The development of an AESA radar first came up in our country back in the 1980s, when, in accordance with the Targeted Integrated Program for the Development of Fighter Aircraft in the 1990s, approved in 1983, the Mikoyan Design Bureau began designing an advanced fifth-generation fighter—the MFI Multifunctional Fighter (Project 1.42).
The lead developer of the aircraft's weapons control radar system was designated the Radio Engineering Research Institute (NIIR), which later became the foundation for today's Fazotron-NIIR Corporation. Work on the MFI was conducted in response to information received about the development of the ATF (now known as the F-22) in the United States, which was initially planned to be equipped with an AESA radar. Therefore, the possibility of developing an AESA radar system for the MFI was also considered. This idea was supported by the lead developer of the N014 radar system for the Moscow Institute of Physics (MFI), NIIR. However, the lack of experience and the necessary technological base for developing an APAA in the Soviet Union at that time forced the idea to be abandoned. The N014 was designed with three passive phased arrays (a central one and two side ones), which provided forward airspace coverage in the forward hemisphere over an azimuth range of ±130°. While NIIR retained its leadership role in developing the entire N014 radar, the development of antenna systems with passive phased arrays for it was entrusted to the V.V. Tikhomirov Research Institute of Instrument Engineering (NIIP), which had already developed and commissioned the country's first "aircraft" phased array radar, the "Zaslon" (Barrier) for MiG-31 interceptors. While participating in the N014 radar project, NIIP began work on a promising AESA radar for a unique long-range, high-speed interceptor designed at the Mikoyan Design Bureau in the late 1980s. Unfortunately, neither project was completed, hampered by the collapse of the Soviet Union and the corresponding change in policy in the field of weapons development and procurement.
