I always thought the Vulcan's stand-off weapon kicked ass. Designed for use on the trio of V-bombers, the Blue Steel (1.1 Megatons..

) seemed most at home hanging under the Vulcan. Inevitably, the missile, and the V-bombers themselves were rendered largely obsolete by Polaris and subsequent SLBM's. The Victor and Valiant were retired after relatively short service lives, leaving the Vulcan, relegated to conventional bombing and tanker duties, to soldier on. I saw the plane and the missile once @ RAF Duxford. Very Cool!


Flash protection from its nuclear payload.
Yep, same reason the planes were initially painted white overall. Same reason why B-47's and early B-52's were white on the bottom.
It always seemed odd to me that, although the Vulcan was a contemporary of the B-47, the B-52, and, to some extent, the B-58, that it had no tail gun. Especially given the lousy rear visibility.
