AN/TPS-43

The AN/TPS-43 is a transportable 3-dimensional air search radar produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman. It completed development in 1963 and entered US service in 1968. The entire system can be broken down and packed into two M35 trucks for road transport. The TPS-43E2 was redesignated the AN/TPS-75 which is the current transportable air control and warning (AC&W) radar used by the United States Air Force.

This radar was deployed by the Argentine Air Force during the 1982 Falklands War to Stanley and survived two British attacks with AGM-45 Shrike anti radar missiles on May 31 and June 3. One of the radars was captured by British forces after the Argentine surrender and deployed at RAF Buchan
