International Signal and Control

International Signal and Control was a U.S. defence contractor involved in the maufacture of night vision systems, missile and navigation components, fuses, power supplies for proximity fuses, and grenade technology.

ISC was involved in two major indiscretions:

• 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 counties, notably Iraq.

ISC was acquired by Ferranti in 1987, which collapsed in 1993 due to the debts of its new subsidiary. International Signal and Control's CEO James Guerin was found guilty of defrauding Ferranti by inflating the order the book of ISC, prior to and during the acquisition, with fictitious contracts. Ferranti was broken up and the majority of the defence businesses were purchased by GEC.
