Service Life

Vulcans and Victors (as tanker aircraft) were used in the 1982 Operation Black Buck missions so I am wondering why this article refers to the aircraft being in service 1958 and 1956 respectively. Three Vulcans XM597, 598 and 607 are identified in the Operation Black Buck article as being involved in operational bombing missions. The article on the Handley Page Victor states that it was retired nine years after the last Vulcan. Unfortunately, the Vulcan article does not give a last operational use date, although note should be taken that, according to the article, the last production Vulcans were delivered to the RAF in January 1965. Can someone clarify the dates and modify the dates in the relevant articles please? Vulcans and Victors must have been operational in 1982. If the Vulcans were retired immediately after the Falklands War (1982), Victors must have been operational until 1991. It seems to me that there are so many inconsistencies that clarification is essential to meet the Military History project objectives.
