According to the forecasts of the developers, the Calibr-M cruise missile should increase its flight range to 4,500 km, and the weight of its warhead will be weighed down to one ton.
According to TASS, it is not reported yet when the Caliber-M will be put into service with the Russian Navy. However, its development and production have already been incorporated into the state armaments program until 2027. So, no more than in 8 years.
By the way, today “Caliber” does not reach the speed of sound, overcomes a maximum of 2500 kilometers, and its mass is about half a ton.
Recall that Caliber received its worldwide fame after the Caspian Flotilla launched it in positions of ISIL militants (banned in Russia). In addition, the missiles were launched against the terrorists - also from the Mediterranean.
