India intends to use the Mk 54 torpedoes on its P-8I patrol aircraft. The US State Department had in April 2020 approved the вЂForeign Military SaleвЂ™ to the Government of India of 16 MK 54 All Up Round Lightweight Torpedoes (LWT), three MK 54 Exercise Torpedoes.ДЄt the time, the Defense Security Cooperation Agency had said, 'The torpedoes will improve IndiaвЂ™s capability to conduct anti-submarine warfare missions and serve вЂњas a deterrent to regional threats and to strengthen homeland defense.' The torpedo has also undergone rigorous testing - over 25,000 high-fidelity simulation runs and has also been put through its paces during in-water testing. The MK 54 is carried by the US Navy and the Royal Australian Navy.ДЄs per Raytheon, the MK 54 combines the advanced sonar transceiver of the MK 50 torpedo with the legacy warhead and propulsion system of the older MK 46. The torpedo weighs around 608 pounds, while its warhead weighs around 96.8 pounds and is highly explosive.ДЄs per the US Director Operational Test and Evaluation, the primary use of this equipment is for offensive purposes when deployed by anti-submarine warfare aircraft and helicopters, and for defensive purposes when deployed by ships and against fast, deep-diving nuclear submarines and slow-moving, quiet, diesel-electric submarines. The MK 54 lightweight torpedo is a 12.75-inch (324 mm) anti-submarine warfare (ASW) torpedo used by the United States Navy.Д¬o-developed by Raytheon Integrated Defense Systems, the MK 54 is designed to operate in shallow waters and in the presence of countermeasures, it can track, classify and attack underwater targets. HereвЂ™s a better understanding of this weapon and how it will help the Indian Navy. The Ministry of Defence signed the contract with the US government on Thursday, said officials. The Defence Ministry has signed a Rs 423-crore contract with the United States for procurement of MK 54 torpedo to equip its P-81 maritime surveillance aircraft with anti-submarine capability.
