Hypersonic Systems The Challenge

The emergence of hypersonic systems defines the new boundary of kinetic warfare, characterized by extreme speeds and unpredictable flight trajectories. Hypersonic vehicles, capable of sustaining Mach 5 or greater, represent a disruptive departure from the predictable arcs of traditional ballistic missiles. By operating within the upper layers of the atmosphere and maintaining the ability to maneuver, these systems challenge the very foundations of current integrated air and missile defense (IAMD). The strategic logic of hypersonics lies in their ability to compress the decision-making window of an opponent, potentially bypassing legacy detection and interception frameworks.

This article analyzes the technical requirements and the strategic implications of this shift toward high-speed contention in the European theater. Deterrence by denial now depends on the ability to track and neutralize these threats throughout their entire flight envelope, from launch to terminal phase. The transition toward hypersonic resilience is a primary objective of the NATO 2022 Strategic Concept and the EU Strategic Compass. This introductory paragraph frames the hypersonic challenge as a race for superior maneuverability and sensing in a domain that was previously considered a sanctuary.

Achieving a credible defense against these systems is a prerequisite for maintaining the stability of the international order. The following analysis explores the technological hurdles and the collaborative efforts required to master this high-speed domain. Hypersonic threats are primarily categorized into two families: Hypersonic Glide Vehicles (HGVs) and Hypersonic Cruise Missiles (HCMs). HGVs are launched by conventional boosters but spend most of their flight gliding at high altitudes, using aerodynamic lift to perform evasive maneuvers that defeat radar prediction.

HCMs, on the other hand, utilize air-breathing scramjet engines to maintain high-speed flight across lower altitudes, complicating the detection process due to the curvature of the Earth.
