The conflicts in Ukraine since 2022 and in Nagorno-Karabakh in 2020 demonstrated how relatively inexpensive drones, anti-tank guided missiles, and electronic warfare assets can degrade legacy main battle tank fleets, accelerating modernization programmes worldwide. Active protection systems, modular armour, and AI-enabled targeting are now central procurement priorities for NATO members, Russia, China, and an expanding tier of middle-power producers including Turkey, South Korea, and Israel. The core industrial dispute concerns supply chain sovereignty: dependence on foreign optics, engines, and microelectronics has prompted indigenization drives, particularly in Turkey (Altay MBT), India, and several Gulf states. At the same time, export competition has intensified, with South Korean K2 tanks and K9 howitzers, Turkish armoured vehicles, and German Leopard variants competing for European rearmament contracts triggered by the war in Ukraine. Today, debates centre on how to integrate autonomy into ground forces while preserving meaningful human control, how to sustain ammunition production at wartime rates, and how export controls under the Wassenaar Arrangement should evolve as ground systems become increasingly software-defined.

China's rapid fleet expansion, including its third aircraft carrier Fujian and a growing destroyer force, has prompted counter-investments by the United States, Japan, Australia, and India, with the AUKUS pact (2021) marking a generational shift through nuclear-powered submarine transfers. Simultaneously, Houthi strikes on Red Sea shipping since late 2023 have exposed the vulnerability of commercial sea lanes to anti-ship missiles and uncrewed surface vessels. Technological emphasis has shifted toward unmanned surface and underwater vehicles, integrated air and missile defence at sea, hypersonic anti-ship weapons, and quieter conventional submarines with air-independent propulsion. Turkey's MILGEM corvette programme and TCG Anadolu light carrier illustrate how middle powers are pursuing indigenous shipbuilding, while South Korea and Japan have emerged as competitive frigate and destroyer exporters. The contemporary debate spans freedom of navigation in the South China Sea, the legal status of unmanned naval systems under UNCLOS, and how alliances will share submarine and missile defence technologies without triggering proliferation concerns.

The U.S. F-35 has become the backbone of allied air forces, while parallel European efforts — the Franco-German-Spanish FCAS and the UK-Italy-Japan GCAP — aim to deliver next-generation platforms by the late 2030s. Turkey's KAAN fighter, unveiled in 2023, and its TB2 and Akıncı UAV families have positioned it as a notable aerospace exporter, particularly after combat performance in Ukraine, Libya, and Nagorno-Karabakh. In space, the proliferation of ASAT capabilities — demonstrated by Chinese (2007), Indian (2019), and Russian (2021) tests — has raised serious debris and escalation concerns, while stalled negotiations on the Prevention of an Arms Race in Outer Space (PAROS) leave the 1967 Outer Space Treaty as the principal but increasingly strained legal framework. Commercial constellations such as Starlink have also blurred the line between civilian and military space assets, as seen in their battlefield use in Ukraine. Key contemporary questions concern export controls on advanced UAVs under the MTCR, the militarization of low Earth orbit, and how middle powers can secure independent launch and satellite manufacturing capacity.

Mass migration pressures along the EU's external borders, the Türkiye-Syria frontier, and the U.S.-Mexico border have driven investment in surveillance towers, biometric systems, and integrated command centres. Counter-terrorism efforts continue against ISIS remnants in Syria and Iraq, al-Shabaab in the Horn of Africa, and Sahelian jihadist networks, even as great-power competition has reduced multilateral cooperation in some theatres. Cyber threats have escalated sharply: ransomware against critical infrastructure (Colonial Pipeline, 2021), state-linked intrusions disclosed through the SolarWinds and Microsoft Exchange incidents, and cyber operations accompanying the war in Ukraine have pushed cybersecurity from a technical concern to a core national security domain. The UN Open-Ended Working Group on ICT has produced consensus reports on responsible state behaviour, but enforcement and attribution remain contested. Crisis management has gained new urgency after the COVID-19 pandemic, the 2023 Türkiye-Syria earthquakes, and recurring climate-driven disasters, prompting demand for integrated civil-military emergency systems. Current debates focus on balancing security and privacy in border technologies, harmonizing cyber norms, and ensuring interoperability among first responders across borders.

Western states have struggled to sustain artillery ammunition deliveries, prompting multi-year industrial expansion plans by the United States, the EU's Act in Support of Ammunition Production (ASAP, 2023), and South Korea's emergence as a backfill supplier. Stockpile depletion, single-source dependencies for critical materials, and lengthy lead times for missiles and propellants have driven a re-evaluation of just-in-time defence procurement models. Strategic mobility — the ability to move forces and matériel rapidly across theatres — has also been tested, from NATO reinforcement of its eastern flank to coalition resupply during Red Sea operations. Investments in roll-on/roll-off shipping, strategic airlift (C-17, A400M), and prepositioned stocks have accelerated, alongside efforts to harden logistics networks against cyber and kinetic attack. Contemporary debates focus on dual-use commercial logistics, host-nation support arrangements, the role of AI in predictive maintenance and supply forecasting, and how export controls interact with allied logistics burden-sharing under arrangements such as NATO's Defence Production Action Plan.

China dominates global processing of rare earth elements and several critical minerals essential for magnets, optics, and propulsion, prompting the United States, EU, Japan, and Australia to pursue alternative supply arrangements through the Minerals Security Partnership (2022) and the EU Critical Raw Materials Act (2024). Semiconductor restrictions, particularly U.S. export controls on advanced chips to China since October 2022, have further fragmented the technology base. At the equipment level, individual soldier systems, electro-optics, body armour ceramics, and additive-manufactured spares have become areas of intense innovation, with 3D printing increasingly used for forward-deployed maintenance. Standardization remains a persistent challenge: NATO STANAGs aim to ensure interoperability, but national procurement preferences and offset requirements often fragment markets. The contemporary agenda concerns securing access to critical minerals, building resilient and traceable supply chains, applying additive manufacturing at scale, and reconciling national industrial policies with allied interoperability requirements.
