Keltron advances indigenous underwater vessel with sonar integration

Keltron, the Kerala-based electronics manufacturing company, has commenced the integration of advanced sonar systems developed in-house for the Jalkapi underwater vessel project. The systems include both bow and flank array sonar configurations, which have been engineered to meet the operational requirements of India's indigenous underwater platform.

The sonar systems represent a critical component of the Jalkapi vessel's sensor suite, enabling underwater detection and surveillance capabilities essential for naval operations. By developing these systems domestically, the project reduces dependency on foreign suppliers and strengthens India's self-reliance in defence technology.

The integration phase is expected to involve comprehensive testing and validation procedures to ensure the sonar systems perform optimally within the vessel's operational environment. Successful integration would represent a major achievement for India's indigenous defence development ecosystem, demonstrating capability in one of the most technologically demanding areas of underwater warfare systems.

The Jalkapi project reflects India's broader commitment to developing advanced indigenous defence platforms. The involvement of Keltron, a public sector undertaking with extensive experience in electronics and systems integration, underscores the role of domestic industry in meeting the country's strategic maritime requirements.
