Integrated Survivability analysis of naval platforms incorporates the domains of susceptibility, vulnerability and recoverability, measured temporally. These are accepted as key elements when holistically assessing naval platform survivability against threat scenarios. Conversely, traditional naval platform survivability assessment only considered the vulnerability domain or a combination of susceptibility and vulnerability. However, emphasis is now placed on the interdependence of susceptibility, vulnerability and recoverability. Unfortunately, there are shortcomings with historic survivability modelling and assessment capabilities pertaining to Integrated Survivability. This has resulted in the need to clearly define the concept of Integrated Survivability, and identify modelling requirements to assess platforms exposed to the threat environments. A naval platform Integrated Survivability assessment capability, derived from those survivability modelling requirements, will enable naval architects and mission planners to quantify the effects of platform survivability. Assessments will consider platform safety systems and survivability control measures, and changes to those systems and control measures. Outcomes from the assessments will contribute to platform configuration optimisation for resilience against the threat environment and enable mission success. This paper presents the need for an Integrated Survivability assessment capability, defining relevant terminology, and elucidating modelling requirements to develop such a capability. • Differentiates capability survivability and platform Integrated Survivability. • Integrated Survivability is not a static concept. • Defines Integrated Survivability of naval platforms as a temporal concept. • Identifies modelling and simulation techiques, including Digital Twin, to quantify Integrated Survivability. • Proposes a simulation capability to assess Integrated Survivability.
