As Iran war fears occupy Donald Trump, reports suggest China is moving to arm its Yuan-class submarine fleet with the hypersonic YJ-19, potentially boosting its ability to threaten U.S. carrier strike groups. The scramjet-powered missile, said to exceed Mach 5 and possibly reach Mach 8, uses a “waverider” design for sustained high-speed maneuverability. Analysts warn a stealthy, submerged Yuan-class sub armed with YJ-19 could shadow U.S. naval forces undetected. The development comes as tensions rise in the Strait of Hormuz and Washington reinforces its Middle East presence.
