POLICY JUSTIFICATION

Brazil—FIM-92K Stinger Missiles

The Government of Brazil has requested to buy one hundred (100) FIM-92K Stinger Block I missiles. The following non-major defense equipment items will also be included: gripstocks; engineering assistance; integration support services; 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 $330 million.

This proposed sale will support the foreign policy and national security objectives of the United States by helping to improve the security of an important regional partner that is a force for political stability and economic progress in South America.

The proposed sale will improve Brazil's capability to meet current and future threats by providing the FIM-92K Stinger Block I missiles and thereby enhancing its air defense capability. This will contribute to the goals of enhancing interoperability with the United States and other allies. Brazil will have no difficulty absorbing these articles and services into its armed force.

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

The principal contractors will be RTX Corporation, located in Arlington, VA and Lockheed Martin, located in Syracuse, NY. 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 this proposed sale will not require the assignment of any additional U.S. Government or contractor representatives to Brazil.

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. FIM-92K Stinger Block I is primarily in the area of design and production know-how and not end-items. This sensitive and critical technology is inherent in the hybrid microcircuit assemblies; micro-processors; magnetic and amorphous metals; purification; firmware; printed circuit boards; laser roll rate sensor; dual detector assembly; detector filters; optical coatings; ultraviolet sensors; compounding and handling of electronic, electro-optic, and optical materials; test equipment operating instructions; energetic materials fabrication and loading technology; and warhead components and seeker assembly.

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

3. 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.

4. A determination has been made that Brazil 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.

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