Reactive Armor:  Reactive Armor By Travis Hagan The History Behind RA:  The History Behind RA Created in 1970’s by a German inventor, in consisted of two metal plates with an explosive between them. He called in a “drive-plate explosive sandwich” Early tank defense consisted of steel plates attached to the tank’s exterior vital areas Created to protect tanks from shaped charges A Brief Overview of Shaped Charges:  A Brief Overview of Shaped Charges Discovered in 1880 in Naval Torpedo Station, Newport, Rhode Island, first applied as a Shaped Charge by the Swiss Munroe Effect US first used in 1930, Soviet Union, Germany, and Great Britain in 1940 RP antitank G, Bazooka, warhead resulted The Theory of RA:  The Theory of RA Fast moving jet of shaped charge penetrates outer metal plate and sets off explosive Explosive detonates, forces the outer metal plate to fly outward into the SC jet Plates dissipate and disperse jet Penetration by jet is severely reduced if not defeated Components of RA:  Components of RA 2 metal steel plates Explosive compound, US military uses C-4 Often a ceramic tile or composite armor is placed behind the RA to further prevent penetration by the SC Military Applications of RA:  Military Applications of RA US uses RA on HEAVY tanks only, no light-wheeled vehicles RA tiles are strategically placed on tank Since RA adds weight, the tank is not usually covered with the tiles, just covering the most vulnerable areas Advantages of RA:  Advantages of RA Increases tank crew survivability A single tile of RA is 20-30 times more effective than traditional armor Disadvantages to RA:  Disadvantages to RA Added weight decreases tank speed and maneuverability Can cause casualties to personnel near tank Cannot be placed on lightly armored vehicles such as the US APC RA armor is only effective if the shaped charge penetrates at the designed angle of impact
