The complete Majuro Airfield became home to a number of units: two Marine dive-bomber squadrons, half a Marine patrol squadron, and staging a United States Army Air Forces fighter group.

The Majuro Atoll offered excellent fleet anchorage in the large protected lagoon.

The water was stored in a system of tanks and plumbing with a total of 180,000 gallons for all the islands in the base.

Seabees used coral to pave 10 miles of road and the top of 11,000 feet of causeways, making Delap-Uliga-Djarrit.

For the troop barracks, mess halls, bomb-proof shelters, and recreation facilities were constructed by the Seabees.

Almost all of Dalop Island was taken up by the airfield, so the islets of Uliga, Laura, Rairok, and others of the Majuro Atoll were used.

On V-J Day, surrender of Japan on 2 September 1945 the base was still in full operation.

The Seabees constructed two 750-man camps, shops and storage facilities for the United States Marine Corps.

The Navy decided to place a pool of fighter planes ready to replace losses on Aircraft carrier at Naval Base Majuro.

As Majuro Airfield did not have the space for the new air base, Seabees built a new 4,000 foot by 175-foot runway on Uliga Island.
