1961: Detachment Kilo of NMCB 14 arrived in Holy Loch, Scotland. The Seabees had come for the purpose of erecting a floating dry dock, capable of docking Polaris submarines. A floating dry dock had not been erected since the end of World War II. The dry dock to be installed at Holy Loch was of World War II-vintage and had been kept in mothballs since the war. When it was decided that an overseas repair facility for Polaris submarines was a strategic necessity, the dock was reactivated and towed from Green Cove Springs, Florida, to Holy Loch, Scotland. To complete the dry dock, the Seabees’ major tasks consisted of placing 22 mooring legs weighing approximately 1,000 tons each, jacking eight wing-wall structures weighing 450 tons each to a vertical position, erecting more than 825 feet of steel structure to support cranes weighing 240 tons, and welding four dock sections. In addition, Seabees installed electrical, plumbing and interior communication systems. Other projects included erecting living and office spaces, and painting the exterior and interior of the dry dock.

1943: ACORN 8 arrived at Noumea. Later moved to Guadalcanal, Munda and Russells for restaging and then on to Biak. (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each ACORN to maintain the base after initial construction was completed and the construction battalion had been withdrawn. During the war, ACORNs were sent to such places as Guadalcanal, Espiritu Santo, Green Island, Rendova, Treasury Island and Majuro.)
1944: The versatile match of Seabee and bulldozer is an image which will never be forgotten by citizens of Falmouth, England. When a German air strike exploded a fuel dump and sent a river of flaming gasoline flowing downhill toward the town, Seabee Philip Bishop, NMCB 81, quickly bulldozed a dam which stopped the channel of fire and saved the community from destruction. The bulldozer-fireman received the British Empire Medal (Military) and the enduring gratitude of an English seaport town.
