That would depend on your definition of "strategic".For instance it falls somewhere between its faster us cousin the b58 hustler and its slightly older and slower british counterpart the avro vulcan in terms of speed,its payload is around the same,but its combat range is inferior at around 2500km.The blinders range is around 30% less than its predecessor the tu16,but it is supersonic so you would expect that as that tended to be the trade off with the more powerful,but more thirsty,turbojets of the era.Ultimately its certainly not in the same class as the heavyweight strategic machines of the cold war era,like the sub sonic b52 or tu95 or the supersonic b1b or tu160,that we tend to think of when hearing the term "strategic bombers",but its performance still puts it towards the bottom end of the medium supersonic bomber class of its day.
