German Schnellboote penetrated forces conducting pre-D-Day training and caused a tremendous loss of life during Exercise Tiger. The attack shows that torpedoes remained dangerous against larger, vulnerable formations even as coastal warfare shifted toward gun-boat engagements. The disaster did not drive MGB development, so it remains a brief operational example here. Exercise Tiger belongs in a full account of D-Day preparation. This distinction separates the event's operational significance from its influence on ship design.

Exercise Tiger as a Schnellboot warning
The deadly Schnellboot attack during pre-D-Day Exercise Tiger receives brief treatment here because it lies beyond the main focus of this design survey.
