The Mikoyan MiG SVB (in Cyrillic: Микоян МиГ СВБ) was a Russian initiative during the 1990s aimed at creating a turboprop regional passenger and freight aircraft designed to operate effectively in hot and high conditions, including capabilities for night and all-weather flights. This model was projected to offer substantially reduced operational expenses compared to contemporaneous aircraft like the Antonov An-32, primarily due to its use of modern, lower-powered Klimov TV7-117S engines.

The acronym "SVB" derives from the Russian phrase Samolet Vysotnogo Bazirovaniya (Самолет Высотного Базирования), which translates as "Aircraft for high-altitude bases," and internally at MiG it was designated as article 801 (изделие 801, izdeliye 801). The project was ultimately discontinued in 1994 due to the political and economic turmoil associated with the dissolution of the Soviet Union.

Design

The SVB featured a conventional layout typical of its category: it was designed as a shoulder-wing cantilever monoplane with a traditional tail assembly. The landing gear was planned as retractable tricycle type, with the main wheels retracting into fairings along the fuselage sides, supplemented by flotation equipment. Two turboprop engines were to be wing-mounted, each driving tractor propellers. The wings incorporated high-lift devices to enhance performance. A distinctive aspect of the design was its fuselage, which retained a uniform rectangular cross-section extending from behind the cockpit to the tail.

For passenger transport, two main seating arrangements were proposed: a standard layout accommodating 40 passengers in eight rows of five seats, and a denser configuration seating 50 passengers across ten rows with reduced seat pitch. Both versions featured a single aisle positioned towards the starboard side.

In its cargo role, the SVB would have included a rear fuselage loading ramp, along with an electrically powered hoist mounted on ceiling rails inside the cabin. The entire interior space was designed to be fully pressurized.

Development

The SVB emerged as one of MiG's konversiya ("conversion") initiatives. During the late 1980s, as tensions of the Cold War diminished, Soviet defense producers were required to shift part of their manufacturing efforts towards civilian applications. This project was initiated by Fatidin R. Mukhamedov, who led MiG's Dushanbe branch and had direct insight into the difficulties associated with air transport in Tajikistan. There, runways were often short, situated at elevations reaching 4,000 metres (13,000 ft), and temperatures could climb to 40 °C (100 °F). The objective was to create an aircraft capable of transporting 5 tonnes (11,000 lb) of freight across distances up to 1,500 kilometres (930 mi; 810 nmi), operating effectively under these environmental constraints. Design efforts spanned from 1990 until 1994.
