Expansion of Australia’s HIMARS Capabilities
The United States Department of State has green-lit a significant enhancement of Australia’s military capabilities via the approval of a Foreign Military Sale (FMS) comprising additional Lockheed Martin M142 High Mobility Artillery Rocket Systems (HIMARS). The Defense Security Cooperation Agency (DSCA) announced this approval on September 30.
Details of the Proposed Sale
- Quantity and Equipment: The proposed sale encompasses 48 HIMARS units along with ancillary equipment, including resupply vehicles and trailers.
- Estimated Value: The deal is valued at approximately USD 705 million.
Strategic Implications
This transaction, pending Congressional approval, represents Australia’s third and largest HIMARS procurement, effectively increasing its HIMARS arsenal to a total of 90 systems. The prior contracts involved:
- 2022 Order: 20 HIMARS units
- 2023 Order: 22 HIMARS units
In terms of cumulative value, Australia’s HIMARS acquisitions, including the latest procurement, are estimated around USD 2 billion. Previous purchases have also included munitions such as the Guided Multiple Launch Rocket System (GMLRS) across various configurations.
Operational Integration
The Australian Department of Defence has indicated that initial deliveries of HIMARS units have already commenced. As of March 2025, the Australian Army officially received two HIMARS systems, which are now integral to the operational framework of the 10th Brigade. This brigade, headquartered in Adelaide, was reconstituted in 2024, specifically designated as the army’s long-range fires unit.
Delivery Timeline
The delivery schedule for the 42 HIMARS units ordered in 2022 and 2023 is projected to conclude by 2027, aligning with enhanced operational readiness goals.
This robust expansion of HIMARS capabilities underscores Australia’s commitment to bolstering its defense posture in the Indo-Pacific region, enhancing not only its sovereign capabilities but also its interoperability with U.S. and allied forces.
