This new volume covers development from the VK 45.02(P), VK 45.03(H) to the modifications under design for the Tiger II at the end of the war. All of this illustrated with scale drawings by Hilary L. Doyle combined with drawings, sketches, and photographs depicting external modifications is well as internal views. Over twenty years of intensive research went into finding the original documents needed to create this new history on the development, characteristics, and tactical capabilities of the Tiger series. Tom Jentz has conducted an exhaustive search for suviving records of the design/assembly firms (including Henschel, Krupp, Nibelungenwerk, Porsche, and Wegmann), the Heeres-Waffenamt, the D656 series of manuals on the Tiger, and the war diaries and operations reports from the German units. The written records were supplemented by examining thousands of photos. On-sight research into almost all the surviving Tigers provided details that could only be obtained from actual specimens.New information was found on the evolution of the heavy tank series, the key decisons on the design of the Tigers, the significant modifications made during the production runs, production statistics, the Tigers characteristics and tactical capabilities, an exact accounting of the issue of the Tigers to the combat units, and combat account written directly after the actions. Tom Jentz is also the author of Germany's Tiger Tanks: Tiger I & II - Combat Tactics; Germany's Panther Tank: The Quest for Combat Supremacy; Panzertruppen 1933-1942; and Panzertruppen 1943-1945 (all four titles are available from Schiffer Publishing Ltd.).
