The U.S. DSCA says Japan's package includes 50 JASSM-ER missiles, JASSM Anti-Jam Global Positioning System Receivers (JAGR) and relevant support systems.
The next increment of OASuW is the Hypersonic Air-Launched Offensive (HALO) weapon, first disclosed in a budget request in 2022 with prototypes expected this year.
The acquisition of the cruise missile helps Australia recover some of the long range striking power that the RAAF lost when the F-111Cs retired in 2011.
The acquisition plans, detailed April 3, are a component of the country’s €14.8 billion ($16.1 billion) increase in defense spending between 2022 and 2025.
Budget justification documents released by the Navy on May 29 list the Hypersonic Air-breathing Weapon Concept (HAWC) and the Supersonic Propulsion Enabled Advanced Ramjet (SPEAR) demonstrators as candidates for the Offensive Anti-Surface Warfare (OASuW) Increment II program.
