India's defense startups are shifting focus from aerial drones to underwater technologies as the Indian Navy accelerates procurement of autonomous systems. While the sector sees new contracts like EyeROV's ₹47-crore deal, investors are also witnessing volatility in stocks like C2C Advanced Systems amid audit concerns and regulatory fines.
The Indian defense-technology landscape is undergoing a significant transition as startups pivot their focus from the saturated aerial drone market to underwater domains. Driven by the Indian Navy's push to integrate indigenous technologies into its fleet, this shift is moving local firms from the prototype phase—often supported by government incubators like iDEX—to full-scale operational procurement.
Transitioning from Prototypes to Orders
For years, many defense startups primarily focused on research and pilot projects. The current environment is changing as the Navy begins placing actual procurement orders for autonomous vessels, mine-countermeasure systems, and advanced surveillance gear. A notable example is EyeROV, which secured a ₹47-crore contract from the Indian Navy for its Trout underwater drone systems. These units are being deployed for inspection and surveillance tasks, marking a key milestone in moving indigenous prototypes into active military service.
Beyond hardware, companies like Ammunic Systems are working on underwater fuzing technology, aiming to replace imported components. Additionally, firms such as Yaanendriya are exploring dual-use applications for their navigation and sensing technologies. By targeting both defense contracts and civilian uses, such as supporting the maritime navigation needs of coastal fishermen, these companies are attempting to build more sustainable revenue models that go beyond one-off defense orders.
Market Realities and Investor Risks
While the sector shows promise, the path to building a profitable, scalable defense business remains complex. The transition from designing a working prototype to managing large-scale manufacturing involves significant execution risk and capital requirements. Investors tracking this sector are currently seeing a divergence in performance, particularly among publicly listed firms.
For instance, C2C Advanced Systems, which provides C4ISR platforms and counter-drone systems, has faced a challenging period. As of October 1, 2026, the company’s share price stood at ₹185.90, reflecting an 11.18% decline. This market movement follows recent company disclosures regarding regulatory issues, including the payment of a ₹2.95 lakh fine to the National Stock Exchange. Additionally, the company has dealt with audit-flagged concerns regarding financial statements and liquidity. These developments highlight the risks associated with investing in smaller defense-tech firms, where operational stability, financial reporting transparency, and regulatory compliance are essential for long-term growth.
Tracking the Next Phase
Moving forward, the primary monitorable for this sector will be how effectively these companies scale their operations to meet delivery timelines without compromising on quality or incurring cost overruns. For startups, achieving the required indigenous content levels while maintaining a stable cash flow will be critical. Investors will likely look for updates on contract execution progress, the ability of these firms to manage their debt levels, and the outcome of ongoing efforts to resolve regulatory and audit-related challenges in specific company cases.
