Russia test-fired the RS-28 Sarmat intercontinental ballistic missile on May 13, 2024, from the Kura missile test range in the Kamchatka Peninsula [1], [2].

The test serves as a strategic signal of military strength to NATO and the U.S. amid ongoing concerns regarding Russia's eastern flank. By demonstrating the operational capacity of its most powerful missile, the Kremlin aims to reinforce its nuclear deterrent ahead of national celebrations [2], [3].

Russian officials describe the RS-28 Sarmat, also known by the nickname “Satan II,” as the most powerful missile in the world [3], [4]. According to technical claims, the weapon possesses a range of 35,000 km [5]. This distance allows the missile to reach targets across the United States [3].

Russian officials said the missile cannot be intercepted by any existing air-defence system [6]. The test-fire occurred as the government prepared for the May 9 Victory Day parade, using the event to project power through the display of nuclear-capable weaponry [2].

The Kura range in Kamchatka provided the launch site for the flight [2]. The deployment of the Sarmat is part of a broader effort by President Vladimir Putin to modernize Russia's strategic nuclear triad—comprising land-based missiles, submarines, and bombers—to ensure the country can penetrate adversary defenses [3], [4].

The RS-28 Sarmat is described by Russia as its most powerful missile capable of reaching the United States.

The testing of the RS-28 Sarmat represents a calculated move by the Kremlin to maintain a 'credible' nuclear deterrent. By emphasizing a range of 35,000 km and claiming immunity to interception, Russia is attempting to negate the perceived advantage of U.S. missile defense systems. This escalation in rhetoric and capability underscores the volatile nature of strategic stability between nuclear-armed powers during periods of high geopolitical tension.
