Four times in a single week, NATO fighter jets roared off the runway at Siauliai Air Base in Lithuania to intercept Russian military aircraft flying over the Baltic Sea. The scrambles, covering April 13 to 19, 2026, targeted Tu-22M3 long-range bombers and Su-30 fighters that were flying without filed flight plans, with transponders switched off, and ignoring all radio contact, according to Lithuania’s Ministry of National Defence.
The week before was even busier. Between April 6 and 12, allied jets launched five times to shadow Russian planes, including an IL-20 reconnaissance aircraft, Su-30SM fighters, and an An-26 transport. That brings the two-week total to nine intercepts, one of the most intense stretches of NATO Baltic Air Policing activity since Russia’s full-scale invasion of Ukraine in 2022.
Lithuania’s Defence Ministry described the flights as a persistent violation of international aviation norms, noting in its weekly summary that every intercepted aircraft was operating without a transponder signal, without a pre-filed flight plan, and without any radio communication with regional air traffic control. “These are not isolated events,” a ministry spokesperson said in a published briefing accompanying the April data, underscoring the cumulative strain on allied readiness.
A pattern that predates spring
The surge did not appear out of nowhere. Lithuanian government records from November 2025 show three scrambles during the week of November 17 to 23, involving IL-20, Tu-134UBL, and Su-30 aircraft. Every flight featured the same trio of violations: no transponder, no flight plan, no radio communication. By late 2025, Russian crews had already normalized flying in ways that make them invisible to civilian air traffic control and harder for NATO early-warning systems to classify quickly.
What has changed since then is the tempo. Moving from three scrambles in a November week to five and then four in consecutive April weeks suggests either a deliberate escalation in Russian flight activity or a shift in the types of missions being flown near Baltic airspace, or both.
The Kaliningrad incursion
One episode stands apart from the broader pattern. The Lithuanian Armed Forces stated that two Russian aircraft approaching from the direction of Kaliningrad crossed into Lithuanian sovereign airspace, not merely the international airspace over the Baltic Sea where most intercepts occur. Spanish Eurofighter Typhoons, serving as the alert detachment at Siauliai at the time, scrambled, intercepted the aircraft, and escorted them out.
A caveat is necessary here: the Lithuanian Armed Forces confirmation has been referenced in official communications, but no standalone public link to the original statement or a precise date for the incursion has been made available. Lithuania has also not disclosed the duration or depth of the penetration, so it remains unclear whether the incursion was a brief navigational deviation or a deliberate probe of allied response thresholds. That distinction carries very different implications for escalation risk. Entering a NATO member’s sovereign airspace is a qualitatively different act from flying through international corridors without a flight plan, forcing national authorities to weigh territorial defense and potential rules of engagement.
What the aircraft tell us
The specific planes involved matter. The Tu-22M3 is a supersonic strike platform whose ability to carry anti-ship and nuclear-capable cruise missiles is well documented in open-source military references and has been acknowledged by Russian defense officials over many years. Its appearance near Baltic airspace signals a different order of capability than a transport or surveillance flight. Su-30 and Su-30SM fighters, also identified in the intercepts, are advanced multirole combat jets typically used to escort bombers or fly their own combat air patrols. Paired together, these aircraft form packages that resemble wartime strike formations more than routine training sorties.
NATO has run Baltic Air Policing rotations since 2004, with allied nations cycling fighter detachments through Siauliai and Estonia’s Amari Air Base. Intercepts of Russian aircraft in international airspace are not new. But the combination of rising frequency, heavier aircraft types, and the broader confrontation between Russia and the West since the invasion of Ukraine gives these encounters a sharper edge.
Gaps in the public record
Lithuania’s weekly summaries are the most granular public data available on Baltic intercepts. They confirm aircraft types, rule violations, and scramble counts. What they do not include are precise flight paths, altitudes, or distances from Baltic coastlines. Without that detail, outside analysts cannot determine whether individual flights were probing specific radar gaps, testing response times at particular sectors, or simply transiting between Russian bases in Kaliningrad and the mainland. A bomber on a straight, predictable route at cruising altitude looks very different from one making repeated course changes near a national boundary.
No NATO-wide aggregation of 2026 Baltic intercept data has been released publicly. The Lithuanian reports cover only the Baltic Air Policing mission’s area of responsibility. Russian air activity near Norway, Poland, or the Black Sea is tracked by different allied commands, and no consolidated count exists in the open domain. That makes it hard to judge whether the Baltic spike reflects a broader increase in Russian military aviation or a localized shift in Moscow’s approach to this corridor.
Russia’s intent is the largest unknown. The Kremlin has not publicly addressed the specific flights Lithuania has cataloged. Russian officials have previously characterized such missions as routine training, but consistently flying without transponders and ignoring radio calls goes well beyond what any state treats as normal peacetime operations. Whether these sorties are centrally directed provocations, realistic combat training, or a mix of both cannot be determined from the available records alone.
What the scramble count means for allied readiness
Nine intercepts in two weeks impose real costs on allied air forces even if no shots are fired. Each scramble burns fuel and flight hours, accelerates engine and airframe wear on fighters that NATO nations also need for other commitments, and keeps ground crews working at surge tempo. For smaller allied air forces rotating through Siauliai on four-month deployments, that operational grind adds up fast.
The political cost is harder to measure but no less real. Every scramble reinforces the message that Russia is willing to test the boundaries of acceptable military behavior along NATO’s border, keeping Baltic governments and their populations in a persistent state of alertness. Moscow has not spelled out its objectives, but the pattern itself functions as sustained pressure, one that demands allied attention, resources, and resolve whether or not it ever escalates further.
