Indo-Pacific Command and U.S. Forces Korea posture amid Iran war strains

Purpose

The Senate Armed Services Subcommittee on Seapower (sitting with the full committee) held a posture hearing with Adm. Samuel Paparo, commander of U.S. Indo-Pacific Command, and Gen. Xavier Brunson, commander of United Nations Command/Combined Forces Command/U.S. Forces Korea, to examine how China, North Korea, and Russia's growing alignment affects deterrence in the Indo-Pacific. Members focused heavily on how the diversion of munitions and forces to the Middle East conflict has affected readiness, along with shipbuilding, nuclear modernization, AI/chip policy, Taiwan's defense spending, and unmanned systems.

• Paparo said current U.S. shipbuilding capacity is just 0.1% of the global total, versus over 50% for China's civil-military fusion system▶ 1:49:17.

• Paparo called the U.S. AI/compute lead over China "a tenuous lead of six months to 12 months at the most," citing Chinese advantages in robotics▶ 2:27:11.
