I think Taranis is of interest to some people (and that is more uniquely British than Concorde). I do agree though, that without having any context to these models, they are just that. I mean BAE had some real cutting edge designs in the 90s, and now it makes the ar$e of the F35 for a living.
BAe’s real money comes from asset-stripping small companies it buys up. And buying small US firms to sell to the US government.
