The THUNDERBOLT 40/70 T Naval Gun System is a next-generation dual-barrel weapon engineered by ERMAKSAN’s Defense Division to meet the evolving demands of naval warfare. Its twin 40 mm barrels deliver continuous, mission-assured firepower, with built-in redundancy that maximizes reliability under all conditions.

The stealth-optimized composite cupola minimizes radar cross-section, enhancing survivability and reducing detectability. With a 736-round maximum capacity and a firing rate of 2 × 300 rounds per minute, THUNDERBOLT delivers sustained fire support and decisive lethality. 

Fully interoperable with shipborne radars and Combat Management Systems (CMS), it enables precision engagement across multiple domains. By combining high firepower, advanced integration, and cost-effective lifecycle design, the THUNDERBOLT 40/70 T empowers naval forces to defend national waters, secure strategic sea lines, and provide reliable multi-role fire support in both littoral and open-sea operations.
