International Signal and Control
International Signal and Control (ISC) was a U.S. defense contractor based in Lancaster, Pennsylvania, that was involved in the manufacture of electronic missile subassemblies, navigation components, fuses, power supplies for proximity fuzes, and grenade technology.
By the 1980s, ISC's business primarily consisted of illegal arms sales started at the behest of various US clandestine organizations. On paper the company looked to be extremely profitable on sales of high-priced legitimate items, but in fact these profits were essentially non-existent. After the sale of the company to Ferranti in 1987, all illegal sales ended immediately, leaving the company with no obvious cash flow, and the merger led to the ultimate collapse of Ferranti in 1991.
ISC was involved in two major crimes, for which CEO James Guerin received a 15-year prison sentence:
- It defrauded and caused the collapse of the British company Ferranti, which acquired it in 1987.
- It exported classified military technology to South Africa, which was then forwarded to third countries, notably Iraq.
