Northrop Grumman Corporation has announced receipt of a US Navy contract for the production of acoustic nose arrays for the MK54 lightweight torpedo in support of Navy and foreign military sales requirements. The initial scope is for 428 nose arrays, which can expand to 3000 units. The Foreign countries mentioned in the contract include the Royal Australian Navy and the Indian Navy.
The American Defence Security Cooperation Agency notification to the U.S Congress indicated sale of 35 Mk-54 torpedoes including spares and logistical support to India at a price of $ 86 million. The submarine hunting torpedoes will be deployed by the Indian Navy on its eight P-8I Neptune long range maritime reconnaissance aircraft being acquired from Boeing.
The MK54 can also be deployed from a surface ship, helicopter or fixed wing aircraft to track, classify and attack underwater targets.
The company has produced 550 MK50 lightweight torpedoes and 491 MK48 Advanced Capability (ADCAP) heavyweight torpedoes in past. It is also a lead designer for the current MK48 ADCAP Mod 7 Common Broadband Advanced Sonar System upgrade in the early 2000s.
