Ag1-fan missile launcher (when you are going to fire the missiles dont pull up or you'll explode).

Ag2-jettison railgun (railgun might get caught on the tail).

Ag3-arm railgun (to fire hit the gun button).

Ag4,5,6,7-AA missiles.

Ag8 deactivated-3 frontal engines and one rear engine are shutdown for long range flight (when ag8 is deactivated be careful when pitching as it might spin out. Also before an engagement make sure ag8 is active).

Have fun!Thx to spefyjerbf for fan missile launchers.
When landing on water keep the nose up. Also if the tail is underwater its ok

CAUTION-while firing the machine guns the aircraft may spontaneously combust for some odd reason. If you can solve this problem I would greatly appreciate it. Also after you takeoff from the water the missiles from the launchers and under the wing would fail to engage often resulting in a possible explosion later on.
