Editing Avro Vulcan (section)

==Variants==
;B.1
:The initial production aircraft. The first few had straight leading edges, later retrofitted with phase 2 (kinked) wings. Early examples were finished in silver, later changed to "[[Anti-flash white|anti-flash" white]]. Many were converted to B.1A standard 1959–1963. The last few unmodified B.1s in RAF service with No. 230 OCU retired by 1966.<ref>Darling 2007, p. 60.</ref> Last flight by any B.1, an engine testbed XA903, March 1979.<ref>Laming 2002, p. 99.</ref>

;B.1A
:The B.1 with an ECM system in a new larger tail cone (as in B.2).<ref name ='brookes16-17'>Brookes and Davey 2009, pp. 16–17.</ref> Unlike the B.2, the B.1As did not undergo extensive wing strengthening for low-level flying<ref name ='brookes14'/><ref>Brookes and Davey 2009, pp. 14, 92.</ref> and were withdrawn from service 1966–67.<ref>Darling 2007, pp. 62–63.</ref>

;B.2
:Developed version of the B.1. Larger, thinner wing than the B.1 (Phase 2C wing) and fitted with Olympus 201-202 engines, or Olympus 301 engines. Uprated electrics with AAPP and [[Ram Air Turbine]] (RAT).<ref name = 'brookes10'>Brookes and Davey 2009, p. 10.</ref> ECM similar to B.1A. TFR in nose thimble radome fitted to most aircraft in the mid-60s. New [[Radar warning receiver]] aerials on tail fin giving it a square top from the mid-1970s.{{refn|Some sources have attested to the existence of a Vulcan ''B.2A''. This designation supposedly referred either to Vulcan B.2s fitted with Olympus Mk 301 engines or those modified to carry the Blue Steel missile.<ref name ='brookes92-93'>Brookes and Davey 2009, pp. 92–93.</ref><ref name = 'polmar262'>Polmar and Bell 2004, p. 262.</ref> However, irrespective of the role or engine fit, the B.2 was the only official designation except for the MRR and tanker variants.<ref name="laming64"/><ref>Bulman 2001, p. 154.</ref>|group=N}}

;B.2 (MRR)
:Nine B.2s converted to maritime radar reconnaissance (MRR). TFR deleted. Five aircraft were further modified for the air sampling role. Distinctive gloss finish with light grey underside.<ref name="Brookes83"/>

;K.2
:Six B.2s converted for air-to-air refuelling with Mark 17 hose drum unit (HDU) mounted semi-recessed in the tail cone. TFR deleted. Fitted with three bomb-bay drum tanks, it was the only mark of Vulcan that could jettison fuel in an emergency.<ref>Darling 2007, pp. 122–124.</ref>

;B.3
:Proposed version, intended as a long-endurance missile carrier capable of carrying up to six Skybolt missiles on flights of up to 12 hours duration. Never built.<ref name="Gibson" />

===Production===
A total of 134 production Vulcans were assembled at Woodford Aerodrome, 45 to the B.1 design and 89 were B.2 models, the last being delivered to the RAF in January 1965.<ref name = 'brookes10'/>
