The SCR-520 was an air intercept radar
for night fighters. It was used in the P-61 Black Widow but was superceded by SCR-720. The scope could be set
for maximum ranges of 1, 10, or 100 miles (1.6, 16, or 160 km),
which was rather optimistic on the high end. It could search a full
180° forward of the aircraft, and its altitude search settings were -10°
to 45°, 20°, 35°, 50°, or 65°.
A number of sets were converted to SCR-517 surface search radar.
