WASHINGTON, August 6, 2025 - The State Department has made a determination approving a possible Foreign Military Sale to the Government of Australia of MC-55A Baseline 2 Upgrade and related equipment for an estimated cost of $404 million. The Defense Security Cooperation Agency delivered the required certification notifying Congress.
The Government of Australia has requested to buy equipment and services to support maintenance of its MC-55A aircraft fleet, to include major and minor modifications; spare parts; consumables and accessories; repair and return support; 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 $404 million.
This proposed sale will support the foreign policy and national security objectives of the United States. Australia is one of our most important allies in the Western Pacific. The strategic location of this political and economic power contributes significantly to ensuring peace and economic stability in the region. It is vital to the U.S. national interest to assist our ally in developing and maintaining a strong and ready self-defense capability.
The proposed sale will improve Australia’s capability to maintain its fleet of MC-55A aircraft that enhances its ability to conduct effective air operations and supports U.S. operations in the region. Australia 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 L3 Harris, located in Greenville, TX. 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 Australia.
There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.
The description and dollar value are for the highest estimated quantity and dollar value based on initial requirements. Actual dollar value will be lower depending on final requirements, budget authority, and signed sales agreement(s), if and when concluded.
All questions regarding this proposed Foreign Military Sale should be directed to the State Department's Under Secretary of State for Arms Control and International Security, Political-Military Affairs Outreach, at T_Outreach_PM@state.gov.
