Background: The Indian Navy has been consistently upgrading its fleet to counter underwater threats. This includes the induction of advanced sonar systems and torpedoes. Current Context: In a significant move towards bolstering its anti-submarine warfare (ASW) capabilities, the Indian Navy is set to receive the first batch of indigenous lightweight torpedoes, 'Advanced Torpedo Defence System' (ATDS), by the end of July 2026. These torpedoes are designed to detect, classify, and neutralize enemy submarines. Impact: The induction of these indigenous torpedoes will significantly enhance the Navy's ASW prowess, reducing reliance on imported systems and strengthening India's maritime defense posture against underwater threats in the Indian Ocean Region.

Background: India's Defence Research and Development Organisation (DRDO) is at the forefront of developing advanced missile systems for the armed forces. This includes a range of surface-to-air missiles (SAMs) for air defense. Current Context: DRDO conducted a successful developmental test of a new generation surface-to-air missile from the Integrated Test Range, Chandipur, Odisha, on July 19, 2026. The missile is designed to intercept a wide range of aerial threats, including fighter aircraft, drones, and cruise missiles, at medium ranges. Impact: This successful test marks a significant milestone in India's air defense capabilities. The new SAM will enhance the survivability of naval fleets and ground forces by providing robust protection against advanced aerial threats, further bolstering national security.
