The survivability of the warship is defined as the capability of a warship to avoid or withstand a man-made hostile environment. The survivability of the warship consists of three categories (Susceptibility, Vulnerability and Recoverability). A warship performance in susceptibility terms is measured by the probability of detection, and probability of hit. So, the level of susceptibility of a warship in encounter with threat is dependent upon attributes for detection equipment and weapon system. This paper has described the theoretical procedure for the susceptibility assessment. And, the theoretical background which is suggested to assess the susceptibility of a warship is based on the simplified probabilistic theory. The main emphasis of this paper would be on simplified calculation model based on the probability density function for probability of hit. It implements assessment of the probability of hit given a both singlehit and multiple-hit. The susceptibility is accessed for a RCS (Radar Cross Section) and the hit probability for a rectangular target is applied for a given threat.
