Abstract

A decision support and control system including a Graphical User Interface configured for displaying multiple transit options for a platform with respect to hazard and objects along with accompanying methods is provided. The methods and apparatus may receive information from a variety of systems such as a ship'"'"'s radar and electro-optical systems to derive threat information, and a ship'"'"'s weapon systems that may include both lethal and non-lethal weapons, the maximum and minimum range of the weapons, the accuracy characteristics of the weapons, and the maximum and minimum azimuth angles that the weapons can engage. The apparatus and methods may provide multiple transit options for a ship that provides tactical suggestions for a ship to successfully defend itself against a swarm attack by multiple incoming threats. Such tactical suggestions illustratively account for the various paths being presented and may also present performance metrics such as associated probabilities of success.
