The Finnish Defence Forces (FDF) issued a surprise NOTAM at 06:00 on Saturday, 18 July 2026, establishing a temporary no-fly and no-sail zone off the south-eastern port city of Kotka. The restricted area—coded EFR1772—extends from ground level up to flight level 660 and covers both airspace and adjacent territorial waters until 09:00. According to the FDF statement, the measure is a precautionary response to the risk of hostile or wayward drones entering Finnish airspace from the east. Maritime traffic was likewise asked to avoid the zone to ensure operational freedom for defence and border-guard units. The FDF’s action follows a string of drone-related alerts earlier in July and reflects growing concern about the spill-over of unmanned aerial activity from the war in Ukraine and from Russian electronic-warfare testing in the Gulf of Finland. Since Finland joined NATO in 2024, the nation has tightened situational awareness along its 1,300-kilometre eastern frontier and coastal approaches. Civil pilots were reminded in a May 2026 circular that restrictions can be activated with little notice and that pre-flight briefing must include the latest NOTAMs. For business aviation and scheduled airlines, the three-hour closure had limited immediate impact because most east-west traffic routings lie further south; however, operators of morning cargo flights and helicopter services serving offshore wind installations had to reroute or delay departures. Shipping agents reported minor diversions of container vessels awaiting berth in Kotka and Hamina harbours. While short, such pop-up restrictions highlight the importance for logistics planners of building time buffers into just-in-time supply chains that transit Finnish gateways. Border-security analysts note that Finland is simultaneously seeking €35 million in EU funds for permanent counter-drone sensors for the Border Guard. Companies sending staff to Finnish industrial sites near the eastern Gulf should ensure that travellers install the multilingual 112 Suomi emergency app and subscribe to real-time security alerts. Employers are also advised to review force-majeure clauses in service contracts covering potential drone-related closures of airspace or ports. Although Saturday’s restriction ended on schedule, officials cautioned that further short-notice measures remain possible throughout the summer holiday season. Travellers—especially general-aviation crews—should check NOTAMs up to engine start and maintain direct contact with air-traffic control when operating in south-eastern Finland.
