Hobby Master 1/72 Air Power Series (Jet Powered) HA0125 - Soviet Mig-21SMT Soviet Air Force Frontal Aviation Units |
Background history of the Mig-21SMT
The Mig-21SMT ( NATO designation Fishbed K ) was a third generation version and
only flown by the pilots of the Soviet Air Force Frontal Aviation Units and they were used
primarily in an air-ground role. Along with a new ECM package the designers made an
effort to increase the endurance of the Mig-21 by enlarging the dorsal fin and lengthened
it so it went back and merged with the brake chute fairing. This gave it a humpbacked
look and made it possible to carry 3,250 liters internally but this lead to fuel trim
problems, when 2/3 of the fuel was burned off the center of gravity would shift towards
the tail, severely hampering performance and handling. To make things worse the R-13-
300 engine was used which didn’t produce enough thrust to compensate for the
increased weight of the SMT over previous models. The SMT version turned out to be
quite a disappointment with only about 150 – 200 machines ever being built from 1971 –
1972 and 15of the export version, the MT were produced but none were ever exported.
However lessons were learned from this and since the full amount of fuel couldn’t be
carried the next version arrived with a smaller spine that didn’t go back to the brake
chute fairing.
