I feel I have provided additional, relevant information throughout the duration of this question, increasing the ease of which it may be correctly answered with. I also feel that I have responded to answers in a pretty prompt manner - it's not like I have asked the question, gone away & let it die.
Several answers have not considered some of the fact's provided, such as that it is subsonic, that is flew before the Harrier & other VTOLs, that is is not VTOL, that it come from a family of versatile A/C - some of which still serve, that is a carrier based A/C, or that the vectoring was proposed to ease carried handling.
I argue the fact that this is an obscure question, or that I have failed to provide enough information - come on, how many subsonic carrier A/C which flew in the early sixties are still in, or have very recently been in service.
