Kwajalein Atoll is part of the Republic of the Marshall Islands (RMI). The southernmost and largest island in the atoll is named Kwajalein Island, which its majority English-speaking residents often use the shortened name, Kwaj. The total land area of the atoll amounts to just over 6 square miles (16 km2). It lies in the Ralik Chain, 2,100 nautical miles southwest of Honolulu, Hawaii.
The Battle of Kwajalein was fought as part of the Pacific campaign of World War II. It took place 31 January – 3 February 1944, on Kwajalein Atoll in the Marshall Islands. Employing the hard-learned lessons of the Battle of Tarawa, the United States launched a successful twin assault on the main islands of Kwajalein in the south and Roi-Namur in the north. The Japanese defenders put up stiff resistance, although outnumbered and under-prepared. The determined defense of Roi-Namur left only 51 survivors of an original garrison of 3,500.

US Naval Advance Bases were built globally by the United States Navy during World War II to support and project U.S. naval operations worldwide. A few were built on Allied soil, but most were captured enemy facilities or completely new. Advance bases provided the fleet with support to keep ships tactically available with repair and supply depots of facilities, rather than return them to the continental United States. Before Japan declared war on the United States the U.S. Navy had a single fleet-sized advanced base in the Territory of Hawaii at Naval Station Pearl Harbor. During the war the U.S. Navy Seabees built over 400 advance bases categorized by size. Naval bases were either Lions or Cubs while airfields were either Oaks or Acorns. Lions and Oaks were major facilities while Cubs and Acorns were minor. PT Boats typically would get a Cub and airfields with single runways were Acorns. The larger bases could do refueling and overhaul; loading of troopship and cargo ships; and preparing amphibious assault ships. Some became major repair depots. The Seabees developed auxiliary floating drydocks were able to repair battle damage and do regular maintenance in the field saving ships trans-pacific trips for repair. A few bases also were developed to be R and R for all U.S. personnel. Most Advance Bases were built by the US Navy's Seabees in Naval Construction Battalions (CBs). At the start of the war civilian contractors were employed in construction. The Seabees in World War II built most of the airfields used by the United States Army Air Forces and United States Marine Corps, as they had the ships and cranes needed to transport the vast amount of equipment needed at the advance bases. The US Army and United States Coast Guard also operated out of many of these facilities. Seabees could build new or repair damaged runways, and with advancements in heavy bomber technology lengthen runways as needed. A few Naval Advance Bases were built for the Korean War and Vietnam War.
Naval Base Saipan or Naval Advance Base Saipan or Naval Air Base Saipan was a United States Navy Naval base built during World War II to support Pacific Ocean theater of war and the many warships and troops fighting the war. The base was on the island of Saipan in the Northern Mariana Islands. The base was part of the Pacific island hopping campaign. The base construction started after the Battle of Saipan ended on July 9, 1944. US Naval Advance Base Saipan was constructed by the Seabees Naval Mobile Construction Battalions. The base was under the Commander Naval Forces Marianas. Saipan is 12 miles (19 km) long and 5 miles (8.0 km) wide. About 70% of the island was sugarcane cultivation at the start of the base construction. At the start of the Battle of Saipan, the island's population had about 30,000 Japanese troops and about 20,000 Japanese civilians. The city of Garapan was the administrative center for the Saipan governmental district.
Tinian Naval Base and Naval Air Facility Tinian was a major United States Navy sea and air base on Tinian Island, part of the Northern Mariana Islands on the east side of the Philippine Sea in the Pacific Ocean. The base was built during World War II to support the many bombers and aircraft fighting and patrolling in the South West Pacific theatre of the Pacific War. Numerous naval facilities were built on the entire island of 101.22 km. The main port was built at the city and port of San Jose, also called Tinian Harbor. All construction was done by the Navy's Seabees Sixth Construction Brigade with minor help from the 64th Army Engineers, including the main two airports: West Field and North Field. United States Army Air Forces operated long-range bombers out of the air base built and maintained by the Seabees. The base was decommissioned on 1 June 1947.
Naval Base Abemama was a naval base built by the United States Navy in 1943 to support the World War II effort. The base was located on Abemama atoll, also called Hopper Atoll, in the Gilbert Islands in the Central Pacific Ocean. The base was built as one of many advance bases in the island-hopping campaign towards the Empire of Japan. At Naval Base Abemama the Navy built a seaport and airbase. Construction started after the Battle of Abemama ended November 24, 1943, part of Operation Galvanic.
Naval Base Kwajalein was United States Navy base built on Kwajalein Atoll, in the Marshall Islands to support the World War II efforts in the Pacific War. The base was built after the Battle of Kwajalein ended 3 February 1944. The US Navy built airfields, a seaport and a craft repair depot on the captured islands. The base was part of the vast Naval Base Marshall Islands.
Naval Base Majuro was a major United States Navy base built on Majuro Atoll, in the Marshall Islands to support the World War II efforts in the Pacific War. The base was built after the Battle of Majuro-Kwajalein ended 3 February 1944. Majuro was found to be unoccupied and abandoned when the United States Army arrived. The US Navy built airfields, seaport, and other facilities on the captured islands. The base was part of the vast Naval Base Marshall Islands.
Naval Base Marshall Islands were United States Navy advance bases built on the Marshall Islands during World War II to support the Pacific War efforts. The bases were built by US Navy after the Marshall Islands campaign that captured the islands from the Empire of Japan. By February 1944 the United States Armed Forces had captured the islands. Most of the airfields and other facilities Japan had built were destroyed in allied bombing raids and naval bombardment. US Navy Seabee Construction Battalions arrived as soon as the area was secured and remove the debris. The Seabees quickly repaired, built and improved the airfield/runways and seaport. Seabees often worked around the clock to get airfields operational so that fighter aircraft and bombers could start operating. The bases were used for staging upcoming campaigns and for repair.
