China's mysterious submarine could give US Navy a Pacific nightmare

China is currently testing an innovative uncrewed trimaran submarine that boasts an arsenal of missiles, designed to significantly strengthen its military presence against US naval forces in the Indo-Pacific. This submarine could possess between 16 and 18 of China's cutting-edge YJ-20 hypersonic anti-ship missiles. Its tactics may feature submerging before launching surprise missile strikes on enemy ships, presenting serious implications for US Navy strategic operations.
