Apollo Micro Systems Gets Indian Navy Order to Develop Indigenous Autonomous Underwater Surveillance System

Apollo Micro Systems Limited (AMS) has received a Make-II Prototype Sanction Order (PSO) from the Indian Navy to develop SAVIOR-ASW (Semi-Submersible Autonomous Vessel for Intelligence, Operations and Reconnaissance). The project marks the company's entry into autonomous maritime and underwater defence systems and is one of its most significant indigenous defence contracts.

What Is the Make-II Prototype Sanction Order?

The Make-II category is part of India's Defence Acquisition Procedure (DAP), which encourages Indian companies to develop advanced defence equipment domestically.

A Prototype Sanction Order (PSO) allows a company to begin developing a prototype with the expectation that the Indian Navy will procure the system if it successfully meets operational requirements.

For Apollo Micro Systems, the order is an important milestone as it recognises the company's capability to build advanced defence technology under the Atmanirbhar Bharat initiative.

What Is the SAVIOR-ASW System?

The SAVIOR-ASW is India's first indigenously developed semi-submersible autonomous vessel designed for anti-submarine warfare (ASW) surveillance.

Key features include:

• Operates without any crew onboard.
• Patrols the sea independently for long durations.
• Uses hydrophone sensors to detect submarines and underwater threats.
• Sends real-time intelligence to Indian Navy command centres and naval ships. 

The system is designed to strengthen India's underwater surveillance capabilities while reducing dependence on manned naval platforms.

Why Is This Project Important?

The Indian Ocean Region (IOR) is one of the world's busiest maritime trade routes.

According to the company:

• Around 95% of India's trade by volume moves through sea routes.
• Nearly 42% of global crude oil trade passes through the Indian Ocean Region.
• About 100,000 merchant vessels transit the region every year.
• Nearly 30% of global container cargo is transported through these waters. 

As submarine activity increases in the region, continuous underwater surveillance has become increasingly important for India's maritime security.

How SAVIOR-ASW Can Benefit the Indian Navy

Apollo Micro Systems said the autonomous system can offer several operational advantages:

• Continuous underwater surveillance over large ocean areas.
• Lower acquisition and operating costs compared to conventional warships.
• Ability to deploy multiple autonomous vessels simultaneously for wider coverage.
• Allows high-value naval ships to focus on combat and strategic operations instead of routine monitoring. 

Apollo's Vision for Autonomous Maritime Defence

The company believes future naval operations will increasingly rely on autonomous technologies. Its vision focuses on three major areas:

• Autonomous swarms: Multiple unmanned vessels working together and sharing real-time information.
• AI-powered intelligence: Artificial intelligence analysing underwater acoustic and sensor data to identify potential threats quickly.
• Persistent surveillance: Long-duration monitoring at significantly lower costs than traditional naval platforms.
