Underbody armor refers to protective plating installed on the underside of vehicles, particularly military and off-road vehicles. Its primary purpose is to shield the vehicle's vital components from explosive devices, such as landmines and improvised explosive devices (IEDs). This armor is designed to absorb and dissipate the energy from blasts, reducing the risk of damage and injury to occupants. The materials used in underbody armor can vary, including steel, aluminum, and composite materials, each offering different levels of protection and weight. The effectiveness of underbody armor is crucial for enhancing the survivability of vehicles in combat zones, making it an essential feature for military operations and tactical missions involving armored vehicles.
