AN/TPS-43

In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/TPS-43" designation represents the 43rd design of an Army-Navy electronic device for ground transportable search radar system. The JETDS system also now is used to name all Department of Defense electronic systems. The AN/TPS-43 is a ground-based, non-fixed (i.e.: transportable) search radar. The entire system can be broken down and packed into two M35 trucks for road transport. An updated version replacing the original shaped reflector and organ-pipe scanner with a phased array antenna was originally known as the TPS-43E2, but emerged as a much more modern system and was renamed the AN/TPS-75. TPS-75 is the current transportable air control and warning (AC&W) radar used by the United States Air Force. == Variants ==

In addition to the basic TPS-43 several variants were developed. • 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 (4 megawatt export version designed for Pakistan) • 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. 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. Another set installed at Rio Grande, in the mainland, was used to guide Argentine attacks on the British fleet. == Users ==
