Russia’s Avangard hypersonic missile, capable of reaching speeds up to Mach 27, was scheduled for a fresh test in early September 2026 but the launch was unexpectedly cancelled. Preparations at the Dombarovskiy airbase were confirmed, yet no official reason has been given for the delay.

Russia has been preparing to launch the Avangard hypersonic cruise missile from its Dombarovskiy airbase in the Orenburg region.

Kremlin-backed state media highlighted that preparations were underway, with the test initially scheduled for the first week of September. However, the launch was moved ahead and eventually cancelled without explanation.

The Avangard remains the fastest missile in the world, capable of reaching speeds up to Mach 27. Russia first tested this missile in 2018, with President Vladimir Putin personally witnessing the launch. Earlier this year, Putin confirmed that the Avangard system had been fully deployed, though it continues to undergo upgrades to enhance its operational effectiveness.

The planned test was expected to involve a MIRV capable UR-100N UTTKh intercontinental ballistic missile carrying the Avangard hypersonic glide vehicle, launched from Dombarovskiy towards the Kura missile test range in Kamchatka.

Aviation warnings and Notices to Air Missions (NOTAMs) were issued, temporarily closing sections of airspace and alerting residents in Tyumen and Khanty-Mansi regions about possible rocket-stage impact zones.

Expert analysis indicates that the restricted zones matched those used in earlier Avangard tests in 2013, 2015, 2016, and 2018, confirming that the system rather than the RS-28 Sarmat missile was being prepared. The cancellation has sparked speculation, though there were no signs of a launch accident.

The Avangard is a strategic missile system equipped with a hypersonic glide vehicle capable of carrying a nuclear warhead. Unlike conventional ballistic warheads, the glide vehicle travels through the atmosphere at hypersonic speed and can manoeuvre laterally and vertically, making its trajectory unpredictable and extremely difficult for missile defence systems to intercept.

Putin has consistently presented the Avangard as a response to U.S. missile defence developments, claiming it can penetrate next-generation shields. The system entered service in 2019, and its deployment has been seen as a major leap in Russia’s strategic deterrence capability.

Russia also intends to integrate the Avangard with the RS-28 Sarmat intercontinental ballistic missile, which would provide the glide vehicle with greater range, speed, and lethality. This combination is expected to significantly expand Russia’s strike options, reinforcing its nuclear deterrence posture.

The cancellation of the September test raises questions about technical readiness, strategic timing, or political considerations. Analysts suggest that despite the delay, Russia will likely reschedule the test soon, given the symbolic and strategic importance of the Avangard program.
