Suppression of the infrared signature of tanks helps increase their survivability. Signature control can be accomplished with a variety of methods such as obscuration, surface appliques, shape tailoring, active cooling and integrated designs. In addition to infrared, the technique chosen must be compatible with signature control in other bands especially the radio frequency(RF) band. Obscuration and the application of low emissivity paint are the primary measures of infrared signa ture control for tanks being in service. The integrated designs, however, are the most economical, operationally useful, and long lasting signature control solutions for future tanks.
