The Hobart-class guided-missile destroyers were developed under Project SEA 4000 to restore the Royal Australian Navy’s high-end integrated air defense capability, filling the strategic gap left by the retirement of the Perth-class. Based on the proven Spanish Navantia F100 design, the class was selected for its balance of established technology and adaptability, then modified for Australian conditions with enhanced range and habitability. While the hulls were assembled in South Australia by ASC through the AWD Alliance, the ships' primary purpose is centered on the American-designed Aegis Combat System, which allows them to track and engage over 100 targets simultaneously. This fusion of a Spanish-designed platform and advanced US sensors provides a sophisticated "air defense bubble" for naval task groups while serving as a multi-role combatant capable of anti-submarine and surface warfare across the Indo-Pacific.
Anzac Class is a long-range frigate capable of air defence, surface and undersea warfare, surveillance, reconnaissance and interdiction.
