SCR-602

The SCR-602 (Set Complete Radio model 602) also known as the AN/TPS-3, was a mobile, lightweight, medium-range, early-warning radar utilized by the United States and its allies during World War II. The radar was originally designed for use during the initial stages of an amphibious assault or military operation where its lightweight relative to other radar systems was a distinct advantage. Once larger radars such as the SCR-270 or AN/TPS-1 came online the SCR-602 could also be used to fill in gaps in radar coverage.

Numerous variations of the SCR-602 were manufactured during the war. It was utilized by the United States, United Kingdom and Australia.

Developing the radar

Development of the SCR-602 began in 1942 at the behest of Colonel Gordon P. Saville of the United States Army Air Corps. With delays to the manufacture and fielding of both the SCR-588 and SCR-527, the Air Corps was quickly seeking another radar for ground-controlled interception. This new radar was an adaptation of the United Kingdom's Chain Home Low radar.[1][2]

Technical description

The radar utilized the BC-800-B IFF receiver/transponder.[3]

Operational history

The SCR-602 was developed in time to be utilized by the U.S. Army during the invasion of North Africa in November 1942.
