4 Points You Need to Know: The Soviet Union's Kirov-class guided-missile cruisers, launched in the late 1970s, were among the largest non-aircraft carrier warships built since World War II.

-Often described as battlecruisers, these nuclear-powered ships were designed for anti-submarine and anti-ship roles, primarily armed with the P-700 Granit missiles.

-Of the original four Kirov-class vessels, only Admiral Nakhimov is undergoing modernization, while the others have been retired.

-The Admiral Nakhimov is expected to be equipped with advanced weapons like the Zicron hypersonic missile, though skepticism surrounds Russia's claims of these systems' capabilities.

Bottomline: The future operational effectiveness of this class remains uncertain.

The Soviet Union first launched its “guided-missile cruiser class in the late 1970’s. As the Cold War was heating up, both the USSR and U.S. were pumping out warships as part of an ongoing arms race.

The Soviet’s new Kirov vessels represented the largest ships - apart from aircraft carriers - to be built by any nation since the Second World War.

Based on the class’s size and weapons complement, the Kirov ships are often described as battlecruisers. The Kirov class may feature all the qualities that should make a warship formidable, but their operational effectiveness has been limited. Moscow likely only maintains its remaining Kirov ship since its naval fleet is severely lacking.

The history of the Kirov-class:

When researching the components of its future Kirov class, Soviet officials knew that the class would have to be capable of countering America’s own submarine fleet. Specifically, the USSR required that the new battleship class be capable of carrying a hefty payload of SS-N-14 anti-submarine missiles and later P-700 Granit anti-ship missiles.

Ultimately, the Granit long-range anti-ship missile system (designated by NATO as SS-N-19 Shipwreck) became the primary armament of the Kirov ships. The Shipwreck missile was developed in the 1970s to replace the USSR’s older P-70 Ametist and P-120 Malakhit missiles- which possessed short ranges.

As the U.S. Navy built up its carrier battle groups, procuring a more capable missile system was essential to the USSR. Manufacturers Chelomei/NPO Mashinostroyenia created

The Kirov class was named to honor the first of a series of four ships constructed during the Cold War. Although the Soviet Navy planned to build at least five of these battlecruisers, the collapse of the USSR stymied this goal. Kirov- the lead ship of the class- was laid down in the mid-1970’s at Leningrad’s Baltiysky Naval Shipyard.

By 1980, she was officially commissioned and was given the nickname Baltic Combatant I (BALCOM) by NATO members. Frunze was the second ship in the class to be completed, followed by Kalinin (now Admiral Nakhimov) and Yuriy (now Pyotr Veliky).

Each of these nuclear-powered vessels were designed to sport a variety of sensors, including fire control radar, air/surfaced search radar and hull-mounted sonar.

The propulsion system incorporated on these ships was derived from a combination of nuclear power and steam turbines, which enabled the ships in theory to be able to reach a top speed of 31 knots in the water.

Kirov-Class Battlecruiser Admiral Nakhimov

While the first two Kirov-class warships have been relegated to retirement, Admiral Nakhimov was selected to undergo a modernization refit in 2006. According to Russian state-run media outlets, this battlecruiser will return to service at some point, although accounts vary. Some experts believe this class of warship will never sail again. 

TASS news has indicated that the ship will rejoin the fleet, armed with the Zicron anti-ship missile and Avngard hypersonic glide vehicle. The Zicron’s alleged hypersonic speed makes it invulnerable to even the more advanced Western missile defense, including the Patriot.

Russian sources claim that the weapon can travel at Mach-8.0 (times the speed of sound). If true, this would make the Zicron the fastest missile in the world. While these specs appear great on paper, Moscow has a history of exaggerating the capabilities of its weapon systems.
