POLICY JUSTIFICATION
Belgium--AIM-9X Sidewinder Missiles
The Government of Belgium has requested to buy three hundred twenty
(320) AIM-9X Block II Sidewinder tactical missiles; two hundred fifty-
eight (258) AIM-9X Block II+ Sidewinder tactical missiles; fifty (50)
AIM-9X Block II tactical guidance units; and thirty (30) AIM-9X Block
II+ tactical guidance units. The following non-Major Defense Equipment
items will also be included: missile containers; weapon software;
transportation; U.S. Government and contractor engineering,
[[Page 3471]]
technical, and logistical support services; and other related elements
of logistics and program support. The estimated total cost is $567.8
million.
This proposed sale will support the foreign policy and national
security objectives of the 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 Belgium's capability to meet current
and future threats by providing air-to-air missiles and guidance units
for Belgium's F-35 fleet in support of NATO's defense mission. Belgium
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
Arlington, VA. 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 the assignment of
four U.S. Government and two contractor representatives to Belgium on a
temporary basis in conjunction with program technical oversight and
support requirements.
There will be no adverse impact on U.S. defense readiness as a
result of this proposed sale.
Transmittal No. 25-66
Notice of Proposed Issuance of Letter of Offer Pursuant to Section
36(b)(1) of the Arms Export Control Act
Annex
Item No. vii
(vii) Sensitivity of Technology:
1. The AIM-9X Sidewinder Block II and Block II+ missile represents
a substantial increase in missile acquisition and kinematics
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, low drag/high angle of
attack airframe, and the ability to integrate the helmet mounted cueing
system. The software algorithms are the most sensitive portion of the
AIM-9X missile. The software continues to be modified via a pre-planned
product improvement (P\3\I) program to improve its counter-
countermeasure capabilities. The most current AIM-9X Block II/II+
operational flight software developed for all international partner
countries, which is authorized by U.S. Government export policy,
provides fifth-generation infrared missile capabilities such as Lock-on
after launch, weapon 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 system
effectiveness or be used in the development of a system with similar or
advanced capabilities.
4. A determination has been made that Belgium 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
Belgium.
