The United States Navy Construction Battalion, also known as the "Seabees," has a motto that is representative of their story since the days of World War II. The Seabee motto is:

"We build, we fight."

History of the Seabees

The Navy Construction Battalion, whose abbreviation "CB" became its nickname, was established in 1941 after the attack on Pearl Harbor. In its early years, Seabees were under the Navy's civil engineer corps and were recruited from construction trades. 

Primarily utilized as builders, Seabees played a major role in World War II, and later in the Korean War, where they landed at Inchon with assault troops. Seabees built causeways in Korea just hours after their initial landing.

Between 1949 and 1953, Navy CBs were divided into two units: amphibious and mobile battalions. The Navy calls their enlisted jobs ratings. Similar ratings are placed in various communities.

After World War II, the need for such trained forces was considered a priority by the Department of Defense, and between 1949 and 1953, Naval Construction Battalions were organized into two types of units: Amphibious Construction Battalions (PHIBCBs) and Naval Mobile Construction Battalions (NMCBs). There are also Naval Underwater Construction Teams that are also trained divers who secure piers and perform welding underwater when required. 

Duties of Navy Seabees

The work and responsibilities of Seabees cover a wide range. That may include work like grading an airstrip, conducting soil tests for an amphibious landing zone, or building a new barracks facility. 

There are several ratings under the Construction Battalion community, and in addition to being crucially important to the day-to-day operations of the Navy, these jobs are good training for post-military construction careers. Seabees include builders, construction electricians, construction mechanics, engineering aid, equipment operators, steelworkers and utility workers. The ratings or jobs that comprise the Seebee team are varied.
