U.S. Navy to scrap submarine antenna sites

The United States Navy says that it will dismantle two extremely low frequency radio transmission centres used to communicate with submerged submarines.

Two transmitter sites are involved. One is in northern Wisconsin and the other in Michigan. They will go out of service on September 30th but could take up to three years to disassemble and close down permanently.

Each system consists of a transmitter and an antenna strung on 600 12 meter high poles. The navy has used these extremely low frequency transmitters to maintain secure communications with submarines at sea but now will use 12 smaller transmitters, sited worldwide.
