- Cruising speed: 50 km/h
- Maximum speed: 78 km/h
- Navigation endurance: over 2.5 hours
- Estimated range: 200 to 900 km, depending on payload
The vehicle is also equipped with a day/night optoelectronic system with a TV camera mounted at the bow, as well as an integrated GNSS receiver and communication systems. A Starlink antenna can be added for satellite remote control, similar to Ukrainian naval drones.
“This allows the drone to operate over long distances with reliable control, even in environments saturated with electronic warfare (EW),” a company representative told the portal Militarnyi.
The Fog can be operated from airborne platforms, motherships, or coastal command posts, and includes multiple redundant navigation systems to counter electronic interference.
Combining range, speed, and strike capability, Latvia’s new drone positions itself as a versatile solution for patrol, attack, and sabotage missions in modern maritime theaters.
