中國093B核潛艇靜音技術堪比美軍 數量是美國2倍.

美國20160627日稱，中國新型093B核動力攻擊潛艇比得過美國海軍“洛杉磯”級改進型潛艇嗎？

至少一些美國海軍分析人士相信比得過，他們認為，中國人民解放軍海軍的新式潛艇是北京迅速趕上西方的標誌。雖然“海狼”級和“佛吉尼亞”級潛艇是美國海軍的主要攻擊潛艇已經超越了改進型“洛杉磯”級潛艇，但這種陳舊的潛艇在很長時間內還是會是美國軍方水下艦隊中的主力艇型。如果中國海軍的最新潛艇與美國海軍規模不斷縮小的水下編隊的能力相當，華盛頓的麻煩就大了。

這款潛艇的靜音效果更好，可搭載各種各樣的武器系統，包括巡航導彈和垂直發射系統。093B型潛艇與‘洛杉磯’改進型潛艇在靜音技術方面旗鼓相當，它們的出現證明中國正在學習如何建造一艘現代化的快速攻擊潛艇。”

北京一直在升級、擴充潛艇編隊，將會有4艘‘商’級（093型）潛艇列裝部隊，加入到原有的2艘之中。‘商’級潛艇將會淘汰老舊的‘漢’級潛艇（091型）。經過改進的‘商’級潛艇擁有垂直發射系統，可發射先進的鷹擊-18反艦巡航導彈。未來十年內，中國可能會建造095型核動力巡航導彈攻擊艇，這不僅能提升中國海軍的反水面戰能力，還能讓其更隱秘地參與登陸作戰。

Why the US Navy Should Fear China's New 093B Nuclear Attack Submarine.

China’s new Type 093B nuclear-powered attack submarine on par with the U.S. Navy’s Improved Los Angeles-class boats?

At least some U.S. naval analysts believe so and contend that the introduction of the new People’s Liberation Army Navy (PLAN) submarines is an indication of just how quickly Beijing is catching up to the West.

“The 93B is not to be confused with the 93. It is a transition platform between the 93 and the forthcoming 95,” said Jerry Hendrix, director of the Defense Strategies and Assessments Program at the Center for a New American Security—who is also a former U.S. Navy Captain. “It is quieter and it has a new assortment of weapons to include cruise missiles and a vertical launch capability. The 93B is analogous to our LA improved in quietness and their appearance demonstrates that China is learning quickly about how to build a modern fast attack boat.”

Other sources were not convinced that Beijing could have made such enormous technological strides so quickly—but they noted that the topic of Chinese undersea warfare capability is very classified. Open source analysis is often extremely difficult, if not impossible. “Regarding the question on the Type 093B, I really don’t know, anything is possible I suppose, but I doubt it,” said retired Rear Adm. Mike McDevitt, now an analyst at CNA’s Center for Naval Analyses. “I have no doubt that the PLAN has ambitions to at least achieve that level of capability and quietness.”

Though the Seawolf and Virginia-classes have surpassed the Improved Los Angeles-class as the premier U.S. Navy attack submarines, such older vessels will remain the mainstay of the service’s undersea fleet for many years to come. If the People’s Liberation Army Navy’s newest boats are able to match the capabilities of the U.S. Navy’s shrinking undersea fleet, Washington could be in serious trouble. Indeed, the U.S. Navy already anticipated that it could be facing-off against a Chinese submarine fleet that is nearly twice its size, but not as technically capable.

The U.S. Navy—which has roughly 52 attack submarines—is on track to have 41 attack boats by 2029. The Chinese, meanwhile would have “at least 70, and they’re building,” Vice Adm. Joseph Mulloy, the service’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.”

In a 2016 report to Congress, the Pentagon noted that Beijing continues to upgrade and expand its submarine fleet: “China continues to improve its SSN force, and four additional SHANG-class SSN (Type 093) will eventually join the two already in service. The SHANG SSN will replace the aging HAN class SSN (Type 091). These improved SHANG SSNs feature a vertical launch system (VLS) and may be able to fire the YJ-18 advanced anti-ship cruise missile (ASCM). Over the next decade, China may construct a new Type 095 nuclear-powered, guided missile attack submarine (SSGN), which not only would improve the PLAN’s anti-surface warfare capability but might also provide it with a more clandestine land-attack option.”

The problem, however, is if Hendrix’s assessment is correct and future Chinese submarines are only slightly less capable than the Virginia or Seawolf-class vessels, the Navy could be in trouble. The technological edge the U.S. Navy—which is already woefully short on attack boats—is counting on might not be sufficient to counter Chinese numerical superiority. However, the service is continuing to improve the performance capabilities of its submarines on a continual basis. Nonetheless, one former U.S. Navy undersea warfare officer suggested that the service would come to regret having truncated the high-performance submarine-hunting Seawolf-class at three boats and focusing instead on the more multi-role Virginia-class.
