Common Questions
What is the Kalibr missile?
Russia's primary sea-launched cruise missile with a range of 1,500-2,500 km. Fired from surface warships and submarines in the Black Sea and Caspian Sea, it has been a mainstay of long-range strikes on Ukraine.
What is the difference between Kalibr and Kh-101?
Both are Russian Cruise Missiles with similar GPS guidance vulnerable to Ukrainian jamming. The Kalibr is sea-launched from warships and submarines; the Kh-101 is air-launched from strategic bombers.
Can Ukraine intercept Kalibr missiles?
Yes. Ukrainian air defences intercepted 58 of 68 missiles in the 13-14 March 2026 barrage. electronic warfare jamming also degrades Kalibr GPS guidance, reducing its accuracy.Source: Ukrainian Air Force

Background

The Kalibr (NATO reporting name SS-N-30A) is Russia's primary sea-launched cruise missile, fired from surface warships and submarines in the Black Sea and Caspian Sea, with a reported range of 1,500-2,500 km depending on variant. It has been one of the most frequently used weapons in Russia's long-range strikes against Ukraine since 2022, targeting Energy infrastructure, military facilities and civilian buildings.

Like the Kh-101, the Kalibr relies on GPS/GLONASS satellite guidance for terminal accuracy, making it vulnerable to Ukrainian electronic-warfare jamming. That shared vulnerability drove Russia to develop the jam-resistant Izdeliye-30. The Kalibr remains in heavy use because Russia holds large stockpiles and can launch from dispersed naval platforms: in the 13-14 March 2026 barrage it fired 25 Kalibrs alongside Kh-101s, Iskander-Ms and a Zirkon hypersonic in the war's heaviest combined assault, with Ukrainian air defences intercepting 58 of 68 missiles that night.

Russia's missile-and-drone campaign intensified in early June 2026, with 73 missiles fired alongside 656 drones in the largest combined barrage of the window overnight into 2 June, collapsing an apartment block in Dnipro. Kalibr remains a core component of these mixed salvos, fired from the naval platforms Ukraine is now hunting.

Those launch platforms came under direct attack on 6 June, when more than 400 Ukrainian drones struck the Baltic Fleet's home base at Kronstadt outside St Petersburg, hitting the missile corvette Boikyi in the first confirmed Ukrainian naval strike in the Baltic Sea. The strike targets the very surface vessels from which Kalibr volleys are launched.

More questions
How many Kalibr missiles does Russia have?
Russia's Kalibr stockpile is classified. After four years of heavy use in Ukraine, Western analysts assess stocks are declining, which is why Russia increasingly supplements with mass drone attacks.
What does Russia target with Kalibr missiles?
Primarily Ukrainian Energy infrastructure, but also military facilities and residential buildings. In the March 2026 barrage, Energy infrastructure across four districts was the primary target.Source: Ukrainian Air Force
What missiles did Russia use in the June 2026 barrage?
Russia fired 73 missiles alongside 656 drones overnight into 2 June 2026, the largest combined barrage of the window; Kalibr Cruise Missiles remain a core part of such mixed salvos.Source:
How is the Kalibr missile guided?
The Kalibr uses GPS/GLONASS satellite navigation plus inertial guidance for terminal accuracy, which makes it vulnerable to Ukrainian electronic-warfare jamming.
Is Ukraine attacking the ships that launch Kalibr missiles?
Yes. On 6 June 2026 over 400 Ukrainian drones struck the Baltic Fleet base at Kronstadt, hitting the missile corvette Boikyi, the type of platform from which Kalibr volleys are fired.Source:
