The United States Army Signal Corps established Camp Murphy, a top-secret radar training school in 1942.

Camp Murphy was located between Stuart and Jupiter in what is now Jonathan Dickinson State Park in Martin County in southeastern Florida.

[1] The post was named in honor of Col. William Herbert Murphy, a pioneer in the development of radio beams and equipment for military aircraft.

One of the vault doors apparently had to be forced open from inside—there is a man-sized hole in the roof immediately above the doorway with the concrete rebar bent inward.

In addition, on the western side of the railroad tracks, the remains of the water treatment facility are still visible, although very run down.

Currently, one of the few buildings still in use is now the "Road to Victory Military Museum", located next to Memorial Park / tennis courts in Stuart.

The park office, located just west of the camp area, was a secret bomb shelter for government persons during the Kennedy administration.
