“She sailed to the Black Sea from Novorossiysk naval base. The trials are held by the crew and the trial team to test the main parameters and systems, mechanisms and equipment. The warship is scheduled to join the Navy later this year,”
The first stage of trials will test life-support, power and survivability systems, radar arms, communications, ventilation and air conditioning, as well as speed, maneuverability and stability. The crew has trained mooring operations, maintenance of onboard systems, and operation of mechanisms.
The next stage of trials will prepare the corvette for acceptance tests.
The Sergey Kotov was laid on May 8, 2016. The Novorossiysk naval base already operates three project 22160 corvettes — the Vasily Bykov, the Dmitry Rogachev, and the Pavel Derzhavin.
Naval News comments:
The building rate for the class is rather slow. The Sergey Kotov was laid down on May 8, 2016 and launched in January 2021.
The Project 22160 corvettes feature modular design. At the Interpolitex 2015 defense show, a scale model of the ship with two aft-mounted four-cell containers with erectable launchers of the Kalibr (NATO reporting name: SS-N-27 Sizzler) missiles was showcased.
In 2015, it was reported that the Project 22160 corvettes would be armed with the Kalibr missile system.
The Project 22160 corvette is 94 m long, 14 m wide, and has a draught of 3.4 m for a displacement of about 1,600 tons. It produces a full speed of 27 kt, a cruise range of 4,500 nm, and an endurance of 30 days. The ship is powered with a 16,000-kW main engine.
