Level 1 — Absolute Beginner
Russia tested a very big rocket. It is a missile. The missile is called Sarmat. It can travel a long way.
President Vladimir Putin spoke on TV. He said the missile is the strongest in the world. He is happy with the test.
The test was on May 12. The rocket left a place called Plesetsk. The rocket did not hurt anyone. It was only a test.
Russia wants to use the missile soon. The first group of missiles will be ready by the end of the year.

Level 2 — Elementary
On May 12, 2026, Russia successfully launched a new and very powerful missile called the RS-28 Sarmat. The test happened at the Plesetsk Cosmodrome in northwestern Russia.
President Vladimir Putin told the country that this missile is the strongest in the world. He said the combined power of its warheads is much greater than any Western missile.
The missile is called 'Satan 2' in the West. It can travel more than 18,000 kilometers and reach almost any place on Earth. It can carry many nuclear weapons at the same time.
Russia plans to put the first group of Sarmat missiles into service before the end of the year. They will be based in a region called Krasnoyarsk in Siberia.

Level 3 — Intermediate
Russia announced on May 12, 2026, that it had successfully test-launched the RS-28 Sarmat, a heavy intercontinental ballistic missile that has been in development for more than a decade. The launch took place at the Plesetsk Cosmodrome at 11:15 a.m. Moscow time, and the dummy warheads landed at the Kura test range in Kamchatka.
President Vladimir Putin addressed military commanders shortly after the test. He described the Sarmat as 'the most powerful missile in the world' and said its combined nuclear payload is more than four times greater than that of any Western counterpart. Putin also stated that the weapon can fly along both traditional ballistic and suborbital trajectories.
The Sarmat, dubbed 'Satan 2' by Western analysts, has had a troubled history. Earlier tests ended in failure, including a catastrophic silo explosion at Plesetsk in 2024. Successful tests have therefore become important political moments for the Kremlin, especially while Russia is still entangled in a difficult ceasefire with Ukraine and ongoing tension with NATO.
Defense officials confirmed that the first Sarmat regiment will be stationed at Uzhur, in the Krasnoyarsk region of Siberia, before the end of 2026. NATO governments have urged caution, warning that new Russian strategic weapons will affect arms-control negotiations, which have stalled since the suspension of the New START treaty.

Level 4 — Advanced
Russia's long-delayed RS-28 Sarmat strategic missile, dubbed 'Satan 2' in Western parlance, finally registered an unambiguously successful test on May 12, 2026, when it was fired from a hardened silo at the Plesetsk Cosmodrome shortly after 11 a.m. Moscow time. The vehicle traversed its programmed trajectory across the breadth of Eurasia and deposited dummy reentry vehicles at the Kura impact range on the Kamchatka Peninsula. Russian state television, in a meticulously timed broadcast, showed President Vladimir Putin congratulating his Strategic Missile Forces commanders and declaring that the Sarmat now represents 'the most powerful missile in the world.'
Putin's characterization, while predictably superlative, is not entirely without substance. The Sarmat is engineered to deliver as many as ten heavy nuclear reentry vehicles or a swarm of MIRVed hypersonic glide bodies, including the elusive Avangard. Crucially, its capacity to fly suborbital trajectories — effectively a fractional orbital bombardment system — would allow it to approach North American targets via the South Pole, complicating early-warning radar coverage that is largely oriented across the Arctic. Strategic analysts at IISS and RUSI have long argued that fielding the Sarmat will require Washington to rethink its missile-defense architecture, particularly the Ground-Based Midcourse Defense system in Alaska.
The Sarmat program has been anything but smooth. Conceived in 2009 to replace the Soviet-era R-36M2 Voevoda, the missile suffered repeated propellant-loading anomalies and culminated in a catastrophic silo explosion in late 2024 that levelled a launch position at Plesetsk and prompted Western analysts to question whether the system would ever achieve initial operational capability. Tuesday's flight test therefore reads less as a milestone in pure engineering than as a political signal: amid a fragile ceasefire with Ukraine, an unresolved confrontation in the Strait of Hormuz, and the lapse of nuclear arms-control treaties, the Kremlin appears determined to demonstrate that its strategic deterrent remains modern and credible.
Defense ministry officials confirmed that the first regiment, comprising approximately a dozen Sarmat silos, will be combat-ready at the Uzhur garrison in the Krasnoyarsk region before the end of 2026. The deployment is expected to coincide with the formal lapse of the moribund New START treaty, which has imposed a ceiling of 1,550 deployed strategic warheads on each side since 2010. Without a successor agreement, Western governments warn, the world risks slipping into an unrestrained nuclear competition reminiscent of the early 1980s — a context in which any successful Sarmat test inevitably carries a heavier political charge than the metallurgy alone would suggest.
