First Multinational HIMARS Launch on Australian Soil Highlights Interoperability, Modernization

Multinational forces demonstrated integrated fires and maneuver capabilities across multiple domains during a combined joint live-fire exercise as part of Exercise Talisman Sabre 25 in Queensland, Australia, July 14, 2025. 

The event brought together forces from several nations to synchronize long-range fires, armor movements and air defense in a realistic scenario designed to strengthen interoperability and regional deterrence.  

Senior military leaders and international observers watched as partner nations coordinated across all areas of the battlespace. 

The High Mobility Artillery Rocket System's live-fire component underscored the ability of partner forces to rapidly deploy and share targeting data. 

"For me, it's like-minded nations bringing together their modern technology on the battlefield to train and work together," said Army Lt. Gen. Matthew McFarlane, commanding general of I Corps. "What we have in mind is that no matter which country's sensor detects a target, any other partner nation can engage the target." 

The scenario began with Marine Corps F-35B Lightning II joint strike fighters executing an initial airstrike to neutralize enemy air defenses. With air superiority established, HIMARS from the Australian Defence Force's 10th Brigade, U.S. Army's 17th Field Artillery Brigade and Singapore Armed Forces moved from concealed positions to deliver precision long-range fires.  

Targeting data was provided by a multinational intelligence, surveillance and reconnaissance enterprise, including Australian integrator unmanned aerial system platforms. 

This event marked a historic first for the Australian army, its first HIMARS launch on home soil in cooperation with regional partners. The exercise also reflected Australia's ongoing modernization efforts with domestically produced munitions expected to support future integration. 

"Opportunities to live fire and train alongside our allies and partners as part of Talisman Sabre is critical to building true interoperability," said Army Lt. Col. Edward Guelfi, commander of the 1st Battalion, 3rd Field Artillery Regiment, 17th Field Artillery Brigade. "These moments forge trust, sharpen readiness and send a clear message. We are united, capable and ready to deter any threat together." 

U.S. HIMARS crews fired guided multiple launch rocket systems to engage enemy targets identified during the preceding air assault, reinforcing the importance of a shared targeting picture. Following successful deep fires, joint forces shifted to the close battlespace. M777A2 155 mm howitzers from the Marine Corps and Australian Defence Force provided suppressive fires, clearing the way for South Korea K9A1 and K1A2 systems to deliver counterbattery effects and lead a simulated armored assault. 

Guelfi highlighted the excitement and motivation felt by the soldiers in his brigade for the opportunity to train alongside the Australian Defence Force and Singapore Armed Forces.  

"One key takeaway was how quickly our teams adapted to each other's systems and procedures, highlighting that interoperability isn't just about equipment, it's about people, trust and shared commitment," he said. "These exercises proved that our partnerships aren't just symbolic, they're operational, effective and growing stronger every day." 

The final phase took place in the rear area, where Japan's Ground Self-Defense Force Chu-SAM medium-range surface-to-air missile system was employed to defend against adversary air threats and protect critical assets. These integrated rear-area defenses are critical to ensuring freedom of maneuver and sustainment during multidomain operations.
