WASHINGTON – The U.S. State Department has cleared Spain to purchase five Aegis weapon systems, potentially worth $860.4 million.

The systems would be placed aboard Spanish frigates, which are interoperable with NATO allies such as the U.S. Spain currently operates five existing Aegis-equipped frigates.

Adding the systems to Spain’s fleet will “afford more flexibility and capability to counter regional threats and continue to enhance stability in the region,” according to an announcement posted by the Defense Security Cooperation Agency.

In addition to the five systems, the package includes six shipsets Digital Signal Processing, five shipsets AWS Computing Infrastructure MARK 1 MOD 0, five shipsets Operational Readiness Test Systems (ORTS), five shipsets MK 99 MOD 14 Fire Control System, five shipsets MK 41 Baseline VII Vertical Launching Systems (VLS), two All-Up-Round MK 54 Mod 0 lightweight torpedoes, twenty SM-2 Block IIIB missiles and MK 13 canisters with AN/DKT-71 warhead compatible telemeter, as well as other equipment.

Being cleared by the State Department does not guarantee a sale will be completed. Congress can still intervene, and final price and quantity are often altered during negotiations. The proposed sale is being handled under a Foreign Military Sales vehicle.

Should the sale clear, it primary work would be done by Lockheed Martin in Moorestown, NJ, and Manassas, VA; Raytheon in Waltham, MA; and General Dynamics in Williston, VT.
