AUKUS Undersea Defense Act

The AUKUS Undersea Defense Act authorizes the transfer of Virginia-class submarines from the U.S. Navy to Australia as part of the trilateral security partnership between the U.S., Australia, and the United Kingdom. It establishes procedures for Australia to pay for these submarines and related costs, while creating a "Submarine Security Activities Account" to accept Australian contributions for non-nuclear aspects of submarine security activities. The bill also includes provisions for repair/refurbishment of submarines and training to support the development of Australia's submarine industrial base. These measures aim to enhance undersea capabilities and defense cooperation in the Indo-Pacific region among the three nations.
