1945: ACORN 50 was decommissioned and Naval Air Base Kobler was commissioned. 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each ACORN to maintain the base after the initial construction was completed and the construction battalion had been withdrawn.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.

1966: A Naval Support Unit of Seabees was established in the Department of State. This assignment came about in 1964, because cleverly concealed microphones and listening devices were discovered in the United States embassy in Moscow. As a result of this discovery, Seabees were sent to the newly built U.S. embassy in Warsaw. They proceeded to tear up floors and walls, and there too discovered ingeniously hidden microphones and listening devices. Consequently, the Department of State decided to use Seabees to keep an eye on foreign contract construction at American diplomatic missions in Soviet-bloc countries and also to perform maintenance duties and minor repair construction. The program was later extended to American diplomatic missions in the Far East and in Africa. These informal arrangements were made more permanent with the organization of the Department of State Naval Support Unit.

1969: Cmdr. R.D. Gaulden, Civil Engineer Corps (CEC), commanding officer of NMCB 4, relieved Cmdr. J.J. Lee, CEC, commanding officer of NMCB 12 at Camp Adenir, Da Nang, RVN.

1971: NMCB 3 main body flights, consisting of three passenger flights and one cargo flight, departed Da Nang, RVN, for Port Hueneme, California.
