You missspelled it too, if it would be like you mean it would be: "Kyrgyzstan" and not "Kyrzgystan". But it doesn`t make a difference anyway, it is translated from the Cyrillic alphabet so it doesn`t really make a difference if you spell it with "y" or "i" or with "h" or without...
Kyrgyzstan actually exists but since Silo, like many other levels play in a fictive place I think it`s OK if we slightly change the name.
Just for the Record: Arkhangelsk, where the runway and the warfare facility is, is a city with a port in real life...
