No, it is an Avro Vulcan as the title suggests. It is a British aircraft designed in the late 1940s to carry a nuclear weapon. The Rockwell B-1B is an American aircraft with variable geometry wings and not a big delta like the Vulcan.
Sorry for the delay in my reply, I've only just seen the question. There are a number of surviving V-Bombers in museums around the world. I think there are something like 20 Vulcans around the world in various museums, There are one or two Vulcans that remain in active condition, but mostly just for ground runs, but this example in my photographs is the last Vulcan that actually flies.
There are only five surviving Handley Page Victors left, all in the UK. Two of those five like some of the preserved Vulcans remain in active condition on the ground but none fly, well not on purpose anyway. (reference to an incident at Bruntingthorpe a few years back when a fast taxi became a short flight.)
Sadly for the third V-Bomber, the Vickers Valiant there are not as many survivors and I believe there is only one full intact example and that is at the Royal Air Force Museum at Cosford in Shropshire.
