The Hobart Class air warfare destroyers (AWD) are being built by AWD Alliance for the Royal Australian Navy (RAN). The air warfare destroyer programme, known as SEA 4000, will deliver three advanced multirole warships to replace the FFGs of the RAN.
The three AWDs will be named HMAS Hobart, HMAS Brisbane and HMAS Sydney. The first AWD is expected to be delivered in December 2014, and the second and third warships are slated for early 2016 and mid-2017 respectively.
The $8bn AWD project is the largest Defence procurement project ever undertaken in Australia. It is expected to create 3,000 jobs in Australia and also benefit thousands of companies based in the nation.
Air warfare destroyer programme
The Hobart Class AWD programme is intended to deliver an affordable, effective, flexible and sustainable air warfare destroyer platform to the RAN. The requirement for modern warships was established by the Kinnaird Review in 2003. Gibbs & Cox and Navantia submitted warship designs to the Commonwealth Government.
The Australian Government selected ASC as the shipbuilder for the programme in May 2005. In June 2007, the existing design of Navantia was selected as a platform for the AWD programme. ASC entered into an alliance-based contract with the Defence Materiel Organisation and Raytheon Australia. The project has passed critical design review in January 2010.
Hobart Class AWD design
"The AWD platform is based on the Navantia-designed F100 frigate."
The AWD platform is based on the Navantia-designed F100 frigate, which is in service with the Spanish Navy. The baseline design has been slightly modified for Australian use, including the displacement of the AWD being increased to 7,000t, and the hangar modified to accommodate a range of helicopters.
The range now includes powerful diesel engines combined with improved fuel tank arrangements. The design also incorporates a bow thruster to provide better manoeuvrability.
AWD construction
The AWD Alliance subcontracted the FORGACS group and NQEA Australia as the preferred suppliers to build 70% of the blocks. In June 2009, the work allotted to the NQEA was transferred to BAE Systems Australia due to financial obligations.
The ships are being built using a modular construction method. The hull blocks of three destroyers are being constructed at three shipyards, including ASC in Osborne, BAE Systems in Melbourne and Forgacs in Newcastle. The assembling, outfitting, equipment and systems installation and trial activities will be carried out at the newly opened ASC Osborne shipyard.
A total of 31 blocks are being constructed for each ship, of which 70% are built by BAE Systems and Forgacs, and the remaining by ASC. ASC's facility located northwest of Adelaide's CBD will fabricate nine blocks for each ship. Work is currently underway on six blocks including decking and superstructure components.
Work is in progress on seven of the 12 main keel blocks fabricated for each ship at Melbourne and Victoria facilities of BAE Systems. Forgacs will fabricate 10 blocks for each ship in Newcastle. Work is underway on five central blocks, including the superstructure. Accommodation modules for all the ships are being built by Taylor Brothers in Hobart.
In June 2010, AWD Alliance has signed a $25m contract with Toll North to transport 66 hull blocks from Newcastle and Melbourne to Osborne Shipyard for assembly. BlueScope Steel has been contracted to supply 3,000t of steel required for the ship construction.
Hobart Class AWD missions
The Hobart Class will provide air defence for vessels, land-based forces and infrastructure in coastal lines. It will also defend and destroy missiles and aircraft within a range of 150km. The destroyers can also be deployed in law enforcement operations, defence aid to the civil community, collection of environmental data, rescue operations and diplomatic roles.
The Hobart Class will be equipped with advanced sonar systems, decoys and surface-launched torpedoes for anti-submarine warfare (ASW) operations.
Hobart Class AWD weapon systems
The Hobart Class AWDs will be the first RAN warships to be equipped with the Aegis combat system. Aegis includes a SPY-1D(V) radar, Mk 41 vertical launch system (VLS), SM-2 standard missile and an open architecture (OA) combat system.
"The Hobart Class will provide air defence for vessels."
The AWD will also be armed with the SM-6 long-range anti-aircraft missile, the Harpoon anti-ship missile system and Mk32 Mod9 surface vessel torpedo tubes (SVTT) for MU90 torpedoes.
The AWD will be fitted with a BAE Systems Mk 45 5" 62 calibre gun and a Phalanx Block 1B close-in weapons system (CIWS).
AWD helicopter system
The Hobart Class will feature a flight deck and a hangar to allow the operations of helicopters and UAVs. The existing hangar design will be modified to carry a wide range of helicopters.
Hobart Class countermeasures
"The Hobart Class will be equipped with advanced sonar systems and decoys."
The destroyer will be equipped with a ES-3701 tactical radar electronic support measures (ESM) and surveillance system. In December 2008, the AWD Alliance awarded a contract for the supply of a decoy launching system to Terma. Four deck-mounted MK-137 130mm decoy launchers can fire decoys to deceive incoming anti-ship missiles. Other countermeasures include Nulka active missile decoy launchers and ASW torpedo decoys.
AWD sensors
The AWD's sensor suite will include AN/SPY-1D(V) phased array radar, horizon search radar, SAM Electronics X-band navigation radar, integrated hull-mounted and towed array sonar system, and VAMPIR infrared search and track (IRST) system.
Hobart Class propulsion
The AWD will be equipped with a combined diesel and gas (CODAG) propulsion system with two GE LM 2500 gas turbines and two diesel engines. The vessel will also be fitted with a bow thruster for improved manoeuvrability.
Hobart Class Air Warfare Destroyers - Naval Technology
Air Warfare Destroyer (AWD)
The Hobart Class Air Warfare Destroyer (AWD) will deliver an 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.
