RIM116 Rolling Airframe Missile (RAM) Launcher (Anti Missile) turret. Modeled after photo reference. Can be used in future (space)ships too.
Modeling is done in Lightwave3D. LWO version comes with procedural and UV versions, where the UV uses baked textures, making this version suitable for gaming too. Other formats are converted by Deep Exploration, and they are also completely uv mapped.
