August 15

1942: 19th Naval Construction Brigade (NCB) established at Camp Bradford, Norfolk, Virginia.
1944:  Invasion forces landed on Guam in the Marianas Islands, July 21. The initial objective was to take possession of Apra Harbor, together with the surrounding development area and airfield on Orote Peninsula. Landing forces struck north and south of the harbor. Seabees participated in the assaults: the 25th and 2nd Special NCBs on the beaches north of the harbor, and the 53rd and 13th Special NCBs, and CBMU 515 on the southern beaches. For three weeks, combat and construction continued until finally, on Aug. 10, Japanese resistance ended. Since considerable development had been planned for Guam, the 5th Naval Construction Brigade was established. The brigade assumed control of the construction and development of base facilities for both the Army and Navy. Guam became a great Army air base, as well as the principal naval base in the Western Pacific.

1969: Hurricane Camille wreaked havoc on the residents of the Mississippi Gulf Coast. In her trajectory across the Gulf Coast, she destroyed or damaged 30,000 homes and hundreds of business, civic and religious structures, severed communications, and knocked out water, power and sewer service. At Naval Construction Battalion Center (NCBC) Gulfport, 29 buildings were destroyed and more than 90 percent of the structures were damaged. However, after the eye of the hurricane passed over the Gulf Coast, Seabees implemented a massive mobilization effort to assist the surrounding community in recovery operations. Seabees cleared roads, located bodies, rescued survivors, restored water, gas and electrical power, put out fires, set up mobile dispensaries, and unloaded food, supplies and medicine. On October 31, the Center s military population was awarded the Navy Unit Commendation for exceptionally meritorious service before, during and after the devastating hurricane. In addition, there were numerous individual awards to military and civilian personnel at the Center.
