Explanation:

• Recently, the U.S. Department of State has approved a possible sale of 16 Mk 54 lightweight torpedoes to India.
• The Mark 54 Lightweight Hybrid Torpedo is a standard anti-submarine warfare torpedo developed by Raytheon and introduced in 2004. It combines the homing section of the Mk 50, and the warhead and propulsion of the Mk 46 improved for better performance in littoral waters.
• It can be deployed from surface ships, helicopters or fixed wing aircraft and can track, classify and attack underwater targets.
• The torpedoes will improve India’s capability to conduct anti-submarine warfare missions and serve “as a deterrent to regional threats and to strengthen [India’s] homeland defence.
• Harpoon Block II Missile can be used against a wide variety of land-based targets, including coastal defense sites, surface-to-air missile sites, exposed aircraft, port/industrial facilities and ships in port. Hence statement 3rd is incorrect.
