Weapon's desciption:
The R-77X Black Comet is a next-gen stealth variant of the infamous R-77M developed by Vympel NPO, later brought into Gensokyo by Sanae during the Broken Border/Gensokyo Invasion incident for the Gensokyo Fighters squadron to use as their primary weapon against the Japanese aircrafts (The squadron has 5 members: Reimu, Marisa, Sanae, Sakuya, Youmu). It has the most successful combat record in the incident with a kill ratio of 1:1, not a single miss. It's also a missile feared by many countries in the Outside World due to its relatively low cost for its specs (around 500k$ per missile), extremely high maneuverability, a silent radar tracking system and stealth capability (the missile can lock on and silently fly to the target aircraft without triggering any sensor or apppearing on any radar), a range of 200km and a top speed of mach 4.5, making it the most dangerous and one of the fastest solid fuel air-to-air missile in the Outside World, earning itself the nickname Black Comet.

This missile is canon to this storyline but it will not present on my Touhou aircrafts until after Touhou 16’s incident in the original Touhou.

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

The Comet is coming... can you hear it?
