Apollo Micro Systems Limited announced on 22 July 2026 that it has secured a Make-II Prototype Sanction Order (PSO) from the Indian Navy for the development of SAVIOR-ASW, a semi-submersible autonomous vessel designed for anti-submarine warfare surveillance. The award represents the company's formal entry into the autonomous maritime and underwater warfare systems domain and is positioned as one of the most significant indigenous defence technology milestones in the company's operational history.
Key Highlights
- Apollo Micro Systems received a Make-II Prototype Sanction Order from the Indian Navy for the SAVIOR-ASW autonomous underwater surveillance system on 22 July 2026.
- SAVIOR-ASW is an unmanned, semi-submersible autonomous vessel designed specifically for anti-submarine warfare surveillance and underwater threat detection using hydrophone arrays.
- The Make-II procurement category under India's Defence Acquisition Procedure commits the Government to procure successful prototypes at scale, backed by formal Navy procurement intent.
- The company estimates the overall addressable market for autonomous maritime systems at approximately USD 10 billion by 2032, based on publicly available information.
- According to the announcement, approximately 95% of India's trade by volume moves by sea, with the Indian Ocean Region handling nearly 100,000 merchant vessel transits annually and 42% of global crude oil trade.
- The system is designed to operate silently beneath the sea surface and transmit intelligence continuously to Naval command centres without human presence onboard.
- Apollo Micro Systems has contributed to underwater warfare systems through DRDO programmes and manufactures critical technology components in-house at its IDA Mallapur facility in Hyderabad.

Announcement in Detail
The Prototype Sanction Order (PSO) awarded to Apollo Micro Systems falls under India's Make-II category, one of the Defence Acquisition Procedure's progressive indigenous defence procurement pathways. Under this framework, Indian companies develop fully funded indigenous prototypes of advanced military systems with formal Government commitment to procure successful prototypes at scale. The PSO serves as formal authorisation for prototype development, backed by documented Navy procurement intent. For Apollo Micro Systems, the award signifies the Indian Navy's formal endorsement of the company's capability to design and deliver an autonomous maritime surveillance system developed entirely within India, aligning with Atmanirbhar Bharat objectives in advanced defence technology.
SAVIOR-ASW, or Semi-Submersible Autonomous Vessel for Intelligence, Operations and Reconnaissance, is India's first indigenously developed semi-submersible autonomous vessel designed specifically for anti-submarine warfare surveillance. The system is an unmanned, self-powered maritime platform capable of independent ocean patrols for extended periods. According to the announcement, the vessel operates silently beneath the sea surface using a sophisticated hydrophone array to listen for submarines and underwater threats. The platform transmits intelligence continuously to Naval command centres ashore and aboard ships without human presence onboard, combining persistent autonomous surveillance with lower operating costs compared to conventional anti-submarine warfare frigates, which cost several thousand crore rupees to build and maintain over their service life.
The announcement states that the company estimates the overall addressable market for autonomous maritime systems at approximately USD 10 billion by 2032, based on publicly available information. This estimate reflects market projections for the global autonomous maritime systems sector, described in the announcement as one of the fastest-growing segments in the worldwide defence industry. The announcement notes that actual programme values remain subject to Government procurement decisions and that market estimates are indicative.
Impact on Investors
The Make-II Prototype Sanction Order represents a material contract win for the company, opening a new revenue stream in the autonomous maritime warfare domain. Investors will note that the award provides formal Government backing for prototype development under one of India's most progressive defence procurement frameworks, which includes documented commitment to procure successful prototypes at scale. The framework significantly reduces technology and commercialisation risk compared to speculative defence projects, as procurement intent is embedded in the sanction order itself. The company has disclosed that many building blocks forming part of the critical technology are manufactured in-house by Apollo Micro Systems Limited, which investors will observe indicates vertical integration in key technology components and reduces dependence on external suppliers for core system elements.
Investors should note that the filing does not disclose the specific contract value, development timeline, or prototype delivery milestones. The announcement states that market estimates for autonomous maritime systems are indicative and that actual programme values remain subject to Government procurement decisions. Shareholders will observe that this award expands the company's addressable market from its existing defence electronics and mission-critical systems portfolio into the rapidly expanding autonomous maritime and underwater warfare systems segment. The award also represents validation of the company's indigenous technology development capabilities, which may strengthen its competitive positioning for future Make-II, Make-III, and capital procurement opportunities in the defence sector, though the timing and scope of such future opportunities cannot be inferred from this announcement.
Sector / Market Context
India's defence procurement market has evolved significantly under the Defence Acquisition Procedure framework, which prioritises indigenous development and manufacturing. The Make-II category specifically targets advanced capability development by private Indian companies with Government commitment to procure successful prototypes, reducing financial risk for developers and accelerating technology indigenisation. This framework has been positioned as a key mechanism for building India's defence industrial base and reducing dependence on imported defence systems. The category sits between Make-I (for startups and MSMEs) and Make-III (for capital procurement from industry), allowing established defence manufacturers like Apollo Micro Systems to undertake complex systems development with formal Government backing.
The Indian Ocean Region holds significant strategic and commercial importance. According to publicly available data cited in the announcement, approximately 95% of India's trade by volume and nearly 68% by value is transported by sea. The Indian Ocean Region handles nearly 100,000 merchant vessel transits annually, carries approximately 30% of global containerised cargo, and facilitates 42% of world crude oil trade. As submarine deployments and undersea threats continue to grow in the region, persistent underwater surveillance and anti-submarine warfare capabilities have become central priorities for maritime security. The autonomous maritime systems market is among the fastest-growing segments in the worldwide defence industry globally, with leading naval powers including the United States, United Kingdom, Australia, and China already deploying autonomous maritime systems as core components of their naval strategy. India's development of indigenous autonomous maritime capabilities under the Make-II framework reflects this global strategic trend.
