Kapitän zur See Oskar Schomberg was a Kriegsmarine officer who commanded the Wurrfler,, the submarine which was used by Oberst Herman Dietrich to intercept the Bantu Wind, allowing the Germans to obtain the Ark of the Covenant. Thereafter, the u-boat traveled to Geheimhaven, a secret Nazi stronghold on an island near Crete. Schomberg was present on the conning tower when Belloq persuaded Dietrich to open the Ark at the island rather than waiting until they were back in Berlin. The fate of him and his crew following this is unknown.
- Most of his scenes were cut, although he appears briefly on the submarine conning tower inside Geheimhaven.
- He is named for the U-Boat commander of the same name.
