Wide Area Air Defense System

Type: High altitude air defense system
Manufacturers: Raytheon, Lockheed Martin, Motorola, Emerson Electric

Missile Used: MIM-161C Land Standard Missile
System Components: AN/MPQ-121 and AN/MPQ-122 Radar set, AN/MSQ-104B Engagement control station, OE-349 Antenna Mast Group, EPP-IV electric power plant, multiple M1098 launching stations

Range: Above 500 km (310 mi)
Flight Ceiling: Above 250 km (155 mi)

The WAADS system is meant as the replacement for the MIM-104 Patriot in the ultra-long-range air defense category, and will provide the United States with the ability to intercept some ICBM missiles. Design primarily to compete with the Russian/Chinese S-500 missile system, the WAADS system uses some of the electronics of the PAC-3 Patriot missile system, but uses the much longer-ranged Standard Missile 3 missile system, and uses a modified form of the US Navy's AN/SPG-62 guidance radars in order to guide the missile.

The US Army hopes to have the WAADS system work with the Patriot PAC-3, and the system is hoped to be in service by mid to late 2014.
