Including the three prototypes, a total of 107 Valiants were built.
Valiant B.1: 37 pure bomber variants, including five pre-production Type 600, Type 667 and Type 674s, which were powered by Avon RA.14 engines with the same 9,500 pounds-force (42 kN) thrust each as the earlier Avon 201 and 34 Type 706 full-production aircraft, powered by Avon RA.28, 204 or 205 engines with 10,500 pounds-force (47 kN) thrust each, longer tailpipes and water-methanol injection for takeoff boost power.
Type 710 Valiant B(PR).1: eleven bomber/photo-reconnaissance aircraft.
Edwards and his team had considered use of the Valiant for photo-reconnaissance from the start, and this particular type of aircraft could accommodate a removable “crate” in the bomb-bay, carrying up to eight narrow-view/high resolution cameras and four survey cameras.
Type 733 Valiant B(PR)K.1: 14 bomber/photo-reconnaissance/tanker aircraft.
Type 758 Valiant B(K).1: 44 bomber / tanker aircraft.
Both tanker variants carried a removable tanker system in the bomb bay, featuring fuel tanks and a hose-and-drogue aerial refuelling system.
A further 16 Valiant B(K).1s were ordered, but cancelled.
Valiant B.2: 1 prototype.
Vickers also considered an air transport version of the Valiant, with a low-mounted wing, wingspan increased from 114 feet 4 inches (34.85 m) to 140 feet (43 m), fuselage lengthened to 146 feet (45 m), and up-rated engines.
Work on a prototype, designated the Type 1000, began in early 1953.
The prototype was to lead to a military transport version, the Type 1002, and a civilian transport version, the Type 1004 or VC.7.
The Type 1000 prototype was almost complete when it, too, was cancelled.
