Australia is set to buy 220 Tomahawk cruise missiles from the US in a deal worth more than $1 billion.

Iran PressAsia: The US State Department has approved the sale of some 220 cruise missiles to Australia in a deal valued around 1 billion dollars.

The proposed sale, which requires sign-off from Congress, includes Tomahawk missiles and technical support.

The missiles will be used by the Virginia-class submarines Australia will acquire from the US under the Aukus defence pact.

The deal would enable the country "to reach out beyond our shores further and that's ultimately how we are able to keep Australia safe" the minister told the Australian Broadcasting Corporation (ABC).

The missiles could be initially deployed on Australia's Hobart-class destroyers before the first Aukus submarines are delivered, according to Austrailian media.

The Pentagon said the sale would "improve Australia's capability to interoperate with US maritime forces and other allied forces as well as its ability to contribute to missions of mutual interest".

The Aukus deal, unveiled on Monday in San Diego, binds together Australia, the UK and the US in a far-reaching defence alliance which will confront Chinese military expansion in the region. 219
