Maschinenbau Kiel Weapon Systems

Maschinenbau Kiel, usually shortened to MaK, was a Kiel-based German industrial builder whose tracked-vehicle branch produced the Marder family while its marine-engine business later continued under Caterpillar.

Maschinenbau Kiel was founded in Kiel in 1948, but its industrial roots in the city reach back much further. The company moved through postwar ownership changes, entered the Krupp group, and eventually split its defense and marine businesses into separate successor lines.

This archive page keeps the historical MaK name in one place so catalog entries can point back to the builder behind Marder and other Kiel-built systems without turning the page into a generic corporate history.
