    The Hobart Class Air Warfare Destroyer (AWD) will deliver an affordable, effective, flexible and sustainable Air Warfare Destroyer capability for the security of Australia.
    The 2000 Defence White Paper stated the Australian Defence Force would replace the Navy's FFGs with a class of at least three air defence capable ships, the new Air Warfare Destroyers.
    The Air Warfare Destroyer Program will provide the Royal Australian Navy (RAN) with one of the world's most capable all purpose warships. In selecting the F100 as the baseline platform design and coupling it with the Aegis combat system, the Australian Government has ensured tomorrow's Navy has the best equipment to defend Australia and its national interests.
    These Hobart Class AWDs will provide air defence for accompanying ships in addition to land forces and infrastructure in coastal areas, and for self-protection against missiles and aircraft. The Aegis Combat System incorporating the state-of-the-art phased array radar, AN/SPY 1D(V), in combination with the SM-2 missile, will provide an advanced air defence system capable of engaging enemy aircraft and missiles at ranges in excess of 150km.
    The AWDs will carry a helicopter for surveillance and response to support key warfare areas. The surface warfare function will include long range anti-ship missiles and a naval gun capable of firing extended range munitions in support of land forces.
    The Hobart Class will also conduct Undersea Warfare and be equipped with modern sonar systems, decoys, surface-launched torpedoes and an array of effective close-in defensive weapons.
    These capabilities ensure the AWDs have the layered defensive and offensive capability required to counter conventional and asymmetric threats.

    Latest News on the AWD Project

    Ship 1 – The future destroyer Hobart

    Ship 1 is now fully consolidated, meaning all 31 blocks are joined on the hardstand at the South Australian Government's Common User Facility (CUF) in Adelaide. The CUF is located within the Techport Australia precinct adjacent to the ASC Shipyard and is where all three destroyers will be consolidated and launched.
    Work is underway on the internal fitout including installing diesel generators, main propulsion diesel engines, gas turbines and gearboxes and electrical switchboards.
    Taylor Bros has a team working on the accommodation compartments of the ship to install a range of products including cabin modules, furniture, galley, pantry, refrigerated spaces and laundry equipment.
    Load-out of the Hobart Class Combat System has commenced on Ship 1. In April 2014, six strike-length missile modules for the Vertical Launch System (VLS) were installed. The VLS MK41 modules are a critical part of the combat system which will enable the destroyers to execute air warfare and ship self-defence tasks.

    Ship 2 – The future destroyer Brisbane

    Following the keel-laying ceremony for Brisbane in February 2014, the consolidation process has progressed and there are now five keel blocks consolidated on the CUF hardstand.
    Block production for Brisbanecontinues at three Australian shipyards: BAE Systems (Victoria), Forgacs (New South Wales), and ASC (South Australia). The AWD Alliance has taken delivery of Brisbane's mast from local Port Adelaide company, MG Engineering.

    Ship 3 – The future destroyer Sydney

    Construction is underway on hull blocks for Ship 3, Sydney, at BAE Systems (Victoria); Forgacs (New South Wales) and work at ASC has also commenced. The mast is under construction at MG Engineering (Port Adelaide) andSydney's keel blocks will arrive from Navantia (Spain) mid 2014.

    Delay

    In October 2010, the 20 by 17 metre (66 by 56 ft) central keel block manufactured by BAE for Hobart was found to be distorted and incompatible with other hull sections. The cause of the fabrication errors is unknown: BAE blamed incorrect drawings from designer Navantia, while the AWD Alliance claimed the other two shipyards have not experienced similar problems, and believe first of kind manufacturing errors were made by BAE. The delay in reworking the keel block was predicted to set construction back by at least six months.
    In late May 2011, the government announced that the delay in building Hobarthad increased to between one and two years. An additional nine month delay was announced in September 2012, this was intended to create a better transition of labour from the destroyers to following shipbuilding projects (replacements for the Collins class submarines and the Anzac class frigates), and achieve some savings in the federal budget.

    Originally, the Hobart class destroyers were planned to be operational between December 2014 and June 2017. However, the ongoing delays have prompted the Australian government to announce revised entry to service dates in September 2012: Hobart will commission in March 2016, Brisbane is due in September 2017, and Sydney in March 2019. As a result of further delays and growing costs, the Hobart class destroyer project was added to the Government's "Projects of Concern" list in June 2014.

    The Hobart class is a ship class of three air warfare destroyers (AWDs) being built for the Royal Australian Navy (RAN). Planning for a class to replace the Adelaide class frigates and restore the capability last exhibited by the Perth class destroyers began by 2000, initially under acquisition project SEA 1400, which was redesignated SEA 4000. Although the designation "Air Warfare Destroyer" is used to describe ships dedicated to the defence of a naval force (plus assets ashore) from aircraft and missile attack, the planned Australian destroyers would also be able to operate in anti surface, anti submarine, and naval gunfire support roles.
    Planning for the Australian Air Warfare Destroyer (as the class was known until 2006) continued through the mid-2000s, with the selection of the Aegis combat system as the intended combat system and ASC as the primary shipbuilder in 2005. In late 2005, the AWD Alliance was formed as a consortium of the Defence Material Organisation, ASC, and Raytheon. Between 2005 and 2007, Gibbs & Cox's Evolved Arleigh Burke class destroyer and Navantia's Álvaro de Bazán class frigate competed for selection as the AWD design. Although the Arleigh Burke design was larger and more capable, the Álvaro de Bazán design was selected in June 2007 as it was an existing design, and would be cheaper, quicker, and less risky to build. Three ships were ordered, the contract included an option to order a fourth destroyer, but this has not been exercised.

    Each ship will be assembled at ASC's facility in Osborne, South Australia from 31 pre-fabricated modules (or blocks) built at ASC and other sites. NQEA Australia and the Forgacs Group were selected in May 2009 to construct the additional modules, but within two months, the modules assigned to NQEA were reallocated to BAE Systems Australia. The first block completed by BAE was distorted and incompatible with other sections: disagreements over the cause of the error and growing delays in the project led the AWD Alliance to redistribute the modules again, with some to be built by Navantia.
    The destroyers were originally intended to enter service from 2014 onwards, but delays in construction have pushed this back by almost two years. The first ship, Hobart, will enter service in March 2016, Brisbane is due to commission in September 2017, and Sydney should be operational by June 2019.

    The contract for the ships was signed on 4 October 2007. The A$8 billion, three-ship deal included the option to order a fourth ship at a later date. This option was due to expire in October 2008. The Australian government sought to extend the offer into early 2009, so as to review the recommendations of the Defending Australia in the Asia Pacific Century: Force 2030 white paper due for completion at the end of 2008, and to enquire about acquiring a fourth Aegis system from the USN, before ordering or cancelling the fourth destroyer.
    The Navy League of Australia has consistently supported the acquisition of a fourth AWD. According to the Navy League, building a fourth destroyer would be relatively cheap (money for design and other start-up costs would already be spent), would keep Australian shipbuilders employed for longer (as there is a projected seven-year gap before construction starts on the next major warship replacement), and improve RAN capabilities (by offering increased flexibility and redundancy, particularly in the event of a Falklands War-like armed conflict).
    The Australian Minister for Defence announced on 20 January 2006 that the Air Warfare Destroyers will be named Hobart, Brisbane, and Sydney.

    Each ship's main weapon is a 48-cell Mark 41 Vertical Launch System. The cells are capable of firing the RIM-66 Standard 2 anti-aircraft missile or the quad-packed RIM-162 Evolved Sea Sparrow point-defence missile. The Force 2030 white paper indicates that the Hobart's Mark 41 launchers are likely to be equipped (either at construction or through later modification) to fire the RIM-174 Standard 6 anti-aircraft missile and the Tomahawk cruise missile.
    The missiles are supplemented by two four-canister launchers for Harpoon anti-ship missiles, and a BAE Systems Mark 45 Mod 4 5-inch gun with a 62-calibre barrel. The 5-inch gun has a maximum range of 23.6 kilometres (14.7 mi). Two Babcock Mark 32 Mod 9 two-tube torpedo launchers will be carried, and used to fire Eurotorp MU90 torpedoes at submarines. For close-in defence, the ships will carry an aft-facing Phalanx CIWS system, plus two M242 Bushmaster autocannons in Typhoon mounts sited on the bridge wings.
    In November 2006, the Australian Government commissioned research on whether the AWDs should be equipped with anti-ballistic missile capabilities, most likely linked to the United States Department of Defense's Aegis Ballistic Missile Defense System.
    The Hobarts will each initially carry a single S-70B-2 Seahawk helicopter. The helicopter will be replaced by the MH-60 Romeo version of the Seahawk once it enters RAN service. Two rigid hulled inflatable boats are carried.

    Amazing ship IMO. It can accomodate a strike VLS and the AMDR by the end of this decade during refits. Along with ANZACs they will provide formidable Air-defense.
