POLICY JUSTIFICATION
Korea--AIM-9X Sidewinder Block II Missiles
The Republic of Korea has requested to buy one hundred and three
(103) AIM-9X Sidewinder Block II tactical missiles; and ten (10) AIM-9X
Sidewinder Block II Tactical Guidance Units. The following non-major
defense equipment items will also be included: active optical target
detector; training; weapon system support; training aids and devices;
spare parts; 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 $125 million.
This proposed sale will support the foreign policy and national
security objectives of the United States by improving the security of a
major ally that is an important force for political stability and
economic progress in the Indo-Pacific region.
The proposed sale will help improve the Republic of Korea's
capability to meet current and future threats by expanding its air
defense capability, deterring aggression in the region, and ensuring
interoperability with U.S. Forces. The Republic of Korea 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.
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 this proposed sale will not require the
assignment of any additional U.S. Government or contractor
representatives to the Republic of Korea.
There will be no adverse impact on U.S. defense readiness as a
result of this proposed sale.
Transmittal No. 26-78
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 missile is a supersonic, air-to-air,
guided missile that utilizes a passive infrared target acquisition
system, proportional navigation guidance, a closed loop position servo
Fin Actuator Unit (FAU), and an active optical target detector. A solid
propellant rocket motor provides propulsion. The missile has an angular
blast fragmented warhead controlled by an Electronic Safe Arm Device.
Four control fins activated by the FAU accomplish missile maneuvering
by deflecting rocket motor thrust. The missile is used for guided
flight tracking of an airborne drone and transmits encrypted telemetry
data to aircraft or ground station receivers.
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 the Republic of Korea 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 Republic of Korea.
