The Russian Navy’s Kazan nuclear submarine nearly completed state trials with the launch of Oniks anti-ship cruise missile in White Sea.

“Today, the lead ship of the Yasen-M project, Kazan, has successfully fired an Oniks anti-ship cruise missile at a sea target. It was carried out as part of the next stage of state tests and took place in the afternoon from the White Sea. The naval target position was successfully hit by the warhead of the Oniks missile,” the Russian Ministry of Defense announced Monday.

The vessel entered the final trial stage with its regular crew and commissioning team onboard on November 21. After the completion of the state tests, Kazan will be admitted to the Russian Navy.

The crew will practice surface and underwater maneuvering at various depths, and will check the ship’s main systems, including weapons.

During the tests, the Project 885M Yasen-M Kazan submarine launched a Kalibr cruise missile that hit its target over 1000km away.

This class of boats are built by St. Petersburg-based Malakhit Marine Engineering Bureau. Based on the Akula-class and Alfa-class, it is projected to replace Russia’s Soviet-era nuclear attack submarines. They are armed with Kalibr and Oniks cruise missiles, and will eventually carry Tsirkon hypersonic missiles as their basic weapons.
