Could Russian or Chinese Submarines 'Sink' the U.S. Navy in a War?

The problem is not just that the U.S. Navy has not invested in the necessary ASW hardware—there is also a real training deficit. “We notice because we have not made the investments necessary to keep our anti-submarine capabilities up to snuff. The carrier no longer has the S-3 Viking and the skills of the dipping-sonar helicopters hasn't been honed enough in exercises in recent years to assure carrier strike group commanders that they are safe in contested waters,” Hendrix said. “Also, our surface force, with their bow-mounted sonars and passive tails, have also not been exercised enough—especially against tough targets like advanced nuclear submarines or some of the top-of-the-line diesel boats—to really know what they are doing.”

While the U.S. Navy has been sounding the alarm about a resurgent Russian and growing Chinese submarine threat, much of the problem stems the service’s much diminished anti-submarine warfare (ASW) capabilities. Even the combined might of today’s Russian and Chinese submarine fleet does not come close to matching the capabilities or threat posed by the once-mighty Soviet Navy—which boasted roughly 240 submarines before the 1991 collapse of the Soviet Union.

During the late Cold War-era, Soviet designers and a number of Western analysts believed that the Soviet Union was starting to pull ahead of American designs in terms of acoustical stealth—according to a recent Center for Strategic and International Studies (CSIS) report titled Undersea Warfare in Northern Europe. But Russian technological progress came to a virtual standstill in the aftermath of the Soviet collapse. Nonetheless, since 1991, while Moscow has tried to push forward with late Soviet-era innovations, the social, economic and political upheaval of the 1990s essentially resulted in a lost decade for the Russian submarine force as funding slowed to a trickle.

“The Russians have continued to move forward with a series of technological improvements that emerged at the end of the Soviet Union but the new Russia was unable to capitalize on due to a small budget,” said retired U.S. Navy Capt. Jerry Hendrix, director of the Defense Strategies and Assessments Program at the Center for a New American Security. “However, the United States and its alliance partners, distracted by wars in Iraq and Afghanistan, have allowed their ASW abilities to atrophy.”

As the CSIS report notes, the present day Russian Federation Navy has about 56 submarines in total—which is roughly one-fifth of the size of the Soviet undersea force. Moreover, as CNA Corporation research scientist Mike Kofman has noted, at best, half of Russia’s submarine fleet is operational at any one time. One example cited in the CSIS study is the Russian Northern Fleet, which nominally operates 42 submarines but only 22 to perhaps 31 are operational vessels. “One of the most puzzling things you’ll ever hear is when people say the Russian submarines are operating at Cold War levels,” Kofman told The National Interest. “That's frankly impossible.  How can one-fifth the submarine force of the Soviet Union, with barely 50 percent operational readiness - and I think that's very generous - could be operating at a level of activity of what was the largest submarine force in the world?”

Meanwhile, on the other side of the world, the Chinese People’s Liberation Army Navy (PLAN) has more than 70 submarines and is rapidly expanding. However, the quality of Chinese submarines lags behind qualitatively compared to American or Russian boats—though Hendrix has contended that the newest Type 093B and forthcoming Type 095 submarines offer acoustical performance comparable to the U.S. Navy’s Improved Los Angeles-class boats. The Chinese have “at least 70, and they’re building,” Vice Adm. Joseph Mulloy, the U.S. Navy’s deputy chief of naval operations for integration of capabilities and resources told the House Armed Services Committee’s seapower and projection forces subcommittee on February 25.  “You get back into the whole quality versus quantity issue, but at the same time the Russians are also building...and they build much higher-end submarines.”
