The SCR-584 was first used in combat at Anzio in February 1944, where it played a key role in breaking up german air attacks on the confined beachhead. Employed in England against the German V1 flying bombs it achieved remarkable success.

SCR-584 Mobile Short Range Auto Tracking Radar Set - A Mobile Short Range Auto Tracking Radar set built by Westinghouse, General Electric and Chrysler during World War II. Initially developed by the MIT Radiation Laboratory as a gun laying radar using recently developed 2J32 magnetron tube as a microwave power source. The set operated on four frequencies between 2,700 and 2,800 MHz.

The set had a search mode with a range of 40-50 miles and could switch to automatic tracking mode when the target reached within 18 miles. When in the tracking mode target data could be fed to position a nearby anti-aircraft gun battery. The set also presented azimuth and angular height to searchlight control station for directing searchlight as well as transmitting present azimuth, angular height, and altitude to M-4, M-7, or M-9 directors for gun-laying.

The set was self-contained, built on a K-78 trailer and meant for forward area deployment. Its gross weight was 10 short tons. The overall length was 19.5 feet, width was 8 feet, height 10 feet, 4 inches. A towed trailer contained a generator power source. Thirteen men could install the set and obtain approximate data in 2 hrs. Accurate orientation and alignment took 4 additional hours.

The SCR-584 was first used in combat at Anzio in February 1944, where it played a key role in breaking up german air attacks on the confined beachhead. Employed in England against the German V1 flying bombs it achieved remarkable success.
