The US Defense Security Cooperation Agency (DSCA) has notified Congress of a potential sale of PATRIOT Advanced Capability (PAC) 3 Missile Segment Enhanced (MSE) missiles to Switzerland.

The estimated cost of the missiles and associated equipment is valued at $700m. The defence articles are being obtained through the US Foreign Military Sale route.

Approved by the US State Department, the proposed sale package includes 72 PAC 3 MSE missiles, PAC-3 MSE missile rounds and empty round trainers, PAC-3 missile skid kits, classified and unclassified PAC-3 concurrent spare parts, and PAC-3 MSE canister consumables.

The Government of Switzerland has also requested to purchase telemetry kits, launcher station heater controls, classified missile repair and return, technical assistance, and other logistics and programme related support.

Lockheed Martin in Dallas, Texas, will act as the prime contractor.

Approximately five US Government and five contractor representatives will be assigned to Switzerland to provide equipment de-processing/fielding, and technical and logistics support.

According to the US Army, PAC-3 MSE is a high velocity, hit-to-kill, surface-to-air missile that employs kinetic energy to intercept and destroy tactical ballistic missiles, air-breathing threats, and evolving targets.

With this capability, Switzerland will increase the performance of its PATRIOT missile defence system and can better defend territorial integrity and maintain stability regionally.

The PATRIOT system and missiles will also enhance the country’s ‘interoperability with US and Nato forces’.

In a statement, the DSCA said: “This proposed sale will support the foreign policy and national security objectives of the United States 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.”

Last year, Lockheed Martin delivered the first PAC-3 MSE missiles to Sweden.
