The whole V bomber series is interesting
Starting with the decision to take up three designs from manufacturers. And then another one.
Vickers Valiant (the most conventional) as the sure solution that would enter service soonest.
Handley Page Victor (unusual crescent wing) but more advanced than Valiant
Avro Vulcan (the most radical) but offering more performance promise
And then to make absolutely sure, the straight winged Short Sperrin - something closest to a WWII bomber with jet engines. Not handsome but useful as a test bed for jet engines (eg DH Gyron which was about 50% more powerful than an Olympus at one point). Shorts had proposed a design that was rejected as too radical so perhaps the Sperrin was a consolation prize.
Valiant - which dropped bombs for real (though during the Suez crisis) - suffered from spar fatigue when switched to low level attack, and withdrawn from service. That the B2 version (look for pictures of it at Farnborough 1953) designed for low level attack had been cancelled is a bit ironic.
Victor, a futuristic look with a bigger bomb bay and a near Mach 1 performance (also capable of loops and the odd barrel roll), also suffered when switched to low level. They were nearly used against Indonesia because of the bother over Malaya. They became tankers - the ones used to get the Vulcans to the Falklands.
