POLICY JUSTIFICATION

Spain—Sonar Upgrade Kits

The Government of Spain has requested to buy seven (7) Sonar, Mine Hunting, AN/SQQ-32(V)3+ upgrade kits. The following non-MDE items will also be included: towed body parts; support equipment; spare parts, consumables, and accessories; unclassified operation and maintenance software; unclassified publications, technical documentation; and studies and surveys; 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 $75 million.

This proposed sale will support the foreign policy goals and national security objectives of the United States by improving the security of a NATO ally that is a force for political stability and economic progress in Europe.

The proposed sale will improve Spain's capability to meet current and future threats by providing an advanced and reliable sonar system, enhancing its ability to detect, classify, and neutralize underwater threats. This modernization prevents a capability gap in Spain's Mine Countermeasure forces and ensures continued contribution to NATO maritime security operations. Spain will have no difficulty absorbing these articles and services into its armed forces.

The proposed sale of this equipment and support will not alter the basic military balance in the region.

There is no principal contractor in connection with this sale. The articles and support will be provided by the Naval Surface Warfare Center, located in Panama City, FL. At this time, the U.S. Government is not aware of any offset agreement proposed in connection with this potential sale.

Implementation of this proposed sale will not require the assignment of any additional U.S. Government or contractor representatives to Spain.

There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.

Annex

Item No. vii

(vii) Sensitivity of Technology:

1. The AN/SQQ-32 sonar is a variable-depth mine-hunting sonar system designed for detecting and classifying moored and bottom mines in mine countermeasure operations. It includes two separate active sonar systems to detect and classify mine-like objects on the surface in the volume or on the bottom of the sea. The sonar systems are packaged in a single towed body tethered to the ship through a cable providing power and data transmission with the cable length variable via an electric winch.

2. The detect and classify sonar subsystems are independently monitored and controlled by two operators at independent panels working together to find and characterize underwater objects as mine or non-mine like objects. The detection system is a low frequency, low resolution, high range sonar designed to provide a general location of possible mine-like objects. It provides much greater range than the classify sonar system, but provides little resolution and detail of the objects it detects. The classify sonar has a lower range, but higher frequency and higher resolution, allowing the classification of a target as mine-like or non-mine-like.

3. The highest level of classification of defense articles, components, and services included in this potential sale is SECRET.

4. If a technologically advanced adversary were to obtain knowledge of the specific hardware and software elements, the information could be used to develop countermeasures that might reduce system effectiveness or be used in the development of a system with similar or advanced capabilities.

5. A determination has been made that Spain can provide substantially the same degree of protection for the sensitive technology being released as the U.S. Government. This proposed sale is necessary in furtherance of the U.S. foreign policy and national security objectives outlined in the Policy Justification.

6. All defense articles and services listed in this transmittal have been authorized for release and export to the Government of Spain.
