In the military environment, survivability is defined as the ability to remain mission capable after a single engagement. Survivability comprises three elements:
* Susceptibility - the likelihood of being detected, identified, and hit
* Vulnerability - the effects of being hit by a weapon
* Recoverability - longer term post hit effects, damage control and firefighting, capability restoration or (in extremis) escape and evacuation.
The European Survivability Workshop introduced the concept of "Mission Survivability" whilst retaining the three core areas above, either pertaining to the "survivability" of a platform through a complete mission, or the "survivability" of the mission itself (i.e. probability of mission success). Recent studies have also introduced the concept of "Force Survivability" which relates to the ability of a force rather than an individual platform to remain "mission capable".
There is no clear prioritisation of the three elements; this will depend on the characteristics and role of the platform. Some platform types, such as submarines, minimise their susceptibility and may to some extent compromise in the other areas. Main Battle Tanks minimise vulnerability through the use of heavy armours. Surface warship designs tend to aim for a balanced combination of all three areas.
