Armor is the major element in penetration avoidance, and damage reduction deals with firefighting agents and compartmentalization of ammunition and fuel. Advances in penetration avoidance center on producing efficient armors with reduced weight, space, and cost. Mobility components include suspension, tracks, wheels, engine, transmission, and fuels and lubricants. Another major area of interest is providing increased electrical power in smaller, lighter packages. Electrical power is shared among propulsion, survivability, lethality, and auxiliary systems.
Energy management is an important factor.
Electric and hybrid drive systems are also being developed. Finally, to reduce operation and support costs, the number and types of fuels and lubricants must be reduced. The major players in ground vehicle systems integration and design are the U.K., France, Germany, Israel, Japan, and Russia, all of whom have a long history of developing and manufacturing military armored systems including main battle tanks. Switzerland also has a capability in armored vehicles. These countries have strong capabilities in vehicle chassis and turret technologies.
