THREATS BY SURVIVABILITY CLASSIFICATION
To credibly assess the threat a UA will face one must consider the entire system, including the ground
station and data link as well as the aircraft. One must also consider the entire spectrum of threat types,
including directed energy weapons (DEW) and nuclear, biological and chemical (NBC). A basis for
starting a general threat analysis is to consider the types of threats and the likelihood each could engage
each UA category Tables K-1 and K-2). For a detailed threat analysis, a UA must be assessed
individually based on its specific design, mission, and mode of operation.

SURVIVABILITY DESIGN FEATURES BY SURVIVABILITY CATEGORY
Survivability design features should be considered with respect to an UA’s size, required mission and the
potential threat environment. Table K-3 is a partial list of potential survivability features and the class of
platform they may be most applicable to. The features cover both susceptibility reduction and
vulnerability reduction. These potential survivability design features should be considered in the systems
engineering design process to develop the most effective UA for the lowest life cycle cost.
