1 open the bomb bay 2 open the Nuke (second) bay 3 drop first round 4 drop second round and 5 for the Nuke (I don't want to call it a Nuke because the Japanese doesn't have any Nuclear Weapon, yes the Nuke is fiction)

As you can see in the thumbnail how accurate is the shape, The Nuke total explosion scale is about 80. i don't make the Gunner because it's gonna take some part. Well there's no many so much thing to say.I tried my best to make it looks like the real one, please give Critics and Suggest.I guess i'll make the second version, without the Nuke.This 1 is a bit special because I made this when it was report card day. (I write this sentence with Google Translate because i don't know what the name of the "Thing that used to keep your school score")

This is the Blueprint i use

I did some test, and the result is the thing that make lag is the size of the airplane. Your device probably strong enough to hold 500 or 800 more part, but with a low graphic and no AI spawn. (Yeah some guy comment things similar to this)

In the Japanese, Fugaku mean Mount Fuji
