Survivability assessments and vulnerability reductions are required in warship design. A warship’s survivability is assessed by itssusceptibility, vulnerability, and recoverability. In this paper, an integrated survivability assessment for a warship subjected to multiple hits isintroduced. The methodology aims at integrating a survivability assessment into an early stage of warship design. The hull surface is idealizedusing typical geometries for RCS (Radar Cross Section) detection probability and susceptibility. The Vulnerability is evaluated by using theshot-line. The recoverability is estimated using a survival time analysis. This enables the variation of survivability to be assessed. Several parametersmay be varied to determine their effects on the survivability. The susceptibility is assessed by the probability of detecting the radar cross section ofthe subject and the probability of being hit based on a probability density function. The vulnerability is assessed by the kill probability based on thevulnerable area of critical components, according to the component’s layout and redundancy. Recoverability is assessed by the recovery time fordamaged critical components.
