Estonia has accused Russia of mounting its most aggressive airspace incursion of the year after three MiG-31 fighter jets crossed into Estonian skies on 19 September and remained for around 12 minutes before being intercepted by NATO aircraft.

The jets entered over the Gulf of Finland with their transponders switched off, according to Estonian media, and flew close to Tallinn before Italian F-35s scrambled to intercept.

NATO spokesperson Allison Hart confirmed the response, describing the incident as “yet another example of reckless Russian behaviour and NATO’s ability to respond.”

Estonian Foreign Minister Margus Tsahkna summoned Russia’s chargé d’affaires in Tallinn to issue a formal protest, calling the incursion “unprecedentedly brazen.” He added that “Russia has already violated Estonia’s airspace four times this year, which in itself is unacceptable. But today’s violation must be met with a swift increase in political and economic pressure.”

NATO launches Eastern Sentry after Russian drone incursions

The incident follows a pattern of recent Russian activity across NATO’s eastern flank. On 10 September, more than a dozen drones entered Polish airspace, prompting Warsaw to invoke Article 4 of the NATO treaty. Polish Prime Minister Donald Tusk described that episode as “an unprecedented violation of Polish airspace” and warned it brought Europe closer to open conflict. Romania has also reported Russian drones entering its airspace this month, with fragments from earlier strikes in Ukraine repeatedly landing on Romanian territory.

Estonia has responded by launching unplanned military exercises to test its readiness for further violations. Lieutenant General Andrus Merilo, Commander of the Estonian Defence Forces, said the drills reflect growing concerns over Russian tactics, adding that “resupply, readiness, and rapid response must all be tested under the assumption that airspace incursions will continue.”

The European Union also tied the incident to its wider sanctions policy. Commission President Ursula von der Leyen said on 19 September that “again and again, President Putin has escalated, and in response, Europe is increasing its pressure,” as Brussels unveiled new restrictions targeting Russian energy and financial transactions.

NATO warplanes scramble due to potential Russia threat

Russia has not commented publicly on the Estonian violation. With NATO reinforcing its air posture under Operation Eastern Sentry, allied fighters from France, Germany, and Denmark are already on rotation in the region.

  1. They tried to shot down a RAF Rivet Joint a few years ago and fired two air to air missiles at our aircraft when it was in international airspace.Since then our Rivet Joints have had have a fighter escort. If we entered Russian airspace our aircraft would be fired at.

    • I remember that incident, 2023 I believe? There have been other occasions where aircraft have been threatened, and wasn’t a drone FUBAR’ed with jet fuel or whatever?

      With tensions as they are, 12 minutes before interception is shabby really. Some may of course say ’12 minutes, they were intercepted, they buggered off, so no harm done’. An acceptable outlook, considering a CAP would incur huge costs.

  2. So did they flee back to Russian airspace before NATO jets were in range to down them?
    The NATO response needs to be faster, though flying a constant CAP over NATO borders is going to cost a lot in terms of fuel and airframe lifespan.

    Is Russia testing NATOs responsiveness to incursions?
    Or is Russia hoping that such incursions will divert SAM batteries to Baltic nations instead of going to Ukraine.
    Or both?

    • I wonder if Russia is trying to provoke an incident to pander to the domestic audience and cover/hid the bad news coming out of Ukraine.

      • They don’t need an incident to feed to their domestic audience. The Kremlin completely controls all media in Russia, and have already convinced the population that they are fighting NATO forces.

        • True, but authoritarian nations can be very unpredictable in their geopolitical drivers..we think democracy can be chaotic..but the fear of offending the floating voter generally keeps democracies from going bonkers ( baring a few obvious exceptions).

    • I think you are proportioning some strategy to the Russian’s behaviour whereas we already know from their war in Ukraine that their air force cannot coordinate a unified air dominance strategy and it’s largest formation is a 4 jet unit sent to attack X target. Frequently missing said target.
      No I think this is Russia demonstrating it’s incompetence by provoking NATO. If these aircraft are within NATO Territorial airspace they should be challenged, warned and then if not adhering to the instructions then shot down. That is the law.
      What’s more worrying is we are one miscalculation away from a war and the UK has spent the last 3 years doing buggering all to prepare. Our armed forces continue to be cut at a time the opposite should be rapidly occuring.
      Our numbers of jets is appallingly low
      Our AWACS fleet virtually non existent
      Our frigate and destroyer fleet far too few and our submarine force a shrunken memory of what it should be.
      The Army is in an appalling mess and utterly unfit to face our enemies on the battlefield.
      Our GBAD is virtually non existent and we have a grand total of 14 Archer SPGs and a few dozen light 105mm guns and that’s it for artillery until RCH155 comes along sometimes next century.
      Warrior is outdated and outclassed and needs replacing
      Ajax is slowly coming into service late and massively over budget
      And we only have around 200 C2s left of which only 148 are going to be upgraded to C3 standard.
      In short utter bollocks and needs sorting out before we get militarily defeated by an opponent not afraid to invest in hard power.

  3. A 12 minute incursion into NATO airspace, with the tension levels as they are. You almost have to wonder if the Kremlin is looking to get one of its jets shot down.

    It would play well to the domestic audience, increase the fear of NATO and help Putins control of the population. The Pokrovsk offensive is going no place fast infact Ukraine has just made a pushback..so. Maybe Putin wants an anti western “hatred” story to cover the issue.

    • I think you are correct (again) Jonathan. This is the result of yet more failure on Putin’s part. He needs to provoke in order to obscure.

  4. It seems Russia May now be trying to buy back air defence systems it’s sold to other nations, it’s even trying too get Turkey to sell it the two S-400 systems back to it. This all smells a bit like Russia barking to hide its profound problems.

      • Or here is a better idea. Turkey just keeps them. Why would any NATO country sell military hardware to Russia. It shouldn’t.

        • I’d disagree, Ukraine needs all the air-defence batteries it can find. And while the S400 has proven to be nowhere near the hype, it should be able to deal with Iranian-designed drones.

      • That’s a good idea, Ukraine knows how to use them has the logistics in place, two more batteries of s-400 would be pretty significant.

  5. I wonder if Putin has told China and North Korea what is plans are ? IF he keeps playing this dangerous game it’s only a matter of time before a Mug or Flanker pilot get a NATO Missile inbetween is legs .Putin most realize he can’t win Ukraine by now he’ll never win a Conventional fight with NATO and of course if Nukes go off its curtains for the world ? Or is happy to live in is Bunker .
