Russia’s ambition to field a formidable new intercontinental ballistic missile, the RS-28 Sarmat, is facing significant headwinds. Touted as a cornerstone of its nuclear deterrence strategy, this ‘doomsday weapon’ has been plagued by a series of high-profile failures, casting a shadow over its intended role and raising questions about Russia’s military modernization efforts.
The Promise of the Sarmat: A New Era of Deterrence?
Vladimir Putin has frequently championed the Sarmat, often referring to it as a "truly unique weapon" designed to provide "food for thought" for any nation that might threaten Russia. With the capability to deliver payloads of up to 10 large nuclear warheads, or a combination of warheads and advanced countermeasures like hypersonic glide vehicles, the Sarmat is envisioned as Russia’s ultimate strategic deterrent. Its projected range of over 11,000 miles (18,000 kilometers) makes it the longest-range missile in the world, capable of reaching virtually any target on the globe.
This next-generation heavy-duty ICBM is intended to replace Russia’s aging R-36M2 strategic missile fleet, a legacy system built during the Soviet era. The Sarmat, often dubbed "Satan II" in the West, represents a significant leap in Russian indigenous missile technology, with its development relying solely on domestic industrial cooperation, a point emphasized by Russia’s Ministry of Defense.
A Troubled Trajectory: From Hype to Hard Landings
The narrative surrounding the Sarmat, however, has been far from smooth. While its first full-scale test flight in 2022 was reportedly successful, subsequent efforts have been marred by a string of critical failures. The most recent incident, occurring on a Friday in early December 2025, saw a missile launched from an underground silo near the Russian-Kazakh border fail catastrophically. Instead of reaching its intended impact zone nearly 4,000 miles away, the missile veered off course almost immediately after launch, spiraled uncontrollably, and crashed a mere 4,000 feet from the launch site.
The dramatic event was captured on video, widely shared across social media platforms, and vividly depicted the missile cartwheeling upside down before impacting the ground. The crash was accompanied by a fiery explosion and a distinctive reddish-brown cloud, a telltale sign of the highly toxic propellants – hydrazine and nitrogen tetroxide – used in Russia’s most powerful ICBMs. Satellite imagery later confirmed a visible crater and burn scar at the crash site, a stark testament to the failed launch.
The Mystery Missile: Sarmat or Something Older?
While the Russian military has remained conspicuously silent about the recent accident, analysts are confident that the missile in question was likely a Sarmat. The silo used for the test, located at the Dombarovsky air base in Orenburg Oblast, had reportedly undergone urgent renovations starting in the spring of 2025. This upgrade, according to strategic armaments analyst Etienne Marcuz, suggests a preparation to support Sarmat tests, especially following the destruction of the missile’s primary northern launch site in a catastrophic explosion the previous year.
"Work there began in Spring 2025, after the ice thawed," Marcuz noted on X. He added that the "urgent renovation" at Dombarovsky strongly supports the hypothesis that the accident involved the Sarmat, rather than the older R-36M2, which hasn’t been tested in over a decade. Pavel Podvig, a senior researcher at the United Nations Institute for Disarmament Research and a keen observer of Russia’s nuclear forces, echoed this sentiment. He pointed out that the Rocket Forces would be highly unlikely to test the aging R-36M2, given its approaching retirement and the uncertainty surrounding its maintenance, particularly after Ukraine’s role in its upkeep ceased in 2014. This leaves the Sarmat as the only plausible candidate for recent tests.
Implications for Russia’s Deterrence and Military Readiness
If indeed another Sarmat failure, this latest incident is deeply concerning for Russia’s long-term deterrence capabilities. The aging R-36M2 fleet carries a substantial portion of Russia’s strategic warheads, and any further delays in the Sarmat’s deployment push the timeline for their replacement further into the future. This reliance on increasingly obsolescent systems raises significant questions about the readiness and modernization of Russia’s nuclear arsenal.
Even before last week’s mishap, the Sarmat program had faced considerable delays, with its entry into service repeatedly pushed back since its initial 2018 target. The ongoing conflict in Ukraine has undeniably diverted significant Russian military resources and attention. Airplanes, artillery, drones, and troops are being consumed by the war, while the modernization of the strategic nuclear forces appears to have taken a backseat as the Kremlin focuses on replenishing assets crucial for the Ukraine campaign.
A Strategic Pivot? The Rise of Lighter Missiles
While the Sarmat struggles to get off the ground, Russia possesses an inventory of lighter ICBMs, such as the Yars missile, which are capable of carrying single warheads or multiple independently-targetable reentry vehicles (MIRVs). These systems, some of which utilize mobile launchers, offer greater operational flexibility and have a more proven track record. The Yars missile is reportedly scheduled for a test flight in the near future, as indicated by airspace warnings to civilian aviation.
Routine missile testing is a standard practice for nuclear powers like Russia and the United States, serving to ensure the readiness of their strategic forces. In the days leading up to the recent failed launch, a US Air Force RC-135S Cobra Ball surveillance plane was reportedly spotted in Alaska, a position ideal for monitoring ballistic missile tests conducted by Russia. These aircraft are equipped with advanced sensors to collect data crucial for arms control verification and the development of missile defense systems.
Future Uncertainties and Doubts
Just last month, President Putin declared that the Sarmat would undergo "combat trials" before the end of the year and be deployed on "combat duty" the following year. Friday’s failed launch, however, clearly demonstrates that the weapon is far from being combat-ready. The incident has intensified discussions among analysts about the viability of the Sarmat program. Some now openly question whether Russia might cancel the Sarmat altogether and instead rely on its existing, more reliable, and versatile arsenal of smaller ICBMs.
Dmitry Stefanovich, a Moscow-based Russian researcher, succinctly captured this sentiment on social media, suggesting that "Sarmat deserves to be canceled." This sentiment, echoing concerns about the missile’s persistent technical issues and the substantial resources it has consumed, highlights the growing doubts surrounding its future. The persistent failures of the Sarmat not only undermine Russia’s strategic posturing but also raise fundamental questions about the efficacy of its defense industrial base and its ability to deliver on ambitious technological promises.
The Wider Context: War, Resources, and Technological Aspirations
The Sarmat’s struggles are intrinsically linked to the broader context of Russia’s ongoing military engagement. The protracted conflict in Ukraine demands immense resources, stretching the Kremlin’s industrial and financial capacities thin. While Putin continues to leverage his strategic arsenal in his rhetoric to deter Western involvement in Ukraine, the reality on the ground suggests a strain on the very modernization programs intended to bolster that arsenal.
In essence, the development of a cutting-edge weapon system like the Sarmat requires sustained investment, advanced technological expertise, and stable testing environments – all of which are undoubtedly impacted by the demands of a large-scale conventional war. The recurring failures of the Sarmat serve as a potent reminder that technological ambition, especially in the realm of complex weaponry, is a delicate dance with engineering realities, resource allocation, and geopolitical pressures. The future of Russia’s strategic deterrence may very well hinge on its ability to overcome these formidable challenges or to adapt its strategy to the capabilities of its more established, yet less flashy, missile systems.
This saga of the Sarmat missile is more than just a technical post-mortem; it’s a window into the pressures and priorities of a nation at war, grappling with the immense challenge of maintaining and modernizing its most powerful deterrents in the face of significant operational and developmental hurdles. The West, while perhaps taking some comfort in these apparent setbacks, remains watchful, aware that even troubled programs can eventually yield formidable capabilities.
