1973: As part of Operation Deep Freeze 73, Seabees deployed to Antarctica to construct the six-story high Geodesic Dome at South Pole Station. The Antarctic deployment of Naval Mobile Construction Battalion (NMCB) 71 resulted in the completion of the Siple Station project, erection of the Geodesic dome and other structures at the South Pole, as well as completion of numerous projects in the McMurdo Station area. The Geodesic dome covered and protected most of the buildings at South Pole Station. Above, the Caterpillar LGP D-8, custom built by Cat for Operation Deep Freeze. Specs included 54″-wide track pads, 16′ 10″-wide dozer blade, lengthened frame and ground pressure at only 3 psi. Seabees working bare-chested in the snow may have seemed strange. However, when the temperature rose above 0 degrees F and the wind was calm (as it often was in mid-summer) the sun was so intense that working shirtless was the preferred option.

An explosion heavily damaged the barracks where the Construction Battalion Maintenance Unit (CBMU) 302 detail was quartered. The explosion was followed by small arms fire from Viet Cong infiltrators on the base. Three CBMU 302 personnel were wounded. Chief Equipment Operator Sears was critically injured, while Construction Electrician (Telephone) 3rd Class Snyder and Culinary Specialist 2nd Class Turnage suffered light to moderate injuries.

1943: Seabees of the 19th NCB joined the First Marine Division in the assault on Japanese-held Cape Gloucester, New Britain. During the battle, Seabees bulldozed paths to the Japanese lines so that American tanks could attack hostile positions. By New Year’s Day, the Japanese airstrips were captured. However, during this first week, continuous enemy air raids resulted in five men of the battalion killed and 24 wounded.
1944: CBMU 629 was split into four detachments of one officer and six men each. Three of the detachments worked with small boat units in their preparation for the Rhine River crossing, and one of the detachments worked with an Army Engineer unit. The first detachment became the first Seabee unit to enter Germany on 26 December. Later, they assembled pontoon barges on the Rhine at Remagen. These barges were to be used in connection with strengthening the Ludendorff Bridge. When that structure collapsed, work on the barges stopped.
Dec. 26-31, 1956: California has been a frequent beneficiary of Seabee firefighting forces. Forest and brush fires have been a special hazard during the state’s dry season. Seabees from the Naval Construction Battalion Center (NCBC), Port Hueneme, California, manned the fire lines in the Malibu Canyon – Zuma Point area and helped contain one of the worst brush fires in California history. Seabees fought the blaze alongside civilian firefighters. In addition, Seabees were busy putting out small fires that cropped up along the highway, digging trenches, cutting fire breaks in the valley and gulleys surrounding the Zuma Mountain Range, helping residents protect their homes from the ravenous flames.
