## What is Submarine 3D simulator?

Take command of a German U-boat in the most realistic submarine simulator and sink enemy ships!

The 3D submarine simulator puts you in the role of a German U-boat captain during World War II, engaging in an unrestricted submarine warfare campaign.
Target massive tankers carrying vital supplies and the destroyers that protect them. Fire torpedoes and send them to the depths!

Use a hydrophone (underwater microphone) to detect enemy ships while avoiding detection yourself.
Analyze the enemy’s course and speed to determine the best torpedo solution.
If you're spotted, tankers will start zigzagging and destroyers will charge in while dropping depth charges.
Dive deep below the sonar detection range to evade pursuit and wait out the danger.
Once you’ve escaped, line up a perfect shot and strike back with a torpedo.

* Features
- Realistic submarine controls via an intuitive operations panel
- Speed up gameplay with time compression (up to 16×)
- High-quality 3D graphics for immersive naval warfare
- Authentic torpedo targeting using T.D.C. (Torpedo Data Computer)
- Auto-save feature allows you to continue your mission anytime

* How to play
You can start the game by selecting a difficulty level on the title screen and tapping the start button.
Once the game begins, dive to periscope depth and use the hydrophone to locate enemy ships.
After detecting their direction, surface and carefully approach the convoy.
Once you’re close, dive back to periscope depth to stay hidden and continue your approach.

If the enemy is within 5 km, switch to the periscope view and input torpedo targeting data using the T.D.C.

T.D.C. has the following input fields:
- Target Bearing: The direction from your submarine to the enemy. Automatically set when the periscope is aimed.
- Target Speed: Estimate the enemy’s speed using the observation function while surfaced.
- Target Range: Measure the distance between your submarine and the target.
- Target Angle on Bow: The angle of the enemy’s heading as seen from your sub. Use the periscope zoom for accuracy.

After inputting all data, the correct gyro angle for the torpedo will be calculated.
Double-check all settings and tap the fire button to launch your torpedo.

If you sink enough tonnage based on the difficulty level, you will clear the mission.
The remaining tonnage required will be shown in the upper-left message panel after each successful hit.

### 1/5 — In Japanese

*2026-01-01*

Was able to download but then you can’t get anywhere as the language isn’t in English and then the boat doesn’t even generate. Good potential also to many ads

### 1/5 — Different language

*2025-12-19*

The language was in Japanese and I couldn’t even see the sun much less any ships to sink.

### 1/5 — Terrible waste

*2025-05-25*

Can’t read font. Bad color selection and just immature design.

### 3/5 — Too many adds, period.

*2025-05-23*

Great little game. Would love to keep it, but just too many adds. Uninstalled.

### 1/5 — Lost potential

*2025-01-10*

The manual is horrible, nothing on how to aim torpedos , maybe if you already know how to set gyro angles on ww 2 torpedos you will know how to set the, up to send them off. I tried guessing, it didn’t go well, I figured out how to steer the boat more or less. Can’t find anything on using the fish though and I’m not up to date on sending them to hit moving ships from a moving boat. I was excited to download , I thought I found a sim exactly like I wanted , so sad. Disappointed and not worth wasting time on without being able to use torpedoes.

### 1/5 — Boring

*2024-03-26*

There’s nothing to do

### 5/5 — One of the best

*2023-07-15*

This is a really good game, but I will say that it needs sounds and that it can have the option to have English writing in the periscope
