The Fort-600 is a Ukrainian under-barrel grenade launcher designed for use with modern rifles and assault weapons. It is intended to engage enemy personnel, open positions, light fortifications, and equipment at medium ranges. The launcher fires 40 mm grenades, offering high versatility and adaptability for various mission profiles.

Its lightweight construction and ergonomic controls enable the operator to transition quickly between rifle fire and grenade launching. Mechanical sights or integration with optical systems further enhance aiming precision.

In the simulator, the Fort-600 is reproduced with realistic grenade ballistics, reloading mechanics, and weapon behavior after firing. This allows operators to practice accurate engagements on both point and area targets under different conditions, as well as refine tactical employment of under-barrel systems.
