L-3 Technologies and Harris Corp. have agreed to merge in an all-stock deal, the two companies announced in October, creating a $33.5 billion military technology company. The combined company will be called L-3 Harris Technologies and will be based in Melbourne, Fla., the home of Harris Corp. The deal is expected to close next year, pending a review by the U.S. Department of Defense. Harris handles complex military communications networks for battlefield management and military aircraft. It is also known for a brand of Stingray cell phone trackers used by U.S. law enforcement. New York-based L-3 Technologies provides the 360-degree scanners that travelers encounter when they go through airport security, part of a $170 million line of business with the Department of Homeland Security. It also makes night-vision equipment and sensor systems used in military aircraft. The company has established new business units around next-generation military technologies such as undersea drones.
