I played the scenario with v1.14. The Udaloy and his 2 helicopters are formidable opponents but not invincible.
The Udaloy also has SS-N-15 which drops torpedoes to 22nm. So even without helicopters avoid dragging in the area. elsewhere, some of you have hit you, that's why you did not see it coming.
Regarding the sensors, its hull sonar (active and passive) has a range of 16nm and allows it to monitor above the layer and has a blind spot of 90 ° to the rear.
Its towed arrays (passive) and VDS (active) have a range of 8nm and monitor below the layer over 360 °.
If the boat goes too fast and cavits (sup 8 or 13kts), the hull sonar's abilities are degraded.
To make simple an active sonar "sees you" (making noise) even if you do not make noise, and passive sonar, "hear you" when you make noise. Imagine that you are out in the dark and that you are looking for someone who is so hiding, you have with you a flashlight (your active sonar). You have the choice be you turn on your flashlight (your active sonar) and you go may be seeing him but he too will see you. Or you make no noise and you listen (your passive sonar), but if it makes no noise you do not hear it. Obviously if you walk or run, the sound of your footsteps will hide the sound of his footsteps.
You can detect active sonar but not passive sonar.
By default in Command, when you create a patrol mission; the radar is active.
So before entering the area goes up to periscope depth to try to capture its radar emission. You can also use the convergence areas to find a ship.
Also think about turning off the radar in mission doctrine if you create a Patrol mission. Otherwise it will automatically activate at periscope depth.
The MK48 is a torpedo that can reach 27nm if you modify "Kinetic range for torpedoes" in the doctrine.
It is wire-guided, once it has left the submarine you can fly it like a submarine. Its range will depend on its speed 27nm at 50kt or 20nm at 65kt.
You can make it travel in or under layer to avoid detection.
Since v1.14, when you guide a torpedo your speed is clamped to 10kt until your torpedo disappears (by destruction or over fuel, about 32 minutes for an MK 48) or if you are under attack weapon.
Impossible to shoot in the axis and to spin full gas, it is necessary to wait for the disappearance of your torpedo to exceed 10kt.
Then, if your torpedo is detected, Command creates a "probable sub contact"
in the direction from which the torpedo comes. The helicopter will investigate the area of "probable sub contact" .It is therefore thought to bring your torpedo from a different direction than your submarine.
In Command, you do not hear the helicopters flying, you detect the sonar sources of their active sonar dipping (HF sonar) when they are hovering. The operation lasts about 4 minutes, then it changes position if you are detected, it will approach you until you identify and attack you.
The helicopter can detect you by flying over you with a magnetic anomaly detector (MAD) with a horizontal range of 1nm but a vertical range of over 2500ft.
The helicopters drop buoys, active and passive (according to their ASW loading). You can detect active buoys but not passive ones. A buoy that detects you is returning your position to a helicopter or a plane that is patrolling near the buoy. If the helicopter or airplane is too far away or is not in the air, you will not be detected.
A helicopter has 1 or 2 torpedoes max, after their shooting, the helicopter returns to refuel, the operation lasts 30min (if the option "Quick turnaround" has been activated) or 4 hours.
When a helicopter is in the air and you destroy the boat that serves as a base. The Helico looks for a new base. Depending on his distance, he may abandon his mission and try to join his new base. If there is no base available, he will continue his mission until the breakdown of fuel ... .
I'm going to stop there because I'm running out of fuel too. Try to play the scenario from the editor to see your mistakes and when you are detected.
Do not hesitate to correct me or to complete me.
Good hunt !
