Last December, while submerged, the Rostov-on-Don fired Kalibr cruise missiles in the Mediterranean Sea, destroying two Daesh targets in Syria.
"These [submarines] are the quietest subs in the world. NATO has named these Russian subs 'Black Hole.' They are diesel electric powered and fire Tomahawk-style rockets from the sea," the article read.
The Rostov-on-Don sub can remain submerged for 45 days. It has a weight of only 4,000 tons. It is very small and very fast, capable of cruising at an underwater speed of up to 20 knots.
"Because of its small size, it is able to get into shallow water. Because it is so quiet, it leaves no sound signature. It becomes invisible," the article read.
"The game plan is to challenge and confront NATO and the West," the article concluded.
