**POLICY JUSTIFICATION**
**Switzerland—PATRIOT Sustainment**
The Government of Switzerland has requested to buy sustainment support for its five (5) PATRIOT Fire Units and missile inventory. The following non-MDE items will be included: general electronic test station equipment and program sets; Foreign Liaison Officer support; international engineering services; Field Surveillance Program; modification and upgrade kits; unclassified and classified repair and return; classified missile processing; unclassified and classified spares; transportation; publications and technical documentation; training; U.S. Government and contractor technical, engineering, and logistics support services; and other related elements of logistics and program support. The total estimated cost is $450 million.
This proposed sale will support the foreign policy and national security objectives of the U.S. by helping to improve the security of a friendly European nation that continues to be an important force for political stability and economic progress within Europe.
The proposed sale supports Switzerland's goal of maintaining national and territorial defense as well as interoperability with U.S. and other European forces. Switzerland will have no difficulty absorbing this equipment and services into its armed forces.
The proposed sale of this equipment and support will not alter the basic military balance in the region.
The prime contractors will be RTX Corporation, located in Tewksbury, MA; Lockheed Martin, located in Dallas, TX; and Leidos, located in Huntsville, AL. The purchaser typically requests offsets. Any offset agreement will be defined in negotiations between the purchaser and the contractor.
Implementation of this proposed sale will require no U.S. Government representatives but will require approximately ten contractor representatives to travel to Switzerland for an extended period of time to provide technical support.
There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.
