Don't expect this description to be great, I've got a terrible headache.

The basics:

AG3 + VTOL-slider up to retract landing gear
AG3 + VTOL-slider to the middle to extend landing gear
AG1 to fire right SharkHunter 1000
AG2 ro fire left SharkHunter 1000
AG4 to drop remaining detachers after both SharkHunter 1000 were launched
F5 to switch to TV-camera feed of right SharkHunter 1000
C to switch to TV-camera feed of left SharkHunter 1000
Throttle for engine throttle of XB-3 Penguin and both SharkHunter 1000
Pitch for elevators
Roll for ailerons

------------------------------------------------------------------------------------------------------
The XB-3 Penguin is a medium size stratosphere bomber capable of supersonic flight.
It can carry a high payload and land/takeoff on both land and water.
With the custom landing gear it also allows for very huge payloads.
A modded minigun in the nose will help you destroy ground and air based targets.
With the unlimited fuel-tank you have unlimited flight time.
------------------------------------------------------------------------------------------------------
The SharkHunter 1000 is designed to be a high precision torpedo, capable of doing a lot of damage even to the greatest ships with it's 1000 lbs warhead.
It should be dropped between 100-200 feet above sea-level and 1-4 nm away from the target.
Due to it's very stable flight and high range it can also be used as an unguided cruise missile.

Enjoy! :)
