Threat densities expected on a modern battlefield do not allow penetrating tactical aircraft the option of simply flying around individual threats. As the threat becomes even more sophisticated in the 1990s new aircraft avionic systems will need to be fielded that will enable survivable penetration of tactical aircraft in an even more lethal threat environment. Recent advances in onboard mission planning, navigation, and terrain following/terrain avoidance/threat avoidance (TF/TA/TA) technologies and the onboard availability of stored digital terrain data enable the mechanization of such a survivable penetration capability. Onboard mission planning constructs a survivable penetration reference corridor which takes into account terrain data, the location of known threats, the expected densities of unknown and mobile threats, and mission goals. An advanced aided navigation capability, using information from the global positioning system, aiding sensors such as radar, and terrain navigation features, is necessary to make maximum use of the onboard terrain data. The TF/TA/TA function computes flyable three-dimensional paths within the reference corridor accounting for aircraft performance limits, knowledge of the surrounding terrain, and information about the threat. All three technologies use the Defense Mapping Agency's Digital Land Mass System (DLMS) terrain to provide look-ahead terrain masking and aided navigation. Through this survivable penetration methodology, advanced tactical aircraft can have enhanced aircraft survivability.
