Overview

• The Australian Army successfully launched a Lockheed Martin-developed PrSM from a HIMARS launcher at Mount Bundey two years ahead of schedule, achieving pinpoint accuracy at ranges beyond 300 miles.
• A 2025 Memorandum of Understanding between Australia and the U.S. activates co-development, production, and sustainment of PrSM, with future upgrades planned to push its range past 1,000 kilometers.
• Australia ordered 42 HIMARS launchers and received its first batch two months early, enhancing its land-and-sea strike options under the National Defence Strategy.
• The U.S. Army executed a rapid HIMARS infiltration exercise to Christmas Island during Talisman Sabre 2025, validating airlift-and-move tactics that boost survivability and extend munition reach.
• These joint initiatives strengthen deterrence in the Indo-Pacific by combining long-range precision fires with accelerated modernization and allied interoperability in response to China’s naval expansion.
