 | | To meet this challenge, Vickers, Avro, and Handley Page were each called upon to develop bombers for the Royal Air Force culminating in the Valiant, Vulcan, and Victor. |
 | | Avro opted for a delta wing design in its model 698, the Vulcan, second of the triad to enter service. |
 | | As the B.1 began entering service as a high-level bomber, Avro began development of an improved B.2 with an enlarged wing, revised control surface arrangement, in-flight refueling capability, and lengthened fuselage. |
