Over the years it was continuously upgraded for fleet HF and LF communications. The Very Low Frequency (VLF) transmitter and antennas were constructed during the Cold War for communicating with our submarine fleet. Satellite communications made it obsolete and no longer needed. I thought they still had some VLF stuff. I remember they were protesting in Alaska because there was some kind of array up there (HAARP?). This array was supposed to be capable of talking to a sub under the polar ice. They said it was screwing up the Caribou and Polar Bears, maybe even altering human DNA or some other horrible thing. There were signs hanging around everywhere once you got out of Anchorage. There are several Navy VLF transmitters still in operation according to Wiki There's one in Cutler, Maine, another in Washington state, one in Australia and another in Hawaii. The one in Australia is no longer operated by the US or Australian Navy. It's operation has been subcontracted to Raytheon Australia. I spent a total of four years at two different transmitter sites with VLF equipment. The one in Ponce, Puerto Rico and the one in Annapolis have since been decommissioned. They shut down the one in Alaska too. That was far more than a tall tower tho. This was acres of antenna. Most of those sites also had Low Frequency and High Frequency transmitters and the necessary antennas for them. The one in Puerto Rico had many in addition to the VLF transmitter. Same with the one in Annapolis, MD. I forget exactly how many but I remember at least 15 to 20 HF transmitters and maybe about 10 Low Freq transmitters. More transmitters than antennas but there was a big board where you could patch a particular transmitter to a particular antenna. |
