It is difficult to know whether the American or Chinese submarine would win in a head-to-head fight, particularly because China has said so little about the Type 095’s capabilities.

As tensions rise between the United States and China, and as the Indo-Pacific becomes contested, tech comparisons between US and Chinese war machines are becoming relevant.

In the potential battle for control of the vast Pacific Ocean, a crucial component will take place deep underwater, where US and Chinese submarines would play a deadly cat-and-mouse game with surface vessels—and sometimes each other. The US Navy’s Virginia-class attack submarines would hunt People’s Liberation Army Navy (PLAN) submarines, surface combatants, and potentially even Chinese carrier groups. Meanwhile, China’s emerging Type 095 (or Sui-class) nuclear attack submarine is intended to substantially improve the PLAN’s ability to conduct the same missions.

On paper, both submarines are nuclear-powered, heavily armed, and optimized for stealth. Each has sophisticated sonar and long-range capability. But how do these two boats fare in head-to-head combat? The answer has clear geopolitical implications.

In Submarine Warfare, Silence Is Golden

In a head-to-head submarine engagement, the decisive factor in combat often comes down to detection. Fortunately for the United States, the Virginia’s biggest weapon is its silence. Reflecting decades of American SSN development, stretching through the preceding Los Angeles-class and Seawolf-class, the Virginia is quite advanced; its pump-jet propulsion reduces cavitation and acoustic signature, particularly when compared with conventional exposed propellers under some operating conditions. Machinery isolation and extensive acoustic treatments further suppress noise production.

While the Virginia does an excellent job at staying quiet, it’s also well equipped for detection. The Large Aperture Bow array, flank arrays, towed arrays, and BQQ-10 acoustic processing make for a formidable sonar suite. The passive sonar, in particular, is crucial; the Virginia can listen to enemy pings without transmitting active sonar and announcing its own position. In ideal circumstances, this allows the Virginia to detect and kill another boat before ever being detected itself.

The Type 095 is China’s most advanced nuclear submarine. But much of its detailed performance remains classified, and from the American perspective, entirely speculative. What is assumed is that the Type 095 represents a major acoustic improvement over China’s earlier Type 093 SSN, with quieter machinery, improved hydrodynamics, more sophisticated sonar, and potentially improved propulsion technology. Just how advanced the new Type 095 is can only be assumed. But the trend is clear: China understands that the acoustic signature has been a defining weakness of its past submarine fleets, and accordingly, it is investing heavily in closing the gap.

What Other Factors Affect Submarine Warfare?

It’s important to remember that modern submarines don’t engage in isolation. Rather, they are part of a wider network. And the Virginia-class submarine is part of that network for the US Navy—which has generations of nuclear-submarine experience, including ASW, surveillance, trailing, and long-duration Pacific deployments. The Virginia has the benefit of the US’s mature acoustic libraries, sonar processing, and quieting work, not to mention outside assistance from P-8A Poseidon aircraft, surface combatants, and intelligence.

So on paper, the Virginia class likely has an edge over the Type 095. But undersea ocean combat has many variables, and it is impossible to say with any certainty who prevails. On Beijing’s side of the ledger, the PLAN would likely be engaging with the benefit of home field advantage, operating closer to its own shore—and within a broader “kill web” including surface vessels, maritime patrol aircraft, helicopters, unmanned systems, undersea sensors, and other submarines.

Taken together, it’s a difficult comparison to draw because so little is known about the Type 095 and because so many variables determine the outcome in submarine engagements. Still, the better bet is on the Virginia class, given the US Navy’s track record.
