Developed under the "Intermediate Fighter Program" the JS-31 was modernized, named the JS-31C. Exeron adopted it for the ESADF, though the original JS-31 had only recently been transferred from the ESAS to the ESADF. the JS-31C is Exeron's common "Frontline Fighter", used more in the offensive role as opposed to the SF-27DV in its Site Defense role and the JS-40E in its Mainland Defense role.

I am going to let you guys guess what I was referencing with the name (Skeletá) and the markings on the aircraft

I can't fully remember the activation groups, but:
AG-1: Cockpit
AG-3: Tailhook
AG-4: Arm Missiles & Taxi Engine
AG-7: Eject

THERE ARE A LOT OF MISSILES BTW
You might need to actually remove some for performance (theres 26)
