India had first got the anti-submarine MK54s from the U.S. for its Boeing P8I long range reconnaissance planes in 2012 for $45 million. The plane also carries the Boeing Harpoon missiles.
The U.S. Department of Defense's latest announcement said it awarded Raytheon Integrated Defense Systems, based at Portsmouth in Rhode Island, a $29.75-million modification to a previously awarded contract, which includes the production of the MK54 Mod 0 Lightweight Torpedo kits and related engineering and repair services for the upgrade of the Navy LWTs.
"This modification also involves foriegn military sales to India, Turkey and Australia," a notification from the U.S. Department of Defense said on Aug.31, 2015. "This option exercise provides the Navy with a quantity of 100 MK54 Mod 0 LWT kits including warranty and a quantity of 68 foreign military sales MK54 Mod 0 LWT kits including warranty and spares."
Although the 230-kg MK54 Mod 0 LWT is primarily intended as an anti-submarine torpedo for littoral scenarios, its basic capabilities includes operation in both shallow and deep water acoustic environmental conditions, and exceeds MK46 anti-submarine warfare capabilities in deep-water scenarios. It can be launched from a surface warship, a submarine, an aircraft or an helicopter
Work will be performed in Keyport, Washington (80 percent); and Portsmouth, Rhode Island (20 percent), and is expected to be completed by September 2017.
