DDG1000 weaponry
DDG 1000 will have a sensor and weapons suite optimised for littoral warfare and for network-centric warfare. Northrop Grumman has put forward a solution based on a peripheral vertical launch system (PVLS).
The solution consists of 20 four-cell PVLS situated round the perimeter of the deck, rather than the usual centrally located VLS. This would reduce the ship’s vulnerability to a single hit.
The advanced vertical launch system (AVLS) that forms the basis of the PVLS is being developed by BAE Systems Land and Armaments and Raytheon and has been designated the mk57 VLS.
Missile systems under consideration include tactical tomahawk (intended to succeed Tomahawk TLAM), standard missile SM-3 and the evolved Sea Sparrow missile (ESSM) for air defence.
BAE Systems Land and Armaments has been awarded the contract to develop the EDM for the ship’s advanced gun system (AGS), building on development work carried out for DD-21.
It will be equipped with a fully automated weapon handling and storage system and a family of advanced munitions and propelling charges, including the GPS-guided long-range land attack projectile (LRLAP). Up to 900 rounds of LRAP ammunition will be carried.
Lockheed Martin has been awarded the contract for the LRAP EDM.
The family of munitions is expected to include land attack and ballistic projectiles. Technologies derived from the US Navy’s extended-range guided munition (ERGM), the US Army 155mm XM-982 projectiles and the DTRA 5in projectile are being studied for incorporation into the projectile suite.
BAE Systems Land and Armaments is developing advanced gun barrel technologies for the new AGS, with improvements to barrel life, overall system performance and life-cycle costs.
The ship’s close-in gun system (CIGS) will be the BAE Systems Land and Armaments 57mm mk110 naval gun. The gun has a firing rate of 220 rounds a minute and range of 14km (nine miles). Raytheon IDS is supplying the ship’s electro-optical / infrared suite which has five Lockheed Martin sensors and will provide 360° surveillance and gun fire control.
