AUKUS Pillar 2: New Partners and Opportunities

In April 2024, the governments of the AUKUS (Australia–United Kingdom–United States) security partnership announced their willingness to cooperate with Japan on advanced capabilities projects as part of AUKUS Pillar 2. To date, the group has set up eight such working groups in areas including artificial intelligence, information sharing, and hypersonic missile technology. Given Japan’s technological capabilities and close cooperation with each of the AUKUS partners, Tokyo would bring considerable value to AUKUS Pillar 2.Hudson Japan Chair Kenneth R. Weinstein will host a panel with Chris Brose of Anduril, Phoebe Greentree of the Australian Embassy, and Hudson’s David Byrd and Masashi Murano to discuss the challenges and opportunities for Japan’s potential participation in AUKUS Pillar 2, how the program may need to evolve, and the wider security and technological implications of Japanese involvement in the program.
