A Turkish Navy vessel fires a mortar during a military exercise in April 2026 that included operations in the Black Sea and other maritime theaters surrounding the Turkish mainland. Abdullah Bozkurt/Stockholm Turkey is moving to the forefront of a NATO-backed multinational security initiative aimed at supporting Ukraine and strengthening Western influence in the Black Sea, marking what appears to be a significant departure from Ankara’s longstanding policy of limiting foreign military involvement in the strategically sensitive region. Recent correspondence from Defense Minister Yaşar Güler, a copy of which was obtained by Nordic Monitor, reveals that Turkey is playing a leading role in a multinational framework known as the “Coalition of the Willing for Ukraine,” a grouping of 33 countries preparing security arrangements for a potential postwar settlement between Russia and Ukraine. As part of the initiative, Ankara is establishing a Maritime Component Command in Istanbul’s Beykoz district overlooking the Bosporus, a development that could put Turkey at the center of future Black Sea security operations. According to Güler’s letter, dated May 18, 2026, the initiative is centered on the creation of a multinational operational headquarters known as the Multinational Force Ukraine (MNF-U), whose core command structure is being established in Paris. As part of the broader effort, Turkey has been tasked with planning and leading maritime security operations in the Black Sea. The proposed Maritime Component Command would be responsible for maintaining regional stability and preserving maritime security while respecting the restrictions imposed by the 1936 Montreux Convention. The project represents a notable evolution in Turkish policy. For decades Ankara has sought to preserve a delicate equilibrium between Russia and the West in the Black Sea, relying on the 1936 Montreux Convention to restrict the military presence of non-littoral powers and prevent the region from becoming a theater of direct confrontation between NATO and Moscow. Successive Turkish governments viewed the convention not only as a cornerstone of national sovereignty but also as an essential instrument for managing relations with Russia, a major supplier of energy and an important trading partner. A May 18, 2026, letter by Turkish Defense Minister Yaşar Güler indicates that preparations for a new NATO-backed multinational military facility in Istanbul are already well advanced, with operational planning, staffing and command arrangements actively being developed: Although Turkish officials insist that the new initiative will remain under national command and operate in full compliance with the Montreux Convention, the details disclosed by Güler suggest a much deeper level of integration with NATO planning than Ankara has previously accepted in the Black Sea. The defense minister disclosed that planning discussions already took place in Ankara on May 15-16, 2025, where participating countries agreed that Turkey would assume a leading role in the maritime dimension of the initiative and that all activities would be conducted within the legal framework established by the convention. Turkey has already begun implementing the project. According to the ministry a core staff composed entirely of Turkish personnel was established on August 25, 2025, to form the nucleus of the Maritime Component Command. Fourteen countries have since indicated their intention to contribute to the command structure, although participation in maritime operations will be limited to Black Sea littoral states, including Turkey, Romania and Bulgaria. The disclosure sheds new light on Ankara’s efforts to strengthen Black Sea security at a time when Russia’s war against Ukraine has transformed the strategic landscape of the region. Although Turkish officials emphasize that the initiative is not a NATO base and remains under national control, the project has attracted considerable attention because of its close coordination with NATO allies and its explicit focus on Ukraine. Turkey has historically resisted efforts to create permanent NATO military structures dedicated specifically to the Black Sea. During earlier debates over enhancing maritime cooperation in response to growing tensions with Russia, Ankara accepted intelligence-sharing and coordination through NATO’s Maritime Command (MARCOM) headquarters in Northwood, United Kingdom. However, it firmly opposed proposals for a standing NATO command focused exclusively on the Black Sea, warning that such a move could destabilize the region, provoke Moscow and undermine the delicate balance maintained under the Montreux regime. As a compromise, NATO established only a coordination cell at Northwood rather than a dedicated Black Sea headquarters. The arrangement enabled allies to exchange intelligence, maritime surveillance information and operational assessments without creating a permanent NATO military presence in the region. This approach reflected Turkey’s longstanding preference for preventing the Black Sea from becoming an arena of direct military competition between Russia and NATO while preserving its role as the principal guardian of the Montreux regime. The new Maritime Component Command linked to the Coalition of the Willing for Ukraine therefore represents a notable shift. Unlike earlier arrangements the initiative envisages a dedicated multinational command structure focused on Black Sea security and postwar support for Ukraine. Opposition lawmakers have questioned whether the new command structure could undermine Turkey’s longstanding policy of balancing relations between Russia and the West. Critics argue that despite assurances from the government, the initiative risks drawing Turkey more deeply into the Western security architecture at a time when Ankara continues to maintain extensive political, economic and energy ties with Moscow. Although Defense Minister Güler insisted that the initiative is not a NATO project and will remain under Turkish command, questions persist about the extent of NATO’s involvement. Once the headquarters becomes fully operational, it is widely expected to be integrated into NATO’s broader command and planning framework, given that the principal sponsors and participating countries are overwhelmingly NATO allies.

Further fueling such concerns are indications that key operational arrangements have already been discussed and refined with NATO involvement. These reportedly include issues related to Operational Command (OPCOM), Operational Control (OPCON), Area of Resposibility and the Terms of Reference (ToR) governing the mission. In NATO terminology, OPCOM and OPCON define the level of authority exercised over participating forces, while the Terms of Reference establish the mission’s mandate, responsibilities, chain of command and decision-making procedures. The apparent completion of planning work on these critical command-and-control mechanisms suggests that the initiative has advanced well beyond the conceptual stage. Critics therefore contend that regardless of official denials, the project increasingly resembles a NATO-backed structure designed to support Ukraine and strengthen the alliance’s posture in the Black Sea region. Such a development is likely to attract close scrutiny from Moscow, which has consistently portrayed Western-backed security initiatives in the Black Sea as efforts to contain Russian influence and expand NATO’s strategic footprint near its borders. Reports that French and British military officials have already visited the proposed headquarters site in Beykoz have further fueled speculation regarding the extent of Western involvement. Güler acknowledged the visits but stressed that the command would remain under Turkish authority and be headed by a Turkish general. He added that the multinational headquarters structure has not yet received formal approval and that the project remains in the planning phase. The documents also reveal that Ankara is moving forward with another major NATO-related initiative, the Multinational Corps Turkey (MNC-TUR), which is expected to be established in Adana. Opposition lawmakers argue that taken together, the Black Sea maritime command and the multinational corps signal a significant expansion of NATO’s military footprint in Turkey. Government officials, however, maintain that both projects are intended to strengthen collective security while preserving Turkey’s sovereign control over military activities on its territory. There is no doubt that the emergence of a permanent multinational maritime headquarters in Istanbul would become another source of friction in Turkey’s increasingly complex relationship with Russia. While Ankara has maintained political and economic ties with Moscow and continues to portray itself as a mediator, the newly disclosed plans show that Turkey is simultaneously preparing to play a leading military role in postwar security arrangements designed to bolster Ukraine and limit Russian influence in the Black Sea region.
