“…It has a conical design and an estimated L/D of about 2.2-lower than that of the HTV-2, which had L/D of 2.6. 33 As a result, the DoD's decision to pursue a more mature technology will likely result in a BGV with less range and maneuverability than a successful wedge design with higher L/D would have. 34 This also means that the computational model we developed in Paper 1, based on the wedge design of the HTV-2, may somewhat over-estimate the flight performance of the C-HGB.…”

Hypersonic Missile Proliferation: An Emerging European Problem

The supposed benefits of hypersonic missile technology and the reconsideration of the European security landscape following Russia’s 2022 invasion of Ukraine may act as a catalyst for multiple European states to acquire or develop high-speed systems. Although these systems are currently challenging to develop, trends in other missile technology point towards a gradual diffusion of explicit and tacit knowledge that ultimately lowers production costs, resulting in greater affordability and accessibility. Coupled with inefficient non-proliferation barriers and the gradual erosion of the cold war arms control architecture, it is likely that these systems will be fielded by several European countries in the next 10 to 15 years. Reflecting this projection, this paper considers in detail various European hypersonic missile programmes and explains the applications of these systems and their possible implications for European stability, including existing technical and policy barriers that impede proliferation. In unravelling these, the paper proposes how policymakers can strengthen these mechanisms, achieve deterrence without undermining stability and better manage this emerging security issue.
