Also being classified as an underwater command sub is the heaviest submarine I've ever made. Armed with 32 torpedoes & 2 Anti Air Guns, the submarine carries a single scout plane armed with a small dive bomb made by WalrusAircraft's & was modified by kikasshes and can be launched using the deck catapult system and it could also be recovered by using the small crain. The aircraft sub can dive down to -80ft below the surface, with a top speed of only 70mph I'd say this aircraft sub is slightly fast for her class.

Controls:
-Throttle forward
-Roll (Left\Right)

1: Launch all torpedoes
2: Diving system (VTOL UP)
3: HInge rotator
4: Activate Aircraft
5; Launch Aircraft
6: Activate Crane (VTOL UP) (TRIM TO ROTATE) (Pitch down to use the magnet)
7: Activate anti-air guns and drop a dive bomb
8: Propulsion

How To Launch Aircraft (MUST READ)
-The Submarine must be at full speed
-Activate 4 to turn on the aircraft
-Activate 3 VTOL Up Just Half
-Deactivate 3 and Pitch down to bring the plane forward
-When the aircraft is in forwarding position activate 5 to launch aircraft

I recommend using the mouse as joystick to fly easier

Note: if you want to know how to stop the submarine while controlling the aircraft throttle down, deactivate 8, & throttle up again.

Enjoy!
