The MiG-21 was designed as a clear-weather interceptor, and first flew in 1957 as the Ye-6 prototype. It entered service in 1958, however, in the following year it saw improvements in engine design as the 'Fishbed-C'. The 'Fishbed-D' followed two years later with an uprated engine and enlarged inlet to provide for a R1L Spin Scan-A radar.
The next generation Fishbeds featured improved engine and radar, internal cannon, additional fuel capacity, and two more external weapons pylons.
