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. The Iwo Jima LORAN-C transmitter had a transmission power of 4 megawatts, which is more than the most powerful broadcasting stations. The Iwo Jima LORAN-C transmitter had a 411.5 meter (1350 ft) tall guyed mast, which was built in 1963. A guy wire insulator eyebolt failed sending the insulator crashing into the tower, knocking it out of plumb. It collapsed in 1964 on repair of the structural damage caused by the insulator. The collapsing tower killed four construction contract workers, three on the tower and one on the ground. The collapse also destroyed the transmitter building.
