8.8-cm PaK 431

Krupp modified the FlaK 37 to be a anti-tank weapon.1

Design

It was designed to be mounted on a cruciform (kreuzlafette) carriage with pneumatic wheels, however, rubber supplies declined and the wheels became solid.1

Usage

By lowering jacks that bore the weight of the carriage, removing the wheels, and spreading the outrigger arms it was ready to fire.1

The gun was designed so that it could be fired with the wheels still mounted.1

The gun had safety switches that would not allow the gun to fire if it was set in a position that would allow the breech to strike the platform legs on recoil.1
