The Czech company LLP Holding, which specializes in advanced security and defence technologies, presented its new JWI-4000 UAV interceptor at the DSEI arms fair in London.
The JWI-4000 UAV system has foldable wings and is also capable of an almost vertical take-off with an optional booster. With a climb rate of 50 meters per second, the interceptor can reach an altitude of up to 4,000 meters.
It can cover a distance of up to 70 kilometers at a maximum altitude of up to 200 km/h. The maximum achievable speed is 300 km/h. The JWI-4000’s performance spectrum is therefore within the parameters required to intercept a wide range of reconnaissance and attack drones commonly used today.

LLP did not provide any information on the size and weight of the JWI-4000. According to a model at the DSEI in London, the wingspan could be around one meter and the length around 1.5 meters.
A series of advanced sensors, supplemented by artificial intelligence, enable the autonomous interception of target UAVs, which means that the JWI-4000 cannot be interfered with, according to the manufacturer. The target UAV is destroyed by a directed fragmentation warhead weighing 1.5 kilograms.
According to LLP, JWI-4000 can use the existing sensor infrastructure of air defense networks. It is also ready for the Asterix protocol and can be integrated into special detection radars. With the Asteriy protocol is a universally structured Eurocontrol exchange of monitoring information.
The Czech LLP Holding has already deployed its autonomous attack UAV system MTS in Ukraine (-> Latest news from the war in Ukraine). It is possible that JWI-4000 will also soon be deployed in Ukraine or is already in use there.
