SSU hit a Russian submarine in Novorossiysk

The Security Service of Ukraine conducted another unique special operation and arranged maritime "bavovna" in the port of Novorossiysk. For the first time in history, "Sub Sea Baby" underwater drones blew up a Russian Project 636.3 "Varshavyanka" class submarine (NATO classification — Kilo). As a result of the explosion, the submarine sustained critical damage and is, in effect, disabled.

On board the submarine were four cruise missile launchers for "Kalibr" missiles, which the enemy uses for strikes on the territory of Ukraine.

This was a joint operation of the 13th Main Directorate of Military Counterintelligence of the SSU and the Navy.

The cost of a "Varshavyanka" class submarine is about 400 million US dollars. Given the introduced international sanctions, the construction of an analogous submarine may currently cost up to 500 million dollars. This class of submarines is also known by the name "Black Hole" due to the hull's ability to absorb sounds and remain stealthy to sonars.

We remind you that the blown-up boat was forced to stay in the port of Novorossiysk due to successful special operations of "Sea Baby" surface naval drones, which forced Russian ships and submarines out of the Sevastopol Bay in temporarily occupied Crimea.

There’s a mountain of differences between the Pearl Harbor battleships and this submarine. For starters just the fact that this is a submarine is a huge difference. The key component of a sub is the pressure hull. I believe US subs cast the pressure hulls as a single massive piece, so no seams that could suffer from poor welding etc. I know older Soviet subs were two pieces welded together, but I’m not sure if newer ones are one or two pieces. Whatever the case, if that explosion did significant damage to the pressure hull then it’s basically a complete write off. They might be able to salvage components from this sub, but they would have to cast a whole new pressure hull, which basically means a whole new sub.

Then there’s the more modern electronics in these subs. The kilo class subs were first launched in the 1970s, so 30+ years after Pearl Harbor. There’s bound to be a lot of computerized and other electrical gear in the sub that doesn’t take too kindly to being submerged in salt water for a prolonged period of time. There’s bound to be a lot of different metals used throughout the sub, and not just in the electronics. Put different metals in a salt bath and you get electrolysis, which corrodes the metals over time. I doubt raising that sub to the surface and drying it out will be a quick process, so there’s a lot of time for equipment to corrode beyond usefulness.
