The US State Department has approved the sale of 110 anti-radiation missiles to Australia, which will arm its Boeing EA-18G Growler Aircraft.

The package includes 70 Raytheon AGM-88B High Speed Anti-Radiation Missiles (HARM) and 40 AGM-88E Advanced Anti-Radiation Guided Missiles (AARGM), says the US Defense Security Cooperation Agency in a filing.

The value of the package is $137.6 billion. It also includes missile components, training equipment, and other services and systems.

"Australia is requesting these missiles for its Electronic Attack EA-18G Growler aircraft," says the DSCA.

"The proposed sale will improve Australia’s capability in current and future coalition efforts. Australia will use this capability as a deterrent to regional threats and to strengthen its homeland defense. Australia will have no difficultly absorbing these additional missiles into its armed forces."

Canberra operates 12 EA-18Gs, the electronic warfare variant of the F/A-18F Super Hornet.
