**Australia—M142 High Mobility Artillery Rocket Systems**
The Government of Australia has requested to buy forty-eight (48) M142 High Mobility Artillery Rocket Systems (HIMARS). The following non-MDE items will also be included: M1084A2 HIMARS resupply vehicles; M1095 trailers; Low Cost Reduced Range Practice Rocket (LCRRPR) pods; intercom systems; radio and communication mounts; spare parts and services; U.S. Government and contractor engineering, technical, and logistics support services; studies and surveys; and other related elements of logistics and program support. The estimated total cost is $705 million.
This proposed sale will support the foreign policy and national security objectives of the U.S. Australia is one of the United States' 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 Western Pacific. It is vital to the U.S. national interest to assist this ally in developing and maintaining a strong and ready self-defense capability.
The proposed sale will improve Australia's capability to meet current and future threats and will enhance interoperability with U.S. forces and other allied forces. Australia will use the capability to strengthen its homeland defense and provide greater security for its critical infrastructure. Australia will have no difficulty absorbing this equipment 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 Lockheed Martin, located in Grand Prairie, TX; L3Harris Corporation, located in Melbourne, FL; Leonardo DRS, located in Arlington, VA; and Oshkosh Corporation, located in Stafford, 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 Australia.
There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.
