MiG-29UB / 9-51
In order to have the proper tool to tram pilots and field support crews for the MiG-29, the ОКБ developed the M1G-29UB two-seat variant concurrently. The и stands for uchebmy (training) and the h for boyevoy (combat)—meaning that this trainer retained at least limited combat capabilities. The radar was removed, but the cannon, IRST complex, laser range finder, and wing store stations of the single-seater remained At 17.42 m (57 feet, 18 inches) the M1G-29UB is 100 millimeters (3 94 inches) longer than the single-seater. This is the only structural difference necessitated by the second cockpit The one-piece canopy is hinged at the rear and opens upward There a periscope that provides the occupant of the rear cockpit with a wide field of vision. Both ejection seats are of the K-36DM type .
The MiG-29UB was first piloted on 29 April 1981 by A. G. Fastovets with a mannequin strapped to the second seat. The test schedule moved briskly, Mach 1 4 being reached on the fourth flight and Mach 1.9 on the ninth flight. Production got under way in 1982 for the WS and for export.
The MiG-29S has something of a fatback silhouette because its bigger electronics bay and slightly enlarged no. I fuel tank occupy the extended dorsal spine.
