SSN-21 Seawolf-class
SSN-21 海狼級核動力攻擊潛艇
原文 :
Seawolf-class submarines were designed to operate autonomously against the world's most capable submarine and surface threats. The primary mission of the Seawolf was to destroy Soviet ballistic missile submariness before they could attack American targets. The Soviet submarines are one of the most survivable elements of their intercontinental ballistic missile arsenal. In addition to their capabilities in countering enemy submarines and surface shipping, Seawolf submarines are suited for battlespace-preparation roles. Incorporation of sophisticated electronics produces enhanced indications and warning, surveillance, and communications capabilities. These platforms are capable of integrating into a battle group's infrastructure, or shifting rapidly into a land-battle support role.
The Seawolf features a strengthened sail, designed to permit operations under the polar ice cap for taking the fight to the Soviets in their own front yard. It sports an eight-tube, double-deck torpedo room to simultaneously engage multiple threats. It incorporates the latest in quieting technology to keep pace with the threat then posed by an aggressive Soviet Union.
The Seawolf has the highest tactical speed of any US submarine. Much much of the design effort was focused on noise reduction, and it is expected that the fully coated boat will restore the level of acoustic advantage which the US Navy enjoyed for the last three decades. The Seawolf's propulsion system makes it ten times more quiet over its full range of operating speeds than the Improved-688 class and 70 times more quiet than the initial generation of Los Angeles 688-class submarines. The Seawolf's quieter propulsion system will also enable it to have twice the tactical speed as the I-688. Tactical speed is the speed at which a submarine is still quiet enough to remain undetected while tracking enemy submarines effectively. Overall, the Seawolf's propulsion system represents a 75-percent improvement over the I-688's -- the Seawolf can operate 75 percent faster before being detected. It is said that SEAWOLF is quieter at its tactical speed of 25 knots than a LOS ANGELES-class submarine at pierside. |
