Romania Wants NATO Gear in Black Sea

Romania arrives at this week's NATO summit in Ankara with a fairly blunt message: the Black Sea problem will not be solved by language. It needs radars, interceptors, ammunition and the roads, railways, ports and fuel lines that allow a military force to stay in the fight.

The reason sits in a treaty signed nearly 90 years ago. The Montreux Convention of 1936 gives Turkey control over warship passage through the Bosporus and Dardanelles, the narrow routes linking the Mediterranean to the Black Sea (Turkish MFA). That means NATO cannot simply sail a large fleet into the Black Sea whenever the mood in Brussels or Washington hardens. Turkey holds the gate.

That legal fact shapes Bucharest's position in Ankara. Romania is not asking NATO to notice the threat; NATO already calls Russia its most significant direct threat and describes the Black Sea as strategically important (NATO). What Romania wants is the equipment to make that assessment mean something on the ground and in the air (BTA, Moldpres).

Why the Black Sea is different

On the Baltic and Polish parts of NATO's eastern flank, the defence conversation is often about troops, bases and whether rail lines can carry heavy armour quickly enough. Romania needs all of that too. But it has an extra problem: reinforcement by sea depends on Turkey's reading of Montreux and its willingness to open the straits.

Carnegie Europe argues that Ankara has used a logic of "regional ownership" to keep Black Sea security centred on the three coastal NATO members, Turkey, Romania and Bulgaria, rather than encouraging a wider allied naval presence (Carnegie Europe). Bucharest's demand, then, is not simply for more allied soldiers. It is for a deterrence package designed around a geography where access is restricted by law as much as by distance.

The pressure is already showing. Drone incidents over or near Romanian territory during 2026 have exposed gaps in detection and response that current systems cannot properly close. Romania is ordering mobile Skyranger air-defence systems on Lynx armoured vehicles to deal with low-altitude threats (Truppendienst). Other eastern European allies are buying German IRIS-T medium-range interceptors (Zeit).

Buying a system, though, is not the same as having a working shield. Crews have to be trained. Ammunition has to be stocked. Maintenance chains have to exist. The systems have to be plugged into a command structure able to answer a basic question in seconds: when a drone enters NATO airspace, who sees it, who identifies it, and who has the authority to shoot?

What deterrence costs in practice

The first gap is detection. Romania needs sensors that can track low-flying drones and maritime threats before they become political incidents or military tests. Air and drone defence comes next, with Skyranger and IRIS-T forming part of that layer, but only if the equipment reaches the field with live munitions and spare parts.

At sea, the answer is different. Bulgaria, Romania and Turkey have expanded their trilateral mine-countermeasures group to include surveillance and the protection of underwater infrastructure (BNR). That model is practical because it works with Montreux rather than pretending the treaty is not there. It needs NATO intelligence-sharing and planning support, not a fleet that treaty law would keep out.

Then comes the unglamorous part that often decides whether deterrence is real: logistics. A proposed Turkey-Bulgaria-Romania fuel pipeline, along with better roads, rail links, ports and depots, would allow reinforcements to reach NATO's south-eastern flank and remain supplied once they arrive (wschodniaflanka.pl). Without that infrastructure, units may arrive late and run short quickly.

Other allies have reasons to care

Poland is not treating Romania's vulnerability as a regional side issue. Ahead of Ankara, the presidents of Poland, Lithuania, Latvia, Estonia and Romania coordinated a common position (rp.pl). Warsaw's calculation is straightforward: a stronger south-eastern flank gives NATO more routes, bases and supply options, reducing pressure on the Baltic corridor and the narrow Suwałki Gap.

Germany is making a related argument from the other end of the alliance. Chancellor Merz has framed the Ankara summit around Europe taking more responsibility inside NATO and delivering forces that can actually deploy, rather than promises that look grand on paper (Bundesregierung, Euronews).

That is the choice facing NATO in Ankara. It can put detection, air defence and logistics behind Romania's eastern-flank role, or it can issue another declaration and leave a member state waiting for the next drone incursion with little practical ability to stop it.
