Ever been in a soviet submarine? Try U-434 in Hamburg!

Climb into the U-434 in Hamburg and explore a 1976 Soviet submarine • Germany Travel Blog Tourist is a Dirty Word

I always like museums that are interactive, where you can touch samples in the exhibit. But when the museum is a u-boat floating in the Hamburg harbor, which you can climb into AND you can touch things, not much holds me back. Although, someone should have warned me how tight it is in there. If you are frightened by cramped or small spaces, this is not the place for you. Walk over to Brücke 10, a local snack bar, to enjoy the view of the Elbe river and have a Fischbrötchen (bread roll with fresh fish).

The U-434 was originally a Soviet submarine with the pennant number B-515, built in 1976. It is almost 300 feet long and was in active service until 2001 before the submarine was sold to a private party and converted to a floating museum right by the Fischmarkt and Landungsbrücken in Hamburg.

A metal overpass leads you from the shore over to the top of the submarine onto a spiral staircase which leads into the torpedo room. It is right here where you begin to feel how cramped this space must have been, especially considering being locked in this room for up to 3 months. Right above the torpedoes are tight looking sleeping bunks and some small work spaces. In between are hundreds of pipes, cables and valves, several torpedo hulls are hanging all over the room. Our guide tells us that six of the torpedoes were always loaded and ready to go, another 24 were extra.

The only way into the next room is a round metal hole with about a three-feet diameter. You have to hold on to a metal hook on top of the hole in order to maneuver your body through it.

We are now in the officers' living quarters with a room that features a long dining table for 8-10 people. Since everything is so tight, the table doubles as an emergency operating table for wounded soldiers. The seats on the benches fold up onto the wall making space for the two onboard doctors to move around.

The room next door gives you a glimpse into the living quarters of the two doctors. A small sink, built in wardrobe and one bed. One bed for two people? The submarine was designed to have one bed for every two crew members. While one person was awake and working, the other one person could sleep, then they would switch. Or, to put it into the words of our guide, “The beds never got cold”.

The crew members could be maximum 5’4” tall and weigh 110 pounds or less. This guaranteed that the crew could move fast through the tight connectors and staircases in case of an attack. The total crew size for this Soviet submarine was 84, mainly used for espionage and hunting purposes.

The crew had to share only 2 bathrooms with a toilet and a shower in each, which means you better plan ahead to get ready before your shift starts. Each crew member was permitted to shower once a week in order to save resources, since the water used for the shower and toilets was put through an onboard desalting plant first. There is a separate tank on the submarine with potable drinking water, which was only used for drinking and cooking.

More round metal hole passages and a ladder lead you into the command center on the upper floor with countless gauges, cables and more valves.

Many of the metal cabinets around us are empty, they all contained classified electronic instruments in them, which were removed before selling the submarine. You can also sit in the original pilot chair while listening to sonar pings on hidden speakers, which makes the whole visit feel even more real.

We climb back down the ladder and pass the food storage room with enough food to last for up to 3 months and a document storage room. This room housed all the important and secret paperwork, guarded by 2 officers. One would sleep inside the document storage room on a bunk, the other one would guard the door from the outside.

A metal staircase leads up to several more crew quarters, passing the kitchen (or galley). Three cooks worked 12 hours shifts in a room not bigger than the inside of a modern day food truck.

One level lower is a long engine room, packed with three diesel engines and three electric motors. The diesel engines charged the electric motors, which in turn made for the almost silent movement of the submarine. In between are more beds for the crew to sleep close to their work-space.

I also spot a red telephone. Actually the third red telephone already, so I ask the guide if they are all connected. The explanation is simple: all black telephones are for internal communication on the submarine, all the red telephones are a direct hotline to the Kremlin in Moscow via satellite connection. I would love to know who answered a call like that, but I will never find out.

One last interesting fact as we walked towards the spiral staircase by the exit: The bottom third of the submarine was originally used as storage, but has been intentionally flooded with water since the conversion to a museum. There was nothing important to see down below and the extra water weight keeps the submarine stable, even on windy days.

But even if it is not very windy when you go to visit the U-434, please watch your head and your step. There is only minimal lighting and some very tight spaces you have to go through, but it is absolutely worth it. Be sure to get a guided tour, otherwise you will not be able to see the command center. The guided tour took us about 45 minutes and answered all our questions.
