Title: Excellent study of military technology
Review: Although the story of the role of technology in the defeat of german U-boats in the Battle of the Atalantic has often been told, the role of HF-DF (huff-duff) has usually been slighted. This book corrects that situation. Secret Weapon is an important new contribution in out understanding of the battle of the Atlantic, and an archetype of contemporary history of military technology. (From a longer review that appeared in the New York Military Affairs Symposium Newsletter).
