Capturing or impeding traditional or supercavitating torpedoes from striking a side or entering the keel area of a capital ship depends on very precise tracking. Because supercavitating torpedoes travel at about 550 miles/hr, even milliseconds will be vital, perhaps causing a countermeasure weapon, like a supercavitating cannon shell, to disrupt its cavitation but not impeding its slower motion toward the ship. Likewise, capture curtain soft-kill defense allows not one second to be squandered because of inaccurate tracking. One purpose of the invention is to scatter, in and around the roughly calculated path of the torpedo, tiny, inexpensive balls that have sonar, magnetometers and other active and passive sensors to aid Fire Control predicting arrival time and where it will strike. Over time, smaller swarms of measurement balls are continually launched as tracking precision improves. Countermeasures are constantly updated by Fire Control. A second use aids a helicopter that acquired a super quiet submarine; it can initially launch a wide swarm of sensors in the sub's area, and they will continually monitor the movement. As location becomes more precise, smaller swarms are launched in sequence. If the sub dives for safe layers, the swarm detaches the sonar ball and they will sink slowly, using sonar and sending location pinging messages to Fire Control.
