The Russian improved Kilo Class diesel electric submarine Rostov-on-Don (B-237) launched cruise missiles at targets in Syria today, from a submerged position in the eastern Mediterranean. This is the first time a Russian submarine has struck targets in Syrua since Russia began its aerial offensive around October and the first time a Kilo Class fired cruise missiles in anger.
The missiles involved were likely the 3M-14 Klub-S/Kalibr submarine-launched land attack missile, which is roughly equivalent to earlier versions of the U.S.-made BGM-109 Tomahawk land attack missile. It has a range of around 1,200 miles and packs a 1,000 pound warhead. The Russian Ministry of Defense reports that two targets near the ISIS defacto capital of Raqqa were struck with via the sub’s missile attack.
