SEA 5000 Future Frigate The SEA 5000 Future Frigate is an Australian naval program to replace the Anzac-class frigate fleet with a class of guided-missile frigates intended for anti-submarine warfare and multi-role operations. The program involves collaboration among Australian Defence Force entities, international shipbuilders, and domestic industry to integrate advanced Aegis Combat System, sonar, and missile technologies while meeting strategic requirements of the Royal Australian Navy and interoperability with partners such as the United States Navy, Royal Navy, and Royal Canadian Navy.
SEA 5000 originates from Australian defence planning documents influenced by events such as the 2016 Defence White Paper, the 2017 update, and assessments from the Australian Strategic Policy Institute. Procurement decisions referenced precedents like the Hobart-class destroyer, Air Warfare Destroyer project, and experiences with the Anzac-class frigate and Fremantle-class patrol boat. Key stakeholders include the Department of Defence, Capability Acquisition and Sustainment Group, and shipbuilding firms including BAE Systems and ASC Pty Ltd. International rival bids drew on designs from Navantia, Fincantieri, Damen Group, STX France, Daewoo Shipbuilding & Marine Engineering, Mitsubishi Heavy Industries, and Samsung Heavy Industries.
The design emphasizes survivability, signature reduction, and growth margins informed by lessons from the Type 26 frigate, Hobart-class destroyer, FREMM multipurpose frigate, and MEKO family. Hull form and stealth features echo concepts tested by DST Group and modelled alongside comparative designs like the Iver Huitfeldt-class frigate and Karel Doorman-class frigate. Shipboard systems plan integration of combat systems comparable to the Aegis Combat System, AN/SPY-1, and variants used on Arleigh Burke-class destroyer, with Combat Management Systems interoperable with Link 11, Link 16, and Link 22. Accommodation, aviation facilities, and mission bays reference standards from MH-60R Seahawk deployments, NH90 operations, and the MH-60 Romeo community.
Planned armament suites consider vertical launch systems compatible with missiles like the RIM-162 ESSM, SM-2, and future Tomahawk or hypersonic interceptors, with anti-ship capability comparable to launchers fielded by Exocet and Harpoon users. Anti-submarine warfare envisages integrated sonar arrays akin to the Kingdom of the Netherlands' CAPTAS family, towed array systems used by Royal Netherlands Navy units, and hull-mounted sonar similar to those on Type 23 frigate. Close-in defense will take cues from systems like the Phalanx CIWS and SeaRAM. Electronic warfare and sensor suites draw from technologies fielded by Thales Group, Raytheon, BAE Systems, Northrop Grumman, Lockheed Martin, and Saab AB.
Propulsion options evaluated include Combined Diesel Electric and Gas (CODLAG), Combined Diesel and Gas (CODAG), and CODLOG arrangements with gas turbines from Rolls-Royce or General Electric and diesel engines from MAN Energy Solutions or MTU Friedrichshafen. Performance targets reference transit speeds and endurance similar to the Type 26 frigate, FREMM frigate, and Oliver Hazard Perry-class frigate, aiming for high sustained speeds, range for Indo-Pacific operations, and quiet signatures for ASW tasks informed by studies from DST Group and acoustic research from CSIRO.
Construction plans integrate workshare across Australian yards with technology transfer, workforce development, and industrial participation modeled on prior programs such as the Collins-class submarine program, Air Warfare Destroyer project, and the Hunter-class frigate build. Contracting approaches reference arrangements used by Naval Group and BAE Systems on international frigate programs, while industrial partners include Austal, Babcock International, Forgacs Marine & Defence, and local suppliers coordinated through the Australian Industry Capability framework and union stakeholders like the Maritime Union of Australia.
SEA 5000 program timelines align with vessel entry into service in the 2020s–2030s to replace Anzac-class frigate retirements, with procurement scheduling influenced by budget commitments from the Commonwealth of Australia and periodic reviews such as the Defence Strategic Update and Integrated Investment Program. Cost estimates draw on comparative data from the Hobart-class destroyer and Hunter-class frigate programs, with lifecycle cost modelling performed by the Australian National Audit Office and oversight from parliamentary committees. Contingency planning reflects lessons from cost growth in Air Warfare Destroyer project and schedule delays in multinational construction like the F-35 Lightning II program.
The frigates will be configured for anti-submarine warfare, air defence escort, maritime security, and humanitarian assistance, interoperating with platforms such as HMAS Canberra (LHD) amphibious ships, Collins-class submarine, E-7A Wedgetail, and allied carriers like USS Gerald R. Ford (CVN-78) and HMS Queen Elizabeth. Doctrine development references coalition operations in exercises like RIMPAC, Exercise Talisman Sabre, and Malabar, and is informed by strategic concepts from the Five Eyes partnership and regional security dialogues involving ASEAN and the Quadrilateral Security Dialogue.
SEA 5000 is positioned to influence Australia’s shipbuilding base, sovereign capability, and maritime industry policy, shaping partnerships with nations including United Kingdom, United States, Japan, France, and Germany. Industrial outcomes aim to bolster supply chains involving firms such as Thales Australia, Raytheon Australia, Lockheed Martin Australia, and research collaborations with institutions like Australian Maritime College, University of New South Wales, and Commonwealth Scientific and Industrial Research Organisation. The program bears implications for regional balance, defense diplomacy, and procurement reform debated in forums including the Parliament of Australia and analyses by think tanks like the Griffith Asia Institute and Lowy Institute.
