class: SHORAD description: The M6 Linebacker short-range air defense system was developed by Boeing to meet the US Army requirements. The new vehicle was intended to counter the threat posed by low-flying aircraft, helicopters, cruise missiles and unmanned aerial vehicles to forward armored formations. Initial production Linebackers entered service with the US Army in 1997. A total of 99 Bradley Linebackers were ordered, however in 2006 these were phased-out of service. The M6 is an all-weather system, capable of operating in day/night and all weather conditions. It is based on the M2 Bradley IFV and is equipped with a quadruple launcher with FIM-92 Stinger short-range surface-to-air missiles instead of the TOW ATGW. introduced: 1997 manufacturer: United Defense origin: USA price: 18 role: Self-Propelled Anti-Aircraft System variants: M6 Linebacker: {}
