Krögerwerft

Krögerwerft was a German shipyard lineage rooted in the Kröger brothers' boatbuilding business and later centered at Schacht-Audorf near Rendsburg on the Kiel Canal. Its defense relevance comes from small naval and mine-warfare vessels for the Bundesmarine and German Navy, including Frauenlob-class inshore minesweepers and three of the German Frankenthal-class minehunters, before the Rendsburg yard became part of the Lürssen group.

The Kröger yard history runs through several wartime and postwar locations, but the catalog-relevant naval work is the Rendsburg/Schacht-Audorf operation. Maritime reference records identify individual Frauenlob-class boats with Krögerwerft, Rendsburg as builder, while Forecast International's Frankenthal-class program history says the September 1988 order for ten MJ-332 minehunters was split among Lürssen, Abeking & Rasmussen, and Krögerwerft.

After Lürssen acquired the Lürssen-Kröger yard near Rendsburg in 1987, the site remained part of a larger northern-German shipbuilding network. Lürssen's current location material describes Rendsburg as a Kiel Canal facility for custom yacht construction, refit, and maintenance, while maritime yard directories continue to identify the location as the former Lürssen-Kröger shipyard with navy maintenance and yacht refit activity.

Historical sources use several spellings for the same yard lineage, including Krögerwerft, Kröger-Werft, and Lürssen-Kröger. This profile is scoped to the Rendsburg/Schacht-Audorf shipyard attribution and does not merge the separate Lürssen manufacturer labels used elsewhere in the catalog.

Bundesarchiv-linked records and specialist ship databases describe the boats as Class 362 coastal guard craft that became Class 394 inshore minesweepers, with ten Bundesmarine hulls entering service from 1966 to 1969 and three former German boats later forming part of Estonia's post-restoration mine-countermeasures force into the 2000s.

Bundeswehr data describe ten MJ332 boats with non-magnetic steel hulls, Seefuchs/SeaFox mine-disposal drones, mine rails, diver facilities, and MJ332B, MJ332C, and MJ332CL mission fits, while former German hulls also served the UAE as Al Murjan-class mine-countermeasure vessels.
