These weapons are apparently used by 55-ton Panzerhaubitze 2000 self-propelled howitzers, although French CAESAR or towed FH-70 wheeled self-propelled guns may also be used.
The first information about possible deliveries was made public in August of last year. It was then reported that the Ukrainian Armed Forces planned to send a total of 255 projectiles.
Its feature is the use of an inertial satellite guidance system. The deviation of the aiming point is stated to be about five meters. In this case, an aerial detonation, by contact or with a certain delay, is possible.
Vulcano is considered a joint creation of gunsmiths from Italy and Germany, but the main work was carried out by specialists from the Italian company Leonardo. Supplies to Ukraine are carried out by the German side, although the Bundeswehr itself should not put this type of weapons into service until 2025.
Therefore, it is not surprising that projectiles are tested in this way in a real combat situation.
