India has the third-largest startup ecosystem in the world, and in recent years, it has also emerged as a key player in defense innovation.

Over the past 5 – 6 years, the country has witnessed a rapid rise in defense-tech startups, fostering a growing ecosystem dedicated to advanced military solutions.

A significant shift occurred in February 2018 when the Ministry of Defense introduced the draft Defense Production Policy.

This policy set ambitious targets—tripling the defense sector’s turnover to ₹1.75 lakh crore and increasing defense exports nearly 15 times to ₹25,000 crore by 2025.

A crucial aspect of this initiative was encouraging innovation through startups, a move that many initially viewed with skepticism.

Today, as evolving geopolitical challenges demand stronger security solutions, homegrown defense-tech startups are stepping up with groundbreaking advancements.

From AI-powered drones and marine robotics to advanced electro-optics and swarm warfare solutions, these companies are redefining India’s defense capabilities and positioning the country as a key player in global defense technology.

Here are 10 defense tech startups making a significant impact in this space.
