The USS Holmes County (LST-836) served the United States Navy in four wars: World War II, the Korean War, the Cold War atomic arms race, and the Vietnam War. She was later transferred to the Singapore Navy.

World War II

Landing Ship Tank, LST-836 was laid down on 11 September 1944 at Ambridge, PA., by the American Bridge Company. She was launched on 29 October 1944 in time for duty in World War II. She was assigned to the Asiatic-Pacific theater where she served admirably, ferrying troops and equipment throughout the area of operations. She prepared to do battle in the Marshalls and Carolines until she departed for Okinawa on 12 April 1945. The battle for Okinawa was well underway when she arrived to unload troops and equipment. She returned to Ulithi Island on 29 April where she continued to shuttle troops and equipment throughout the Asiatic-Pacific operating theater. She earned a battle star for her participation in the assault and occupation of Okinawa Gunto in April of 1945. After VJ day, LST 836 was assigned to support General McArthur's occupation forces in Japan. She returned to San Francisco, California on 19 January 1946 and remained on the West Coast for the remainder of this phase of her career. She was decommissioned at Vancouver, Washington and assigned to the Pacific Reserve Fleet on 25 July 1946.

Korean War

LST-836 saw extensive service in the Korean War after being re-commissioned on 3 November 1950 at Bremerton, Washington. She arrived in Yokosuka, Japan on 28 March 1951 and began her service supporting the United Nations forces in their struggle to stop Communist aggression in South Korea. For over eight months, she ferried equipment, supplies, and troops between Japan and various Korean ports. She returned briefly to San Diego, California in early 1952 where she underwent a minor overhaul. She departed 24 July for operations in the Marshall Islands in support of Operation Ivy. After her duties supporting the scientists in the Pacific Proving Grounds, she returned once again to San Diego, California for a brief rest. She sailed on 16 March 1953 to rejoin the still raging Korean War. She arrived in Yokosuka on 22 April, 1952 and immediately began cargo runs from the staging areas to Inchon, Korea.

After the bloody fighting came to an end in Korea, LST-836 stayed in the Far East, transporting cargo in support of UN peacekeeping forces stationed in Korea. She made three Western Pacific (WestPac) cruises and participated in training operations along the West Coast of the United States from 1954 through 1958..

She earned three battle stars during her time in the Korean War.

Operation IVY: Mike and King Shots

LST-836 joined Operation Ivy in August of 1952 being part of Task Group 132.31 (transport element). Operation Ivy was part of the United States Atmospheric Nuclear Weapons Tests conducted by the Department of Defense and the Defense Nuclear Agency. Two nuclear devices, designated Mike and King, were detonated at the Atomic Energy Commission's (AEC) Pacific Proving Ground (PPG) at Enewetak Atoll in the fall of 1952. 

Mike was detonated on the surface on 1 November 1952 at Eluklab Island and yielded 10.4 Megatons. Mike was the first nuclear fusion device ever deployed. King followed on 16 November, 1952 and was an air burst at 1, 480 feet over the reef off of Runit Island. It yielded "only" 500 Kilotons and was the most powerful fission weapon ever detonated. One kiloton equals the approximate energy release of the explosion of one thousand tons of TNT. A megaton is the equivalent of one million tons of TNT.

Temporarily assigned to Commander Escort Destroyer Division 11, LST-836 operated in the forward area of IVY, arriving on 12 September 1952 with a compliment of 6 officers and 123 enlisted men. Designated Task Element/Unit 132.31.1, LST-836 was on independent duty at Bikini Atoll assisting construction during the Mike and King shot preparation. She primarily acted as a transport shuttle between Enewetak and Bikini atolls for the construction of Operation Castle facilities on Bikini.

In preparation for the Mike shot, all personnel were evacuated from Enewetak and Ujelang atolls. LST-836 was dispatched to Bikini Atoll to stand by and evacuate task force personnel from the facility should the fallout from Mike become a problem. She was about 195 nautical miles (361 kilometers), bearing 93 degrees from the Mike shot when it was detonated. Mike produced a tremendous fireball followed by a gigantic mushroom cloud. The blast destroyed Eluklab Island, leaving a submerged crater about 6, 300 feet (1.9 km) in diameter and 160 feet (49 meters) deep. According to the official history of Operation Ivy, this hole was "large enough to hold 14 buildings the size of the Pentagon". 

For King, LST-836 was positioned at Eneman Island, Bikini Atoll, again on standby should personnel evacuation be necessary. The King device arrived at 11:30 A. M. on November 16, 1952. It was detonated at approximately 1,480 feet (451 meters) above sea level over the target area (about 2, 000 feet to the North of Runit Island). It is noted that LST-836 "rolled up weather stations following King". 

The official historian for Joint Task Force 132 states that the "King Shot was perhaps more spectacular in many respects than Mike Shot -- due, primarily, to the relatively close distance (approximately eleven miles) of observers to ground zero". The historian further reports that the poor soles designated as observers felt the heat wave generated by the blast almost immediately. They had a close up look of the "growth of the fireball, the development of the cloud-chamber effect, and the formation of the conventional mushroom-shaped cloud". Approximately 45 seconds after the detonation, the shock wave rolled over Parry Island, sounding like "a 90 mm gnu" going off next to the observers. The mushroom cloud that spread over what was left of the island was reported to have reached 67,000 feet with the base at 40,000 feet. It was seen as far away as Japan. 

Damage from KING was observed far to the North of surface zero at Lojwa. The islands brush was scorched, but not burning as was the brush far South on Jinedrol. The blast was so powerful that it displaced tons of sea water, some of which created puddles in the center of Runit.  LST-836 left the Pacific Proving Ground on 21 November 1952 and was released from Operational Control on 10 December 1952.

A Brief Peace

On July 1, 1955, LST-836 was re-designated USS Holmes County (LST-836) after counties in Florida, Mississippi, and Ohio. USS Holmes County was overhauled in the late 1950's. From 1959 through 1964, Holmes County participated in amphibious training in the Pacific as a member of the Pacific Amphibious Force. She primarily operated along the West Coast of the United States and the Hawaiian Island chain. 

Vietnam War

The Holmes County was back in action starting in 1965, performing combat service during the Vietnam War. She departed her base of operations in San Diego on 11 October 1965 and steamed for Southeast Asia. She arrived in Danang in the Republic of South Vietnam on 22 November 1965. She operated there until 1966 when on 29 March, after 89 days in the combat zone, she steamed for Yokosuka, Japan. The ship stayed in Japan undergoing upkeep, preparing for the 5,500 mile journey home to San Diego. As she departed, Holmes County received the following message from the Commander of the Seventh Fleet "As you depart 7th Fleet Intra-Coastal Task Unit, be assured you leave behind an admiration for the extraordinary work you have done this cruise." 

Stateside Again

USS Holmes County (LST-836) arrived in San Diego on 26 May 1966. She operated in the San Diego area for approximately four months, participating in one the largest peacetime operations ever conducted by the Pacific Fleet. Operation "Base Line", however, would not be her last hurrah.

Back to Vietnam

The Holmes County came out of the yards following an overhaul in the spring of 1968.  She operated off the U.S. coast during refresher training and worked with the Marines evaluating a new amphibious vehicle.  The ship then departed San Diego in late summer of 1968 bound for Vietnam.   After arriving in-county in October the Holmes County carried cargo in I Corps  with a few side trips to the Philippines for refitting.   Most of her  work was accomplished  between Danang and Cua Viet on the DMZ.

In early 1969 she sailed once again for Vietnam where, on March 15, she traded crews with the USS Blanco County (LST 344).  The crew in Vietnam was pleased to have a 'new' ship on which to carry on operations in the delta.  

USS Holmes County (LST-836) served with pride in Vietnamese waters until May 10, 1971.  Decommissioned again, Holmes County left the United States Navy to serve in the Singaporean Navy on 1 July 1971. She was renamed RS Endurance (LS201) by Singapore. The Singapore Navy acquired four other former USN "County" class LST ships after the Holmes County was transferred. The Singapore Navy has since decommissioned her.  After more than three decades of service, LST-836 has finally earned the rest.
