Most modern attack aircraft carry their weapons externally - making supersonic flight near impossible until bombs have been released. In the case of the Buccanneer, which did have a bomb bay, it was arguable that the replacement Tornado was an inferior airframe, once one looked at mission range. The Tornado's avionics were far superior of course - but I was told the pilots flying the hack Buccaneers with early MRCA avionics thought that combination superb.The TSR2 would have had an internal bomb bay - so relationship with Iraq war experience does not apply, but that was designed more or strategic targets.
Something like the Jaguar, with updated avionics, might have done us very well in the present era, though.
