WASHINGTON, January 29, 2026 - The State Department has made a determination approving a possible Foreign Military Sale to the Government of Spain of F-100 Frigate Mid-Life Upgrade and related equipment for an estimated cost of $1.7 billion. The Defense Security Cooperation Agency delivered the required certification notifying Congress.
The Government of Spain has requested to buy five (5) Shipsets AEGIS Weapon System; six (6) Shipsets Digital Signal Processor; five (5) Shipsets MK 41 Baseline VIII Vertical Launching System; five (5) Shipsets of Next Generation Surface Search Radar. The following non-major defense equipment articles (MDE) will also be included: ultra high frequency satellite communications radio terminal systems; Global Positioning System Miniature Precision Lightweight GPS Receiver Engines with M-Code; AN/SRQ-4 Ku-band hardware; material required to support the upgrade of NIXIE SLQ-25A to a SLQ-25E; MK 331 Torpedo Setting Panels; MK 32 surface vessel torpedo tube upgrades; U.S. Government support for the MK 45 Mod 2 and Mod 2B Gun Weapon System; modernization efforts, integration, and test support and equipment; munitions support and support equipment; spare parts; consumables and accessories; repair and return support; classified software delivery and support; classified and unclassified publications; technical documentation; personnel training and training equipment; studies and surveys; Contractor Logistics Support; U.S. Government and contractor engineering, technical and logistics support services; and other related elements of logistics and program support. The estimated total cost is $1.7 billion.
The proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a NATO Ally that is an important force for political stability and economic progress in Europe.
The proposed sale will improve Spain's capability to meet current and future threats by affording more flexibility and capability to counter regional threats and continue to enhance stability in the region. The purchaser will use the articles and services to modernize five AEGIS-equipped frigates within its fleet, enhancing its ability to conduct defense missions and interoperate with the U.S. and NATO Allies for theater ballistic missile defense. Spain will have no difficulty absorbing this equipment and support into its armed forces.
The proposed sale of this equipment and support will not alter the basic military balance in the region.
The principal contractors will be Lockheed Martin, located in Moorestown, NJ, and Manassas, VA; RTX Corporation, located in Arlington, VA; Ultra Maritime Naval Systems and Sensors, located in Braintree, MA; and General Dynamics, located in Williston, VT. At this time, the U.S. Government is not aware of any offset agreement proposed in connection with this potential sale. Any offset agreement will be defined in negotiations between the purchaser and the contractor.
Implementation of the proposed sale will require U.S. Government and contractor personnel to visit Spain on a temporary basis in conjunction with program technical oversight and support requirements, including program and technical reviews, as well as to provide training and maintenance support in country.
There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.
The description and dollar value are for the highest estimated quantity and dollar value based on initial requirements. Actual dollar value will be lower depending on final requirements, budget authority, and signed sales agreement(s), if and when concluded.
