The US Navy currently has a capability in gap pressure mine sweeping. The Navy historically does not have adequate means to remotely pressure-sweep for mines at reasonable speeds and cost. These threats are addressed by the Navy, but countermeasures are time consuming and resource intensive. FTL personnel, in collaboration with the Naval Postgraduate School (NPS), has developed a revolutionary solution employing a towed body that emits a dense trail of bubbles at moderate depth. The resulting bubble trail persists, rising in the water column long after the towed body moves on, creating a pressure signature equivalent to that of a passing target hull for activating pressure-sensitive mines.
