As early as 1979, Soviet aircraft designers started work on a programme called I-90, a fighter for the 1990s. Two Soviet aircraft design bureaux took on the task, Mikoyan and Sukhoi. Work began in 1983 but with the dissolution of the Soviet Union the project stalled.
The book charts the development and trials history of the 1.44, Su-47 and Su-57, as well as other project versions that did not make it to the hardware stage. It is illustrated with about 500 previously unpublished colour photos (also details), technical drawings, 14 pages with b/w drawings as well as about 70 colour profiles illustrated.
