The SM-2 IIIC missiles have a range of 160 kilometers, while the SM-6 missiles can reach up to 370 kilometers, showcasing their advanced capabilities.

In addition to the missile acquisition, Australia is set to produce its own long-range strike missiles in collaboration with Norwegian defense firm Kongsberg, expected to feature a range exceeding 275 kilometers.

Furthermore, the Australian government plans to invest an additional 11.1 billion Australian dollars into its combat fleet over the next decade, partly as a deterrent against China.

Australia has signed a significant $7 billion defense agreement with the United States to bolster its air and missile defense capabilities amid escalating global tensions.

The announcement was made by Defence Industry Minister Pat Conroy in Washington, following his attendance at the NATO Defence Ministers' meeting.

The deal includes the acquisition of hundreds of advanced SM-2 IIIC and SM-6 missiles, which can be launched from both land and naval platforms.

These missiles will significantly enhance the long-range capabilities of Australia's naval fleet, particularly the Hobart-class destroyers and future Hunter-class frigates.

According to Minister Marles, these advanced weapons will be capable of engaging sea, land, and air targets at long ranges, thereby improving Australia's ballistic missile defense.

The deployment of these missiles on Australia's naval vessels is planned, although specific timelines were not disclosed due to operational security concerns.

This acquisition builds on Australia's previous use of earlier SM-6 versions, with the current purchase initiated after receiving initial approval from the U.S. State Department in 2021.

This strategic move comes in response to rising tensions in the Indo-Pacific region, particularly following China's recent test of an intercontinental ballistic missile.

Defence Minister Richard Marles highlighted that Australia is facing its most complex geo-strategic environment since World War II, emphasizing the necessity of this investment as a deterrent against potential adversaries.
