Anyway, very interesting machine and the program said that the replica showed a 20% reduction in the radar cross section compared to other aircraft. With its speed, reduced RCS, it would have been very difficult to intercept if not impossible.
Sorry that is wrong. Not 20% RCS reduction but 20% range reduction. For a range reduction of 20% need you a RCS reduction of 60% for the Chain Home.
Advance warning time for the Chain Home low only 2.5 minutes.
