Bulgaria Signs at Ankara for Seven Belgian and Dutch Minehunters, Transferred Free of Charge

Dimitar Stoyanov signed with his Belgian and Dutch counterparts, Theo Francken and Dilan Yeşilgöz-Zegerius, on the margins of the NATO heads-of-state meeting in Ankara. The memorandum covers three Dutch Alkmaar-class minehunters and four Belgian Flower-class minehunters — both navies' national variants of the tri-national Tripartite-class hull built jointly by Belgium, the Netherlands and France from the 1980s. The vessels transfer at no cost, the two donor navies having judged them surplus.

They are surplus because both fleets are re-equipping. Belgium and the Netherlands are jointly taking delivery of twelve new mine-countermeasures vessels — six each — under their replacement mine-countermeasures, or rMCM, programme, a new class of motherships operating unmanned underwater and surface systems, built in France. Retiring the Cold War-era Tripartites frees hulls for a Black Sea navy that has struggled to modernise. Bulgaria already operates two Dutch minehunters acquired in 2021; the seven Ankara vessels roughly quadruple that inherited force at a stroke.

The timing places the signature inside a busy Bulgarian naval fortnight. The thirtieth edition of the Bulgarian-hosted Breeze exercise opened on 10 July with ten navies — Bulgaria, Albania, Georgia, Greece, Italy, Poland, Romania, Türkiye, France and the United States — running in Bulgarian territorial waters to 19 July. Mine warfare sits high on the Black Sea agenda after drifting ordnance from the war in Ukraine closed shipping lanes and prompted a standing Romanian-Turkish-Bulgarian clearance task group.

The proprietary read. The Montreux Convention caps how much non-littoral tonnage NATO can pass through the Bosphorus and for how long, so a Black Sea member cannot count on being reinforced by allied hulls in a crisis — it has to own the capability outright. Sofia's answer is second-hand: a mine force assembled from the boats two Western navies are discarding as they automate. As covered in Großwald Signal No. 101, the transfer converts a European fleet-modernisation surplus into a frontline capability for the alliance's most exposed maritime flank — cheaply, and without adding a single new hull to the water.
