Russia's second Project 22350 Gorshkov-class frigate, Admiral Kasatonov, is conducting trials before commissioning, the Northern Fleet press service reported on the Ministry of Defence website. The service announced on 11 February that Admiral Kasatonov had arrived in Severomorsk following trials of its electronic warfare systems with the Northern Fleet in the Barents Sea. This included passive jamming and creating decoys to defend against missile attack.
After replenishment in Severomorsk, the frigate will test its air defence systems. The Northern Fleet said Admiral Kasatonov had already tested its Poliment-Redut air defence missile system during the first week of February against Northern Fleet Su-24 and An-26 aircraft flying at various altitudes and ranges.
