Electronic warfare, cyber and naval: the electromagnetic and digital contest for maritime control

What it is

Electronic warfare (EW), offensive cyber, and naval power are tracked as a single beat because all three contest the electromagnetic and digital infrastructure modern navies depend on. EW means the deliberate use of the radio-frequency spectrum to attack, degrade, or deny an adversary's sensors, communications, and weapons guidance while protecting one's own. Cyber operations extend that logic into networked systems: combat management software, satellite ground segments, port logistics. Naval forces are acutely exposed because they rely on satellite navigation, encrypted data-links, and, increasingly, remotely piloted unmanned surface vessels (USVs) whose control links are a direct EW and cyber target. The beat tracks state EW programmes, military cyber commands, naval drone development, and the arms-race dynamics that link all three.

History

Modern EW traces to World War II radar countermeasures and the jamming campaigns of the Korean and Vietnam wars. The 1991 US-led Gulf War made EW a mainstream capability: EA-6B Prowlers and EF-111 Ravens suppressed Iraqi radar ahead of strike packages, and AGM-88 HARM anti-radiation missiles hunted emitters. Cyber entered the strategic lexicon after distributed denial-of-service attacks hit Estonian government and banking systems in 2007, the first widely attributed state-linked cyber event. Russia's 2008 war with Georgia added coordinated kinetic-and-cyber action. Stuxnet, disclosed in 2010, proved that software could destroy physical industrial equipment. GPS spoofing became routine in Black Sea shipping lanes and near NATO's Baltic borders from around 2014. Russia's full-scale Ukraine invasion in February 2022 normalized EW and cyber as continuous warfighting tools rather than exceptional ones, and drove a generation of low-cost field-expedient systems that now inform NATO procurement.

Current state

Three threads define the beat as of mid-2026. The drone-versus-jammer race in Ukraine: the Lima and Pokrova EW systems have spoofed or jammed more than 20,000 Russian Shahed drones at roughly €58,000 per unit, but fiber-optic FPVs, which carry no exploitable radio link, now account for 30 to 50 percent of Ukrainian front-line strikes and bypass the EW advantage entirely. Naval drone control-link security is unresolved: the Constanta incident of 5 June 2026 showed that Russia can seize control of Ukrainian USVs and redirect them, an open vulnerability for every Western unmanned surface vessel programme. And North Korea's Choe Hyon destroyer, commissioned June 2026 at Nampho Shipyard, adds a nuclear-capable 5,000-tonne surface combatant to Northeast Asia's naval balance, complicating US carrier-group deployments in the western Pacific.

Relationships

EW and cyber intersect at the link layer: intrusion into a ship's combat management system is an electronic attack by another route. GNSS spoofing affects both military and civilian maritime navigation, as cargo ships in the Eastern Mediterranean discovered when false coordinates placed them inland on charts, disrupting commercial traffic unrelated to any conflict. Naval drone programmes must harden control links against EW hijacking while keeping platforms affordable. Russia's Krasukha-4 and Murmansk-BN systems demonstrate long-range jamming capable of suppressing NATO HF communications across broad geographic bands. China's People's Liberation Army runs large-scale electromagnetic suppression exercises in Pacific waters, combining EW, cyber, and naval operations in the same configuration that Russia has field-tested over the Black Sea. States that lead in one domain invest to suppress the adversary's equivalent, making EW programme visibility, cyber command capability, and naval drone fleet size the three indicators that analysts track together.

What to watch

• Whether Ukraine deploys fiber-optic-guided naval drones that bypass Russian EW and how Russia adapts, through net-capture, kinetic interception, or optical-guidance jamming.
• NATO's post-Ukraine EW procurement and doctrine, including allied adoption of Lima-class systems for the eastern flank and the High North, driven by lessons from Pokrova and Bukovel-AD.
• China's EW and cyber posture in the Taiwan Strait, specifically jamming reach and network operations against Taiwan's command-and-control infrastructure.
• GNSS spoofing accountability: the International Maritime Organization and ICAO are under pressure to establish binding attribution and liability rules after civilian maritime disruption spread from the Black Sea to the Red Sea and Eastern Mediterranean.
• North Korea's Choe Hyon follow-on vessels and whether the DPRK navy integrates EW as a fleet-wide capability rather than a point defence for a single prestige platform.
