Renowned Russian missile engineer Alexander Leonov, known for shaping some of Russia’s most advanced hypersonic weapons, has died at the age of 74. His passing marks the loss of a key figure behind major missile systems such as Zircon and the Indo-Russian BrahMos programme. Though official details about the place and cause of his death have not been released, Russian reports say he passed away in early April 2026. The man behind BrahMos and its future versions Leonov served as CEO and Chief Designer at NPO Mashinostroyeniya, Russia’s main partner in BrahMos Aerospacethe joint venture with India that develops the BrahMos missile family. During his leadership, he helped guide multiple versions of the missile, including the upcoming BrahMos-NG. This next-generation missile is designed to be lighter, harder to detect on radar, and suitable for smaller platforms while offering improved performance. His role ensured that BrahMos remained one of the world’s most respected supersonic cruise-missile systems. Key contributor to the Hypersonic Zircon missile Leonov is also closely linked to the development of the 3M22 Zircon hypersonic cruise missile. This advanced weapon can travel at speeds of up to Mach 9 about nine times the speed of sound. It can be launched from ships and submarines and is capable of hitting both sea and land targets at distances ranging roughly between 400 and 1,000 kilometres. Russian defence sources consider Zircon a major upgrade to naval strike power because it can evade many existing missile-defence systems. Wider impact on Russia’s missile and space programmes Under Leonov’s leadership, NPO Mash worked on several important defence systems, including the Granit and Bastion coastal-defence complexes. These systems use the Oniks missile, which later influenced the design of BrahMos. His team also contributed to parts of the Avangard hypersonic glide-vehicle system and radar-surveillance satellites, showing his influence beyond just cruise missiles. In 2019, he received Russia’s highest civilian honour, the “Hero of Labour,” for his contributions to missile and space technology. A lasting global defence legacy Defence experts believe Leonov’s work especially on Zircon and BrahMos-NG will continue shaping military planning in regions like the Indo-Pacific and Europe. His contributions highlight how individual engineers can influence the future of next-generation weapons worldwide.
