DZ, the shape of an aircraft tends to be the result of its intended use. Buccaneer is a product of its age, as indeed Jaguar and Tornado were,
F35 needs weapons bays for stealth and stealth only, otherwise it becomes neccesary to design stealthy expendable stores. This is why there are similarities in aircraft types doing similar tasks. Remember it does take rather longer to design, test and introduce an aircraft into service than it does to build the Airfix kit of it.
As for your drivel regarding Tornado survivability in WW II and Jaguars designation capability, I guess you are on a slightly different planet than the rest of us.
