Designed for installation on destroyers and larger ships to search for low-flying warplanes and surface ships, it achieved greatly improved surface coverage and detection of aircraft compared with previous lower frequency radars. It also proved a superior navigation aid, making possible the detection of buoys and shoreline at night or bad weather.
