SPACE: A Cutting-Edge Facility for Sonar Testing and Evaluation in India


In a significant step towards enhancing India’s naval capabilities, the Department of Defence (R&D) and the Defence Research and Development Organisation (DRDO) have recently inaugurated a state-of-the-art facility called the Submersible Platform for Acoustic Characterisation and Evaluation (SPACE) at the Underwater Acoustic Research Facility in Kulamavu, Idukki, Kerala. This cutting-edge facility, set up by the Naval Physical & Oceanographic Laboratory of DRDO, is designed to serve as a premier testing and evaluation hub for sonar systems destined for the Indian Navy, a critical component of the country’s maritime defense strategy.

Importance of Sonar Systems in Naval Warfare

Sonar (Sound Navigation and Ranging) systems play a vital role in modern naval warfare, enabling the detection, tracking, and identification of submarines, surface vessels, and other underwater objects. These advanced acoustic sensors are essential for effective Anti-Submarine Warfare (ASW) operations, which are crucial in protecting a nation’s maritime interests and ensuring the safety of naval assets.

As the Indian Navy continues to expand its fleet and modernize its capabilities, the need for robust and reliable sonar systems has become increasingly paramount. The establishment of the SPACE facility reflects the DRDO’s commitment to developing and testing these critical technologies, ensuring that the Indian Navy is equipped with cutting-edge sonar systems to maintain a strategic edge in the maritime domain.

Key Features of the SPACE Facility

The SPACE facility is designed to be a comprehensive testing and evaluation hub for sonar systems, catering to the diverse needs of the Indian Navy. Some of the key features of this state-of-the-art facility include:

Floating and Submersible Platforms

The SPACE facility consists of two distinct assemblages: a floating platform that rests on the water surface and a submersible platform that can be lowered to depths of up to 100 meters using winch systems. This dual-platform design allows for the evaluation of complete sonar systems, enabling quick deployment and easy recovery of scientific packages, such as sensors and transducers.

Versatile Data Collection Capabilities

The SPACE facility is equipped with modern scientific instrumentation, allowing for the survey, sampling, and data collection of air, surface, mid-water, and reservoir floor parameters. This capability ensures that the facility can cater to a wide range of research and development needs, including the characterization of underwater environments and the assessment of sonar system performance in various conditions.

Advanced Data Processing and Analysis

The SPACE facility houses modern, well-equipped scientific laboratories, providing the necessary infrastructure for data processing and sample analyses. This advanced capability will enable researchers and engineers to conduct in-depth analysis of the collected data, leading to the development of more effective and reliable sonar systems for the Indian Navy.

Enabling Cutting-Edge Anti-Submarine Warfare Research

By providing a dedicated platform for the testing and evaluation of sonar systems, the SPACE facility will play a crucial role in advancing India’s Anti-Submarine Warfare research capabilities. This is a significant milestone in the country’s efforts to strengthen its naval defense capabilities and ensure the protection of its maritime interests.

Inauguration and Significance

The SPACE facility was officially inaugurated on April 17, 2024, by Dr. Samir V Kamat, the Secretary of the Department of Defence (R&D) and the Chairman of DRDO. This event marks a significant milestone in the development of India’s naval technology and underscores the country’s commitment to enhancing its maritime defense capabilities.

The inauguration of the SPACE facility is a testament to the DRDO’s efforts to foster technological innovation and support the Indian Navy’s operational requirements. By providing a state-of-the-art platform for the testing and evaluation of sonar systems, the DRDO is paving the way for the development of more advanced and reliable acoustic sensors, which will be crucial in ensuring the superiority of the Indian Navy in the maritime domain.
