According to Russia's "Information Daily", in view of the increasingly frequent activities of NATO ships in the Black Sea and the Arctic, which poses a serious threat to Russia's national security, the Russian Navy's Black Sea fleet and the shore defense missile brigade of the Northern Fleet will be equipped with new shore defense missile systems to improve the control ability of most sea areas in the Black Sea and Barents Sea. According to sources from the Russian Ministry of defense, the Russian Black Sea Fleet's coastal missile brigade in Crimea and a coastal missile brigade of the Northern Fleet will receive an improved "ball" coastal missile system that can carry kh-35 anti-ship missiles. The original range of kh-35 anti-ship missile is no more than 200 km, and the improved range is increased to more than 300 km. It adopts a new guidance system, and the strike accuracy is greatly improved. Dmitry bortenkov, a Russian military expert, pointed out that the current situation in the Black Sea region is tense, and strengthening defense in the Crimea region is an important task for Russia. Recently, the US command ship "Whitney hill" and the destroyer "Porter" successively sailed into the waters of the Black Sea; NATO drones and reconnaissance aircraft frequently carry out reconnaissance activities near the Russian border. In this case, the replacement of the improved "ball" shore defense missile system can expand the enemy's restricted area and improve the reliability and effectiveness of shore defense. Since the beginning of this year, the Russian Navy's shore defense missile force is actively improving the operational methods and tactics of the shore defense missile system. During a series of military exercises held this year, the "ball" and "bastion" shore defense missile systems worked closely with warships and UAVs to carry out combat missions. During the exercise, the UAV searched for the position of the hypothetical enemy ship formation and sent coordinate information to the shore defense missile system to ensure the accuracy of the shore defense missile attack. At present, the Russian navy is actively carrying out exercises to defend military bases by using the shore defense missile system. At the end of November, the coastal defense forces of Russia's Black Sea Fleet held a "dance" and "bastion" coastal defense missile system launch exercise. The exercise subjects included implementing missile attack operation procedures on hypothetical enemy warships, changing launch positions and launching attacks again. In addition, the Russian navy is studying the establishment of a strong coastal defense system in the corresponding strategic direction. Not long ago, the Russian Baltic Fleet held a "dance" and "bastion" rapid deployment exercise of shore defense missile system. In the process, the missile troops of the Baltic Fleet carried the "ball" and "bastion" shore defense missile system, and maneuvered from the Baltic Sea to Murmansk and alhangersk states. They acted jointly with the Northern Fleet to repel the imaginary enemy who launched an attack from the waters of the Barents Sea. The training shows that the Russian Navy's coastal missile defense forces are fully capable of rapid deployment. (outlook new era)
