Definitely a beautiful aircraft but.....
the Vigilante had a severe problem with releasing weapons from its 'interesting' weapons bay located lengthwise between the engines. Bombs were to be ejected aft out of the bay, attached to disposable fuel tanks. During trials, stores jammed half in and half out, stuck between the jet pipes, or the tanks burst (leading to one aircraft being lost). These problems were so insoluble that the attack variant never entered service, and the aircraft were converted to the RA-5 variant.
There were also problems with the avionics fit as well as the complex airframe and systems. It was, by all accounts, an extremely challenging aircraft to land back on to carriers.
Best Regards as ever to all
