Russia’s Northern Fleet has successfully carried out a sea-based trial of the Kalibr missile system from the Stary Oskol diesel-electric submarine.
"The missile was launched from the underwater position at a Northern Fleet range in the Barents Sea. The costal target at the Chizha training range [in the Arkhangelsk Region in north Russia] was accurately hit," fleet spokesman Vadim Serga told TASS Friday.
On Thursday, the submarine also successfully launched a Kalibr cruise missile to hit a sea target, he added.
In late 2015, another Project 636.3 diesel-electric submarine Rostov-on-Don launched Kalibr cruise missiles from the Mediterranean Sea to destroy facilities of the Islamic State terrorist organization in Syria.
