Repellent-1 (Russian: Репеллент-1) is a Russian electronic warfare system [1] designed to suppress the operation of unmanned aerial vehicles [2] at a distance of up to 30 to 35 km (19 to 22 mi).
In September 2003, an announcement was made that Lockheed Martin's "Skunk Works" was developing a stealthy air-launched UCAV named "Minion".Its radar cross section is smaller than that of the F/A-22 Raptor (return smaller than a marble) and F-35 Joint Strike Fighter [1] Details released describe it as having a launch weight of 3,400 kilograms (7,500 pounds) and able to carry a reconnaissance ...
The EDM4S or EDM4S SkyWiper (Electronic Drone Mitigation 4 - System), is a portable electronic warfare anti-drone device produced and developed by the Lithuanian company NT Service [1] It is designed to disrupt small and medium sized UAVs by jamming their communication and satellite navigation systems with an electromagnetic pulse.
A US Navy EA-18G Growler, loaded with AGM-88 HARM anti-radiation missiles. Suppression of Enemy Air Defenses (SEAD, pronounced / ˈ s iː-æ d /), 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 ...
The Z-10's engine system is fitted with the Hover Infrared Suppression System (HIRSS), mixing in the engine exhaust with cold air to reduce the helicopter's infrared characteristic. [14] Later serial production of Z-10 modified the engine nozzle from sideway-facing to the upward-facing direction, further reducing the signature from heat ...
The first S-70 prototype has a non-stealthy circular exhaust. The Okhotnik's design is based on the flying-wing scheme and incorporates use of composite materials and stealth coatings, reducing the drone's radar cross section in flight. [26] It has a weight of about 20 tons and a wingspan of around 65 feet (20 m).
Apart from military use, some civilian aircraft are also equipped with countermeasure flares, against terrorism: the Israeli airline El Al, having been the target of the failed 2002 airliner attack, in which shoulder-launched surface-to-air missiles were fired at an airliner while taking off, began equipping its fleet with radar-based, automated flare release countermeasures from June 2004.
The fuselage, tailfin, radio control system, and parachute recovery system of the MQM-74A were retained, but the drone was fitted with a new wing, a Teledyne CAE J402 engine with a rotating vectored thrust exhaust, fixed tricycle landing gear, and additional flight control systems. The demonstrator was completed and was making tethered flights ...
