Yakovlev Yak-33

The Yakovlev Yak-33 was a vertical takeoff and landing supersonic multi-purpose aircraft family, studied in the early 1960s, with variants of a basic design used to fulfill different roles, in a similar fashion to the Yak-25, Yak-27, Yak-28 family.[1]

Yak-33
Role VTOL fighter/bomber/reconnaissance aircraft
Manufacturer Yakovlev
Status Project only

Several configurations were studied including canard and tailless deltas, however matching supersonic performance with VTOL ability seriously compromised the design's ability to carry out its primary missions.[1]
