The Compass Call system employs offensive counter-information and electronic attack (or EA) capabilities in support of U.S. and Coalition tactical air, surface, and special operations forces. The EC-130H, EA-6B or EA-18G, and F-16CJ, form the Suppression of Enemy Air Defense (SEAD) triad. Programmed upgrades have expanded its mission by procuring a secondary EA capability against early warning and acquisition radars.
Note how the EA-18G Growler is one third of the SEAD triad.
Meaning, it has specific roles/capabilities not found in the F-16CJ or the EC-130H and vice versa. Likewise, note how the EC-130 performs certain missions that you wouldn't normally think of as electronic attack.
So r we going for LM 130H,F16CJ, Growler SEAD Triad? A dedicated EW Command compromising SEAD+DEAD?
