The U.S. Navy in the late 1960s began working on HARM, or high-speed anti-radiation missile, a weapon designed to home in on and knock out enemy communications installations. TI had built guidance systems for years, but with HARM it designed the whole missile. More than 20,000 have been built, with some being deployed in Libya and the first Gulf War.
The picture shows an anechoic chamber used to test the guidance system in HARM.
