For a number of centuries, the battleship and its predecessor, the ship of the line, ruled the oceans. They were big, heavily armed, and were able to take a lot of punishment. But battleships haven't sailed on the high seas for nearly a quarter-century, since the 1992 retirement of USS Missouri (BB 63).
In fact, the only capital ship in active service (outside of aircraft carriers), the Petr Velikiy (Peter the Great), is in the Russian Navy.

Officially, Russia refers to the Kirov-class battlecruisers as "heavy nuclear-powered guided missile cruisers." But at 24,500 tons, and with a top speed of 32 knots, these ships are powerful. The Soviets started five of these vessels, and in the 1980s, completed three of them before the fall of the Soviet Union.
Those three were named Kirov, Frunze, and Kalinin. The fourth vessel under construction, Yuri Andropov, and the planned fifth, October Revolution, were placed on hold.
The ships were renamed by then-Russian President Boris Yeltsin in 1992 to Admiral Ushakov (ex-Kirov), Admiral Lazarev (ex-Frunze), Admiral Nakhimov (ex-Kalinin), Petr Yelikiy (ex-Yuri Andropov), and Admiral Kuznetsov (ex-October Revolution). The Admiral Kuznetsov was cancelled, and the name went to Russia's troubled carrier. The Petr Velikiy was eventually put into service in 1998. But during that time, the Admiral Ushakov, the Admiral Lazarev, and the Admiral Nakhimov went into "operational reserve."
So, let's get to the good stuff: the firepower. Petr Velikiy can handle any threat in the wild blue yonder (that's the sky, for those of you who don't sing the Air Force song regularly). She carries 96 SA-N-6 "Grumble" surface-to-air missiles, 20 SS-N-19 "Shipwreck" anti-ship missiles, 16 eight-round launchers for the SA-N-9 "Gauntlet" point-defense surface-to-air missile, six CADS-N-1 point-defense systems (each with eight SA-N-11 "Grison" surface-to-air missiles and two 30mm Gatling guns), a twin 130mm gun mount, and two quintuple 533mm (21-inch) torpedo tube mounts. The ship can also carry two Ka-27 "Helix" helicopters.

Russia is planning to bring at least one of the non-operational ships back into service. Currently Admiral Nakhimov is being upgraded with plans to return her to service in 2018. The Petr Velikiy would then receive a four-year modernization. Whether the Admiral Ushakov or Admiral Lazarev follow suit remains to be seen, with conflicting reports among those who follow the Russian Navy. Admiral Ushakov reportedly suffered a reactor accident in 1990 that was never repaired. Both ships are said to be in bad condition.
Technically, the United States Navy is required to be able to reactivate two of its Iowa-class battleships. USS Iowa (BB 61 ) and USS Wisconsin (BB 64) were designated as such under Section 1014 of the National Defense Authorization Act 2006. But barring a major national emergency for the United States, it looks as if the Petr Velikiy and the Admiral Nakhimov will remain the last of their kind.
