Topics & background

The background behind each topic and the actors that shape it.

Command, Control & Communications (C3) in Modern Defence

Command, Control and Communications (C3) systems form the nervous system of modern military operations, enabling commanders to direct forces, share intelligence, and coordinate across domains. The discipline evolved from Cold War-era hardened radio and satellite networks into today's networked, software-defined environment, where interoperability across allied forces and resilience against jamming, cyber intrusion, and kinetic attack are paramount. Japan's 2022 National Security Strategy and the establishment of a Joint Operations Command (scheduled to stand up in 2025) reflect a regional push toward integrated, cross-domain C3 architectures. The core contemporary debate centres on multi-domain integration — linking land, sea, air, space, and cyber assets — and on the standards governing allied interoperability. NATO's Federated Mission Networking and the US Joint All-Domain Command and Control (JADC2) concept are reshaping procurement expectations among partners. In the Indo-Pacific, Japan, the United States, Australia and the United Kingdom are working through frameworks such as AUKUS Pillar II and the US-Japan alliance modernization to align C3 standards, while concerns over Chinese and Russian electronic warfare capabilities drive investment in resilient, low-probability-of-intercept communications. Today, the field is defined by the tension between rapid commercial innovation (LEO satcom, 5G, AI-enabled decision support) and the security requirements of sovereign defence networks. Export controls, supply-chain assurance, and the integration of AI into command workflows are unresolved policy questions with direct implications for alliance cohesion.

Key players

Counter-Unmanned Aerial Systems (Counter-UAS)

The proliferation of small, low-cost unmanned aerial systems has transformed the threat landscape over the past decade. Conflicts in Nagorno-Karabakh (2020), Ukraine (since 2022), the Red Sea, and Israel-Gaza have demonstrated that commercially derived drones and loitering munitions can degrade armoured formations, strike critical infrastructure, and saturate traditional air defences at a fraction of the cost of intercepting them. Counter-UAS (C-UAS) has accordingly moved from a niche force-protection concern to a top-tier capability requirement. C-UAS encompasses detection (radar, RF, acoustic, EO/IR), identification, and defeat mechanisms ranging from electronic attack and GNSS spoofing to kinetic interceptors, directed-energy weapons, and high-power microwaves. Japan, exposed to incursions near its southwestern islands and concerned about North Korean and Chinese UAS activity, has prioritized C-UAS in successive defence buildups. The United States, United Kingdom, Israel and others have fielded layered systems, but cost-exchange ratios, airspace deconfliction, and rules of engagement in civilian areas remain difficult problems. The current policy debate centres on standardization across allies, export controls on dual-use counter-drone technology, and the legal framework for engaging UAS over civilian or contested airspace. Directed-energy systems are maturing but face power, cooling, and weather constraints, while AI-enabled swarm threats are accelerating faster than defensive doctrine.

Key players

Defence Electronics & Subsystems

Electronics and subsystems underpin virtually every modern defence platform — from radar and electronic warfare suites to mission computers, displays, and power management modules. The sector has been reshaped by the convergence of commercial semiconductor innovation and military requirements for radiation hardening, ruggedization, and trusted supply chains. Recent shocks, including the COVID-era chip shortage and escalating US-China technology competition, have made semiconductor sovereignty a defence-industrial priority for Japan and its partners. Japan's defence electronics base — anchored by firms such as Mitsubishi Electric, NEC, and Toshiba — has historically supplied highly capable subsystems but operated under tight export restrictions. The 2014 revision of arms export principles and subsequent loosening have opened cooperation, exemplified by the UK-Italy-Japan Global Combat Air Programme (GCAP), which depends on shared electronics development. Allied governments are also tightening controls on advanced node semiconductors and trusted foundry access under frameworks coordinated with the United States and the Netherlands. The contemporary policy questions involve securing supply chains against single points of failure (notably Taiwanese fabs), accelerating qualification of commercial-off-the-shelf components for military use, and managing dual-use export controls without strangling allied co-development.

Key players

Advanced Materials & Defence Manufacturing

Advanced materials — composites, ceramics, high-temperature alloys, additive-manufacturing feedstocks, and stealth coatings — increasingly determine the performance envelope of defence platforms. From the carbon-fibre structures of next-generation fighters to the ceramic matrix composites in hypersonic vehicles and the rare-earth magnets in precision actuators, materials science is now a strategic domain. Japan holds globally significant positions in carbon fibre (Toray), specialty steels, and precision machining. Manufacturing methods are simultaneously being transformed by additive manufacturing, digital twins, and AI-driven process control, allowing faster prototyping, distributed production, and resilient logistics. The war in Ukraine has highlighted the strategic value of munitions production scale, prompting Japan, the United States and European partners to invest in expanded production lines for missiles, artillery shells, and propellants. Rare-earth dependence on China — which dominates processing — remains a persistent vulnerability driving allied diversification efforts with Australia and others. Key policy debates include onshoring and "friend-shoring" of critical materials, qualification standards for additively manufactured defence parts, intellectual property protection in co-development programmes such as GCAP, and the environmental footprint of energetic materials and composites.

Key players

Mission Sensors & Payloads

Mission sensors and payloads — including radar, electro-optical/infrared (EO/IR) systems, signals intelligence packages, sonar, and synthetic aperture radar — define the situational awareness available to commanders. Over the last two decades, the proliferation of small satellites, unmanned platforms, and AI-enabled processing has democratized access to high-resolution, persistent sensing. Commercial space imagery from providers such as Maxar, Planet, and Japan's iQPS and Synspective has reshaped intelligence collection, as demonstrated in Ukraine and the South China Sea. Japan is investing heavily in maritime domain awareness around the Senkaku Islands and Taiwan Strait, expanding its constellation of imaging and signals satellites and upgrading airborne and shipborne sensors. The US-Japan alliance integrates sensor data through shared architectures, and trilateral cooperation with Australia and South Korea is deepening. At the same time, adversary investments in stealth, electronic warfare, and decoys are eroding traditional sensor advantages, pushing development toward multi-spectral fusion and AI-enabled target recognition. Current debates include the appropriate balance between exquisite, sovereign sensors and resilient commercial constellations; export controls on high-resolution imaging and SIGINT payloads; and the legal and ethical questions raised by AI-driven automated target recognition.

Key players

Positioning, Navigation & Guidance (PNT)

Reliable positioning, navigation and timing underpins precision strike, logistics, communications, and virtually all networked operations. GPS, GLONASS, Galileo, BeiDou and Japan's Quasi-Zenith Satellite System (QZSS) provide global and regional services, but military operations are increasingly contested by jamming and spoofing — vividly demonstrated in Ukraine, the eastern Mediterranean, and the Korean peninsula. The vulnerability of GNSS has elevated alternative PNT — inertial navigation, celestial, vision-aided, terrain-referenced, and quantum sensing — to a strategic priority. Japan's QZSS provides a regional augmentation and backup that enhances accuracy and resilience for both civilian and defence users, and is being expanded toward a seven-satellite constellation. Allied work on M-code GPS receivers, Galileo PRS access, and assured-PNT chipsets is accelerating. Precision guidance for munitions — combining GNSS, inertial measurement units, and increasingly AI-aided terminal seekers — is a focal point of munitions modernization across NATO and Indo-Pacific allies. Policy challenges include interoperability across allied PNT systems, export controls on high-grade IMUs and guidance kits, protection of civilian GNSS from spillover jamming, and the strategic implications of China's BeiDou as both a competitor and a tool of influence.

Key players

Professional Services in the Defence Sector

Professional services — including consulting, systems engineering, legal and regulatory advisory, training and simulation, cybersecurity assurance, and through-life support — have become an indispensable layer of the defence enterprise. As platforms grow more software-intensive and procurement programmes more complex (GCAP, AUKUS, Future Combat Air Systems), governments increasingly rely on external expertise to manage acquisition, integration, and sustainment. Japan's defence buildup, accompanied by a roughly doubled defence budget by 2027, has expanded demand for industrial partnering, export-control compliance, and acquisition reform. The sector also encompasses workforce development, language and cultural training for coalition operations, and specialized legal services covering international humanitarian law, arms export regulation, and cyber norms. Japan's recent revisions to its Three Principles on the Transfer of Defense Equipment and Technology have opened new export pathways and created demand for compliance and partnering expertise. Globally, lessons from Ukraine have underscored the value of contracted logistics, training pipelines, and rapid acquisition support. Policy questions include the appropriate boundary between inherently governmental functions and contracted services, oversight of private military and security companies, conflict-of-interest management in advisory roles, and the security clearance and supply-chain assurance frameworks needed for cross-border professional services.

Key players

Propulsion & Power for Defence Platforms

Propulsion and power systems are foundational to every defence platform, from jet engines and naval gas turbines to electric drives, batteries, and emerging hypersonic propulsion. The shift toward more-electric and all-electric platforms — driven by directed-energy weapons, high-power sensors, and AI-enabled subsystems — is reshaping requirements for onboard power generation, distribution, and thermal management. Submarines, surface combatants, and next-generation aircraft increasingly demand step-changes in available electrical power. Japan has a mature engine and turbine industry (IHI, Kawasaki, Mitsubishi Heavy Industries) and is a partner in GCAP's next-generation engine development alongside Rolls-Royce and Avio Aero. Hypersonic and scramjet propulsion are active research areas in the United States, China, Russia, and increasingly Japan and European partners. Meanwhile, naval nuclear propulsion is at the heart of AUKUS, with significant non-proliferation and industrial-base implications. Battery technology — particularly for unmanned underwater and aerial systems — is another contested frontier with strong civil-military overlap. Key policy debates include export controls on advanced engine technology, decarbonization pressures on defence fleets, sovereignty over critical propulsion supply chains (including rare earths for electric motors), and the safety and proliferation implications of expanding naval nuclear propulsion to new operators.
