1943: ACORN 2 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each ACORN to maintain the base after the initial construction was completed and the construction battalion had been withdrawn.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.)

1944: 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.
