The Impact of the Russia-Ukraine Conflict on the Defense Industry
The Russia-Ukraine conflict has been a significant disruptor in the global defense and aerospace industries since it began in February 2022. As of November 2023, the war has continued for 640 days, inflicting severe economic losses on both Russia and Ukraine. Russia has experienced a $350 billion decrease in output as of March 2023, while Ukraine’s economy has shrunk by 30%, losing $500 billion in GDP.
The conflict has had a particularly disruptive effect on the global space industry. The International Space Station (ISS) program remains intact despite earlier threats from Russia to withdraw, but other space collaborations have been severely affected. Western space agencies, including those from the U.S. and Europe, have faced significant delays and the cancellation of Russian launches, leading to a ripple effect throughout the sector.
Moreover, the defense sector has also seen extensive disruptions in logistics, transportation, and supply chains. The conflict has caused a spike in global jet fuel prices, reduced freight capacity in Europe, and complicated the availability of critical resources such as titanium, nickel, neon, and palladium. This has resulted in increased operational costs for defense contractors and other defense-related industries.
Effects on Commercial Aviation
The war has significantly impacted commercial aviation as well. The European Union (EU), United Kingdom (UK), and the United States have all imposed bans on Russian aircraft, forcing airlines to reroute flights and avoid Russian airspace. This has further complicated global logistics, particularly in Europe, where airspace restrictions have added to fuel consumption and operational costs.
The Shift to Hydrogen Fuel
One of the most forward-looking trends emerging from this conflict is the push for renewable energy in defense, particularly the adoption of hydrogen fuel as a key element of energy resilience and security. NATO, for instance, is shifting its focus toward renewable energy, reducing reliance on traditional fossil fuels to enhance operational mobility across aviation, maritime, and terrestrial defense systems.
Countries like Germany, Japan, and the United States are at the forefront of this movement. Germany’s Bundeswehr, for example, is exploring hydrogen-powered vehicles to reduce environmental impact and enhance energy independence. Japan’s Defense Ministry is adopting hydrogen fuel cell technology for unmanned vehicles and mobile power generation. Meanwhile, the United States military is experimenting with hydrogen fuel cells for tactical vehicles, which promises lower emissions and longer operational endurance.
Despite these promising developments, significant challenges remain for the widespread adoption of hydrogen in defense. Infrastructure limitations, high costs, and the need for technological advancements present obstacles that will require coordinated efforts between governments, industries, and research institutions to overcome.

Rising Global Defense Spending
As geopolitical tensions rise, defense spending continues to surge. Global military expenditures grew by 3.7% in 2022, reaching an all-time high of $2.24 trillion. This increase is driven by the ongoing conflicts in Ukraine, Israel-Palestine, and rising tensions with countries like China and North Korea.
The United States remains the largest defense spender, accounting for 39.1% of global military expenditure in 2022. It is followed by China (13%), Russia (3.8%), India (3.6%), and Saudi Arabia (3.3%). Together, these five countries contribute to 63% of total global defense spending.
Despite the economic fallout from the COVID-19 pandemic and inflationary pressures, defense spending has shown remarkable resilience, underscoring the critical importance of military preparedness in the current global landscape. Countries are investing heavily in modernizing their military capabilities, with a focus on emerging technologies like AI, autonomous weapons, and renewable energy.
Increasing Investment in Autonomous Weapons
One of the most transformative trends in the defense industry is the growing investment in autonomous weapons systems, driven by advancements in artificial intelligence (AI). Autonomous weapons, such as drones equipped with AI-powered targeting systems, are changing the way wars are fought.
Examples of Autonomous Weapons
- AI-Enabled Drones: In the ongoing Ukraine conflict, Russia has deployed the KUB-BLA drone, an autonomous munition developed by Kalashnikov and Zala Aero Group. This drone uses AI Visual Identification (AIVI) technology to autonomously recognize and classify targets in real time, allowing for precise strikes without human intervention.
- Israeli Harpy Drone: The Israeli military has used the Harpy drone, an autonomous loitering munition designed to detect and destroy radar emitters with minimal human oversight. Manufactured by Israel Aerospace Industries, the Harpy exemplifies how AI-enabled systems are being integrated into defense strategies worldwide.
- US MQ-9 Reaper: The United States military has deployed autonomous systems such as the MQ-9 Reaper, which played a key role in the 2020 killing of Iranian commander Qasem Soleimani. The drone was operated autonomously, demonstrating the potential for AI-driven weapons to carry out complex missions with reduced human involvement.
The autonomous weapons trend is expected to accelerate in the coming years. AI is now being integrated into broader defense systems, including manned-unmanned teaming, which enables AI-driven drones to collaborate with human pilots. The U.S. Air Force, for example, is developing AI pilots under its Skyborg program and has allocated a budget of $5.8 billion for the procurement of 1,000 autonomous combat aircraft.

Artificial Intelligence and Manned-Unmanned Teaming
In addition to fully autonomous systems, the defense industry is increasingly focused on integrating AI with manned aircraft to create manned-unmanned teams. Shield AI’s Hivemind, an advanced AI pilot system, is a prime example. Hivemind can be deployed across a wide range of aircraft, from F-16 and F-22 fighter jets to the unmanned XQ-58A Valkyrie.
This manned-unmanned teaming approach allows human pilots to command and coordinate swarms of AI-driven drones, significantly enhancing battlefield effectiveness. With AI taking over more routine tasks, human operators can focus on complex decision-making, increasing operational efficiency and safety.
The future of warfare is increasingly intertwined with AI-driven systems, and this trend will continue to shape defense investments in the coming years.
As the defense industry heads into 2024, several critical trends are reshaping the landscape. The ongoing Russia-Ukraine conflict continues to disrupt global supply chains, logistics, and aerospace programs, while simultaneously driving up defense spending worldwide. The shift toward hydrogen fuel and renewable energy is gaining momentum, promising to reduce the environmental impact of military operations and enhance energy resilience.
At the same time, the rise of autonomous weapons and AI-driven systems is revolutionizing warfare, with nations investing heavily in cutting-edge technologies to maintain a competitive edge. As these trends unfold, the defense industry will remain a dynamic and evolving sector, heavily influenced by geopolitical events, technological advancements, and global security priorities.
For defense contractors, governments, and industry stakeholders, staying ahead of these trends will be crucial to navigating the complexities of the modern defense landscape.
