China’s New Trimaran Submarine: 16 Missiles And An Unconventional Design

China's serial production of multiple submarine classes, including an unconventional trimaran design with extended missile payload, represents a material expansion of PLA underwater strike capacity in the Indo-Pacific. This directly threatens Australian maritime defence posture and raises the credible coercive/kinetic capability available to Beijing in a Taiwan contingency, which would draw Australia into an alliance test and degrade the regional balance on which Australian security depends.
