China’s Fujian Carrier Equipped with cutting‑Edge Anti‑Torpedo Defense

The latest Fujian aircraft carrier, China’s newest warship, is slated to carry an advanced anti‑torpedo system designed to neutralize incoming torpedoes, underscoring the nation’s growing blue‑water ambitions and the persistent danger from hostile submarines.

According to a recent South China Morning Post report, the Fujian will become the world’s first carrier fitted with an active anti‑torpedo torpedo (ATT) system, granting it a sophisticated “hard‑kill” capability against modern Western submarines.

The carrier, China’s third and first domestically designed carrier, replaces the traditional 12‑tube depth‑charge launchers with a six‑tube, 324‑millimeter lightweight torpedo launcher.

The system appears to counter the “severe threat” posed by the U.S. Navy’s Seawolf‑class submarines and future SSN(X) vessels, which wield heavy wire‑guided torpedoes capable of inflicting catastrophic damage on large warships.

The interceptor employs a broadband sonar array to separate genuine targets from decoys and a high‑torque permanent‑magnet pump‑jet thruster that propels the weapon to 50–60 knots within three seconds, allowing it to engage highly maneuverable torpedoes.

To ensure a single‑hit kill, the ATT launches directional shaped charges and over‑pressure shockwaves, with potential supercavitation upgrades that could boost defensive speeds to as high as 200 knots for close‑range underwater threats.

China’s development of an active ATT for the Fujian seeks to offset its still‑vulnerable anti‑submarine warfare (ASW) shortcomings by strengthening the carrier strike group’s point‑defence layer against advanced U.S. undersea threats.

Current carrier doctrine highlights China’s ASW deficiencies, as carriers are typically positioned close to the coast under the protection of land‑based missile networks and aircraft rather than relying on robust onboard defenses, a strategy that diverges sharply from the United States’ practice of positioning carriers as roaming nerve centers.

Consequently, Chinese carriers remain exposed to direct attack, particularly from U.S. Virginia‑class submarines equipped with Mk48 heavyweight torpedoes and Maritime Strike Tomahawk missiles.

Limitations in PLAN airborne ASW stem from a shortage of fixed‑wing maritime patrol aircraft, lagging operator proficiency, and training constraints that reduce realism, according to a May 2024 CMSI analysis.

A US‑China Economic and Security Review Commission testimony in March 2026 noted additional systemic weaknesses, including deficient meteorological and oceanographic data, scarce deployed sensors, limited patrol aviation, and logistical shortfalls that hinder out‑of‑area ASW operations.

Andrew Erickson highlighted in the same testimony that the PLAN’s ASW performance is further hampered by a lack of deployed sensors, inadequate real‑time data fusion, and complex intra‑service coordination, especially in mine counter‑measures and sensor integration.

While the PLAN boasts the world’s largest fleet, the U.S. Navy retains a clear advantage in submarine stealth, with acoustic signatures remaining a persistent vulnerability for Chinese submarines.

Acoustic assessments from a June 2026 SCSPI report indicate that newer Chinese nuclear‑attack (Type 093) and ballistic‑missile (Type 094) submarines are louder than their U.S. counterparts, though recent engineering refinements—such as lower‑vibration machinery and reverse‑engineered Russian pneumatic isolation mounts—are closing the gap.

The forthcoming third‑generation Type 095 SSN and Type 096 SSBN are expected to approach Russian Improved Akula‑class stealth levels, while forward‑deployed U.S. attack submarines continue to operate in the South China Sea, supported by auxiliary tenders such as the USS Emory S. Land and USS Frank Cable.

China’s next carrier, likely nuclear‑powered, may eventually project power beyond the First Island Chain, requiring greater reliance on onboard, all‑aspect defenses rather than land‑based support.

A June 2024 CMSI study by Daniel Rice describes a three‑zone defensive architecture for Chinese carrier strike groups: a deep defense zone extending 185–400 km guarded by submarines and long‑range J‑15 fighters; a middle zone of 45–185 km protected by destroyers and frigates; and a point‑defense zone of 100 m–45 km employing terminal systems to intercept threats that breach outer layers.

Within this structure, the Fujian’s ATT system is poised to reinforce the point‑defense layer, providing an additional, technology‑rich shield.

The ultimate challenge will not be merely installing advanced defenses on individual vessels but integrating sensors, escorts, aircraft, submarines, and command networks into a cohesive, survivable carrier ecosystem capable of operating in contested undersea environments where U.S. submarines retain a quiet edge.
