Submarine Proposals SE2
Create a special nose fairing of different sizes for large submarines, reduces water resistance.
Create ballast tanks that have three automatic modes. Empty (for surfacing), neutral buoyancy (for changing depth and/or maintaining it), full (emergency dive)
Special underwater turrets with switchable spotlights that can withstand high pressure. Small-caliber autofire and Heavy (2 types).
Depth and direction rudders for stabilizing and directing the vessel without using gyroscopes.
Propellers with variable blade pitch for the ability to maintain better efficiency and reverse while maintaining one-way rotation speed.
Propellers 3-blade (Efficient) 5-blade (Less noisy and suitable for military ships) 7-blade (Less efficient but the quietest). It would be worthwhile to muffle the noise of targets near the water surface depending on the height of the waves. And the waves are dependent on the weather.
Hydrophones that can detect a target over the horizon, but provide information on the loudest noise source according to Beleng. The type of target blades. Or, instead of determining the blades, determine the speed of the target. Do not determine the distance. Hydrophones may not receive a signal if there is an obstacle, such as your own submarine. The attenuation of the noise of targets near the surface of the water depends on the height of the waves. And the waves depend on the weather. Hydrophones are more effective if not near the waves near the surface
Sonar allows you to detect a target at a shorter distance but with an accurate distance, can be narrowly focused for stealth.
At high speeds, the effectiveness of sonar and hydraphone decreases, especially the hydraphone.
High-frequency sonar, has the shortest distance, is barely noticeable, but you can see the outlines of objects, for example up to 500 meters. You can also see the bottom.
A simple directional echo sounder for measuring the depth to the bottom.
Indications in the description of the strength limit of blocks in atmospheres and indication of depth (in the future for planets with higher gravity and atmospheric pressure). Special blocks such as hatches and connectors for great depths. Heavy armor holds depth better. The thickness of the armor also affects the ultimate strength. Only the armor that is an intermediary between the water outside and the air inside the boat is taken into account, the armor that is not an intermediary holds any pressure.
A compass in the form of a gyroscope allows you to determine the direction. (The planet must have north and south for non-space navigation). Or it must be integrated into the captain's post.
A special post for the captain that automatically controls the ballasts, rudders, displays information from the hydrophone, sonar and high-frequency sonar to choose from. Indicates the current depth as well as navigation information. Two types, miniature and standard.
Light armor reduces (signature) sonar visibility. While the heavy one better protects the living compartments from pressure. (fits the concept of one and a half hull submarines quite well)
And a special combat post for drone control, which displays a 2D map, displaying your own submarine and its current data. You can also create rulers and target markers on the map and set their characteristics, as well as determine the lead to them for kamikaze drone guidance. This is no longer a serious proposal, but it should help for long-range torpedo guidance and determining the approximate distance to the target using the passive TMA (Target Motion Analysis) method. Without using active sonar. The only thing for this method is to know the true speed, for this submariners usually use a noise file of different ships in real life to determine the type of propellers and the number of revolutions per knot. Then knowing the speed, you can find out the distance. Therefore, this is a completely irrelevant proposal. But the drone control post by wire for reconnaissance and destruction of targets with a warhead can also be an ordinary pilot's seat. Although navigation would be useful.
I think there is no need to suggest a thermal layer of water, but I will tell you an idea. Depending on the time of day, water heats up differently depending on the depth. Therefore, at a certain depth, the direction of sound propagation changes. What is below the thermal layer is difficult to hear, and vice versa, for those who are below it, they can hardly hear what is above it. The propagation of sonar sounds is also distorted and detection at a greater distance is less effective.
I like this feedback
I did not have time to write more.
A special wire for transmitting energy, information and control. So that it would be possible to charge batteries without docking. So that it would be possible to control kamikaze drones at a distance underwater without radio communication jammed underwater. So that it would be possible to conduct reconnaissance with a submarine drone or a towed sonar for submarines and ships.
The batteries are silent, the reactor is low-noise, hydrogen generators are very noisy. But the generators can charge the batteries and have an essentially unlimited source of fuel in the water. And uranium should be added at great depths as an ore, so that it would be possible to use nuclear energy on the planet.
Underwater animals that create different noises. Some of them are deep-sea aggressive creatures and will attack the submarine and underwater base if they are too noisy. Sonar scares away the smallest of them because the sound is painful and can lead to injuries. But on the contrary, it can attract the largest and most dangerous ones.

If the target is on the bottom or very close to it, then it is more difficult for an active sonar to detect it.
Addition of a radar and a direction finder capable of detecting radar radiation from a distance twice as great as the radar itself detects with radiation. The radar has a narrow-beam detection function. The radar is less effective in range than the sonar.
Creating a block with a log of the time and direction of detection by the direction finder. With the function of activating other blocks. So that the player offline could have an idea of the situation in the area. For example, solar panels go underwater or into a mine for a certain time. If the player for some reason does not use or there is not enough safe zone.
