PLA Navy Conducts First Public Submarine-Launched Ballistic Missile Test Into South Pacific

China's PLA Navy conducted its first publicly disclosed test launch of a submarine-launched ballistic missile (SLBM), reportedly a JL-3-class weapon with a dummy warhead and estimated range of 7,300–10,000 km, on July 6, 2026 (12:01pm China Standard Time per the PLA's own statement). The missile overflew the Philippines' Exclusive Economic Zone and landed in international waters of the South Pacific near the Kiribati/Tuvalu EEZ — within the South Pacific Nuclear Free Zone. It is the first public demonstration of China's submarine-based nuclear second-strike capability in the Indo-Pacific and coincided with the US-led RIMPAC exercise. Japan said it was notified in advance and expressed concern; New Zealand and Australia lodged protests over the missile's transit near the South Pacific Nuclear Free Zone. Beijing's Foreign Ministry (spokesperson Mao Ning) and PLAN spokesperson Senior Capt. Wang Xuemeng characterized the launch as 'routine' military training conducted in compliance with international law and 'not targeting any specific country.' While not a Taiwan Strait event per se, the test is being read by regional analysts as a significant nuclear-signaling data point in the broader China-US-Taiwan strategic balance, occurring one day before renewed PLA ADIZ sortie activity around Taiwan on July 7–8.
