built and manned Long Range Aids to Navigation (LORAN) stations allowing mariners and aviators to accurately fix their positions. LORAN’s original purpose was to provide electronic aids to mariners and aviators in areas where surface aids were nonexistent, waters relatively uncharted, or skies frequently overcast. Under Operation “Tight Reign,” LORAN stations were established at Con Son Island and Tan My in Vietnam; and at Lampang, Sattahip and Udorn in Thailand. Tight Reign continued until April 29, 1975, a day before the fall of South Vietnam, when the station at Con Son Island discontinued operations.

The escalation of the Vietnam War meant that supplies had to be transported by ship, which increased the need for merchant vessels under Military Sealift Command (MSTS) contracts. Merchant officers and shipping companies complained about the lack of a Coast Guard Merchant Marine Detail and, in August 1966, MSTS requested a Merchant Marine Detail. By December, a marine inspection officer was assigned to Saigon. Merchant Marine Detail personnel kept merchant vessels in theater moving by providing diplomatic, investigative and judicial services. Coast Guard officers assigned to Merchant Marine Details had the authority to remove sailors from ships, order violations corrected, or stop a ship from sailing.

Coast Guard aviators participated in the Coast Guard-Air Force Aviator Exchange Program. Two Coast Guard C-130 pilots took part in the program, but the rest of the aviators were HH-3 helicopter pilots. In the spring of 1968, the service assigned the first of many Coast Guard helicopter pilots to the Air Force’s 37th Aerospace Rescue and Recovery Squadron at Da Nang. The resulting honors and awards presented to Coast Guard aviators included four Silver Star Medals, 15 Distinguished Flying Crosses, and 86 Air Medals.

Today, over 50 years after the service joined the fight in Vietnam, we commemorate the Coast Guardsmen who went in harm’s way, several of whom paid with their lives in a land far from home shores. In all, 8,000 Coast Guardsmen served in Vietnam. Their efforts curtailed maritime smuggling and enemy infiltration, saved hundreds of lives, and proved vital to the war effort in Vietnam.

      Most people were not aware of the coast guard activities beyond our borders. They tend to do their job and not boast or brag. So we brag about them on this blog.
