Silver Creek's radio tower was a mast radiator insulated against ground, which provided VLF communication to ground and mobile nuclear missile facilities during the Cold War. It transmitted at a maximum power of 110 kW. The facility was partially built into the ground and was designed to withstand a moderate nuclear blast from a distance of 10 miles. The facility was self-sustaining and employed a sophisticated ventilation system as well as backup diesel generators.
