Drones and how to kill them?

Turkey going all-out with its anti-drone systems; new development

"ASELSAN SEDA 100-cUAV is an advanced acoustic drone detection system specifically designed to identify and track UAVs (unmanned aerial vehicles) using sound-based technology. By leveraging sophisticated acoustic sensors, the system can detect and pinpoint drones in real time, even in challenging environments where conventional radar or visual systems may struggle.

Key features:
  • Wide detection range: Capable of covering large areas to detect drone activity with high accuracy.
  • All-weather performance: Operates effectively in various environmental conditions, including low visibility or noisy surroundings.
  • Rapid response: Provides instant alerts and precise tracking information to enhance counter-UAV measures.
  • Low-power consumption: Designed for efficiency, it can be deployed in stationary or mobile configurations for flexible use.
  • Multi-sensor fusion: Integrates acoustic data with inputs from multiple sensors, significantly improving detection accuracy, minimizing false alarms, and providing more reliable tracking information. "

Interesting choice of caliber, getting to be the smallest practical airburst/PFFF caliber.

"While developing the land-based 25 mm weapon system, which included the 25×137 mm Atom airburst round, Aselsan engineers had the idea to exploit the new ammunition in the Counter-UAS role, to kill unmanned air systems at range. “We considered weight, in order to be capable to install the Korkut 25 n a wide variety of vehicles, as well as cost,” an Aselsan representative explained to EDR On-Line.

The system lethality is given by a chain that starts with the target detection and ends with its neutralisation, the key element for the latter being the ammunition. The Atom 25 mm round is a pre-fragmented projectile filled with high explosive. From the rear to the front we find the power source, the base fuse with its electronics, the booster and finally the pre-fragmented body. The latter was the subject of deep studies in terms of materiel and pre-fragmentation in order to generate the appropriate cloud of fragments to cause maximum damage to the target, usually a Class 1 drone. While the 35 mm round used on the Korkut is filled with tungsten cylinders, the room available in the 25 mm did not allowed such a solution hence the decision to go for a pre-frag HE ammunition

The 25 mm gun muzzle is fitted with a muzzle brake that includes coils tat allow measuring the velocity of the single round, data being fed into the programming system which generates a current into the last magnetic coil, which programmes the smart fuse by induction before the round leaves the gun. The programming is done on the base of data provided by the tracking system, which determinates the point where the round must be ignited to generate the cloud of fragments, usually a 10-round burst being fired to ensure maximum kill probability. The Korkut 25 turret hosts 200 rounds therefore a single system can carry out 20 engagements before needing to be reloaded."

More .militarys getting on board the Swiss & PLA AHEAD, gun based, counter missile- munitions bandwagon.

AHEAD-style is one of the simpler ways to do an electronically timed fuze. Plus, it gives you the exact MV for that projectile to give you best bursting time.

Turkey is developing layered defence against drones with it's line of airburst munition,

They were also working on a 20mm calibre with programmable airburst, not sure if they abandoned it in favour of the 25mm.
