Northrop Grumman Corporation announced today that it has been awarded $171 million by the US Navy for advance procurement long-lead time materials for LPD 21, the fifth amphibious transport dock ship in the San Antonio-class LPD 17 ship-building program.
LPD amphibious transports are use to transport and land military personnel, their equipment and supplies by embarked landing craft or amphibious vehicles.
Long-lead materials are said to consist of the main engines, generators, controllable pitch propellers and reduction gears. Advance procurement is necessary for these critical long-lead items in order to exercise vendor option rates.
To date, the first four ships awarded in the 12-ship LPD 17 program are under contract. LPD 17 and LPD 18 are presently under construction at all three locations of Northrop Grumman Ship Systems in New Orleans and Pascagoula and Gulfport, Mississippi.
The first ship is approaching 50 percent completion in unit erection at Avondale Operations in New Orleans. In October, the keel for the second ship, USS New Orleans, will also be laid at Avondale.
The LPD 17 amphibious transport dock ships are designed to be 208.4 metres long and 31.9 metres wide and will replace the functions of the LPD 4-, LSD 36-, LKA 113-, and LDT 1179-classes of amphibious ships.
