RAF Typhoons Test Europe’s 2026 Ukraine Security Guarantee

Europe is rehearsing a postwar mission in Ukraine before anyone can say with confidence that the war is ending. That is the point of Exercise Koalicja 26.2, which begins on 9 November across Poland, France and Turkey. Britain and France are putting 2,800 troops from 11 countries through the first major exercise of the Multinational Force-Ukraine, or MNF-U. The exercise is not a peacekeeping drill. It is a test of whether European governments can turn a political promise into a force that could actually arrive, operate and survive in Ukraine.

That distinction matters. European leaders have spent months discussing security guarantees in language that sounds firm until someone asks who will move the troops, protect the supply lines, control the airspace and clear the Black Sea. Koalicja is the first visible attempt to answer those unglamorous questions.

A Force Built Around Practical Tasks

According to the British Ministry of Defence, the exercise runs from 9 to 22 November and will rehearse how to move, protect and supply a multinational force after the fighting stops. The United Kingdom is sending 300 personnel, including soldiers from the Army’s 7th Light Mechanised Brigade, known as the Desert Rats. RAF Typhoons and a Voyager refuelling aircraft will simulate the air component, including the reassurance of commercial aviation if Ukrainian skies reopen.

The participating countries are Belgium, Estonia, France, Germany, Lithuania, the Netherlands, Poland, Spain, Sweden, Türkiye and the United Kingdom. Poland will manage the movement of MNF-U forces after the war, while nearly 2,000 Polish soldiers will take part in the exercise itself. The arrangement is revealing: Warsaw is willing to make its territory the logistical hinge of the mission, but it is not promising to send its own troops into Ukraine.

France is contributing hundreds of troops and a unit equipped with roughly 50 contact drones, while Türkiye will establish the maritime element in Istanbul. That maritime work includes rehearsing mine clearance so commercial shipping can return safely to Ukrainian ports. The mission’s possible tasks also include protecting critical infrastructure, training Ukrainian forces and helping defend the skies.

The Real Test Is Command and Control

The most important part of Koalicja may be the least photogenic. The British release says the exercise will test command-and-control arrangements, the movement of equipment and supplies, and the integration of different components into a single multinational force. Those are precisely the areas where European military cooperation tends to look better on paper than on a map.

A British brigade, French drones, RAF aircraft and a Turkish maritime component are not automatically a coherent military instrument. They use different communications systems, rules of engagement and national approval chains. If a convoy is delayed, a drone unit loses its data link or an air mission requires urgent political clearance, the force will discover whether its headquarters is real or merely ceremonial.

This is why the MNF-U’s status outside NATO is politically useful and operationally awkward. It avoids forcing the alliance to take responsibility for a mission that Moscow has already described as unacceptable. It also means the coalition must build its own procedures, authorities and sustainment system. The force is supposed to enter only after a ceasefire and at Kyiv’s request. It will not monitor the ceasefire or conduct classic peacekeeping.

Europe’s Deterrence Problem Has Not Disappeared

Calling the mission postwar does not make the threat postwar. Russia’s President Vladimir Putin has rejected a foreign troop presence in Ukraine and warned that Western forces deployed there could be legitimate targets. Russian strikes are still hitting Ukraine’s power network, according to the BBC, even as negotiators prepare for talks in Abu Dhabi. A ceasefire, if one comes, would not erase Russia’s ability to threaten the force from outside Ukraine.

The coalition therefore faces a difficult contradiction. It wants to reassure Ukraine that a renewed Russian attack would trigger a European response, but it does not want to create a deployment that looks like an offensive commitment against Russia. The answer so far is carefully limited language: the MNF-U supports the Ukrainian army, protects infrastructure and helps regenerate Ukrainian forces. That may be enough for a political opening. It is not yet a deterrent plan.

The scale problem is even more uncomfortable. Britain and France have each indicated they could contribute about 5,000 troops. Yet a Center for Strategic and International Studies assessment cited by Defense News estimated that even a minimal tripwire presence could require 10,000 to 25,000 troops. Once rotations, force protection, air defence, logistics and medical support are counted, the headline number rises quickly.

Why This Exercise Still Matters

Europe is right to rehearse now. Waiting for a signed peace agreement would guarantee that the force exists only in speeches when the first crisis arrives. Koalicja can expose gaps while there is still time to fix them: who supplies air defence, who protects headquarters, who pays for the rotations, and who has authority to respond if a supposedly postwar mission is attacked?

But the exercise should not be confused with proof that Europe has solved the Ukraine problem. The absence of American troops is the clearest signal. European governments are trying to demonstrate strategic responsibility while the United States remains outside this particular rehearsal. That is a useful test of European capacity, but it is also a warning that the continent may have to carry a mission designed around a war it did not start and a security guarantee Washington may not underwrite.

Koalicja 26.2 will show whether 11 nations can move a force together. The harder question is whether they can keep it supplied, politically protected and militarily credible after the first Russian pressure campaign. Europe is finally practising the guarantee. It has not yet proved that it is willing to pay the price of making it believable.
