R-31 Tachanka Mk. 1-4

Love of huamanity for repurpocsing civillian vessels came to Europe. Some Coalition oficers turned their eyes to R-29 cargo submarine and they saw big potential for modification. After some time R-31 was built and got name after ancient weapon - "Tachanka" Submarine has enforced armaments - back and front half-spheres have two guns, bow has railgun. All of this beauty controlled by former passanger deck, which was separated from cargo hold by bulkhead. Overall armament was enforced for military tasks. For fighting ballast flora "ballast blast" system was implemented that allows to ditch unwanted passenger with one click. Or you can use it to fight intruders Mk. 4 modification has most developed gun deck - from engineering deck sonar was moved here, cargo hold was sealed and separated with hatches. Also gun deck has remote control system for controlling charge speed of supercapacitators and percentage of supercapacitator charge was implemented on top of loaders. All credit for main structure and overall hard work goes to R-29's author, my shipyard only modified his submarine
