A Construction Battalion Maintenance Unit (CBMU) also accompanied each ACORN to maintain the base after the initial construction was completed and the construction battalion had been withdrawn. During the war, ACORNs were sent to such places at Guadalcanal, Espiritu Santo, Green Island, Rendova, Treasury Island, and Majuro.)

1980: The Operation “New Life” camp reached its peak population of 50,233 on this day, after that the pace gradually slackened as the flow of refugees to the states outran the influx of new refugees. By 26 June the camp population had dropped to 10,138 and Operation “New Life” began to wind down.
About Operation “New Life”, on 29 April 1975 the government of the Republic of Vietnam surrendered to the North Vietnamese as North Vietnamese regulars and Viet Cong closed in on Saigon. Before the surrender, President Gerald Ford ordered a mass evacuation of Americans and Vietnamese from the capital. For the latter who were political refugees, it meant the beginning of a long journey to a “new life” in the United States. In addition to the evacuation by air, many thousands of Vietnamese chose to flee the country in ships, and even small boats. The first stop for many on this journey was Grande Island, located at the entrance of Subic Bay, Republic of the Philippines. Here, Seabees, assisted by Marines and civilian employees from the Navy Public Works Center built a tent camp for the refugees. From Grande these refugees moved to the larger camps which had been built on Guam in the Marianas.
On 23 April 1975 the 30th Naval Construction Regiment directed all Seabees on Guam to halt their normal construction projects and mount an around-the-clock effort to prepare facilities to house the approximately 50,000 refugees who were even then fleeing South Vietnam. Seabees first rehabilitated the abandoned Naval Hospital Annex at Asan Point. The Seabees worked around the clock and by Friday, 25 April, the camp received the first arriving refugees and quickly filled to its 10,000-person capacity. On 24 April Seabees began construction of a huge, 50,000 person tent camp at Orote Point. This was a monumental undertaking as it involved clearing the jungle from more than 50 acres of land. Once again, the Seabees worked 24-hours a day and the camp received its first refugees on 26 April. Not only did construction ratings work, but the battalions also pressed their support personnel into action. Supply clerks, mess cooks, and yeoman all pitched in and worked around the clock to get the job done. Construction continued and in about a week, Seabees erected 2,000 tents with no end in sight. Support utilities were also provided: messing facilities and kitchens, thousands of feet of water mains to supply showers and washing facilities, as well as the necessary sanitary facilities.
1944: ACORN 23 dissolved and absorbed into Naval Air Base, Ebeye (Kwajalein Atoll). (Used during World War II, an ACORN was a tailored unit designed to carry out the rapid construction and subsequent operation of a landplane and seaplane advance base. Each ACORN had a construction battalion attached to it, as well as trained personnel to operate the control tower, field lighting, aerological unit, transportation, medical, berthing, and messing facilities. A Construction Battalion Maintenance Unit (CBMU) also accompanied each ACORN to maintain the base after the initial construction was completed and the construction battalion had been withdrawn. During the war, ACORNs were sent to such places at Guadalcanal, Espiritu Santo, Green Island, Rendova, Treasury Island, and Majuro.)

1968: The last flight of NMCB 11’s 16-flight airlift to Vietnam was marred by disaster. The flight crashed on landing at Quang Tri airstrip. Seven passengers were injured and immediately flown by Medevac helicopters to the hospital ship, USS Sanctuary, cruising off the coast of Vietnam. The left wing was torn from the plane on impact and strewn ablaze for several hundred yards from the plane. Fires broke out within the fuselage of the plane, and one of the remaining engines burst into flames. While the crash trucks were rushing to the scene, Seabees poured out of the rear hatches carrying the injured with them. The battalion’s dentist, Lt. Conley T. Snidow, who was accompanying the troops, administered first aid on the scene.
