The radars in the 1955 photo above, from left to right, were: AN/MPS-7 (mobile AN/FPS-3); AN/TPS-10; AN/MPS-11 (mobile AN/FPS-8 or AN/GPS-3); and AN/MPS-14.

Compare the 1955 photo (top) to the 1964 photo (above) -- you can see all the old temperate-tower foundations in a line between the AN/FPS-20 (-67) tower and the AN/MPS-14 tower.

In the photo above, taken in 1978, the yellow concrete blocks in the center of the photo -- which I earlier mistook to be the footings for the former AN/MPS-14 tower -- appear in fact to have been the footings for the AN/MPS-11 tower.
