A Russian is a short range IR-Homing Air-To-Air Missile. Although it is an air-to-air missile, it has also been used as a surface-to-air missile.
You could use it in your fighter aircrafts by attaching it to a pylon and its ready to go. I have provided 4096x4096px textures.. viz.
BaseColor
Normal
Height
Metallic
Roughness
The Maya file is the native file. The FBX file might need you to reassign textures to the material. Kindly do so if needed.
