The Royal Australian Navy (RAN) commissioned the guided-missile destroyer HMAS Hobart in 2015. The Hobart is equipped with the Aegis combat system, incorporating the state-of-the-art AN/SPY 1D(V) phased-array radar. Australia plans to acquire a total of three Aegis-equipped ships for fleet air defense. Considering the security environment in the Asia-Pacific region, however, Australia should consider using its Aegis-equipped destroyers not only to enhance its domestic defense capabilities, but also to ensure the peace and security of the region by working side-by-side with its Ageis-equipped allies.
The RAN can both defend itself domestically and enhance regional security by conducting ballistic-missile surveillance and sharing its intelligence with the United States, Japan, and South Korea. Although the RAN does not have the capability to shoot down ballistic missiles, the AN/SPY 1D(V) radar on its Aegis-equipped ships can detect ballistic missiles from North Korea or China if properly stationed (though a software upgrade may be required).
