Wild Hornets Sting S

History

The Wild Hornets Sting S is a Ukrainian high-speed interceptor UAV developed to destroy jet-powered unmanned aircraft and other hostile aerial targets. It is a further development of the original Sting interceptor created by Wild Hornets for counter-UAV operations.

The Sting S uses a quadcopter configuration and is undergoing active combat trials in Ukraine. Its development focuses on engaging faster jet-powered threats that place greater demands on interceptor speed, control, and terminal guidance than conventional propeller-driven attack drones.

During combat testing in 2026, Sting S interceptors destroyed approximately ten Geran-4 jet-powered UAVs and several Geran-5 small cruise missiles. Wild Hornets has not disclosed the final tactical and technical characteristics because the design is still being refined before planned mass production.

Development

The Sting S evolved from the earlier Sting interceptor developed by Wild Hornets. The original Sting program was created to provide a relatively inexpensive means of intercepting hostile unmanned aircraft, particularly Shahed- and Geran-family attack drones. The earlier Sting uses an FPV-controlled quadcopter layout and established the basic operational concept from which the Sting S was developed.

The Sting S was adapted specifically for the interception of jet-powered unmanned aircraft. Its final configuration remained subject to adjustment during combat trials in September 2026, with changes expected to reflect experience gained during operational use.

Combat trials

By September 2026, the Sting S had entered active combat testing. Approximately ten Geran-4 jet-powered UAVs and several Geran-5 small cruise missiles had been destroyed during these trials. A crew identified as Rubin from Ukraine's 1020th Anti-Aircraft Missile Regiment also used a Sting S to destroy a Geran-5 during the same month.

Most of the documented Sting S interceptions were conducted using the Hornet Vision Ctrl remote-control technology. Wild Hornets expects this control architecture to support rapid expansion of Sting S operations after mass production begins and the interceptor is supplied to additional combat units.

Design

The Sting S is a high-speed quadcopter interceptor. Its configuration follows the broader Sting family concept while being optimized for the interception of jet-powered aerial targets.

Control system

The interceptor can be operated through the Hornet Vision Ctrl system. During its combat-trial phase, this system was used for most of the reported Sting S engagements. The available information does not establish that Sting S operates autonomously, and its confirmed combat use has relied on remote control.

Target set

The Sting S was developed primarily to engage jet-powered unmanned aircraft. Confirmed combat-trial targets include the Geran-4 jet-powered UAV and the Geran-5, which is described as a small cruise missile rather than a conventional delta-wing Geran-type drone.

No final figures for speed, range, endurance, altitude, payload, mass, or other performance characteristics have been released for the Sting S. Specifications published for the earlier Sting interceptor should not be treated as specifications for the Sting S because the newer model is a distinct development intended for faster targets.

Program status

As of September 2026, the Sting S remained in active combat trials. Wild Hornets was continuing to refine its tactical and technical characteristics based on operational experience.

Mass production had not yet been described as underway. The developer planned to scale deployment after production begins and after additional Sting S interceptors are delivered to combat units.
