Editing Electronic countermeasure (section)

== History ==
The first example of electronic countermeasures being applied in a combat situation took place during the [[Russo-Japanese war]]. On July 13, 1904, Russian [[wireless telegraphy]] stations installed in the [[Lüshunkou|Port Arthur]] fortress and on board Russian light cruisers successfully interrupted wireless communication between a group of Japanese battleships. The spark-gap transmitters in the Russian stations generated senseless noise while the Japanese were making attempts to coordinate their efforts in the bombing of a Russian naval base.  [[Germany]] and [[United Kingdom]] interfered with enemy communications along the western front during [[World War I]] while the [[Royal Navy]] tried to intercept German naval radio transmissions.<ref name="proceedings">Polmar (1979), p. 121.</ref>  There were also efforts at sending false radio signals, having shore stations send transmissions using ships' call signs, and jamming enemy radio signals.<ref name="proceedings" /> On the other hand, there were also attempts by the Ottoman side to jam Allied wireless communications during the [[Gallipoli campaign]].<ref>{{cite book | language = tr | title = Tevfik Rıza Bey | url = https://canakkalesavaslariansiklopedisi.com/content/tevfik-riza-bey/ | author = Vahibe Türkan Doğruöz | access-date=6 December 2023 | publisher = Çanakkale Savaşları Ansiklopedisi | year = 2022 | isbn = 978-605-80897-7-8}}</ref>

[[World War II]] ECM expanded to include dropping [[Chaff (countermeasure)|chaff]] (originally called Window), jamming and spoofing radar and navigation signals.<ref name="proceedings" /> German bomber aircraft navigated using radio signals transmitted from ground stations, which the British disrupted with spoofed signals in the [[Battle of the Beams]]. During the RAF's night attacks on Germany the extent of electronic countermeasures was much expanded, and a specialised organisation, [[No. 100 Group RAF]], was formed to counter the increasing German [[night fighter]] force and radar defences. [[Cold War]] developments included [[anti-radiation missile]]s designed to home in on enemy radar transmitters.<ref name="proceedings" />

In the 2007 [[Operation Orchard]] Israeli attack on a suspected Syrian nuclear weapons site, the [[Israel Air Force]] used electronic warfare to take control of Syrian airspace prior to the attack.<ref>{{Cite news |title=And they struck them with blindness |author=Yaakov Katz |work=The Jerusalem Post |date=2010-09-29 |access-date=2025-03-16 |url= https://www.jpost.com/Magazine/Features/And-they-struck-them-with-blindness}}</ref> Israeli electronic warfare (EW) systems took over Syria's air defense systems, feeding them a false sky-picture while Israel Air Force jets crossed much of Syria, bombed their targets and returned.<ref>[http://aviationweek.com/awin/israel-shows-electronic-prowess Israel Shows Electronic Prowess] Nov 26, 2007, David A.
