Taranis
Taranis is, no matter what BAES may claim, an effort to support Defence Industrial Infrastructure - not to develop military capability.
At inception, MoD submitted their requirements for a UCAS to industry along with the available budget. After the laughter subsided, only BAES were left standing, with a proposal to 'explore' what might be achieved in the areas of stealth and UCAS engine technology - very little else.
Compare it to the European (read French) Neuron programme or the US X45 and Taranis is revealed as a bit of a joke.
The contract was let largely on its ability to function as a piece of work to maintain/develop 'cutting edge' UK capability in this area whilst awaiting a real, funded UCAS programme.
I've worked on the edges of this programme and I am not a fan.
