Weapon's desciption:
The GB-01 is a stealth glide bomb developed and mass produced by Shanghai Alice aircraft company with the help of Vympel NPO during the Broken Border/Gensokyo Invasion incident for the girls to fight against the Japanese naval fleet of the Outside world. It has a super powerful warhead, capable of sinking a super carrier with just one of those. It is one of the most important weapons of the incident and it earns a successful combat record with a kill ratio of around 1:2.5 (with the powerful explosive, it can even cause heavy damage to 4 cruisers at once if they stick close together).

Yes, this bomb is canon to this storyline. Though it will not present until after Touhou 16 incident in the original Touhou.

Free to use, feel free to put it on your builds.
Subassembly instruction:
1.Drag the pylon that connects to the bomb
2.Open the pylon's connections, disconnect the detacher inside of the bomb. When connecting it to your plane, make sure no part other than the detacher is connected, otherwise it will stuck to your plane.

*The rotators and gyroscope inside of the bomb has these funky input: ammo("GB-01") = 0; ammo("GB-01") < 2. These inputs make the bombs open its wings when released, based on the number of ammo you have on the plane. You can put as many as you want on your plane, when testing, mark the dropping order and change number for the wings to open properly, every other ones must use the second input for the wings to keep open during its flight, but the last one drop must have the first input mentioned above.

BOMBA GOES YEET!
