目前,美国潜艇在安静性方面处于世界领先水平,它们长期游弋在大洋中,对环境产生微小的热力、磁力以及水压场的扰动,要在深海中探测到这些水下游猎者是非常困难的。尽管如此,美国潜艇现在又要而对诸多新的挑战和问题。首先,新的海军战略要求潜艇能适应近海浅水域的作战环境,像波斯湾等,从声场传播的角度来着,在近海浅水域保持潜艇的安静性是非常困难的。其次,随着信号处理技术、声纳技术、计算机技术和通信技术的快速发展,使各国的反潜探测能力大大提高,这就要求潜艇进一步降低噪声水平。最后,美国军费紧缩政策迫使美国海军在努力提高潜艇安静性的同时不得 At present, the submarines of the United States are at the leading position in terms of quietness. Due to their long cruising in the oceans, the submarine submarines have little thermal, magnetic and hydrostatic field perturbations. It is very difficult to detect these underwater hunters in the deep sea . In spite of this, the U.S. submarine now has yet to face many new challenges and problems. First of all, the new naval strategy requires submarines to adapt to the operational environment of shallow waters in the coastal waters. For example, in the Persian Gulf, it is very difficult to maintain the submarine quietness in shallow waters of the coastal waters from the perspective of sound field transmission. Secondly, with the rapid development of signal processing technology, sonar technology, computer technology and communication technology, the anti-submarine detection capability of all countries is greatly enhanced, which requires the submarine to further reduce the noise level. Finally, the U.S. military austerity policy has forced the U.S. Navy not to work hard to improve the quietness of the submarine at the same time
