At the London defense and security industry exhibition DSEI 2025 (Defence & Security Equipment International), scheduled for 9–12 September at the ExCeL Centre, Turkish company Aselsan showcased the next-generation mobile counter-drone system Korkut 100/25 SB mounted on the chassis of Nurol Makina’s Ejder Yalçın 4×4 armored wheeled vehicle.

As the manufacturer emphasizes, the new system represents a significant milestone in short-range air defense, redefining tactical protection against drones through an integrated, mission-ready design.
The Korkut 100/25 SB was developed to counter the rapidly growing threat posed by mini and micro unmanned aerial systems, combining soft-kill and hard-kill capabilities on a mobile platform. Its primary armament is a 25-mm KBA automatic cannon supplied with Aselsan-developed programmable 25×137 mm HEI-AB (High-Explosive Incendiary with Airburst) “ATOM Airburst” rounds, which can be used to neutralize both single drones and coordinated swarms, providing maximum lethality and operational flexibility.
The cannon’s theoretical rate of fire is 600 rounds/min, with a muzzle velocity of about 1,100 m/s. The ammunition load is 200 rounds. These parameters enable engagements of aerial targets at roughly 1,200 m and, additionally, ground targets at about 1,500 m. Secondary armament includes a coaxial 7.62 mm machine gun for self-defense.
The system integrates AESA radar sensors and electro-optical sensors, enabling real-time detection, automatic tracking, and engagement. Supported by machine-learning (artificial intelligence) algorithms and advanced fire-control software, the Korkut 100/25 SB delivers precise intercepts of fast, highly maneuverable low-altitude UASs, even while in motion. Its stabilized, remotely operated turret, fitted with high-resolution daylight and thermal cameras and a laser rangefinder, ensures effectiveness in all operational environments. The gun’s elevation range is from −20° to +70°.
Additionally, it is possible to counter the drone threat using a radio-frequency (RF) jammer to disrupt hostile systems’ communications or navigation links (this will not work against drones guided via fiber-optic cable — ed.).
“The unveiling of KORKUT 100/25 SB at DSEI marks a major milestone for ASELSAN and the future of close-range air defense. With its next-generation design, high mobility, and integrated counter-UAV capabilities, the system sets a new standard for tactical drone defense on the modern battlefield,” said Ahmet Akyol, ASELSAN President & CEO and added: “As we celebrate our 50th anniversary, we are proud to present this mission-ready system to our international partners, reaffirming ASELSAN’s commitment to delivering innovative, high-performance solutions that ensure operational superiority.”
It’s worth noting that the Korkut 100/25 SB actually made its world premiere earlier this year at the 17th International Defence Industry Fair (IDEF 2025) in Istanbul (July 22–27), where it was presented alongside the Korkut 130/25 SB variant, also 25 mm caliber, mounted on a two-axle trailer that can be towed by another vehicle, providing additional combat capabilities.
