Yak-26 Mandrake

Sure you don't mean the Yak-27? The Yak-26 was a bomber variant of the
Yak-25, and never entered service. The Yak-27, however, was a
high-altitude reconaissance variant.


Jay Miller calls it the 26 however he also believes it may be called
the Yak-25RD according to his book on the U-2, perhaps I need a newer
edition of this book.
