Avangard is a Russian hypersonic glide vehicle designed to deliver nuclear warheads. It can travel at speeds exceeding Mach 20, making it difficult for missile defense systems to intercept. The system is launched from a Borei-class submarine or a land-based platform, allowing for flexible deployment. The development of Avangard is part of Russia's efforts to modernize its military capabilities. It was officially introduced in 2019 and is intended to enhance strategic deterrence. The system's unique flight path and speed provide a significant advantage over traditional ballistic missiles.
