The range consists of 6 remote towers arranged in a rectangle, with 2 master stations in the center of the northern and southern halves of the range. The two master towers and R2 are 4-legged platforms. There are two decks on the towers; the instrument deck is approximately 70 feet above water and holds a large environmentally controlled room, a diesel generator, and a photovoltaic cell array. The helicopter deck is 20 feet above the instrument deck, and extends 50 feet beyond the instrument deck to the north. It is large enough to hold two helicopters. The 100 foot communications tower is on the south end of the helicopter deck, and two 20 foot extensions hold wind generators.
The other towers are 3-legged platforms. The instrument deck is smaller on these rigs and holds only the photovoltaic array. The helicopter deck is of similar size but presently there are no wind generators at these towers. Communications electronics are housed in a large shed on the helicopter deck. On most of the 3-legged platforms the communications tower is 50 ft tall.
