Constructed and transferred for use on 11 Apr 1944 as Fort San Jacinto WWII CCR-582 Radar Site. Construction costs to date of transfer were $28,614.74. The physical plant consisted of a radar set, usually mounted atop an existing building or tower, a powerhouse with two generators and a 1000 gallon fuel tank. The powerhouse was placed on a concrete pad and footings installed by the Corps of Engineers who erected the structure.

The radar equipment was installed by the Signal Corps. It required 3.7kW of 120/240 AC, 1 phase, 60 cycle power furnished by commercial power backed up by the two on-site generators. The two 5 kW generators were furnished and installed by the Signal Corps.

Site Operation

In operation, the SCR-582 search radar provided an overview of all potential targets within its range. Once enemy targets were identified and plotted at the harbor HECP/HDCP command posts, target assignments were passed by telephone to the appropriate SCR-296 tracking radar site, citing the approximate range and azimuth of the target. Each gun battery 6" or larger had an associated SCR-296 radar site to track specific targets. The SCR-296 radar operators would then find the assigned target and pass the precise range and azimuth to the plotting room at the gun battery by phone. The radar operators would continue to track the target and update the plotting room as the range and azimuth changed.
