USS WALLEYE SSN-579

USS Walleye is the lead boat of the Walleye class, a fast and small class of nuclear attack submarines. Walleye was designed in 1953 with the intention of making a small nuclear submarine, without losing the comforts and advantages of larger nuclear boats. However, many would say that the only thing they succeeded at was the first part.

After seatrials, it was quickly concluded by the crew and engineering staff that the Walleye was unreliable, unsafe, and lacking in general. This is why only 2 submarines of this class were constructed and both were decommissioned and quickly scrapped in the 1960s.

Walleye comes with the following equipment:
1x S3W-M reactor
2x HP boilers
4x HP turbines
2x CM condensers
2x Accumulator batteries
2x 1.5MW generators
1x ACS automatic diving and heading hold system
1x AN/BPS-12 naval radar
1xAN/BQR-4b passive sonar
1x QLA F-N active sonar
1x UME-2 ESM system
1x HSA location finder
1x HSA echo locater
4x MRN torpedo launchers
8x MKI MRN torpedoes


This submarine comes with a variety of different systems which each require some instruction before using.

NOTICE
Make sure to read this part before using any of the systems:
-If the temperature is above 25 degrees, some equipment may NOT work. To counter this you must turn on the onboard AC unit by opening the AC coolant valve located in the control room, and turning on the airconditioning in the torpedo room, control room, maneuvering room, and the electric spaces. If you do not do this, the following equipment will not work: active&passive sonar, ESM detector, radar system, weapon systems, hydraulic pumps, and the air compressor.
-The submarine is only able to sustain fast speeds (Steam valve 0.8, throttle 3+) for a little less than 15 minutes (900 seconds). If you maintain a fast speed for longer than 15 minutes the clutch will break down and limit your speed. To repair the clutch you need to set the throttle to 0, completely close the steam valve, and fix the clutches using the 'FIX CLUTCH" button located behind the hatches under the aft control planes.

BEFORE STARTING
When entering the submarine, make sure to:
-Enable a battery
-Turn on all breakers
-Turn on one of the hydraulics pumps and their coolant
-Make sure to turn the AC unit on if the temperature is above 25 degrees


NUCLEAR REACTOR
-Head to the maneuvering section (Behind the control room)
-Turn both secondary, both main, and both condenser pumps on
-Set a temperature of about 140
-Open the steam valve to your desire
-Wait for the boiler to warm up

DIVING
-Make sure the air compressor is at a pressure of about 50 atmospheres
-If not, select either electric drive (And its coolant valve), or turbine drive if the reactor is on.
-Open the air and ballast vents and fill the front ballast to 20.000, the middle ballast to 64.000, and the aft ballast to 11.000.
-Deploy the dive planes
-Set a depth using the depth hold located on the upper panel of the con, and dive.

SURFACING
-Once again, make sure the air compressor is at a pressure of about 50 atmospheres
-If not, select either electric drive (And its coolant valve), or turbine drive if the reactor is on
-Open the FWD, MID, and AFT blower valve
-Turn on the high pressure blower valve
-Open the FWD, MID, and AFT ballast vent
-When the ballasts' aren't emptying anymore, close all valves and vents
Note: There might be about 20.000L of water left in the MID ballast, but that's fine and only helps with the stability of the ship.

WEAPON SYSTEMS
USS Walleye is loaded with 8 self homing guided torpedoes, these torpedoes are only effective against surface vessels.

-Turn on the screen
-Set the bearing you want the torpedoes to go
-Program the torpedo to your desire
-Turn the master arm key
-Open the doors of the tubes you want to fire
-Press the fire buttons

Note: For every torpedo you fire you will need to add roughly 2000L into the front ballast to keep the submarine stable.

RELOADING WEAPONS
-Empty the tube you want to empty using its drain valve and wait for it to empty
-Open the tube's hatch
-Use the pusher to load the torpedo (After 5 seconds it will return to its position)

SONAR SYSTEMS
USS Walleye is installed with brand new, state of the art, passive and active, waterfall sonar displays. Correctly using these will require some instruction.
Passive sonar
Once you turn on the sonar, you will see green patterns flowing down the screen, these mean nothing. There is also a black bar, this indicates your baffles, a blind spot caused by the ships own propellors. A contact is displayed by a bright green bar flowing down the screen, you can roughly estimate its bearing using the numbers displayed at the bottom of the screen.
Active sonar
When you turn the sonar on, you won't be able to hear anything yet. To detect other vessels, you need to press "ENABLE PING", this will send out a single ping, if you want to send more pings, press the "CONSTANT TRANSMIT" switch.
On the screen, you will now see all kinds of yellow patterns. If you see a dark and relatively large spot, you can move the cursor to said spot and select it to get its bearing and distance.

Note: When using the active sonar you will emit noise which can be heard on the passive sonar of other vessels, so I encourage you to only use active sonar when absolutely necessary.

RADAR AND ESM SYSTEM
USS Walleye is installed with one radar with a range of 5km, and an ESM system that detects radio waves.
Radar system:
-Raise the radar mast
-Turn on the radar
-Press on the left side of the screen to reduce range, and the right side to increase range.
ESM system:
-Raise the ESM mast
-Turn on the system
-When the top bar curves up it means its detecting radio waves

RADIO SYSTEM
The boat is equipped with a long range morse system with up to 360 different frequencies.
-Raise the radio mast
-Select a radio and composite frequency to receive/send at
Note: You can't send and receive at the same time

HEATING SYSTEM
Walleye uses a hot water heating system heated by the reactor.
-Turn on the reactor (If you haven't already)
-Open the boiler valve located underneath the access hatch in the engine room
-Wait until the boiler heats up to at least 50 degrees
-Turn on the heaters with the buttons located in the electric spaces

ATMOSPHERE CONTROL
One of the main limits of the Walleye is the absence of an oxygen generator, which means that oxygen is carried aboard in a large tank and has to be refilled time to time.
-Press the "TEST AIR" button
-If the oxygen levels are getting to low, add a little bit of oxygen using the "ADD OXYGEN" button
-Keep doing this when you're submerged
