What is the expected threat? How do you intend to respond to an intrusion? How long will it take you to do so? These factors determine the size of the area that must be surveilled Most Important Factors in Designing System
Mine Threat • Mines are the most cost effective method of conducting naval warfare. • Low cost to produce • Low risk to install • Expensive and time consuming to remove. • A more serious threat than generally realized • On the sea-floor near choke points • Delivered by mini-subs or Swimmer Delivery Vehicles • Affixed to the hull of innocent vessels
Enormous Economic Impact It’s been estimated that an attack that shuts down the Port of Long Beach or LA would cost the US economy >$1,500,000,000/day • Sinking a vessel in a choke point is not that hard to do • Limpet Mines on the Vessel • Solution is Hull Scanning • Proximity Mines on the Sea Floor • Solution is Q Routing
