反潜巡逻机的特点是能够携带多种探潜设备和攻潜武器,且搜索面积大,留空时间长。而反潜直升机的最大特点是机动灵活。它可以低空悬停在海面使用主动吊放声呐探测水下潜艇,可以在低空低速飞行状态下保持对水下潜艇的连续跟踪,因此特别适合于搭载舰艇使用,在编队附近易受舰艇噪声干扰的区域内进行反潜作战。但无论是哪一种反潜机,要打击潜艇,前提是首先要能发现 Anti-submarine patrol aircraft is characterized by the ability to carry a variety of potential equipment and attack the submarine weapons, and the search area, leave a long time. The most prominent feature of anti-submarine helicopters is flexible. It can hover over the sea at low altitude. It can detect the underwater submarine by using the active submarine sonar. It can keep continuous tracking of the underwater submarine at low altitude and low speed. Therefore, it is especially suitable for the use of the ship and is easily disturbed by the ship noise in the vicinity of the formation Anti-submarine warfare within the region. But no matter what kind of anti-submarine aircraft, to combat submarines, the premise is to be found first
