U106E

U106E is a designation that appears in some naval records and online databases as the hull number of a submarine, but no single, widely accepted profile of a vessel by that exact identifier exists in the public record. In German U-boat nomenclature, the prefix U denotes Unterseeboot (submarine). Numbers following the prefix usually identify a specific hull, while suffixes (such as ‘E’) can indicate variant batches, export versions, or postwar reassignments depending on the source. The combination 'U106E' is therefore ambiguous: different archives may apply the label to different, unrelated items or treat it as an unbuilt or renumbered designation.

Most discussions of U106E reference it only tangentially, often in the context of comparing it with U-106, a confirmed World War II submarine, or with lists that enumerate possible variants without authoritative corroboration. Because primary source material is inconsistent and may be fragmentary, historians typically treat U106E as an unclear or disputed designation rather than a conclusively identified vessel.

If you have a specific context for U106E (era, navy, or archive), providing that would help locate the precise record.
