Lat 9° 23' 49N Long 167° 28' 15E  Roi-Namur Island is located on the Northern Atoll in Kwajalein Atoll. The island is approximately one square mile in area s formally comprised of Roi Island to the west and Namur Island to the east.

Wartime History
Occupied by the Japanese, Roi and Namur were connected by a narrow neck of land and a causeway.

American missions against Roi-Namur
December 21, 1943–February 1, 1944

American Occupation
On February 2, 1944 during "Operation Flintlock" American forces landed at Roi and Namur and secured the islands in only eight hours. Lt. Col Aquilla James Dyess earned the Medal of Honor posthumously, leading his troops in an advance. After the American occupation, U. S. Navy SeaBees filled in the area between Roi Island and Namur Island, forming Roi-Namur by December 1944.

Built by the Japanese, captured by American forces in February 1944. Still in use today.

Japanese Installations
Many of the Japanese installations have been left standing and are preserved for residents and visitors. Several large cement blockhouses used for munitions and fuel storage. Air headquarters building is testament to the furious battle. Its cement roof shows evidence of bomb and projectile damage from guns of many sizes. Many pillboxes are around the island and several bomb shelters.

Japanese hospital
Near the modern ALCOR Radar station is the remains of a Japanese hospital, with a corrugated tin roof. It is completely overgrown. Inside are remains of examination tables, gas canisters and sheets of X-ray film.

Shallows near the reef
All the war related wreckage was bulldozed onto the reef. Often rusted remains are washed ashore. It is not difficult to find coins, dog tags, bottles, knives and ammunition washed onto shore. Of the many Japanese planes destroyed on the ground during US air strikes, little remains, except for some debris that have been heaped into the shallows. The only recognizable portion is the wing section of a Val in about 3 feet of water off the end of the runway.  Off near the runway are the corroded remains of a landing craft in the shallows of the reef.

Aircraft Dump Area
A large group of aircraft were dumped between North Pass and Mellu Island. The aircraft rest on a sandy bottom at a depth of 30' to 130'. The aircraft include over a dozen F4F Wildcat fighters, SBD Dauntless dive bombers and other types of aircraft. All the aircraft were partially stripped of parts before they were dumped by American forces. These aircraft have no external damage and were likely dumped as surplus or war weary. Today, the aircraft form an artificial reef for coral and fish life.
