The M900 / A954 Adrien de Gerlache was the first Algerine-class minesweeper transferred to Belgium (1949), having served in the Royal Navy as HMS Liberty (J391/M391). She was named after Baron Adrien de Gerlache de Gomery, the Belgian Antarctic explorer who led the famous 1897–1899 Belgica expedition.

Commissioned into the Belgian Navy in late 1949, she served extensively in mine clearance, North Sea patrols, NATO exercises, and ceremonial duties. In 1959 she was reclassified as an auxiliary (A954) and continued service until 1970, making her the longest-serving Belgian Algerine.

Place in War Thunder

In-game, Adrien de Gerlache would represent the “first Algerine” of Belgium, predating the Congo-deployed N’Zadi and the patrol-oriented Van Haverbeke.

  • Similar performance to M902 Van Haverbeke, but with heavier depth charge stowage instead of Squid/Hedgehog.
  • Fills the role of a Rank II/III coastal minesweeper escort (BR ~3.0).
  • Could appear as:
    – Tech tree: early Belgian Algerine.
    – Premium/event: as Belgium’s first postwar minesweeper.

With her long service and symbolic name, she would make an excellent “flagship” addition to a BeNeLux coastal lineup.
