U.S. Approves 450 AIM-260 Missiles for Australia to Extend F-35 Fighter Jets Combat Range.
The United States approved a $3.16 billion sale of up to 450 AIM-260 JATM missiles to Australia to extend allied air combat reach.
The January 2026 congressional notification clears Australia to move toward acquiring the AIM-260A Joint Advanced Tactical Missile, including test vehicles and full support infrastructure. The package combines $2.61 billion in missiles with $550 million in sustainment, training, and integration systems. Designed to replace AMRAAM, JATM introduces greater range, improved resistance to electronic warfare, and secure GPS guidance, aligning with Australia’s F-35A force modernization and coalition air operations.
Australia is set to acquire up to 450 AIM-260A JATM air-to-air missiles in a $3.16 billion U.S. sale, giving the RAAF a major boost in long-range air-combat capability and allied interoperability in the Indo-Pacific.

The notification was delivered to Congress on January 23, 2026, and published in the Federal Register on March 17. Because Australia falls under the U.S. 15-calendar-day congressional review category for these transfers, that formal notification stage has expired and the case can now move toward a negotiated Letter of Offer and Acceptance.
What Australia is buying is not simply a large missile lot. The official notice divides the package into $2.61 billion in major defense equipment and $550 million in support items, including ammunition containers, software, technical documentation, test equipment, training aids, repair-and-return support, transportation, site surveys, spares, and engineering assistance. Public technical disclosure remains deliberately narrow: the AIM-260 is described as a GPS-aided air-superiority missile with increased range and effectiveness over existing air-to-air weapons, using protected Precise Positioning Services through SAASM or M-Code, and incorporating anti-tamper measures to prevent software exploitation. The same notice states that the highest classification level in the release is SECRET, while U.S. Air Force budget documents keep further justification in classified annexes.
Even that limited disclosure is enough to establish the missile’s tactical logic. JATM is designed to widen the first-shot opportunity in beyond-visual-range combat, preserve lethality in a contested electromagnetic environment, and maintain relevance against increasingly capable electronic warfare. It is intended to replace the AMRAAM with better long-range performance and improved ability to defeat electronic-warfare jamming. When that kind of missile is paired with a stealth fighter that already combines advanced sensors, data fusion, and internal weapons carriage, the result is a meaningful shift in who can detect, decide, and engage first.
The inclusion of five Integration Test Vehicles and 30 Guided Test Vehicles is especially revealing because it shows Canberra is not treating JATM as a simple shelf purchase. The ITV is a modified missile used for captive tests, while the GTV replaces the warhead with telemetry equipment to capture missile-flight data during live fire. In operational terms, Australia is buying entry into the integration, validation, and tactics-development cycle from the start rather than waiting for a later retrofit. The package also includes KGV-135A embedded communications-security devices, which are high-speed encryptor/decryptor modules for wideband data protection.
The public notice does not identify the future launch platforms, but the most plausible operational match is Australia’s F-35A force. Australia has completed delivery of its 72 F-35As, based at Williamtown and Tindal and assigned to three operational squadrons plus No. 2 Operational Conversion Unit. The aircraft’s defining strengths are low observability, internal weapons carriage, advanced radar, electro-optical and infrared sensors, and rapid sensor-data fusion; just as importantly, the final nine aircraft delivered in December 2024 were the first in the fleet with Technology Refresh 3, the baseline for broader Block 4 growth. That does not prove immediate Australian JATM integration, but it makes the purchase strategically coherent.
Australia also has a very specific strategic reason to want a longer-ranged air-to-air missile now. The 2024 National Defence Strategy makes deterrence by denial the core of Australian defence planning and explicitly prioritizes defending Australia and its immediate region, deterring an adversary from projecting power through the northern approaches, and contributing with partners to Indo-Pacific security. In a theater defined by long distances, distributed bases, and coalition operations, air defense cannot rely on short-legged interception logic alone. A missile that pushes the engagement line outward directly supports the RAAF’s stated offensive and defensive counter-air missions.
The interoperability case is equally strong. The sale notice itself says JATM will improve interoperability between the United States and the RAAF, and recent exercises show exactly why that matters. During Exercise Magpie Lightning in northern Australia, U.S. Marine Corps F-35Bs trained with RAAF F-35As at Tindal in offensive counter-air, defensive counter-air, suppression of enemy air defences, and strike profiles, with both sides emphasizing a notably high level of interchangeability. A common next-generation air-to-air weapon would simplify not only logistics, but also shared tactics, mission planning, and engagement sequencing inside a coalition air package.
There is also an industrial and policy dimension to the case. The principal contractor is Lockheed Martin Missiles and Fire Control in Orlando, and the sale arrives as Canberra and Washington deepen missile cooperation across the broader guided-weapons enterprise. At AUSMIN 2024, both governments highlighted co-production work on GMLRS, a pathway toward cooperative work on the Precision Strike Missile, and a new integrated air and missile defense roadmap. JATM itself is not being offered here as an Australian co-production program, but the purchase still draws Australia deeper into the U.S. advanced-weapons ecosystem, including the software, security, sustainment, and test architecture around sensitive munitions. It also complements broader Australian efforts to modernize its combat air fleet, deepen allied force posture, and sharpen long-range deterrence in the Indo-Pacific.
Strategically, the significance of this case lies less in the headline quantity than in the kind of air battle Australia expects to fight. The RAAF’s F-35A fleet already sits at the center of Australia’s air-defense and strike posture, and Canberra is openly building an integrated, focused force for a harsher regional environment. Adding JATM gives that force a better chance to contest the outer edge of the fight before hostile aircraft can pressure Australian bases, key airborne enablers, and northern approaches. In practical military terms, Australia is buying distance, decision time, and a higher probability that allied fighters retain the initiative.
This is one of the most consequential Indo-Pacific air-combat cases of the year because it couples quantity with a serious operational support architecture. The official record shows a missile with increased range and effectiveness, protected navigation, anti-tamper security, dedicated integration and telemetry test rounds, wideband COMSEC hardware, and a full training and sustainment package. In an era when the AMRAAM is aging and coalition airpower must fight farther forward under heavier electronic attack, that is not a routine replenishment. It is a qualitative upgrade in allied air-superiority capacity.
