B-58 'Hustler' for me. 'The Doomsday Jet', the huge pod underneath containing the nuke indicative of its sole purpose. The aircraft was not designed to deliver conventional weapons.
Footage of Hustlers was used to represent the 'Vindicator' bombers in the apocalyptic movie 'Fail Safe'.
Trivia alert: the singer John Denver's father commanded a Hustler squadron, mentioned in a description of a typical training mission: look under war stories > typical mission at

Reading the article, I found the takeoff and landing speeds eye-watering, and the mission lengths and working environment challenging, to say the least.
Edited to add that John's dad must have been better at fuel management than his son.
