Jammers are an unconventional aircraft class that have the exclusive capability of using ECM or ESM. They were introduced in Ace Combat 5: The Unsung War along with the Special Weapon ECM. Jammers are generally modified versions of their original aircraft. The EA-6B Prowler for example is the jammer version of the A-6E Intruder. The job of the jammer is to support their allies and weaken their enemies capabilities using electronic warfare. They are generally hidden or escorted in missions but radar jamming and abnormal numbers of enemies give away that they are there. In Ace Combat Zero: The Belkan War and Ace Combat 6: Fires of Liberation, enemy jammers could blanket a portion of the radar within their radius giving their side a tactical advantage. Players and wingmen however, could not do this, but instead deflect missiles for their whole squadron.
Jammers were first used in Blind Spot by the Yuktobanian forces retreating from the area. Jammers eventually returned to their original aircraft role and in Ace Combat Infinity most of them became multiroles.
