Electronic Countermeasure

An ECMP (Electromagnetic Counter Measure Pod) is a device used to 'jam' radar and prevent it from locking onto targets. Aircraft such as the EA-6B Prowler are used for this role. However, fictional Ace Combat aircraft such as the ADFX-01/02 Morgan and the CFA-44 Nosferatu are able to carry this device internally. The jammer emits electromagnetic pulses that can scramble radar. Most usually jammer aircraft are highly specialized, like EA-6B Prowler, EA-18G Growler, EA-200 and the E-767 AWACS planes in the AC series, or the Tornado GR.4 in Ace Combat 6. The CFA-44 and ADFX-01 are single-seat aircraft and seem to have greatly reduced the difficulty of operating a jammer.

In-game in Ace Combat 04:Shattered Skies the aerial transport attack mission (against three C-17A Globemaster IIIs) is complicated by a pair of E-767 jammer aircraft that produce a solid green circle overlapping all planes underneath their radar cover, but do not impede "naked eye" viewing or missile targeting. In Ace Combat 5: The Unsung War, a similar mission has the 3 E-767 AWACS jammers create visual "fakes" with intent to cause missiles to be wasted against them. In Ace Combat 6: Fires Of Liberation , enemy ESM-generating (and thus missile accuracy-degrading) objects presumably have some form of ECMP installed, and there is at least one mission where enemy Tornado GR.4 planes are acting as mobile jammers by continuously using ECMPs.
