Russian frigate flares passed within metres of a Danish military helicopter over the Baltic Sea on 14 September 2026. The Danish defence command said the warship fired two flares towards a Fennec helicopter in international waters off Gedser, at the southern tip of the island of Falster, with one narrowly missing the aircraft. No warning and no radio contact preceded the firing.
The helicopter was on a routine mission to photograph the frigate — an activity NATO members conduct regularly and which Russia conducts in return.
What the Danish military described
The account from Copenhagen is specific on the two points that matter for assessing intent: the absence of any prior communication, and the proximity. Flares are a recognised signalling and countermeasure device; fired towards an aircraft at close range and without warning, they present a genuine hazard to a helicopter’s engines and crew. Defense News reported the Danish account the following day.
Denmark has also said this is not isolated, reporting repeated Russian naval provocations in its straits — waterways that control access between the Baltic and the North Sea and through which a great deal of Russian seaborne trade passes.
Moscow’s version
Russia’s account inverts the sequence. Moscow accused Denmark of carrying out “dangerous manoeuvres” near its ship and said it was investigating the incident. Russia’s ambassador in Copenhagen, Vladimir Barbin, attributed the near miss to the Danish aircraft’s conduct. Al Jazeera reported the exchange of warnings between the two governments.
Both accounts come from parties with an interest in the finding, and no independent verification of the distance or the sequence has been published. What is not disputed is that flares were fired and that an encounter took place in international waters.
Why the Baltic keeps producing these encounters
Geography does most of the work. The Baltic is narrow, heavily trafficked, and ringed almost entirely by NATO members since Finland and Sweden joined. Russian naval and commercial vessels transiting to and from the Gulf of Finland pass close to allied territory as a matter of routine, and allied aircraft photograph them as a matter of routine. The margin for misjudgement is measured in minutes.
Since 2022 the region has accumulated a catalogue of incidents: gas pipeline outages, airspace violations, drone sightings, and damage to undersea cables. Each has been individually deniable. Collectively they describe a pattern of pressure applied below the threshold that would trigger a collective response.
The escalation question
The risk in encounters of this kind is not that either government wants a confrontation. It is that a flare that misses by metres could, on another day, not miss — and that the political machinery for de-escalating a shoot-down is considerably slower than the machinery for causing one.
This sits alongside the broader confrontation traced in our reporting on the EU’s renewal of Russia sanctions and on the domestic politics behind it in our coverage of the Russian State Duma election. Diplomatic attention is meanwhile concentrated in New York, as set out in our preview of the UN General Assembly high-level week.
Denmark’s particular exposure
Denmark sits on the gateway to the Baltic. The Danish straits — the Great Belt, the Little Belt and the Oresund — are the only sea route between the Baltic and the North Sea, and they are shallow, narrow and busy. Every Russian vessel moving between the Gulf of Finland and the wider ocean passes through waters Denmark monitors.
That geography makes surveillance a standing obligation rather than a provocation, and it makes Danish forces the ones most frequently in close proximity to Russian ships. It also explains why Copenhagen has been reporting a pattern rather than a single event.
The straits carry an additional complication: a substantial volume of sanctioned oil moves through them aboard vessels of uncertain registration and insurance. Monitoring that traffic is a separate task from military surveillance, but it is performed in the same waters by the same small navy, which raises the number of encounters overall.
What to expect now
Denmark will make a formal protest and will almost certainly raise the incident with NATO allies; Russia will complete an investigation that concludes its vessel acted properly. Neither outcome changes the underlying situation. The practical question is whether the allies adjust their surveillance procedures — greater standoff distance, different notification protocols — which would reduce risk while conceding a small amount of the freedom of navigation the flights are partly intended to assert.
Background questions
What happened between the Russian frigate and the Danish helicopter?
A Russian frigate fired two flares towards a Danish military helicopter in international waters off Denmark on 14 September 2026. One passed within what the Danish military described as a matter of metres.
Where did the incident take place?
Off Gedser, at the southern tip of the island of Falster in southern Denmark, in international waters.
What was the Danish helicopter doing?
The Fennec helicopter was on a routine mission to photograph the Russian frigate, according to the Danish defence command.
Was any warning given?
The Danish military said no warning and no radio contact preceded the firing of the flares.
How has Russia responded?
Moscow accused Denmark of carrying out dangerous manoeuvres near its ship and said it was investigating. Russia’s ambassador in Copenhagen, Vladimir Barbin, placed blame on the Danish aircraft.
Why is the Baltic Sea considered high risk?
The region has seen gas pipeline outages, airspace violations and drone sightings since Russia’s full-scale invasion of Ukraine in 2022. Denmark has reported repeated Russian naval activity in its straits.
