Early configurations of the Tu-144 were based on the unbuilt Tupolev Tu-135 bomber, retaining the latter aircraft's canard layout, wings and nacelles. Deriving from the Tu-135 bomber, Tupolev's early design for supersonic passenger airplane was code-named Tu-135P before acquiring the Tu-144 project code.
