The Chilean Government is seeking to procure Standard Missile-2 (SM-2) Block IIIA missiles through the US foreign military sale (FMS) programme.

Approved by the US State Department, the potential FMS has an estimated value of $85m.

Under the proposed sale package, Chile has requested for the supply of 16 SM-2 Block IIIA rail launched missiles, two MK 89 Mod 0 guidance sections, and one target detection device kit, including shroud and MK 45 Mod 14.

It also includes the sale of Intermediate Level Maintenance Facility, spare parts and related equipment, as well as publications and technical data. Personnel will also be provided with training, technical support, and other associated logistics and programme assistance.

US Congress has been notified by the US Defense Security Cooperation Agency (DSCA).

DSCA said in a statement: “This proposed sale will support the foreign policy goals and national security objectives of the United States by improving the security of a strategic partner in South America.”

The Chilean Navy is expected to deploy the missiles to its two Adelaide-class frigates to boost anti-air warfare capabilities.

The two ex-Royal Australian Navy (RAN) frigates were acquired by the Chilean Navy to replace its second-hand vessels procured from the Netherlands in 2004.

The SM-2 is designed to help navies defend against anti-ship missiles and aircraft out to 90nm and a 65,000ft altitude.

Raytheon Missiles and Defense has been appointed as the principal contractor for the sale.

To date, the company has delivered more than 11,000 SM-2 missiles to customers globally.

In 2017, Raytheon announced the restart of its SM-2 production line following the receipt of $617.6m full-rate production contract from the US Department of Defense.

The fiscal 2017 order involved the supply of SM-2 missiles to the US and four allied foreign navies of the Netherlands, Japan, Australia and South Korea.

Last year, the first SM-2 missile from the company’s restarted production line was successfully flight-tested.
