B-193 Kaluga class Soviet submarine

Submarine B-193
Project 609 “Kaluga”

Project 609 is the Soviet Navy Designation for a series of large oceanic diesel-electric submarines first designed almost directly after World War II. The first Pr. 609 hull was laid down in 1946, with the first submarine commissioned in 1948. While around 110 of these submarines were planned, just around 46 were completed and brought into service.

These submarines took in the research gained from the inspection of previous german Type XXI Submarines and incorporated them into many new technologies, such as an increased underwater endurance and a greatly improved test depth and noise level. Previously, these submarines were designed with a 23mm AA gun on the conning tower. These were later removed due to a lack of usefulness.

The Pr. 609 was used a lot for promotional soviet content and was supported as being the “start of a new era of submarines.” Examples include use on stamps, in newspaper articles and several media outlets reviewing the submarine design and effectiveness.

These submarines saw a good service life, being in active service with the Soviet Navy all the way up until 1977, where they were replaced by the Project 641 “Foxtrot” and the newer Project 641B Som “Tango” and Project 877 Paltus “Kilo” Class Diesel-Electric Submarines. Around 21 of these boats were sold off to allies in Europe, 3 were brought to museums and the rest were scrapped or kept in reserve.

Instructions
Entering the Submarine

First, climb up the conning tower and look towards the bow of the ship. You’ll find a hatch. Open it, crouch, enter the room and close it behind you. This is the airlock. There is a pump in front of you in case you are entering from underwater. If not, ignore it and open the hatch beneath you. Then, close this hatch after entering the control room. You have entered the submarine.

Moving the Submarine
To start the sub, look to the left of the helm and turn on the “Generator” key switch, then throttle up the motor and generator levers.

Diving the Submarine
First, look to the left of the engine control panel. You will see two key buttons, one that says “Fill Ballast”, the other being “Blow Ballast”. Turn on the Fill Ballast key button and then deactivate the generator. Since the submarine runs off an electric drive you do not need to turn on a separate electric motor. Then, use the keypad above the engine control panel (negative numbers only) to set your depth.

(Note, Periscope Depth is -5 metres)

Firing Torpedoes
To fire a torpedo, first come up to -5 metres, or else the torpedoes will get stuck upon firing. Go to the front end of the torpedo room, where you will find a panel with various buttons. Turn on the “Open Outer Hatch” breaker and then hold the “Fire” button shortly after. To reload, come up to -10 metres, then pump the water out of the tube by using the “Blow Torpedo Tube” key button. After the “tube water level” indicator reaches 0, go to the end of the torpedo rack and turn on the “load torpedo” key button.

Note, these torpedoes are unguided.
