China is making waves with the recent launch of what could be its most advanced diesel-electric submarine yet, adding a significant asset to its ever-growing undersea fleet. While official announcements from Beijing's defense ministry or navy remain conspicuously absent, the news hasn't gone unnoticed. The buzz started when Naval News broke the story, revealing that this new submarine might be a fresh variant of the already formidable Type 039A/B/C, also recognized under NATO's classification as the Yuan-class.
A Silent Launch with Massive Implications
The submarine's launch in April was shrouded in mystery, quietly taking place at the Wuchang shipyard in central China. It wasn’t until July that it was spotted by Tom Shugart, a former U.S. Navy submariner turned defense analyst. Shugart noticed something unusual—the submarine seemed to have an x-shaped stern, a design feature he claimed he had "not seen before on any Chinese submarine." This detail alone sparked considerable interest and speculation among naval experts worldwide.
Adding to the intrigue, H.I. Sutton, a maritime security analyst well-versed in the intricacies of naval architecture, noted some striking similarities and differences between the new submarine and its predecessors. Sutton pointed out that the forward section of the submarine bore a close resemblance to the existing Yuan-class variants in terms of its proportions, particularly in areas where sonar and torpedo functions are critical. However, what set this submarine apart was its hull, especially the section behind the sail, which appeared "significantly longer." This design tweak could be a game-changer, potentially indicating the inclusion of a Vertical Launch System (VLS)—a feature not present in earlier Yuan-class models.
The Power of VLS: A Game-Changer
For those not in the know, a VLS is a big deal in naval warfare. Typically found on surface warships and nuclear-powered submarines, a VLS allows these vessels to carry a variety of missiles suited for different missions. This versatility is invaluable, especially in modern warfare, where the ability to adapt to changing circumstances can be the difference between victory and defeat. However, incorporating VLS into diesel-electric submarines, which are generally smaller than their nuclear-powered counterparts, is a rare and innovative move.
If the new Chinese submarine indeed has a VLS, it could carry between four and eight cells, each housing a missile. These missiles could potentially include anti-ship ballistic missiles or land-attack cruise missiles—types that are too large to be fired from conventional torpedo tubes. This would represent a significant upgrade in the firepower of China's diesel-electric submarine fleet, enabling them to engage a wider range of targets with greater precision and from longer distances.
The Bigger Picture: China’s Expanding Submarine Fleet
This latest development fits into a broader pattern of China's relentless expansion of its submarine force. According to a report released by the U.S. Department of Defense last year, the Chinese Navy currently operates 48 diesel-electric-powered submarines. Of these, nearly half—21 to be exact—are Type 039A/B variants, each displacing around 3,600 tons. The most recent variant, the Type 039C, is noted for its stealthy sail design, which helps reduce its detectability in the open ocean.
But China isn't just content with maintaining its current fleet. The Pentagon's report forecasts that China's submarine force will swell to 65 units by 2025 and could reach an impressive 80 units by 2035. This expansion includes not only diesel-electric submarines but also an increase in nuclear-powered submarines. Currently, China operates six nuclear-powered ballistic missile submarines and six nuclear-powered attack submarines, further underscoring its commitment to enhancing its naval capabilities.
A Rising Power: What This Means for Global Naval Dynamics
China's aggressive submarine buildup is a clear signal of its ambitions to become a dominant maritime power. This is particularly evident when you compare China's approach to that of the United States. All U.S. Navy submarines, whether they are ballistic missile submarines or attack submarines, are powered by nuclear reactors. This gives them a distinct advantage in terms of endurance and range, as they can remain submerged for much longer periods than diesel-electric submarines.
One of the U.S. Navy's most advanced submarines, the USS Minnesota—a Virginia-class attack submarine—is set to forward-deploy to Guam in the upcoming fiscal year, starting October 1. This deployment is a strategic move, placing a top-tier U.S. submarine closer to the increasingly contested waters of the Asia-Pacific region. It's a clear response to China's growing naval prowess, which includes not only its expanding submarine fleet but also its broader military modernization efforts.
The Strategic Implications: A New Era of Undersea Warfare
The introduction of this new submarine variant could have far-reaching implications for the balance of power in the Asia-Pacific region. China's ability to produce and deploy advanced diesel-electric submarines equipped with VLS could alter the strategic calculus for both regional powers and the United States. These submarines, potentially armed with advanced anti-ship and land-attack missiles, would enhance China's ability to project power and influence across the region.
Moreover, the stealth capabilities of these submarines, combined with their missile-carrying potential, would make them formidable adversaries in any naval conflict. The possibility of these submarines operating undetected in contested waters, launching surprise missile strikes against surface ships or land targets, adds a new layer of complexity to naval warfare in the region.
Conclusion: The Undersea Arms Race is Heating Up
China's launch of this new diesel-electric submarine underscores the ongoing undersea arms race that is quietly but steadily escalating. As China continues to expand and modernize its submarine fleet, it is clear that it aims to challenge the maritime dominance of the United States and its allies. The introduction of advanced features like VLS in diesel-electric submarines is just one example of how China is pushing the envelope in naval technology and strategy.
For the U.S. and other regional powers, this development is a wake-up call. It highlights the need for continued vigilance and investment in undersea warfare capabilities. As the undersea domain becomes an increasingly contested space, the ability to detect, track, and neutralize these advanced submarines will be crucial in maintaining a balance of power in the Asia-Pacific region. The stakes are high, and the undersea battlefield is set to become one of the most critical arenas in the ongoing competition between great powers.
