I think RileyDove is rather missing the point when it comes to remembering the V-Force!
Obviously, if the V-Force had actually been used, it could have been regarded as being an heroic failure. The very fact that it never was used, ephasises that it was a huge success, and worth every penny.
The Vulcan's role in the Falklands and the Victor's role as a tanker (plus the recce role for which all three V-Bombers were used) were of course merely additional tasks which they performed admirably.
