The German Air Force took part in the NATO joint opertion with an Electronic Warfare Squadron Marine Attack Squadron 4 (VMA-Q4) EA6-B Prowler aircraft from Marine Corps Air Station Cherry Point, North Carolina. Location: COLD LAKE, ALBERTA (AB) CANADA (CAN)
context_page_description: The Mikoyan MiG-29 is a twin-engine jet fighter aircraft designed in the Soviet Union. Developed by the Mikoyan design bureau as an air superiority fighter during the 1970s, the MiG-29, along with the larger Sukhoi Su-27, was developed to counter new U.S. fighters such as the McDonnell Douglas F-15 Eagle and the General Dynamics F-16 Fighting Falcon. The MiG-29 entered service with the Soviet Air Forces in 1982.
  While originally oriented towards combat against any enemy aircraft, many MiG-29s have been furnished as multirole fighters capable of performing a number of different operations, and are commonly outfitted to use a range of air-to-surface armaments and precision munitions. The MiG-29 has been manufactured in several major variants, including the multirole Mikoyan MiG-29M and the navalised Mikoyan MiG-29K; the most advanced member of the family to date is the Mikoyan MiG-35. Later models frequently feature improved engines, glass cockpits with HOTAS-compatible flight controls, modern radar and infrared search and track sensors, and considerably increased fuel capacity; some aircraft have also been equipped for aerial refueling.
context_section_description: The baseline MiG-29B has a Phazotron RLPK-29 radar fire control system which includes the N019 Sapfir 29 look-down/shoot-down coherent pulse-Doppler radar and the Ts100.02-02 digital computer.
  The N019 radar was not a new design, but rather a development of the Sapfir-23ML architecture used on the MiG-23ML. During the initial design specification period in the mid-1970s, Phazotron NIIR was tasked with producing a modern radar for the MiG-29. To speed development, Phazotron based its new design on work undertaken by NPO Istok on the experimental "Soyuz" radar program. Accordingly, the N019 was originally intended to have a flat planar array antenna and full digital signal processing, for a detection and tracking range of at least 100 km against a fighter-sized target. Prototype testing revealed this could not be attained in the required timeframe and still fit within the MiG-29's nose. Rather than design a new radar, Phazotron reverted to a version of the Sapfir-23ML's twisted-polarization cassegrain antenna and traditional analog signal processors, coupled with a new NII Argon-designed Ts100 digital computer to save time and cost. This produced a working radar system, but inherited the weak points of the earlier design, plaguing the MiG-29's ability to detect and track airborne targets at ranges available with the R-27 and R-77 missiles.
  The N019 was further compromised by Phazotron designer Adolf Tolkachev’s betrayal of the radar to the CIA, for which he was executed in 1986. In response to all of these problems, the Soviets hastily developed a modified N019M Topaz radar for the upgraded MiG-29S aircraft. However, VVS was reportedly still not satisfied with the performance of the system and demanded another upgrade. The latest upgraded aircraft offered the N010 Zhuk-M, which has a planar array antenna rather than a dish, improving range, and a much superior processing ability, with multiple-target engagement capability and compatibility with the Vympel R-77 (or RVV-AE).
