Hypersonic Defense
Hypersonic defense is the system and strategy used to protect against missiles traveling at hypersonic speeds, which is more than five times the speed of sound. These systems must detect, track, and intercept extremely fast and maneuverable threats.

TECHNICAL DEFINITION
Hypersonic defense encompasses the layered architecture of sensor networks, command and control (C2) systems, and advanced interceptors designed to counter hypersonic threats like Hypersonic Glide Vehicles (HGVs) and Hypersonic Cruise Missiles (HCMs). This defense strategy involves a complex kill chain, from space-based satellite tracking in the 'birth-to-death' phase to terminal phase interceptors like the Glide Phase Interceptor (GPI), addressing challenges of extreme velocity, maneuverability, and plasma stealth.
BACKGROUND
The Golden Dome is a planned multi-layer missile defense system for the United States, intended to detect and destroy ballistic, hypersonic, and cruise missiles before they launch or during their flight.

USAGE NOTE
Developing a credible hypersonic defense capability is a top priority for the Pentagon due to the significant challenge these weapons pose to existing air and missile defense systems.
DEVELOPERS
Organizations developing technology related to Hypersonic Defense.
A prime contractor for the U.S. Missile Defense Agency's Glide Phase Interceptor (GPI) program, designed to intercept and defeat hypersonic glide vehicles during their glide phase of flight.
A major defense contractor developing a portfolio of hypersonic technologies, including interceptors and advanced sensor systems. The company is actively involved in multiple U.S. government programs to counter hypersonic threats.
