Electromagnetic warfare or electronic warfare (EW) is warfare involving the use of the electromagnetic spectrum or directed energy to control the spectrum, attack an enemy, or impede enemy operations. The purpose of electromagnetic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. Electromagnetic warfare can be applied from air, sea, land, or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets.
The Northrop GrummanEA-6B Prowler is a twin-engine, four-seat, mid-wing electronic-warfare aircraft derived from the A-6 Intruder airframe. The EA-6A was the initial electronic warfare version of the A-6 used by the United States Marine Corps and United States Navy; it was used during the Vietnam War. Development on the more advanced EA-6B began in 1966. An EA-6B aircrew consisted of one pilot and three Electronic Countermeasures Officers, though it was not uncommon for only two ECMOs to be used on missions. It was capable of carrying and firing anti-radiation missiles (ARMs), such as the AGM-88 HARM.
The Grumman A-6 Intruder is an American twinjet all-weather attack aircraft developed and manufactured by American aircraft company Grumman Aerospace and formerly operated by the U.S. Navy and U.S. Marine Corps.
The Douglas A-3 Skywarrior is a jet-powered strategic bomber that was developed and produced by the Douglas Aircraft Company. It was designed by Douglas on behalf of the United States Navy, which sought a carrier-capable strategic bomber. In July 1949, Douglas was awarded the contract to produce its design, having bested eight other aircraft companies' submissions. Unlike rival designs, which had aimed for a 100,000 lb (45,000 kg) maximum take-off weight, the Skywarrior was developed for a 68,000 lb (31,000 kg) take-off weight, facilitating its use from the navy's existing Midway-class aircraft carriers. Large portions of the aircraft were produced by the Westinghouse Electric Corporation, including its early Westinghouse J40 turbojet engines, which failed to meet promises and were replaced by the rival Pratt & Whitney J57 engine by mid-1953. On 28 October 1952, the prototype XA3D-1 performed the type's maiden flight.
The Douglas F3D Skyknight is an American twin-engined, mid-wing jet fighter aircraft designed and manufactured by the Douglas Aircraft Company.
The Atlas Oryx is a medium-sized utility helicopter ostensibly developed and manufactured by the Atlas Aircraft Corporation of South Africa. Its largest operator is the South African Air Force (SAAF), having been originally developed to fulfil their needs.
The EC-130H Compass Call is an electronic attack aircraft flown by the United States Air Force. Based on the Lockheed C-130 Hercules, the aircraft is heavily modified to disrupt enemy command and control communications, perform offensive counterinformation operations, and carry out other kinds of electronic attacks. Planned upgrades will add the ability to attack early warning and acquisition radars. Based at Davis-Monthan AFB in Arizona, EC-130Hs can be deployed worldwide at short notice to support U.S. and allied tactical air, surface, and special operations forces.
Suppression of Enemy Air Defenses (SEAD, pronounced ), also known in the United States as "Wild Weasel" and (initially) "Iron Hand" operations, are military actions to suppress enemy surface-based air defenses, including not only surface-to-air missiles (SAMs) and anti-aircraft artillery (AAA) but also interrelated systems such as early-warning radar and command, control and communication (C3) functions, while also marking other targets to be destroyed by an air strike. Suppression can be accomplished both by physically destroying the systems or by disrupting and deceiving them through electronic warfare. In modern warfare, SEAD missions can constitute as much as 30% of all sorties launched in the first week of combat and continue at a reduced rate through the rest of a campaign. One quarter of American combat sorties in recent conflicts have been SEAD missions. Despite generally being associated with aircraft, SEAD missions may be performed using any means, including through actions by ground forces.
The Boeing EA-18G Growler is an American carrier-based electronic warfare aircraft, a specialized version of the two-seat Boeing F/A-18F Super Hornet. The EA-18G replaced the Northrop Grumman EA-6B Prowlers in service with the United States Navy. The Growler's electronic warfare capability is primarily provided by Northrop Grumman. The EA-18G began production in 2007 and entered operational service with the US Navy in late 2009. Australia has also purchased thirteen EA-18Gs, which entered service with the Royal Australian Air Force in 2017.
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers.
The Antonov An-12 is a four-engined turboprop transport aircraft designed in the Soviet Union. It is the military version of the Antonov An-10 and has many variants. For more than three decades the An-12 was the standard medium-range cargo and paratroop transport aircraft of the Soviet air forces. A total of 1,248 were eventually built.
The Shaanxi Y-8 or Yunshuji-8 aircraft is a medium size medium range transport aircraft produced by Shaanxi Aircraft Corporation in China, based on the Soviet Antonov An-12. It has become one of China's most popular military and civilian transport/cargo aircraft, with many variants produced and exported. Although the An-12 is no longer made in Ukraine, the Chinese Y-8 continues to be upgraded and produced. An estimated 169 Y-8 aircraft had been built by 2010.
A radar picket is a radar-equipped station, ship, submarine, aircraft, or vehicle used to increase the radar detection range around a nation or military force to protect it from surprise attack, typically air attack, or from criminal activities such as smuggling. By definition a radar picket must be some distance removed from the anticipated targets to be capable of providing early warning. Often several detached radar units would be placed in a ring to encircle a target to provide increased cover in all directions; another approach is to position units to form a barrier line.
The General Dynamics–Grumman EF-111A Raven is a retired electronic-warfare aircraft designed to replace the EB-66 Destroyer in the United States Air Force. Its crews and maintainers often called it the "Spark-Vark", a play on the F-111's "Aardvark" nickname.
Marine Tactical Electronic Warfare Squadron 2 (VMAQ-2) was a United States Marine Corps electronic warfare squadron in service from 1952 to 2019. It was the last squadron flying the Northrop Grumman EA-6B Prowler.

The Next Generation Jammer is a program to develop an airborne electronic warfare system, as a replacement for the AN/ALQ-99 found on the EA-18G military aircraft. It reached Initial Operating Capability in 2021.
The AN/APS-20 was an airborne early warning, anti-submarine, maritime surveillance and weather radar developed in the United States in the 1940s. Entering service in 1945, it served for nearly half a century, finally being retired in 1991. Initially developed at Massachusetts Institute of Technology (MIT) under Project Cadillac, the radar was developed to be carried by aircraft to extend the sensor range of ships by placing a radar at altitude. Although developed for carrier-borne operation, first being installed in the single-engined General Motors TBM-3W Avenger, it was also used in larger four-engined airframes, the last being a fleet of Avro Shackleton AEW.2 which were converted from maritime patrol aircraft. Similarly, although developed for detecting aircraft, it saw extensive service in anti-submarine and maritime patrol roles and was one of the first radars to be used in researching extreme weather like hurricanes by agencies like the Environmental Science Services Administration (ESSA). As well as the United States, the radar was used by a large number of services in other countries, including the French Navy, Japan Maritime Self-Defense Force (JMSDF), Royal Air Force (RAF) and Royal Canadian Air Force (RCAF). Early versions of the radar could see a low-flying aircraft at 65 nautical miles and a ship at 200 nautical miles. This was improved, so that later versions had a range against aerial targets of 115 nautical miles.
