Royal Australian Air Force to acquire secret new AIM-260 air-to-air missiles
Australia’s Defence Minister Richard Marles said the Royal Australian Air Force will buy Lockheed Martin’s AIM-260A Joint Advanced Tactical Missile for F/A-18F Super Hornets, replacing Raytheon AIM-120C AMRAAM, and later for F-35A and EA-18G. The order is valued at A$736 million; a US approval earlier cited up to 450 missiles plus test vehicles for about US$3.16bn.
How this was made

The 30-second read
Why it matters
The announcement is a concrete procurement milestone: Australia becomes the first acknowledged non-US operator, with an approved purchase of up to 450 missiles plus integration and guided test vehicles, and a stated A$736m order value. This can affect defense procurement expectations and program execution sentiment for the missile prime and integration ecosystem.
Market read
A newly confirmed, first acknowledged non-US AIM-260A order provides a fresh defense procurement catalyst, with deal value and platform integration scope disclosed.
What to watch
The article emphasizes secrecy and development delays; traders may discount immediate earnings impact without clarity on delivery schedule, contract structure, and whether additional tranches are already funded.
Background
Australia’s RAAF has been developing plans to replace older AIM-120C AMRAAM missiles with the AIM-260A Joint Advanced Tactical Missile (JATM), a program under secret development since 2017.
Ticker impact
RAAF confirmed it will equip F/A-18F Super Hornets with Lockheed Martin’s AIM-260A JATM, an acknowledged first non-US order valued at A$736m.
Modest positive bias for LMT, more likely supportive than market-moving given the article’s single-country order framing.
The article provides deal size (A$736m) and program scope (integration across Super Hornets, later F-35A and EA-18G), but does not disclose margin, timing of cash flows, or broader contract follow-on beyond “tranches.”
Market effects
Signals continued BVR missile demand and modernization for allied air forces, reinforcing defense prime and missile-systems supply-chain narratives.
Australia’s procurement milestone may shift regional defense spending expectations and sustain sustainment/integration work for RAAF platforms.
First acknowledged non-US operator for AIM-260A can strengthen the program’s international credibility and future export prospects.
Counterpoint
The order may be only the first tranche, with delayed production and integration issues already noted, limiting near-term revenue visibility.
