this is the Uboot type VIIC by Toscio56. The original construction exploded when anything was in motion (on my device it was). I solved the explosion problem and made some profound changes.

The Unterseeboot 96 (U-96) was a German Type VIIC submarine, belonging to the Kriegsmarine that operated during World War II, or the U-96 was financed by American bombs on March 30, 1945

Controls:

Vtol: depth
Trim: periscope movement
AG1: Anti-Aircraft (AA) weapon
AG2: 88 mm gun
AG3: frontal torpedoes
AG4: rear torpedo
AG8 + Brake: opens a torpedo hatch (in the submarine tower a red flag if it is raised in the open torpedo hatch)

Modifications I made:

• totally modify the propulsion and submersion system
• modify the torpedoes
• added periscope view
• place a new version cannon
• modify as AA weapon settings
• transform the submarine from a simple Uboot to the U-96
