1944: UDTs, led by Civil Engineer Corps (CEC) officers and mostly comprised of Seabees, began clearing the approaches to Peleliu for an amphibious assault. Three days later, Marines of the First Division came ashore accompanied by Seabees of NCBs 33 and 73, and Construction Battalion Division (CBD) 1054. Initially, CBD 1054 Seabees operated pontoon barges and causeways to assist in the landing of supplies and vehicles, while the Seabees of the 33rd and 73rd worked on the beach unloading cargo. On September 19, however, when the airfield was captured, they began clearing debris from the airstrips. The following day, their construction equipment was brought ashore and the Seabees began making rapid repairs. Only 72 hours later, three squadrons of fighter aircraft were able to land and begin operations. On September 23, the Seabees began constructing a bomber base which, despite land mines and mortar fire, was made operational in seven days.

1944:A naval task force landed the First Marine Division accompanied by Seabees of NCBs 33 and 74, and CBD 1054 on Peleliu, Palau Islands, in the Western Carolines. The island had been subject to air and shore bombardment prior to the landings, while minesweepers and personnel of theUDTs cleared channels and beaches. The UDTs, led by CEC officers, were mostly Seabees. Peleliu marked the first time the Japanese used new tactics to oppose amphibious assaults. The tactics included light resistance on the beaches with heavy counterattacks and a main line of defense inland. Fighting on Peleliu was heavy, because the Japanese had well-prepared positions in caves and tunnels. The island was not secured untilNovember 25.
1945:The 27th NCR was inactivated; the 41st and 59th NCBs were inactivated on Guam.
1950:Seabees of NCB 104, later re-designated as Amphibious Construction Battalion (ACB) 1, participated in amphibious landings with theMarines at Inchon, Korea. Building pontoon causeways and unloading eight tank landing ships carrying supplies into Inchon posed major challenges for the Seabees. Inchon harbor had a fantastic tide, over 30 feet in most places. The tide receded to the main channel and left a vast mud flat in front of the city. Small craft, tank landing ships, patrol craft and other supply vessels were left high and dry on the mud when the tide withdrew. In their usual Can Do spirit, the Seabees had a pontoon causeway built on the second day that allowed Gen. Douglas MacArthur to walk ashore dry-shod, fromUSS Mount McKinley.
1950:NMCB 2 was commissioned.

1945:ACORN 29 decommissioned and absorbed into Naval Air Base (NAB), Yonabaru, Okinawa. (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 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.)
