The BESA Center’s recent detailed study on Unexplained Aerial Phenomena (UAP) described the post-quantum revolution in military affairs unfolding as a result of studying UAP “observables” and assessed the strategic implications in terms of potential threats emanating from UAP or adversaries. This paper delves further into “beyond next generation” technologies. It is based on recent comments by Luis Elizondo, former director of the Pentagon´s Advanced Aerospace Threat Identification Program, as well as analyses by scientists and former DoD insiders. The questions to be addressed are: What are the capabilities of these technologies, what decisive advantages would they provide, and how likely are they to be developed and deployed?
