The Air Warfare Destroyer (AWD), also known as project SEA 4000, is a project aimed at providing Australian Royal Navy with an advanced anti-air warfare (AAW) destroyer for the 21st century. The Australian Department of Defence has estimated that AWD project will cost AUD6 billion ($4.6 billion) considering three AWD destroyers. These ships will assume forward deployed troops protection from air threats, air defense for Navy task groups and generation of a coordinated air picture for fighters and surveillance aircraft. The new destroyer will be built around successful Lockheed-Martin's Aegis weapon system as the AWD core system. The Aegis selection was announced in August 2004 and was done influenced by the US Navy's experience with such a weapon system. Raytheon Australia was selected on 21 April 2005 as preferred bidder for AWD combat system-system engineer. On 31 May, 2005, the Australian government announced that ASC Pty Ltd was selected as preferred shipbuilder for the AWD project. Bath Iron Works, a Northrop-Grumman subsidiary, teamed up with ASC and will provide its expertise on AEGIS-equipped ships. The first AWD was envisaged to enter into service by 2013. In late January 2006 Lockheed Martin and Computer Sciences Corporation agreed to implement Aegis Open Architecture (AOA) solution to AWD destroyer. AOA exploits commercial computing technology.
