Fujian Carrier Deploys Anti-Torpedo System as China Races to Neutralize US Submarine Threat
If the anti-torpedo system becomes standard on PLAN carriers, it signals that Chinese naval planners have concluded that air-defense saturation and over-the-horizon missile defense cannot reliably defeat a coordinated US submarine strike package. This forces a reallocation of design margin — every ton devoted to torpedo defense is a ton unavailable for catapult systems, arresting gear, or hangar capacity. For US Navy force structure, it validates the investment in Virginia-class SSN(X) development and the push for attack submarine force structure increases in the FY27 FYDP.
The Fujian's anti-torpedo system signals that Chinese naval architects still view US submarine-launched weapons — particularly torpedoes — as the primary kill mechanism against carrier task forces, despite a decade of PLA investments in anti-ship missiles and drone swarms.
This defensive retrofit exposes a hard constraint: China's air-defense architecture (HQ-10, HQ-16, CIWS) cannot defeat modern US submarine tactics, forcing designers to add a layer of point defense that absorbs weight, power, and berthing space that could otherwise host strike aircraft or sensors. The retrofit confirms that Beijing judges the submarine threat credible enough to trade offensive payload for survival — a calculation that INDOPACOM's submarine force structure directly influences. Watch whether the next carrier class (Type 076 LHD) adopts the same anti-torpedo suite or pivots to layered defense-in-depth instead.
Does the anti-torpedo system represent a permanent design choice for future PLAN carriers, or is it a one-off retrofit on Fujian due to late-stage design changes? The answer determines whether China is locking into a submarine-centric threat model or treating this as a transitional measure.
