The Vigilante’s design with the broad body, wing on top and side air intakes with the top over hang was indeed the grandfather of the later fighters. Altho it had just the one vertical tail member, look it up, NA’a first design had two, but the Navy reject it. With the original design the Vigilante looked exactly like a larger F-15.
I supose that the Fairey Delta was the prototype for the Eurofighter Typhoon, and the Dassault Rafale then… Or was it the Mikoyan ye-8? It looks just like a Gripen, just like a Vigilante looks like a Tomcat.
Look, North American Rockwell did answer to the FX (the one that MD won and gave the USAF the Eagle) competition with this:

And the only thing in common with the Vigilante its the name of the company and the fact that its a twin engined jet, nevermind all the other jets that you´ve mentioned, Grumman didnt build the tomcat based on the Vigilante, neither did MDouglas for the Eagle and the idea that the Fulcrum was based on North American Rockwell work is… Words elude me.
