During the initial MiG-29 design specification period in the mid-1970s, Phazotron NIIR was tasked with producing a modern radar for the MiG-29. Instead, the system was a further development of the architecture already used in Phazotron's Sapfir-23ML system, then in use on the MiG-23ML. These performance deficiencies stemmed largely from the fact the N019 radar was not, in fact, a new design.

Early Western speculations suggested that the Ram-L was very similar in appearance to the YF-17 and powered by afterburning Tumansky R-25 turbojets.Īll -swept low-wing configuration, with wide ogival wing leading-edge root extensions (LERX), lift-generating fuselage, twin tail fins carried on booms outboard of widely spaced engines with wedge intakes doors in intakes, actuated by extension and compression of nosewheel leg, prevent ingestion of foreign objects during take-off and landing gap between roof of each intake and skin of wingroot extension for boundary layer bleed fire control and mission computers link radar with laser rangefinder and infrared search/track sensor, in conjunction with helmet-mounted target designator radar able to track 10 targets simultaneously targets can be approached and engaged without emission of detectable radar or radio signals sustained turn rate much improved over earlier Soviet fighters thrust/weight ratio better than one allowable angles of attack at least 70 per cent higher than previous fighters difficult to get into stable flat spin, reluctant to enter normal spin, recovers as soon as controls released wing leading-edge sweepback 73 degrees 30′ on LERX, 42 degrees on outer panels anhedral approx 2 degrees tail fins canted outward 6 degrees leading-edge sweep 47 degrees 50′ on fins, approx 50 degrees on horizontal surfaces. The pre-production aircraft was first spotted by United States reconnaissance satellites in November of that year it was dubbed Ram-L because it was observed at the Zhukovsky flight test center near the town of Ramenskoye. Detailed design work on the resultant Mikoyan Product 9, designatedMiG-29A, began in 1974, with the first flight taking place on 6 October 1977. The PFI fighter was assigned to Sukhoi, resulting in the Sukhoi Su-27, while the lightweight fighter went to Mikoyan. PFI and LPFI paralleled the USAF's decision that created the "Lightweight Fighter" program and the General Dynamics F-16 Fighting Falcon and Northrop YF-17.
The PFI program was supplemented with the LPFI(Perspektivnyy Lyogkiy Frontovoy Istrebitel, or "Advanced Lightweight Tactical Fighter") program the Soviet fighter force was planned to be approximately 33% PFI and 67% LPFI. However, in 1971 Soviet studies determined the need for different types of fighters.
