To develop a robust, cost-effective, and re-usable underwater target system for simulating submarine signatures and movement profiles. This will support effective testing, calibration, and training with anti-submarine torpedoes under realistic operational conditions. Anti-submarine warfare (ASW) capability is a critical component of naval defence.Presently, expendable or imported targets are used for testing torpedoes, which are either non-reusable or financially unsustainable. There is a need for an indigenous, re-usable underwater target that can emulate various submarine characteristics and be deployed repeatedly across naval ranges for extended use.
