Russia Tests P-800 Oniks and Kh-35 Anti-Ship Missiles in Baltic Sea Drill Simulating Naval Strikes.

Russia’s Baltic Fleet activated Bal and Bastion coastal missile systems in a Baltic Sea drill simulating the destruction of enemy surface ships. The exercise reinforces Moscow’s anti-access strategy along NATO’s northeastern maritime approaches.

The training involved 3K60 Bal systems armed with Kh-35 missiles and 3K55 Bastion launchers firing P-800 Oniks supersonic anti-ship weapons under simulated combat conditions. Units practiced target detection, engagement coordination, and rapid redeployment along coastal sectors. While no live launches were confirmed, the scenario replicated saturation strikes against a naval detachment, a core element of Russia’s layered coastal defense doctrine in the Baltic region.

Missile units advanced in combat vehicles toward designated firing positions, where both systems were rapidly deployed in a configuration consistent with real engagement scenarios. After receiving target designation data, crews executed electronic launches against simulated naval targets, reproducing the full engagement cycle without live munitions. In parallel, personnel verified the operability of onboard systems and conducted loading and unloading procedures, underscoring the logistical dimension of sustained coastal defense operations.

The Bal coastal defense missile system, developed by the Design Bureau of Mechanical Engineering (KBM), is designed to counter light and medium surface combatants operating in littoral zones. It relies on the Kh-35 anti-ship missile, a subsonic sea-skimming weapon measuring approximately 4.4 meters in length and weighing around 520 kilograms at launch. Powered by a turbojet engine, the Kh-35 cruises at about Mach 0.8 and descends to altitudes of 10 to 15 meters during its terminal phase, reducing detection by shipborne radar. Its standard range is around 120 kilometers, while the upgraded Kh-35U extends this to roughly 260 kilometers. The missile combines inertial navigation for mid-course guidance with an active radar seeker for terminal homing, allowing it to engage maneuvering targets in cluttered maritime environments.

Complementing this capability, the Bastion coastal defense missile system employs the P-800 Oniks 3M55 (SS-N-26 Strobile), also known in export form as Yakhont, a supersonic cruise missile developed by NPO Mashinostroyeniya. Entering service in the early 2000s, the missile measures about 8.6 meters in length with a launch weight close to 3,000 kilograms. It uses a solid-fuel booster followed by a kerosene-fueled ramjet engine, enabling sustained speeds between Mach 2 and Mach 2.2. Depending on its flight profile, the missile can reach up to 300 kilometers in a high-altitude trajectory, while a low-altitude sea-skimming mode reduces range but improves survivability against radar detection.

The P-800 Oniks 3M55 (SS-N-26 Strobile) integrates a dual guidance system combining inertial navigation with an active radar seeker, supplemented by a passive mode capable of homing on emitting radar systems. Later variants incorporate an imaging infrared seeker, improving accuracy against small or low-signature targets. Its semi-armor-piercing warhead, weighing around 250 kilograms, is designed to inflict critical damage on heavily protected vessels, including large surface combatants. The missile’s versatility allows deployment from ships, submarines, aircraft, and ground-based systems such as Bastion-P, reinforcing its role as a core component of Russia’s anti-ship strike architecture.

Both Bal and Bastion systems are mounted on high-mobility MZKT chassis, enabling rapid redeployment along coastal corridors and enhancing survivability through dispersion. Their architecture includes command-and-control vehicles and targeting interfaces capable of integrating external data from surveillance assets or radar networks. This connectivity allows coordinated salvos and extends engagement capacity beyond organic sensor ranges, a key factor in contested electromagnetic environments such as the Baltic Sea.

The combined use of these systems reflects a layered coastal defense doctrine. Bal units, equipped with Kh-35 missiles, are optimized for engaging dispersed or smaller targets, including patrol vessels and amphibious elements approaching shorelines. Their subsonic speed is offset by low-altitude flight and the ability to launch multiple missiles in quick succession, saturating defensive systems. Bastion units, equipped with the P-800 Oniks 3M55 (SS-N-26 Strobile), provide long-range strike capability against high-value targets such as destroyers or amphibious assault ships. The missile’s supersonic speed and terminal sea-skimming phase, at altitudes as low as 10 to 15 meters, complicate interception and reduce reaction time for defensive systems.

The Baltic Fleet’s press service stated on March 23, 2026, through TASS, that the exercise included system checks and weapon handling drills in addition to simulated engagements, highlighting a comprehensive approach to operational readiness. Such activities indicate sustained emphasis on maintaining both technical reliability and crew proficiency within coastal missile units.

These maneuvers take place in a region where maritime access and control remain highly contested. The Baltic Sea’s confined geography amplifies the impact of coastal missile systems capable of rapidly influencing naval operations. By maintaining and exercising capabilities centered on the Kh-35 and P-800 Oniks 3M55 (SS-N-26 Strobile), Russia reinforces an anti-access posture that complicates NATO naval planning and raises the operational threshold for deployments near its coastline. As regional actors continue to adapt their force posture and surveillance capabilities, the interaction between access and denial systems remains a defining feature of the evolving security environment in Northern Europe.
