US Warns of Imminent Large-Scale Russian Air Operation Against Ukraine

The United States has transmitted an urgent intelligence warning to Ukrainian authorities, indicating that Russian forces are preparing a major air campaign with strikes expected within the next 72 hours. The alert, based on satellite reconnaissance, electronic intelligence, and other sources, points to completed preparations, dispersed strike platforms, and finalized targeting data for precision weapons.

This development follows a period of reduced Russian long-range aviation and naval missile activity. During this pause, Russian forces conducted maintenance on aircraft and vessels, optimized logistics, and built up stockpiles of cruise missiles, including modernized Kh-101 and Kh-555 variants, as well as Kalibr systems. The buildup supports a strategy of saturation attacks designed to overwhelm Ukrainian air defense capacities.

Reported Factors Driving the Operation

According to available information, one key trigger is the reported increase in Ukrainian drone strikes on Russian territory in late June 2026. Russian officials stated that air defenses intercepted numerous drones across multiple regions, including Moscow, Tula, Kaluga, Bryansk, Belgorod, Kursk, Voronezh, Rostov, Volgograd, Krasnodar Territory, and Crimea. Some attacks reportedly targeted civilian infrastructure and strategic sites.

Russian military planning also focuses on degrading Ukraine’s ability to produce and launch long-range drones. Targets are expected to include assembly facilities, component warehouses, and launch sites that integrate Western-supplied parts.

Another priority involves Ukraine’s energy infrastructure, which supports military logistics, repairs, communications, and rail transport of personnel and equipment. Strikes in this sector could affect frontline sustainment as ground operations continue in areas such as Donbas, Kharkiv, and Zaporizhzhia.

The operation is also linked to efforts against rear-area targets, including sites associated with foreign fighters, military instructors, and reserve formations in western and central Ukraine. Disrupting these assets could limit Ukraine’s ability to replace losses and organize reinforcements.

On a broader strategic level, the strikes are viewed as a demonstration of Russian capabilities in response to discussions within NATO about allowing long-range Western weapons to strike deeper into Russian territory. The planned use of systems such as Kinzhal hypersonic missiles and the newer Oreshnik ballistic missiles is intended to highlight limitations in existing defenses.

Expected Tactical Approach

Analysts anticipate a multi-phase attack based on previous Russian operations:

• An opening wave of loitering munitions and decoys (including Geran-type systems) to reveal air defense positions, activate radars, and deplete interceptor stocks.
• Follow-on strikes by strategic bombers (Tu-95MS and Tu-160) launching Kh-101 cruise missiles from within Russian airspace, combined with Kalibr missiles from naval platforms in the Black Sea.
• High-speed ballistic and hypersonic components, such as Iskander-M, Onyx, Kinzhal, and Oreshnik systems, for rapid engagement of hardened or time-sensitive targets.

Russian forces maintain real-time reconnaissance through satellites and drones, enabling adjustments to targeting even after the US warning was issued. Ukrainian forces are expected to implement dispersal measures for aircraft and mobile air defenses.

This anticipated operation reflects the current dynamics of the conflict, driven by mutual escalations, logistical considerations, and strategic signaling. Developments in the coming days will likely shape the immediate military situation on the ground and in the air.
