Australia has committed to joining the development program for PrSM Increments 3 and 4, which will see the missile reach a range of around 1,000 km (620 mi.).
Lockheed Martin has been selected to deliver the Air6500 phase 1 project, which will develop a sovereign joint air battle management system from Australia.
The Australian Defense Department will spend more than $2 billion on Tomahawk, AARGM-ER, Spike, additional HIMARS and PrSM to boost its missile capabilities.
