Hunter-class frigate

Hunter-class frigate. The Hunter-class is a future class of frigates under development for the Royal Australian Navy as part of the SEA 5000 program. Designed based on the Global Combat Ship concept by BAE Systems, the vessels are intended to replace the aging Anzac-class frigates. The class represents a cornerstone of Australia's naval modernization and a significant investment in sovereign shipbuilding capability.

Development and design

The Hunter-class program originated from the Royal Australian Navy's Project SEA 5000, which sought a new anti-submarine warfare frigate. In 2018, the Australian Government selected the design by BAE Systems Maritime – Naval Ships, a derivative of the Type 26 frigate being built for the Royal Navy. Key design adaptations for Australian service include integration of the CEA Technologies CEAFAR2 phased array radar and the Saab Group 9LV combat management system. The design phase involved extensive collaboration between BAE Systems, the Department of Defence (Australia), and local industry partners like ASC Pty Ltd to meet specific requirements for operations in the Indo-Pacific.

Construction and specifications

Primary construction occurs at the Osborne Naval Shipyard in South Australia, under the lead of BAE Systems Australia. The vessels feature a steel hull and aluminum superstructure, with a full-load displacement of approximately 8,800 tonnes, making them one of the world's largest frigates. Propulsion is provided by a CODAG system centered on a Rolls-Royce MT30 gas turbine, supported by four MAN Energy Solutions diesel generators. The principal armament is a 32-cell Mark 41 Vertical Launching System capable of launching a variety of missiles, including the Standard Missile 2, RIM-162 ESSM, and future Tomahawk land-attack missiles.

Service history and deployment

As of 2024, no Hunter-class vessels have been commissioned into the Royal Australian Navy. The first of class, HMAS *Hunter*, is scheduled to be laid down in the late 2020s, with entry into service anticipated in the early 2030s. The planned operational service will see the frigates undertake key roles within the Australian Defence Force, including protecting Australian Navy task groups, contributing to regional security partnerships like ANZUS, and conducting independent freedom of navigation operations. Their advanced anti-submarine warfare capabilities are deemed critical for operations in areas like the South China Sea.

International variants and exports

The parent design, the Type 26 frigate, has been selected by the Royal Navy and the Royal Canadian Navy under its Canadian Surface Combatant program. While the Hunter-class itself is a bespoke variant for Australia, its development has strengthened the industrial and design partnership between BAE Systems and Australian Defence Industry. The program has been presented as a model for technology transfer, with potential for Australian companies to supply components for allied programs. No direct exports of the Hunter variant have been announced, though its systems, like the CEA Technologies radar, are marketed internationally.

Criticism and controversies

The program has faced significant scrutiny over rising costs and schedule delays, with reports by the Australian National Audit Office highlighting concerns about value for money. Critics, including former Royal Australian Navy personnel and defense analysts, have questioned the vessel's size, complexity, and suitability compared to other designs like the Japanese Maritime Self-Defense Force's Mogami-class frigate. There have been ongoing debates in the Australian Parliament and media regarding the impact of delays on naval capability, especially amid rising tensions in the Indo-Pacific region involving China and the United States Navy.
