Replacement in general

Al the ranges of the halftrack family were to be replaced. That was a constant process. The HK-600 range was to replace all existing light and medium halftracks. HK means Halbkette, Halftrack, HKp means HalbKette gePanzert, armored halftrack. Development starts in 1939 and ends in 1942. Apart from the 603 that stands more or less on its own and is a direct descendant of the 251 all others seem to be "developers-dreams". The best there is to built; fully new designs. With the magnificent Panzer Tracts No.15-4 of Hilary Doyle, Lukas Friedli and Thomas L. Jentz that was published in 2016 a mayor leap in info was gained. (A must have!) It also covers the tracked "Katchen" project. The info is so much more that its not worth updating this page.
