Kirov class
Kirov class is a nuclear-powered cruiser operated by Russian Navy, powered by 2 KN-3, twin of about 300 MWt each. Operating.
The only nuclear-powered surface warships built by any navy other than aircraft carriers, and the largest surface combatants afloat anywhere apart from carriers. One, Admiral Nakhimov, has been under overhaul for over a decade; the American Long Beach shows the same idea tried once and not repeated.
