L3Harris Technologies was formed in 2019 through the merger of L3 Technologies and Harris Corporation, creating a $20 billion revenue defense electronics and intelligence firm occupying a critical position in the US military's sensor, communications, and electronic warfare architecture. Though less prominent than the mega-primes, L3Harris is embedded in nearly every major US military platform as a systems integrator for intelligence, surveillance, reconnaissance, and electronic warfare capabilities.
The company's strategic value lies in the intelligence layers of modern warfare rather than the kinetic end. L3Harris builds the sensors that feed AI targeting systems, the radios that carry AI-processed data between units, and the electronic warfare systems that degrade adversary AI-dependent platforms. In an era of AI-enabled warfare, control of the sensing and communications layer is a decisive advantage.
The WESCAM MX-series electro-optical and infrared sensor turrets, found on dozens of aircraft types worldwide, use AI-driven image stabilization and target tracking algorithms. The IVER series of autonomous underwater vehicles deploys AI navigation and payload management for mine countermeasures, hydrographic survey, and covert maritime operations.
L3Harris's electronic warfare portfolio spans airborne, shipborne, and ground-based jamming, deception, and cyber-electromagnetic attack systems that increasingly use AI to adapt waveforms and deception techniques in real time against adversary radar and communications networks.
L3Harris trades on NYSE under LHX with a market cap around $45 billion. The company is a beneficiary of both US DoD AI investment and allied nation spending on ISR and electronic warfare modernization. Revenue growth is driven by increasing demand for AI-enabled sensing and EW systems as militaries adapt to AI-contested battlespace. L3Harris's role as an enabler of larger platform programs (F-35, Army ITN, Navy surface ships) provides sticky recurring revenue for sustainment and upgrade cycles. The company carries some integration risk from the L3/Harris merger. Pays a consistent dividend. Comparable peers: Northrop Grumman (NOC), Elbit Systems (ESLT), Leonardo DRS.
