The small missile ship "Naro-Fominsk" of Project 21631 "Buyan-M" is preparing to join the Russian Navy and is undergoing state tests. It will become the eleventh ship of Project 21631 class "river-sea", capable of guarding and protecting the economic zone of the state.
The tests included anti-aircraft missile firings. A SAB-250 illuminating aerial bomb, dropped by a Su-24 bomber of the Baltic Fleet's naval aviation, was used as an aerial target. The target was hit by "Caliber" missiles from "Gibka" anti-aircraft guns. This complex is designed to provide air defense.
"Gibka" can shoot down airplanes, helicopters, drones, cruise missiles, and high-precision weapon systems flying at low and extremely low altitudes at any time of the day and in conditions of limited visibility. They can also hit ground targets of the enemy deep from the coastline. Depending on the modification, anti-aircraft guns have from four to eight missiles. These can be "Calibers", "Onyxes", or "Iglas".
