18 Μαΐ 2016 · During World War II, the US Navy deployed two major radar series: search sets (BuShips) and fire control systems (BuOrd). The former carried over a system consisting of a type letter, eg S (search radar), and a model letter: thus SC is the third US search radar; and SC-S is the fifth modification of SC.
SK was an American-made air-search radar used during World War II by the United States Navy. Models included SK-1, SK-2 and SK-3. [2] SK was a very high frequency search set for large ships. It furnished range and bearing of surface vessels and aircraft, and it could be used for control of interception.
SK was an US-American air search radar set using on large ships at the end of World War II. It was essentially an SC-2 radar set with a larger antenna with 6×6 dipoles (15 ft × 16 ft 9 in., ≙ 4,57 × 5,10 m).
Also known as CXFA, the SK was an air search radar developed from the SC-2 with a CXAM antenna. Identification Friend or Foe (IFF) was provided by a Bl-5 antenna atop the main SK antenna.
The high, small antenna on the left tower serves a SG surface search radar and the large antenna on the same tower feeds a SK air search radar. The right tower holds a CXHR prototype three dimensional search radar and a Mark 12,22 fire control radar with height finder.
SC-2 and SC-3 also have PPI scopes, remote PPI's, and built-in antennas. With antennas at 100, SC and SC-1 (without preamplifier) have a reliable maximum range of 30 miles on medium bombers at 1,000 altitude.
It was made up of a modified SC radar using the large CXAM-1 antenna, and it had a built-in PPI display in addition to the A-scope. The SK radar, developed at the Naval Research Lab and built by General Electric Co., would be the Navy’s best long range radar from 1943 to the end of the war.
