Shchuka-B MM (Akula)

Shchuka-B MM (Small Modernized)

A submarine based on project 971 (Akula).

Shchuka-B (Project 971) -

The Akula class, Soviet designation Project 971 Shchuka-B (Russian: Щука-Б, lit. 'pike', NATO reporting name Akula) are a series of nuclear-powered attack submarines (SSNs) first deployed by the Soviet Navy in 1986. There are four sub-classes or flights of Shchuka-B, consisting of the original seven Project 971 boats (codenamed Akula I), commissioned between 1984 and 1990; six Project 971Is (Improved Akulas), commissioned between 1991 and 2009; one Project 971U (Akula II), commissioned in 1995; and one Project 971M (Akula III), commissioned in 2001. The Russians call all of the submarines Shchuka-B, regardless of modifications.
Some confusion may exist as the name Akula (Russian: Акула, meaning "shark" in Russian) was used by the Soviets for a different class of submarines, the Project 941, which is known in the West as the Typhoon class. The Project 971 was named Shchuka-B by the Soviets but given the designation Akula by the West after the name of the lead ship, K-284.
According to defense analyst Norman Polmar, the launch of the first submarine in 1985, "shook everyone [in the West] up", as Western intelligence agencies had not expected the Soviet Union to produce such a boat for another ten years.

Design

The Akula incorporates a double hull system composed of an inner pressure hull and an outer "light" hull. This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs.
The distinctive "bulb" or "can" located on top of the Akula's rudder houses its towed sonar array, when retracted. Most Akulas have the wake detection system (Russian: Система обнаружения кильватерного следа) (SOKS) hydrodynamic sensors, which detect changes in temperature and salinity. They are located on the leading edge of the sail, on the outer hull casing in front of the sail and on the bottom of the hull forward of the sail.
Akulas (excluding Nerpa) are armed with four 533 mm torpedo tubes which can use Type 53 torpedoes or the RPK-2, RPK-6 missile, and four 650 mm torpedo tubes which can use Type 65 torpedoes or the RPK-7 missile. These torpedo tubes are arranged in two rows of four tubes each. The external tubes are mounted outside the pressure hull in one row, above the torpedo tubes, and can only be reloaded in port or with the assistance of a submarine tender. The 650 mm tubes can be fitted with liners to use the 533 mm weaponry. The submarine is also able to use its torpedo tubes to deploy naval mines. The modernized versions, like Vepr, will be equipped with the Kalibr cruise missiles.

ГАС (Hydro Acoustic Station):
Two large sonars in the nose (+ Active search for 1 sonar)
One large sonar in the stern
One Hydro Emitter horizontal
One Hydro Emitter vertical

Nuclear reactor: 3 infinite generators for 4 kilowatts

Navigation:
Two auto-scrollers
Autopilot
depth Hold
Stabilizer

Communication:
Secret Encryption machine (connected directly to the antenna)
Shortwave radio Station
Morse Station
Video Station
Radio Direction Finder
Locator beacons
One Radar

Rescue system:
Special pop-up capsule (attention! - the capsule floats slowly so that the crew does not get caisson disease) - the capsule can withstand a pressure of 100 atmospheres (the capsule contains an emergency beacon)
Emergency surface system
In the torpedo and reactor compartments there is an emergency docking hatch
The torpedo tube contains rescue suits - ИДА-59

Notice:
Before starting the campaign, wait for the reactor to fully warm up. Then turn on the main turbine control and slowly pull the handle.
Also-raise the radar mast before using the radar!

Diving:
Close all hatches, fill up all ballast (neutral ballast is configured) and dive

Surface:
Blow all the ballast and float up

Depth Hold:
Set the depth (positive only) to "Set Depth"
then click on the "Auto Depth" button

Encryption Machine:

Receiving:
to start, set the codes:
(disabled = 1)
Code 1: 1
Code 2: 4
Code 3: 8
(For example, take code 148)
Attention! The code on the receiving and transmitting sides must be the same!
Then set the frequency at which we want to receive
And we start receiving the message:
the encrypted code will appear on the screen and the letter that was encrypted will appear below

Transmission:
Set the same code (148) and set the frequency
Then click on the "Transmit" button
And start transmitting:
there is a keyboard Below
Click on the letter you want to pass (you need to hold it for a short time)
Just above you will see the number of the letter you are passing

Torpedoes:

Launch:
In "Bearing", set the course you want to aim the torpedo at, or you can switch the bearing to the compass sensor and roughly aim the torpedo at the target
Use the "W-S" buttons to set the depth of the torpedoes
On the "A-D" buttons, you set the pre-emption on which the target is moving
Then open the front covers of the torpedo tubes (this can be done from the torpedo control station - hold the "Open/Close Torpedo Tubes" button
Torpedoes are ready!
There are torpedo launch levers to the left of the seat
Torpedoes in the water! They follow a given course and depth in search of a target
Then close the front covers with the "Open/Close Torpedo Tubes" button (push)
And done
Torpedo tubes can be reloaded!
