Exploding Swiss Ammo Splits Into Four Effectors to Counter Drones

SHATTER4K projectile splits into four self-destructing effectors mid-flight, increasing hit probability against fast-moving drones while limiting collateral damage.

A Swiss firm is stepping into counter-drone warfare with its own take on explosive bullets, introducing a multi-effect concept compatible with 7.62mm and 5.56mm cartridges.

Thun-based SwissP Defence unveiled SHATTER4K, a self-destructing projectile that splits into four effectors after leaving the barrel.

It flies toward its target at a slight angle, reportedly boosting the chance of hitting fast-moving drones.

SHATTER4K works with standard service rifles and machine guns with no modifications needed.

Unlike similar systems on the market, the company said its counter-drone bullets reduce barrel wear and limit collateral damage.

“Our philosophy is to offer effective solutions, not experimental concepts,” SwissP chief executive officer said. “Accidental damage is reduced and the probability of hitting the target is increased.”

‘Precise Imprecision’

SwissP Defence engineered the projectile to split its effectors strategically, describing it as “precise imprecision.”

“We wanted to achieve predictable and reproducible dispersion of the ammunition in order to increase the probability of hitting fast-moving targets such as drones,” the company’s development head stated.

The official added that the design also ensures the smallest possible and most predictable ballistic footprint, maintaining effectiveness while limiting off-target effects.

The counter-drone ammo was presented during the EnforceTac 2026 event in Nuremberg.
