The order includes the Slinger RWS, cannons, platform integration, spares, training and other supplies. EOS understands that the system is intended to strengthen defence systems in light of escalating regional conflicts in the Middle East. This sale is to an established customer country in the Middle East and the customer is a large, established defence prime contractor with several large-scale government and export contracts. The customer has requested that EOS do not disclose the customer identity due to national security considerations. The order is subject to customary terms and requires export approvals to be obtained in Australia and the United States. The systems are expected to be manufactured in Australia and delivered during 2026. This delivery program may require EOS to re-assess production schedules during 2026 and 2027. The EOS Slinger RWS is EOS’ market leading counter-drone cannon-based defence system. US ORDER (US$3m or A$5m) In recent days EOS Defense Systems USA has secured orders totalling US$3m (approx. A$5m) for integration into a counter-drone weapon system. Due to the sensitive nature of the order, the customer has requested that the final product, the customer and the end-user not be named. The customer is a large established US Defence contractor. The product will be manufactured in Australia and the order is expected to be fulfilled during 2026. CURRENT CONFLICT IN THE MIDDLE EAST During March 2026 EOS has continued discussions with several Middle Eastern governments and related representatives regarding the provisions of advanced counter-drone systems. Those systems include the established cannon-based Slinger RWS product; our High-Energy Laser Weapon APOLLO product range; and other related products for infrastructure protection. EOS views that the current military conflict may accelerate those opportunities albeit there is no guarantee that any additional orders will be secured.
