«Ursa Major» is a declaration of independence. A ballast repair system and an additional engine will help to cope with threats, and with a spacious hold, a shuttle and a drone, you can forget about shipyards for weeks.

Yes, she's not as nimble as her younger sister, and not as toothy as combat submarines. But she is our home. The «Big Dipper» in the darkest sea. Thousands of tons of steel, supplies, and hope. She doesn't run away from danger. She's going through it.

⸻ All signs and buttons in the interfaces on the entire submarine have been translated. The translation changes automatically depending on the language you are using.

A guide that can help you create a multilingual submarine:

⸻ Want to learn more about submarines and take part in their creation? Visit Boosty! ⸻ 1) Manual control of the doors. (the doors stop closing on their own) 2) Permission/prohibition to dock/undock for the shuttle. 3) Activation of the main batteries. (Activation of the spare batteries is carried out in the reactor compartment.) ⸻ Modular repair system: 1) The activation button. 2) Selecting a repair compartment. Trigger the detonator: - In the reactor compartment, the detonator only repairs the compartment itself; - In the ballast compartments, the ballast entry hatch automatically opens before the detonator is triggered, allowing both the ballast compartment and the compartment above it to be repaired.

After the detonator is triggered, the green light next to the compartment symbol turns off. This signals the captain that the detonator is not ready.

Go directly to the detonator, replace the foam grenade, and press the button next to the detonator. A green light will turn on above the detonator and in the control room, indicating that the detonator is ready for use again. ⸻ An example of how the modular ballast compartment repair system works. ⸻ Ballast compartments with manual water discharge in case of contamination. ⸻ Activation/deactivation buttons for controlling the upper and lower docking hatches. ⸻ The manual depth charge drop system outside the navigation terminal, equipped with a safety device, is activated using a button or camera. ⸻ Locks designed to protect against creatures that can open doors. ⸻ The approximate range of the discharge coils and the location of the depth charge launcher. ⸻ Example of the «moon pool» operation.
