Overview
L3 Technologies was an American defense, aerospace, and technology company that operated under the L-3 Communications name from its formation in 1997 until a corporate rebranding at the end of 2016. The company was created to acquire selected business units that Lockheed Martin had inherited from Loral Corporation and its predecessor businesses. Its founders, Frank Lanza and Robert LaPenta, had held senior positions at Loral and Lockheed-related organizations, while Lehman Brothers provided financial backing for the initial formation. The name L-3 referred to Lanza, LaPenta, and Lehman Brothers rather than to the separate telecommunications company Level 3 Communications. From a relatively focused acquisition platform, L3 expanded into a broad supplier of systems and services for the United States Department of Defense, Department of Homeland Security, United States intelligence agencies, NASA, aerospace prime contractors, airlines, airports, commercial telecommunications companies, and other government and industrial customers. Its portfolio covered command, control, communications, computers, intelligence, surveillance, and reconnaissance systems; tactical and broadband communications; electronic warfare and signals intelligence; electro-optical and infrared sensors; space and power systems; aircraft components and modifications; maritime sensors and controls; training devices and flight simulators; airport screening equipment; navigation and instrumentation; and specialized propulsion and power technologies. The company grew principally through acquisitions. Among the businesses added during its expansion were Paramax Systems, Link Simulation and Training, Wescam, Titan Corporation, Insight Technology, CTC Aviation, Aerosim, ASV Global, Ocean-Server Technology, and several aviation, maritime, security, sensor, and electronic-systems businesses. These transactions gave L3 a diversified structure spanning both equipment manufacturing and long-term engineering, training, maintenance, and support services. By 2017, its activities were organized around broad groupings that included electronic systems, aerospace systems, communication systems, sensor systems, aviation products and security, power and propulsion, and precision engagement and training. L3 also developed and supplied products for military and civilian applications. Examples included EOTech holographic weapon sights, Wescam stabilized imaging systems, airport passenger and baggage screening equipment, flight and aviation training simulators, secure communications devices, infrared detectors, maritime autonomy products, and reconnaissance and surveillance platforms. Its customers and end users included military personnel, law-enforcement agencies, airport operators, commercial airlines, ship operators, and government research organizations. In December 2016, the company changed its legal and operating name from L-3 Communications Holdings to L3 Technologies, reflecting its expansion beyond traditional communications activities. The company retained the New York Stock Exchange ticker LLL. In October 2018, L3 announced an all-stock merger of equals with Harris Corporation. After receiving the necessary approvals, the transaction closed on June 29, 2019, creating L3Harris Technologies. L3 Technologies therefore ceased to exist as an independent publicly traded company, while many of its businesses and product lines continued within the combined L3Harris organization.
History
L3 Technologies originated in the consolidation wave that followed the merger of Lockheed Corporation and Martin Marietta in 1993. Several businesses that had become part of Lockheed Martin through earlier transactions, including units associated with Loral Corporation, were later selected for acquisition by Frank Lanza and Robert LaPenta. With Lehman Brothers as a financial partner, they formed L-3 Communications in 1997. The initial business model was acquisition-led: assemble complementary defense electronics, communications, aviation, and systems-integration capabilities and serve large government and aerospace customers. The company expanded rapidly during the 2000s. It acquired Paramax Systems, a training and simulation division descended from Hughes and the Link Trainer business, and later added electronic-fuzing, electron-device, aircraft-integration, infrared, security-detection, maritime, and intelligence businesses. The acquisition of Wescam strengthened stabilized electro-optical and infrared imaging. Purchases such as Titan Corporation broadened L3's government-services and national-security presence, while businesses including Insight Technology, Sonoma Design Group, and Applied Signal & Image Technology expanded its sensor, optics, and geolocation capabilities. L3 continued adding specialist businesses in the United Kingdom, Australia, and the United States. These included information-systems and secure-communications specialists, aircraft-structure and modification businesses, acoustic-range and hydrographic operations, and electronic-warfare companies. Its aviation portfolio grew through the acquisition of commercial simulation and pilot-training activities, including parts of Thales Training & Simulation, CTC Aviation, and Aerosim. In parallel, L3 entered or expanded in automated checkpoint security, autonomous surface vehicles, underwater robotics, and advanced battery technologies. By the middle of the 2010s, L3 was no longer principally a communications supplier. Its business covered military and civil aviation, ISR, electronic warfare, sensors, space systems, maritime systems, training, airport security, propulsion, and specialized engineering services. The 2016 renaming to L3 Technologies formally recognized that transformation. In 2017, the company described its activities through business groupings such as Electronic Systems, Aerospace Systems, Communication Systems, Sensor Systems, Aviation Products and Security, Power and Propulsion, and Precision Engagement and Training. Leadership changed during this period. Following Frank Lanza's death in 2006, Michael T. Strianese became interim chief executive and subsequently assumed the chairman, president, and CEO roles. Christopher E. Kubasik joined the senior leadership team as president and chief operating officer in 2015. Strianese announced his retirement as CEO effective at the end of 2017, after which Kubasik became president and chief executive while Strianese remained chairman. L3 also faced compliance and product-quality controversies. In 2010, the United States Air Force temporarily suspended a special-support division from federal contracting following allegations involving the collection of sensitive government-network information. The company was also criticized over counterfeit components and later confronted litigation involving alleged performance defects in EOTech holographic sights supplied to military and other customers. These matters formed part of the regulatory and reputational background against which L3 continued to operate. In October 2018, L3 and Harris Corporation announced an all-stock merger. The transaction closed on June 29, 2019, creating L3Harris Technologies. L3 Technologies consequently became a historical corporate brand and legal entity, although its operations, products, personnel, and capabilities were absorbed into the successor company.
