MBDA Unveils DELUGE One-Way Attack Drone: 500 km Range, 50 kg Payload
European defence group MBDA has officially unveiled the DELUGE jet-powered expendable drone system — designated a One-Way Effector (OWE) — at Eurosatory 2026. The system offers a 500 km range, 50 kg payload capacity, and a cruising speed of approximately 400 km/h. Designed to accompany long-range strike missions alongside the new LCM Mk2 cruise missile, DELUGE is intended to complicate enemy air-defence responses through saturation tactics.
Highlights
- MBDA unveiled the DELUGE One-Way Effector drone at Eurosatory 2026, with a maximum range of 500 km and a 50 kg payload capacity.
- DELUGE flies at approximately 400 km/h and is a jet-powered expendable system not designed for recovery after deployment.
- The drone is designed to operate alongside the LCM Mk2 cruise missile, generating multiple simultaneous targets to saturate enemy air-defence networks.
- The One-Way Effector concept aims to exhaust costly adversary interceptors using relatively low-cost expendable platforms, consistent with modern saturation attack doctrine.
- MBDA's dual showcase of LCM Mk2 and DELUGE at Eurosatory 2026 highlights the company's push for integrated manned missile-and-drone cooperative strike solutions.
MBDA Unveils DELUGE One-Way Attack Drone: 500 km Range, 50 kg Payload
European defence group MBDA has formally unveiled its jet-powered expendable drone system — DELUGE (One-Way Effector, OWE) — at Eurosatory 2026, presenting it alongside the newly announced LCM Mk2 cruise missile.
Key Technical Specifications
According to official MBDA data, DELUGE delivers the following performance parameters:
- Maximum range: 500 km
- Maximum payload: 50 kg
- Cruising speed: approximately 400 km/h
Tactical Design Concept
DELUGE is designed to fly alongside cruise missiles such as the LCM Mk2, serving as a complementary platform for long-range strike packages. Its core tactical value lies in generating additional targets for enemy air-defence networks — forcing adversaries to simultaneously engage multiple threat types within a compressed timeframe, significantly increasing the burden on interceptor assets and command decision-making.
The One-Way Effector concept has attracted growing interest across European and U.S. military circles in recent years. By definition, OWEs are expendable attack drones not intended for recovery. Their strategic logic mirrors that of modern saturation attack doctrine: deploy relatively low-cost systems to exhaust the high-value interceptor inventory of adversary air-defence batteries.
Exhibition Context
Eurosatory is one of the world's largest land and airborne defence exhibitions. MBDA's simultaneous showcase of the LCM Mk2 and DELUGE signals the group's active push toward integrated manned missile-and-drone cooperative strike solutions.
