NATO Air Policing Missions Over the Baltic Sea: Routine Interceptions of Russian Aircraft Amid Elevated Tensions

Apr 24, 2026, 11:25

Introduction

NATO fighter jets, specifically French Rafale and Romanian F-16 units based at Šiauliai Air Base in Lithuania, have been carrying out regular interception missions against Russian military aircraft flying in international airspace over the Baltic Sea. These missions are part of NATO''s Baltic air-policing rotation. They take place amid increased tensions between NATO and Russia after Russia''s full-scale invasion of Ukraine.

Main Body

The French and Romanian detachments arrived in April 2024 for four-month rotations under NATO command. Their main job is to identify and monitor Russian aircraft that do not follow International Civil Aviation Organization (ICAO) rules – specifically, flights without active transponders, filed flight plans, or radio contact with air traffic controllers. According to Colonel Mihaita Marin, commander of the Romanian F-16 unit, such non-compliance happens often, either on purpose or by accident. As a result, NATO must scramble jets to check the aircraft''s identity and peaceful intent. He noted that interceptions are happening almost daily and are expected to increase with better spring weather. On a recent Monday, French Rafale jets were scrambled to intercept a pair of Russian Tu-22M3 strategic bombers. Each bomber carried supersonic anti-ship missiles (a type also used in Ukraine and capable of carrying nuclear warheads). They were escorted by Su-30 and Su-35 fighters. The Russian formation took off from an airbase near St. Petersburg and flew a four-hour route in international airspace. It passed near the coasts of Finland, Estonia, Latvia, Lithuania, and Poland, then turned back as it approached Denmark. The French detachment reported that the Russian aircraft did not have transponders active, did not file flight plans, and did not establish radio contact. In addition, fighter jets from Sweden, Finland, Poland, Denmark, and Romania also launched to monitor the flight. NATO did not comment on the incident. Lieutenant Colonel Alexandre, commander of the French Rafale wing (his surname was not given for security reasons), stated that the reasons for Russian pilots'' behavior are unclear – whether it is a lack of professionalism or a deliberate test of NATO''s response procedures. He emphasized that each situation requires a NATO response, because ignoring such flights would be unacceptable. The French commander described the interactions as mutual observation and scrutiny, with both sides keeping distance and avoiding escalation. The main goal of these air-policing missions, according to commanders, is to deter rather than to provoke. They provide reassurance to the Baltic states (Estonia, Latvia, Lithuania), which do not have their own air forces to defend against possible Russian aggression.

Conclusion

NATO''s Baltic air-policing operations continue as a routine but important way to monitor Russian military aviation activity in the region. The alliance keeps a constant presence through rotating detachments. The current French and Romanian units are scheduled to hand over to Italian forces in August. The number of interceptions is expected to increase further as weather improves. This shows the ongoing state of alert needed to manage the risk of accidental escalation between NATO and Russia.

Sentence Learning

Their main job is to identify and monitor Russian aircraft that do not follow International Civil Aviation Organization (ICAO) rules – specifically, flights without active transponders, filed flight plans, or radio contact with air traffic controllers.
This sentence uses a relative clause ("that do not follow...") to specify which aircraft are being monitored. The relative clause provides essential information about the aircraft, making the sentence more precise.這個句子使用了關係從句（「that do not follow...」）來具體說明被監控的飛機。關係從句提供了關於飛機的必要資訊，使句子更精確。
On a recent Monday, French Rafale jets were scrambled to intercept a pair of Russian Tu-22M3 strategic bombers.
This sentence uses the passive voice ("were scrambled") to focus on the action (the scrambling) rather than the agent (who scrambled them). It is common in formal reporting to emphasize the event.這個句子使用了被動語態（「were scrambled」）來強調動作（緊急起飛）而非執行者（誰下令起飛）。在正式報導中常用被動語態來突出事件。
Lieutenant Colonel Alexandre, commander of the French Rafale wing (his surname was not given for security reasons), stated that the reasons for Russian pilots' behavior are unclear – whether it is a lack of professionalism or a deliberate test of NATO's response procedures.
This sentence contains a passive construction ("was not given") and a linking word pair ("whether...or") to present two alternative possibilities. The passive voice adds formality, and the "whether...or" structure clearly contrasts the two potential explanations.這個句子包含被動結構（「was not given」）和一組連接詞（「whether...or」）來提出兩個可能性。被動語態增加正式感，而「whether...or」結構清楚對比了兩種可能的解釋。
They provide reassurance to the Baltic states (Estonia, Latvia, Lithuania), which do not have their own air forces to defend against possible Russian aggression.
This sentence uses a non-restrictive relative clause ("which do not have...") to add extra information about the Baltic states. The clause is set off by commas and provides context for why reassurance is needed.這個句子使用了非限制性關係從句（「which do not have...」）來補充關於波羅的海國家的額外資訊。從句由逗號分隔，提供了為何需要安撫的背景。
The number of interceptions is expected to increase further as weather improves.
This sentence uses the passive voice ("is expected") to report a prediction without specifying who expects it. The linking word "as" shows a cause-and-effect relationship between improving weather and increasing interceptions.這個句子使用了被動語態（「is expected」）來報告預測，而不指明誰預測。連接詞「as」顯示了天氣改善與攔截次數增加之間的因果關係。
