Тhe Russian Navy is reported to have brought the two nuclear reactors powering the country’s last Kirov Class battlecruiser, the Admiral Nakhimov, back online, indicating that the warship is likely to begin sea trials in the near future. The first reactor was reported by state media to have been brought online in late December, while the second was brought online on February 2. “The consecutive physical launch of the cruiser’s two reactors demonstrates the readiness of the entire nuclear powerplant of the ship for operation in all modes,” state media outlet TASS reported. The Admiral Nakhimov is one of four Kirov Class battlecruisers built for the Soviet Navy in the 1980s, which at the time represented by far the most formidable surface combat ships in the world. Their 28,000 ton sizes place them at more than three times the size of American Arleigh Burke Class destroyers, at at over twice the size of any other surface combat ship, with comparable displacements to aircraft carriers such as the Japanese Izumo Class. As the only surface combat ships using nuclear propulsion systems, the cruisers are capable of sustaining high 32 knot speeds and powering high energy armaments and sensors for extended periods.
