**POLICY JUSTIFICATION**
**Japan—Rolling Airframe Missile Block 2B Tactical Missiles**
The Government of Japan has requested to buy up to two hundred twelve (212) Rolling Airframe Missiles (RAM) Block 2B, RIM-116E. The following non-MDE items will also be included: RAM Guided Missiles Round Pack (GMRP); Tri-Pack shipping and storage containers; training equipment; operator manuals and technical documentation; U.S. Government and contractor engineering, technical, and logistics support and assistance; support for establishment of an Intermediate Level Maintenance Facility (ILMF); and other related elements of logistics and program support. The estimated total cost is $360 million.
This proposed sale will support the foreign policy goals and national security objectives of the United States by improving the security of a major ally that is a force for political stability and economic progress in the Indo-Pacific region.
The proposed sale will improve Japan's capability to meet current and future threats by providing significantly enhanced area defense capabilities over critical East Asian and Western Pacific air and sea lines of communication. It is vital to U.S. national interests that Japan develops and maintains a strong and ready self-defense capability. Japan will have no difficulty absorbing these articles 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. or contractor representatives to Japan.
There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.

(vii) *Sensitivity of Technology*
1. The RIM-116E Rolling Airframe Missile (RAM) is an autonomous, lightweight, supersonic, surface-to-air tactical missile for ship self-defense against current and evolving anti-ship cruise missile threats. Advanced technology in the RIM-116E includes dual-mode (radio frequency/infrared) (RF/IR) guidance with IR all-the-way capability for non-emitting threats.
2. The highest classification of defense articles, components, and services included in this potential sale is CONFIDENTIAL.
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 Japan 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 Japan.
