Hardpoint: Electronic Countermeasures in Ace Combat

Updated: Sep 3, 2021

Within the Ace Combat series advanced forms of electronic countermeasures (ECM) has exclusively been a non-player character (NPC) feature since it was first introduced. NPC ECM is commonly deployed by enemy forces in an effort to increase the difficulty of single player missions. Electronic countermeasure support is not usually deployed in favor of the player or their allies. ​


Though the presence of ECM cannot be specifically confirmed in Air Combat (1992/1995), mission 6 of Ace Combat 2 (1997) is the first mission to introduce electronic countermeasures within its briefing. A pair of E-767 Vigilante AWACS aircraft disrupted or "jammed" the player's radar, making it harder for them to track the enemy units using their radar. By hindering radar detection from all ranges, it forced the player to rely more on small pieces of information they could glean through breaks in the enemy jamming. ​​ ​ ​​​From Ace Combat 2 to the release of Ace Combat Infinity (2014), NPC ECM would become a reoccurring factor in a limited amount of missions for Ace Combat releases on PlayStation 1, 2, 3, PlayStation Portable, Nintendo DS and Xbox 360. As the series advanced in regards to graphics and game mechanics so too did ECM. The basic forms of NPC electronic countermeasures are primarily focused on disruption of navigation systems and communications. More advanced types of ECM are capable of tricking and denying player controlled weapons systems. Often times enemy NPC units will use multiple types of ECM at once to effectively disrupt the player.

​In Ace Combat 5 Electronic Counter-Countermeasures (ECCM) were also introduced but was closely tied to the plot of the story. It wasn't used much outside of in game plot points which used ECM interference to drive the story forward. As such, allied ECCM wasn't really a factor in game play. A second form of ECM is enemy deployed Electronic Support Measures (ESM). ESM acts differently than ECM in a few different ways, but ESM that is deployed by enemy forces reduces the homing performance of missiles fired by the player or their allies while they operate within enemy ESM range. In that sense, it is a electronic countermeasure.



NPC ECM Platforms


The electronic countermeasure platforms used by non-player character allies and enemies are usually aircraft or land-based installations.


Aircraft are the most common ECM platform used. NPCs frequently use known military electronic jammer aircraft like the Su-24MP, EA-18G, Tornado ECR, along with larger aircraft like E-767 Vigilante, IL-76 and similar platforms.


Land based jammers come from specific types of radar vehicles or military installations. Certain notable super weapons like the Excalibur Anti-Ballistic Missile System and Stonehenge Spaceguard Turret Network utilizes electronic counter measures to ward off attacks from close and long ranges.



Types of ECM

Communications Jamming

Experienced in single player missions, frequently used in plot related events. Communication between in game allies is disrupted by ECM causing confusion. Static on the radio and missing words within subtitles are common characteristics.





Decoy Projection

​False targets appear on the player’s heads up display and radar. This type of ECM can lead to the waste of mid and long ranged special weapons fire. Visually identifying targets before firing in necessary. By closing into visual range or using the in-game camera to zoom, the actual target can be located.



Radar Suppression Jamming that blocks out radar. Its severity can range from the disruption of localized areas to complete radar black out in the mission area. The most common visualization of radar suppression appears as a green circle which emits waves of interference at varying intervals of time. The design of the green circle varies in each Ace Combat game.


Weapons System Jamming

This type of ECM is designed to deny the guidance capabilities, causing guided weaponry to lose lock mid-flight and disabling the heads up display so it cannot show the position of enemy units. The visual effect of weapons system jamming includes scan lines on the HUD and the disappearance of all enemy target indicators for varying periods of time. 




Notable Uses in Ace Combat Series

ADFX-02 Morgan.

​Morganite ECM System

The ADFX-02 Morgan, constructed by the South Belkan Munitions Factory before the events of Ace Combat Zero: The Belkan War, featured a set of highly specialized weapons. Among them was the Morganite ECM system which was powerful enough to physically deflect incoming missile and gunfire from any angle and any range. The only weak point was its inability to cover the area around the ADFX's engine intakes. This meant that the only way to shoot down the Morgan was to fire at it from its direct front. From the point of view of game design, it's clear that the Morganite ECM system was created to enable
