Editing ECM

[[File: Imperial Sunburst-Sun-IISS-Traveller.gif|right]]
[[ECM]] is an acronym standing for Electronic Countermeasure.
* It is a type of [[Ship Equipment]].
* It is part of [[Electronic Warfare]]

== Description (Specifications) ==
An electronic countermeasure (ECM) is a device designed to trick, deceive or overwhelm a [[Ship Sensor Suite|sensor]] system in order to deny information to an enemy. Electronic countermeasures are frequently coupled with [[EMM|stealth technology]] and other passive defensive systems.
* A variety of ECM devices, capable of countering a range of [[Ship Sensor Suite|sensors]] and detectors and grouped together into a single unit, are referred to as an ECM package.
* ECM may itself be defeated, overwhelmed or overcome by [[ECCM|electronic counter-countermeasures]] ([[ECCM]]).

ECM may be used in both a Passive and an Active role.
* Passive ECM can give false sensor readings or help to mask signatures.
* Active ECM often takes the form of "jamming", or overwhelming an enemies sensors with signals and noise.

== History & Background (Dossier) ==
ECM is generally available from [[TL-6]] onwards, becoming more powerful, more efficient and more compact as the technology improves.
