Electronic Warfare

Electronic warfare (EW) technology encompasses the systems that use the electromagnetic spectrum to detect, deny, deceive, disrupt, or destroy adversary electronic systems while protecting friendly operations, serving as an increasingly critical capability in modern military conflicts where electromagnetic superiority often determines tactical and strategic outcomes. The electronic warfare market reached $20.4-22.2 billion in 2025 growing at 4.7-6.2% CAGR to $26.5-30.2 billion by 2030. The counter-drone electronic warfare segment reached $4.1 billion growing at 21.3% CAGR to $24.0 billion by 2034. The signals intelligence (SIGINT) market reached $17.6 billion growing at 5.1% CAGR to $29.4 billion by 2035. North America commands 42% of the global EW market.

The Ukraine-Russia conflict has validated electronic warfare as the defining technology of modern combat. Russia deploys 60+ GPS jamming stations along its borders creating persistent denial environments. Both sides use EW to defeat each other's drones, with Ukraine countering Russian jamming through rapidly reprogrammed frequency-hopping systems. The conflict demonstrated that EW capability must evolve at software speed rather than hardware procurement cycles. AI-driven EW systems now classify 32+ simultaneous emitters and react 1,000x faster than legacy systems.

Lockheed Martin, Raytheon (RTX), Northrop Grumman, and L3Harris dominate the EW prime contractor market. Lockheed provides the AN/ALQ-99 replacement (Next Generation Jammer on EA-18G Growler). Raytheon's portfolio includes advanced radar and electronic attack systems. Northrop Grumman builds EW suites for stealth platforms (B-21, F-35 DAS). L3Harris provides tactical EW and communications intelligence. Anduril's Pulsar counter-drone EW system received an $85 million U.S. Army contract (April 2025) demonstrating startup disruption in the EW market. BAE Systems generated $3.2 billion in EW-related revenue across its Electronic Systems segment.

The U.S. Army and Marine Corps are pursuing Modular Open RF Architecture (MORA) to enable rapid capability upgrades without replacing entire EW systems. The concept separates EW hardware from software, allowing new threat responses to be developed and deployed in weeks rather than years. AI-driven cognitive EW represents the most transformative technology trend: systems that autonomously sense the electromagnetic environment, identify threats, develop countermeasures, and adapt responses in real time without human programming for each specific threat.

For founders, electronic warfare in 2026 rewards companies that serve the software-defined EW transition and counter-drone explosion. The most fundable approaches serve software-defined EW systems enabling rapid reprogramming against evolving threats, counter-drone electronic warfare for the $24 billion market by 2034, AI-powered spectrum sensing and classification processing 32+ simultaneous emitters, electromagnetic spectrum management and deconfliction software, and EW simulation and training environments for force readiness.
