You can move the cannon behind the turret so it looks better, I put it in front so you can see what its doing. Hold down the F (for fire) key until it fires. When you reload the cannon you have to hold the L key until the mechanism goes all the way behind the next shell, then let go of the L key.
It still has problems but Im new at Phun, I will post the finished version.

Controls:
Right, left= Forward reverse

Up, down= raise and lower cannon

F= fire cannon

L= reload cannon

O and C= open and close hatches
