MEZ PEN P MEZ Stand-In Offensive EA P P P A V ALTITUDE Stand-Off Offensive EA SAM RANGE did not include the EF-111A in the StandOff list because it was also capable of stand-in and escort mission roles, albeit in a pre-2000s IADS.) All are manned assets reaching into the IADS from the midcourt and backcourt to maintain EA on the strike package(s) and suppress from a distance. A stand-off asset's self-defense capability and the threat's home-on-jam capability drive standoff distance. In turn, distance often drives higher power jamming requirements and can result in larger burn-through ranges and slower re-alignment rates (as indicated in blue, in Figure 1). Conversely, stand-in jamming assets are (against a modern adversary IADS) typically unmanned, dispensable offensive EA assets designed to attack an IADS inside the MEZ - requiring lower power - and operate in a higher threat environment. The strengths of a stand-off jammer are high power and thinking aircrew able to respond to unplanned/unpredicted threat actions. The weakness of a stand-off jammer is its dependence on another asset to provide protection against an air threat while conducting its EA/SEAD mission. The strengths of a stand-in jammer are that it is dispensable, it can be put into harm's way without affecting the Commander's ac- The Journal of Electronic Defense | May 2014 Figure 2.
