On December 22, Vietnam’s TV channel VTV1 released a video of the first ever launch an export version of the Russian-made Kalib cruise missile by a sub of the Vietnam People’s Navy (VPN).
The export version of Kalibr, Club-S, was launched by the Project 06361 diesel electric submarine. The VPN bought 6 Project 06361 diesel electric submarines from Russia in 2014-2017. These submarines are armed with anti-ship variants of the Club S cruise missile. Some sources speculate that Vietnam has also received land attack versions of the Club S.
