ACORN 1 dissolved. (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each ACORN to maintain the base after the initial construction was completed and the construction battalion had been withdrawn.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.)

1943: This photograph shows Seabees with Construction Battalion Detachment 1006 crossing the Mediterranean onboard LST 388 taking part in the Sicilian Invasion. Causeways that aided the troops ashore can be seen as they are strapped alongside the LST. Pontoons and causeways, a new invention at the time which had yet to be tested in wartime efforts, were about to make their debut in the Atlantic Theater. This was the first use of causeways in war and showed there versatility and indispensability in amphibious landings. CBD 1006 also took part in the Normandy Invasion in June 1944.

In Korea, a detachment from Amphibious Construction Battalion (ACB) 1 landed behind enemy lines on the island of Yo. There they built an emergency landing airstrip for crippled U.S. Marine aircraft. The planned 2,400 foot runway had been estimated to be a 45-day project. The Seabees finished it in 16 days.
Just before midnight on June 9, 1965, an estimated 2,000 Viet Cong launched an attack upon the still unfinished U.S. Special Forces camp at Dong Xoai in the Republic of Vietnam. The men of Seabee Team 1104, who were building the camp, joined with a small detachment of U.S. Army Special Forces and 400 RVN irregular forces to put up a heroic defense. At daybreak on June 10th, human wave attacks of Viet Cong made further resistance impossible, so the surviving defenders were evacuated by helicopter.

An NMCB 5 patrol, patrolling the area south of Sector II on the Dong Ha Combat Base, RVN, set off an explosive device resulting in the injury of one member of the patrol, Builder (Heavy) 3rd Class T.L. Richart.
Camp Peary, Magruder, Virginia disestablished.
The first Seabee killed in action in Vietnam, Steelworker 2nd Class William C. Hoover, was killed at the Battle of Dong Xoai. Although wounded in the initial Viet Cong mortar barrage, Hoover quickly went to his assigned defensive post and began firing at the enemy. He was subsequently killed in the fighting. For his heroism, Hoover was posthumously awarded the Bronze Star. Also killed in the battle was Construction Mechanic 3rd Class Marvin C. Shields, the first Seabee to receive the Medal of Honor. Both men were members of Seabee Team 1104.

In Costa Rica, three members of a detachment from Mobile Construction Battalion (MCB) 1 saved the lives of three Costa Ricans who were stranded by a six-foot-deep mud flow during a flood control project. No deaths or injuries were reported and property damage was light in the San Jose and Cartago area, where a flood in December 1963 had left nearly 5,000 homeless.

Operation Forager, as the Marianas campaign in World War II was named, began on June 15, 1944, when 20,000 Marines and Seabees were put ashore on the beaches of Saipan. Seabees of the 121st NCB formed the shore party on the main invasion beach. By June 18, Marines captured Aslito, the main Japanese airfield on Saipan, and that very day, Seabees went to work repairing the bomb damage to the runways. Four days later, the first American fighter planes landed on the strip, and four months later, the Seabees had lengthened and widened the runways so that B-29s could take off for their first bombing of Japan. Japanese troops counterattacked against Aslito airfield and halted the Seabee construction work, but the Seabees grabbed up their arms and held them off. By July 9, Saipan was secured.
The 18th NCB inactivated at Tinian; 45th NCB inactivated at Camp Parks, Shoemaker, California.

On the island of Luzon, Philippines, Mount Pinatubo erupts, destroying Clark Air Base and burying Naval Station Subic Bay and Naval Air Station Cubi Point in a thick layer of ash. In the ensuing Operation Fiery Vigil, members of NMCBs 3, 4, 5, and CBMU 302 work to clear the naval facilities. By October 1991, the Seabees moved 251,000 tons of ash from over 50 miles of paved surfaces.

June 9-25 1952: Operation Crippled Chick
One of the most incredible Seabee feats of the Korean War took place on the small island of Yo Do in the Bay of Wonsan. In communist hands again in 1952, Wonsan was a key supply and transportation center for the enemy. As such, carrier-based aircraft strikes against Wonsan and points deeper in the interior were numerous and constant. Planes were hit by enemy fire daily leaving their pilots with the unhappy choice of either ditching at sea or attempting to land in enemy-held territory. The need for an emergency airstrip was critical and, under the code name Operation Crippled Chick, a detachment of Seabees came to the rescue. Put ashore on Yo Do Island, they were given 35 days to construct a runway. Working under constant artillery bombardment from neighboring enemy positions, they managed to complete the 2,400-foot airstrip in only 16 days. By a prearranged signal, "Steak is Ready," the Seabees signaled that the job was done, and nine damaged aircraft landed on the new field that same day.
