Iwo Jima LORAN-C transmitter was a LORAN-C transmitter at Iwo Jima, Japan of Grid 9970 at 24°48′8″N 141°19′32″E / 24.80222°N 141.32556°E. Iwo Jima LORAN-C transmitter had a transmission power of 4000 kilowatts, which is more than the most powerful broadcasting stations.
Iwo Jima LORAN-C transmitter had a 411.5 metre (1350 ft) tall guyed mast, which was built in 1963. It collapsed in 1965 at repair trial of a defective eyebolt of a backstage insulator. The collapsing tower killed 6 people and also destroyed the transmitter building. The tower was later replaced by a tower of same height. On September 29, 1993 the Iwo Jima LORAN-C transmitter was transferred from the U.S. Coast Guard to the Government of Japan. In 1994, the transmitter was shut down, and its tower was demolished. The service is now provided from LORAN-C transmitter Niijima.
