Lancaster and Lincoln versus the Vickers Victory bomber

Did the Avro Lancaster and Avro Lincoln make the Vickers Victory bomber pointless?

No; they made the Vickers Victory less viable, although the aircraft could still have had some use.

Reduced competitiveness does not mean total uselessness. The arrival of the Avro Lancaster and Avro Lincoln would leave less reason to pursue the Vickers Victory as the preferred British bomber. The proposal could still retain some useful role after better alternatives appeared. This remains a cautious qualitative verdict, with no comparison of range, payload, performance, or production cost.
