Joint Soviet/American Loran operations: the Bering Sea Chain

The US Coast Guard entered into an agreement with the Soviet Union for the implementation of a mixed Loran-C/Chayka chain in the North Pacific. The similarities and differences of the US Loran-C and USSR Chayka systems are discussed, and the agreed-on design for a Bering Sea Chain is presented. The chain will provide marine and aviation coverage over the five-hundred-mile-wide coverage gap that exists in the North Pacific between the North Pacific chain and the Northwest pacific and Soviet Eastern USSR chains.<
