The U.S. State Department has approved a potential $705 million foreign military sale to Australia for M142 High Mobility Artillery Rocket Systems (HIMARS).
According to a notification delivered by the Defense Security Cooperation Agency (DSCA) to Congress, the Australian government has requested 48 M142 HIMARS launchers, along with resupply vehicles, trailers, training rockets, communication systems, and a range of support services.
The deal also includes spare parts, engineering and logistics support, studies, surveys, and other elements of program assistance.
The proposed sale, the State Department said, “will support the foreign policy and national security objectives of the United States.” Australia is described as “one of the United States’ most important allies in the Western Pacific,” and its geographic position “contributes significantly to ensuring peace and economic stability” in the region.
The HIMARS system — manufactured by Lockheed Martin — is one of the U.S. Army’s most versatile and battle-tested rocket artillery platforms, capable of delivering precision strikes at extended ranges. It has become a key capability for U.S. forces and allied militaries worldwide, particularly in deterrence and rapid-response operations.
The DSCA said the acquisition “will improve Australia’s capability to meet current and future threats” while enhancing “interoperability with U.S. forces and other allied forces.” Australia intends to use the HIMARS systems to strengthen homeland defense, protect critical infrastructure, and expand long-range strike capacity in an increasingly contested security environment.
Australia “will have no difficulty absorbing this equipment into its armed forces,” the agency added.
U.S. officials emphasized that the proposed sale will not alter the basic military balance in the region but will contribute to maintaining a stable security architecture amid growing strategic competition. The decision reflects Washington’s broader strategy to deepen defense cooperation with key allies in the Indo-Pacific and to improve collective readiness against emerging threats.
The acquisition also aligns with Canberra’s ongoing defense modernization agenda, which includes expanding long-range strike capabilities, investing in advanced command-and-control systems, and strengthening cooperation with the United States, Japan, and other regional partners.
The principal contractors for the potential sale include Lockheed Martin in Grand Prairie, Texas; L3Harris Corporation in Melbourne, Florida; Leonardo DRS in Arlington, Virginia; and Oshkosh Corporation in Stafford, Virginia. At present, no offset agreements are planned, although any such arrangements will be determined during negotiations between Australia and the contractors.
The HIMARS package also includes non-major defense equipment such as M1084A2 resupply vehicles, M1095 trailers, and Low Cost Reduced Range Practice Rocket (LCRRPR) pods. These additions are designed to support training, operational readiness, and sustainment once the systems are fielded.
