The main difference between SH-60B and F is the way they fight against submarines. The B version mainly depends on the sonars on the CG and DDGs to find the targets, then it flies to the suspect area, using 25 tubes sonar buoyages and magnetism detector to make sure the target position for following combat using torpedo. The F is used for short range anti-submarine purpose around the carrier and depends on its own AQS-13F suspensory sonar to detect the submarine.

SH-60B和F型之间的主要区别为他们反潜的方法不同。B型主要依赖巡洋舰和驱逐舰上的声纳发现敌潜艇，然后飞近可疑区域，使用其25管的声纳浮标和磁异常探测器对目标精确定位，随后发起鱼雷攻击。F型则用于航母周围的短距反潜，主要依赖其AQS-13F悬吊声纳探测雷达。
