USS Canberra SPQ5 670326
Official period caption: “Super radars (AN/SPQ5) for guidance on terrier missiles installed on board USS Canberra (CAG-2). The radars have massive, turret-like antennae and resemble giant searchlights. Developed for the U.S. Navy by the Sperry Gyroscope Company, the long range, high-altitude missile guidance systems are a part of the U.S. Navy’s program directed toward the fleet with highly reliable missiles to combat supersonic jet aircraft. The super radar is giving exceptionally high performance for tenacious stable guidance of supersonic missiles whether fired singly or in salvoes at individual or multiple enemy attackers. The systems combine many automatic radar functions in each unit and either system can control the missiles from a single launcher or battery, which fires the terrier missile or both radars can track different target groups simultaneously. It also includes flexible modes of scanning the air space many miles beyond the horizon, providing the advantage of early warning. Thus, individual targets can be selected from close flying groups and tracked with great distances while the missiles are launched and guided with extreme accuracy.” USN Photograph 670326 released May 3, 1957.
