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.
