The SC-2 was the chief destroyer radar of the war, and models remained in use until 1963.  It used the same set as an SK but a smaller antenna (15' by 4'6" or 4.6m by 1.4m, composed of 6x2 dipoles) that sacrificed altitude resolution and power in return for a lighter weight. Like the SK, it had a PPI display, integral IFF, and (in later marks) antijamming features.
