Faleu Island is a small Island located to the east of the South Passage in Truk Lagoon in Chuuk State (Truk) in the Federated States of Micronesia.
Occupied by the Japanese.
Faleu island guarded the strategic southern pass into the anchorage and was the control center for the Japanese Navy's underwater detection systems. Underwater detection coils were present here, to sense magnetic of passing ships. This coil was 4.5m loops and one 750m x 150m loop, marked by two bouys, connected by cable to Faleu Island. By 1943, the detection system was fully implemented and remained in operation until the surrender in September 1945.
During the war, two 150mm (5.9") guns were emplaced in open pits covering southward with concrete ammunition magazines. Also a 1.5m range finder and 90cm searchlight on a 6' tower, with sound loactor was emplaced nearby. Thirty men of the 41st Naval Guard Force were stationed on Faleu. 15 mines were installed on the west side of the island, the other 135 were destroyed in an Allied bombing raid before being installed. Other frame construction buildings on the island included a command post, barracks, revetted generator, shrine, underground water reservoir,
latrine, water distillation plant, bathhouses, mess hall and kitchen.
