Look for info: Yak-45 and Yak-47 !!

Does anyone have some more information regarding these two fighter projects from Yakovlev … all I found so far are two sketchy plans of them, some data … and a model-picture of a VSTOL-derivate of the Yak-45 !

As I remember was the Yak-45 proposed in the class of the MiG-23 and the Yak-47 in the class of the Su-27 and both lost out these contests against the MiG-29 and Su-27 !!

I think I also have seen in an German book – don’t know the title – a drawing of a later (?) design with a delta-canard layout and the typical Yakovlev podded engines !

Thanks in advance, Deino 🙂
