About Data Device Corporation

You'd be forgiven if you thought that ILC Industries stood for I Love Companies. ILC is a holding company for a group of businesses. Its mainstay subsidiary, Data Device Corp. (DDC), makes and sells microelectronic components used in data conversion and networking products (cards, software, and fiber channel switches) by the defense, space, and aerospace industries. Its oldest subsidiary, ILC Dover, was spun-off in 2011, cutting ILC's ties to engineering and making softgoods for industrial, military, and space applications (blimps, spacesuits, and chemical-biological warfare protection gear). ILC customers have included Boeing, Lockheed Martin, and NASA. Buyout firm Behrman Capital owns a majority stake in ILC.
