mine countermeasures (MCM): ASuW armament consists of the M197 20mm rotary cannon and launch tubes that expel exhaust downward between the struts of the SWATH hulls, concealing and dissipating the thermal signature of the launch for BGM-176B Griffin missiles and Advanced Precision Kill Weapon System rockets, with an electro-optical/infrared (EO/IR) sensor and radar. An ASW version could be equipped with an EO/IR sensor, radar, sonobuoy launch tubes, a dipping sonar, and four aft-firing torpedo tubes; an MCM version could be equipped with a towing boom to lower and raise two towed mine-hunting sonars, such as the Kline 5000 or Raytheon AN/AQS-20A. The current Ghost costs $10 million per copy, is crewed by 3-5 sailors, has an endurance of 3 days, and can be partially disassembled to fit in a Boeing C-17 Globemaster III for transport if needed. There is room for 16 passengers with two - diameter round windows in the hull. It is designed for fleet protection for navies with few blue-water needs but require a small and affordable craft in large numbers for near-shore maritime border patrol and defense missions.
