The Leleka-100 is a Ukrainian fixed-wing ISR unmanned aerial system from DeViRo used for day/night reconnaissance, target detection, and artillery fire correction. DeViRo's current Leleka line emphasizes two jamming-resistant channels, GPS-denied operation, and a modernized M2R model with longer reach and anti-interceptor-drone evasion features documented during the 2014 Russia-Ukraine War.
Ukrainian 44th Artillery Brigade crews used modernized Leleka-100 UAVs in the 2014 Russia-Ukraine War for reconnaissance, target detection, and real-time artillery fire correction; 2026 reporting also documents Snich/M2R anti-interceptor adaptations and remote-control upgrades.
Role detailsLeleka's public modernization story is mostly about survivability in the 2014 Russia-Ukraine War: jamming-resistant links, GPS-denied operation, stronger wind performance, remote-control options, and defenses against interceptor drones. Public sources identify M2 and M2R modernization labels, but do not publish a full block-by-block designation list.
| Configuration | Publicly described change | Operational relevance |
|---|---|---|
| Leleka-100M2 | Day/night optics, two independent communications channels, electronic-warfare resistance, and GPS-denied operation. | Supports reconnaissance and artillery fire correction under jamming pressure. |
| Leleka-100M2R | Reported range increase beyond 100 km and integrated enemy-interceptor-drone evasion. | Responds to Russian interceptor-drone and air-defense pressure on reconnaissance UAVs. |
| Snich-equipped aircraft | Reported evasion system demonstrated on a Leleka-100 surviving multiple FPV-interceptor attacks. | Shows survivability-focused adaptation for frontline reconnaissance missions. |
The Leleka-100 page benefits from reading the aircraft as a fielded reconnaissance system rather than only as an airframe. DeViRo describes the current Leleka set as a UAV, remote-control ground station, and additional equipment used for reconnaissance, target detection, fire correction, and objective assessment.
| Element | Reader context | Documented role |
|---|---|---|
| Air vehicle | Reusable fixed-wing reconnaissance UAV | Day/night ISR, target detection, and artillery fire correction. |
| Ground station | Remote-control station and antenna/support equipment | Mission control, data handling, and launch-team support. |
| Payloads | Day camera and thermal night camera | Reconnaissance and observation in daytime and night conditions. |
DeViRo presents Bulava as a strike-and-reconnaissance system that carries forward combat-proven Leleka reconnaissance experience into a loitering-munition workflow.
| Compatible item | Item type | Compatibility evidence |
