Australia has announced a significant step to enhance its air and missile defence capabilities through an A$7 billion ($4.7 billion) partnership with the United States. This defence initiative involves the acquisition of advanced SM-2 Block IIIC and SM-6 long-range missiles, supplied by Raytheon, which will bolster the Australian Navy’s striking and defence capacities. The SM-6 missile, regarded as the most advanced naval air defence system in the U.S. arsenal, was recently tested by the Australian Navy during joint exercises with the U.S. in Hawaii. This cutting-edge missile provides robust defence against air threats, including ballistic missiles, and has been proven effective for targeting ships, ground assets, and even in air-to-air engagements.
Australian Defence Minister Richard Marles emphasized the strategic role of these missiles, stating that they would be integrated into the existing Hobart-class destroyers and the future Hunter-class frigates, providing the Australian Defense Force (ADF) with a versatile, long-range strike capability. This development, he noted, will significantly strengthen Australia’s capacity to protect its interests, providing a powerful defence against maritime, land, and air threats.
Australia’s decision aligns with its broader strategy to enhance its long-range precision strike abilities, especially within its northern defence bases. This shift represents Australia’s most extensive defence restructuring since World War II, prompted by the growing influence and regional competition between the U.S. and China. A recent review by the Australian government highlighted this “major power competition” as a source of potential conflict, underscoring the need for Australia to improve its deterrence and defensive reach.
Defence Industry Minister Pat Conroy also remarked on the gravity of Australia’s strategic environment, describing it as the most complex since World War II. To mitigate rising tensions in the Asia-Pacific, especially in the South China Sea, Australia and the U.S. are jointly upgrading key military bases in northern and western Australia, which offer closer proximity to potential flashpoints in the region. This defence partnership and infrastructure modernization underscore Australia’s commitment to maintaining stability and security in an increasingly challenging geopolitical landscape.
