**POLICY JUSTIFICATION**
**Ukraine—PATRIOT Air Defense System Sustainment**
The Government of Ukraine has requested to buy sustainment related articles and services for the PATRIOT air defense system, including the upgrade of M901 launchers to M903 configuration; classified and unclassified prescribed load lists and authorized stockage lists for ground support equipment; other necessary services, ancillaries, spare parts, support, training, and accessories; and other related elements of logistics and program support. The estimated total cost is $105 million.
This proposed sale will support the foreign policy and national security objectives of the United States (U.S.) by improving the security of a partner country that is a force for political stability and economic progress in Europe.
The proposed sale will improve Ukraine's ability to meet current and future threats by further equipping it to conduct self-defense and regional security missions with a more robust local sustainment capability. Ukraine 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 contractors will be RTX Corporation, located in Arlington, VA, and Lockheed Martin, located in Bethesda, MD. 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 require the assignment of approximately five additional U.S. Government and fifteen U.S. contractor representatives to the European Combatant Command for the duration of up to one month to support training and periodic meetings.
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 PATRIOT air defense system contains sensitive and critical technology. The M903 upgrade will allow for deployment of all the munitions fieldable with the M902 configuration as well as the PATRIOT Advanced Capability-3 (PAC-3) Missile Segment Enhanced (MSE) munition. The MSE variant of the PAC-3 is the next generation of hit-to-kill interceptors and provides expanded battlespace against evolving threats.
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 Ukraine 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 Ukraine.
