Russia uses at least four Project 877 Halibut submarines in the Black Sea, of which it launches Kalibr missile attacks against distant targets in Ukraine. This was stated by naval experts G. Sutton and Benjamin Pittet in The Times commentary, Ukrainian Pravda reports.

According to them, missiles are launched from a depth of up to 50 meters, which makes it difficult for radars and satellites to detect their launches..

Sutton and Pittet noted that there are good reasons for such claims: there is information in open sources about the loading of Kalibr missiles and warheads on Russian submarines in naval ports..

" ), but we can see them being loaded with missiles and warheads in ports. Shortly before the invasion, we saw from open data how missiles were loaded onto the sides of submarines. Rocket downloads also continued after the invasion began,"

The experts also added that Project 877 Halibut submarines can launch Caliber missiles from torpedo tubes.. They can fly up to 2,500 kilometers and strike at the rear of Ukraine.

According to Sutton and Pittet, the Russian invaders began to use submarines more often after the sinking of the Moskva cruiser.. So, in the Russian Federation they are trying to avoid counterattacks by the Ukrainian coast guard.

In addition, Sutton said that Russian warships began to be more careful along the Ukrainian coast so as not to fall into the range of anti-ship missiles..

Earlier, the General Staff of the Armed Forces of Ukraine announced that Belarus is building up electronic warfare systems near the border with Ukraine..
