On May 23, 2023, Congress was notified by congressional certification transmittal number 0G-23 of the addition of $0.7 million in non-MDE beyond what was originally notified, as well as the following non-MDE items: Mission Computer Displays and keyboards; additional spare parts, consumables, and accessories and repair and return support; and GPS receivers. The total cost of the new non-MDE articles was $3.4 million. The total case value increased to $405.4 million. There continued to be no MDE associated with this sale.
This transmittal notifies an increase in non-MDE value by $654.6 million, due to recent cost increases. This will result in a new non-MDE and overall total case value of $1.06 billion. There continues to be no MDE associated with this potential sale.
(iv) *Significance:* Recent cost increases have brought about the need to add value to the original notification. The proposed sale will improve the United Kingdom's capability to meet current and future threats by ensuring the operational readiness of the Royal Air Force. Its C-17 aircraft fleet provides strategic airlift capabilities that directly support U.S. and coalition operations around the world.
(v) *Justification:* This proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a key NATO Ally that is an important force for political stability and economic progress in Europe.
