I see that the first lecture of the Cambridge RAeS 14/15 lecture season is the people from HAV at Cardington. Having read all the comments on here I don't think I shall bother going. - perhaps I should so I can make my own mind up.
Sorry I did not get Oberons point about RCS. I did not see stealth as a KUR.
Perhaps t45321 has a point about the technical advances in materials, powerplants, and aerodynamics making this project more viable. I saw an interesting MDBA promo showing the airship being used as a launch vehicle for guided weapons.
