About
Leidos Holdings, Inc. is a Reston, Virginia-based defense, intelligence, and civil government IT services company — publicly traded on the New York Stock Exchange (NYSE: LDOS) as an S&P 500 Industrials component — providing national security solutions (IT services for US intelligence community, Department of Defense analytics, cybersecurity), health and civil government services (VA electronic health records, HHS IT systems, FAA air traffic control modernization), and commercial services through approximately 47,000 employees. In fiscal year 2024, Leidos reported revenues of $16.7 billion (+8% year-over-year), with the National Security & Digital segment generating the majority of revenue from classified intelligence community IT programs and Department of Defense cybersecurity and analytics contracts, while Health & Civil generated revenue from the Leidos Digital Modernization contract for the Department of Veterans Affairs electronic health records (replacing VistA legacy EHR with Oracle Cerner's Millennium platform) — a 10-year, $10+ billion program that was simultaneously Leidos's largest contract and largest program execution challenge. CEO Tom Bell (joined 2023, previously from Rolls-Royce North America) has focused Leidos on transitioning from IT services to technology-enabled solutions: augmenting traditional government IT labor with proprietary software products (Leidos AI/ML platforms, cloud migration tools, cybersecurity automation) that generate higher margins than staff augmentation. The $1.65 billion acquisition of the security detection and automation business of Smiths Group (X-ray security screening equipment — baggage scanners for TSA checkpoints) in 2021 expanded Leidos into physical security hardware and detection systems for government and commercial airports.
Melbourne FL defense electronics (NYSE: LHX) $21.3B FY2024 revenue (+8%); tactical radios, ISR, electronic warfare, JADC2 networks, Falcon radio family competing with Raytheon and Northrop Grumman.
About
L3Harris Technologies, Inc. is a Melbourne, Florida-based defense electronics and technology company — publicly traded on the New York Stock Exchange (NYSE: LHX) as an S&P 500 Industrials component — providing advanced defense electronics, intelligence, surveillance and reconnaissance (ISR) systems, communication systems, and aviation products for US and allied defense forces through approximately 47,000 employees across four segments: Integrated Mission Systems (ISR aircraft modifications, electro-optical/infrared systems, maritime patrol aircraft), Space & Airborne Systems (military satellite communications, electronic warfare, precision weapons guidance), Communication Systems (tactical radio communications, night vision devices, public safety communications), and Aerojet Rocketdyne (integrated into L3Harris via investment, pending completion). L3Harris Technologies was formed in June 2019 through the merger of L3 Technologies and Harris Corporation — combining Harris's radio communication and space systems expertise with L3's ISR sensors, aircraft modification, and training systems capabilities to create the sixth-largest US defense contractor by revenue. In fiscal year 2024, L3Harris reported revenues of $21.3 billion (+8% year-over-year), with strong growth driven by JADC2 (Joint All-Domain Command and Control) radio and network programs, F-35 avionics subsystems production, and international NATO ally military communication equipment demand. CEO Christopher Kubasik has focused on margin improvement and portfolio optimization — divesting non-core businesses (commercial aviation training — sold Pilot Training business, Link Simulation & Training to CAE) while investing R&D in the electronic warfare (EW) and space domain awareness capabilities where L3Harris holds differentiated technology advantages.
