The AN/TPS-43 radar set

The AN/TPS-43 is a transportable air search 3D radar produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman.

Description

The AN/TPS-43 is a ground-based, non-fixed (i.e.: transportable) search radar.[n 1][1]

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.[citation needed]

Variants

In addition to the basic TPS-43 several variants were developed.[2]

  • TPS-43A (antenna tilt; new IFF)
  • TPS-43B (enlarged shelter; changes to transmitter)
  • TPS-43C / 43CX (increased reliability; IFF improvements)
  • TPS-43D / 43DX (ISLS added; maximum detection range increased)
  • TPS-43E (major redesign; improvements to electronics, mechanics and shelter)
  • TPS-43F / subvariants V1 to V6 (major redesign; enlarged shelter, improved electronics; increased reliability)
  • TPS-43G (4MW version designed for Pakistan)[3]
  • TPS-43M (improved electronics; increased dynamic range; improved IFF incorporating several modules in a single unit)
  • TPS-430

Operational history

The AN/TPS-43 completed development in 1963 and entered US service in 1968.[citation needed]

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.[4] One of the radars was captured by British forces after the Argentine surrender and deployed at RAF Buchan[5] Another set installed at Rio Grande, in the mainland, was used to guide Argentine attacks on the British fleet.[6]
