**POLICY JUSTIFICATION**
**The Netherlands—AIM-9X Sidewinder Block II Missiles**
The Government of the Netherlands has requested to buy two hundred forty-six (246) AIM-9X Sidewinder Block II tactical missiles; six (6) AIM-9X Block II sidewinder captive air training missiles (CATM); two (2) AIM-9X Block II Sidewinder special air training missiles; fourteen (14) AIM-9X Block II Sidewinder tactical guidance units; and two (2) AIM-9X Block II Sidewinder CATM guidance units. Also included are missile containers; spares; personnel training and training equipment; classified and unclassified publications and technical documents; warranties; U.S. Government and contractor engineering, technical, and logistics support services; and other related elements of logistics and program support. The estimated total program cost is $691 million.
This proposed sale will support the foreign policy goals and national security objectives of the United States (U.S.) 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 the Netherlands' capability to meet current and future threats and enhance interoperability with the U.S. and other NATO members. The Netherlands will have no difficulty absorbing these weapons into its armed forces.
The proposed sale of this equipment and support will not alter the basic military balance in the region.
The principal contractor will be RTX Corporation, located in Tucson, AZ. There are no known offset agreements 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 the Netherlands; however, U.S. Government Engineering and Technical Services may be required on an interim basis for training and technical assistance.
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 AIM-9X Block II Sidewinder missile represents a substantial increase in performance over the AIM-9M and replaces the AIM-9X Block I missile configuration. The missile includes a high off-boresight seeker, enhanced countermeasure rejection capability, a low drag/high angle of attack airframe and the ability to integrate the Helmet Mounted Cueing System. The most current AIM-9X Block II operational flight software developed for all international partner countries and authorized by U.S. export policy provides fifth-generation infrared missile capabilities such as Lock-On-After-Launch, Weapons Data Link, surface attack, and surface launch. No software source code or algorithms will be released.
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 weapon system effectiveness or be used in the development of a system with similar or advanced capabilities.
4. A determination has been made that the Netherlands can provide substantially the same degree of protection for the sensitive technology being released as the U.S. Government. This 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 the Netherlands.
