Global Defense Giants Pour Billions into Drone and AI Startups Amid Shifting Battlefield Needs

The world's largest defense companies are aggressively investing in startups specializing in drones, maritime robots, sensors, artificial intelligence, and autonomous combat systems, reflecting rapid battlefield changes. In 2026, major defense firms like Lockheed Martin and BAE Systems participated in venture capital funding rounds totaling $4.1 billion, according to the Financial Times. This figure represents the largest annual investment recorded by Dealroom for primary defense contractors' involvement in military startup funding.

This influx of capital signifies a strategic pivot for traditional arms manufacturers, who for decades relied on fighter jets, warships, armored vehicles, and large weapon systems. They are now racing to gain access to technologies that can be developed, tested, and produced more rapidly. Conflicts in Ukraine and other recent engagements have demonstrated the significant role that inexpensive drones, interceptor missiles, software, sensors, and unmanned vehicles can play, often without the need for multi-billion dollar platforms.

"Recent conflicts highlight the need for modern warfare, where established legacy platforms coexist with new disruptive technologies," said Gwen Billon, a partner at investment bank PJT, who leads the firm's aerospace and defense business. Billon noted that new defense technologies will persist beyond conflict resolution, making it crucial for major defense companies to secure access and exposure to them.

Overall transactions in the global defense industry, including mergers, acquisitions, and fundraising, have surpassed $40 billion (approximately Rp723.5 trillion) in 2026. This trajectory is set to exceed the previous annual record of $59 billion set in 2019. Dealroom data also shows defense and security sector startups have raised around $39.8 billion (Rp719.9 trillion) this year, indicating capital is flowing not only through acquisitions but also direct funding to burgeoning technology firms.

The shift was evident at the 2026 Farnborough International Airshow in the UK, where defense sector participants constituted the highest proportion in the event's history. Over 650 investors, bankers, and fund managers also attended, underscoring the view of defense technology as a high-growth investment area.
