U-Boats in action

Stern, R.C.: 1977 USA, softcover 50 pages, with many photos, plans and detailed drawings. This publication focuses almost entirely on visual depictions and short descriptions of German submarines instead of providing a deep technical narrative. The brief overview mainly serves as a basic introduction for model builders and hobbyists who want to see rare wartime photographs and camouflage patterns rather than exhaustive combat histories.
