The task of locating a cooperative submarine, equipped with locator aids, is compared to that of locating a noncooperative submarine. It is shown that, if a cooperative search can be undertaken, the search and location operation is not the critical time segment of the rescue mission. If a noncooperative search must be undertaken, search and location becomes the critical time element. The most useful locator aid is found to be the underwater telephone, with which all submersibles are equipped. A generalized mathematical treatment is given, where the characteristics of the search equipment, the search vehicle, and the environment are treated in parametric form, along with the uncertainty in the location of the distressed submersible DISSUB. Parametric analysis is applied to obtain realistic performance predictions. For the cooperative search, results are presented in the form of location time vs. range to the distressed submersible. For the noncooperative search, the results are presented in the form of curves of time to locate vs. probability of success.
