Hypersonic Boost-Glide Weapons
How do boost-glide weapons work? How effective will they be from a military standpoint?
Source: Science & Global Security
The United States, Russia and China are developing hypersonic boost-glide vehicles. A simple model of their trajectory is developed by assuming that the vehicle does not oscillate during the transition to equilibrium gliding. This model is used to analyze U.S. Department of Defense data on test flights for the Hypersonic Technology Vehicle-2. This glider's lift-to-drag ratio—a key performance parameter—is estimated to be 2.6. The model is also used to calculate the tactical warning time that a boost-glide attack would afford an adversary. Other aspects of boost-glide weapons’ military effectiveness are explored. Approximate calculations suggest that, compared to existing non-nuclear weapons, boost-glide weapons could penetrate more deeply but would be less effective at destroying silos. The distance at which a boost-glide weapon armed with a particle dispersion warhead could destroy a mobile missile is also calculated; it is expected to be significantly larger than for an explosive warhead....

- Europe Should Not Let Nuclear Nonproliferation DieCommentary
Amid uncertainty caused by the Iran war, the global drive for nonproliferation has stalled. With Europe diplomatically marginalized and countries reassessing their nuclear options, efforts to curb the spread of nuclear weapons risk becoming irrelevant.

- The EU Equivocating on Turkey Is Bad GeopoliticsCommentary
Following Ursula von der Leyen’s gaffe equating Turkey to Russia and China, relations with Ankara risk deteriorating even further. Without better, more consistent diplomatic messaging, how can the EU pretend to be a geopolitical power?
