The Panzerwurfmine (abbreviated to PWM) was a shaped charge hand-thrown anti-tank grenade used by Luftwaffe ground troops in World War II.
The Panzerwurfmine's appearance owed much to the Panzerfaust (specifically its warhead), which was of similar construction and operation.
The Panzerwurfmine is designed to achieve the stable flight needed by the deployment of large fins or canvas lengths at the back of the design, to stabilise the trajectory of the grenade and therefore make a ninety degree angle contact more likely.
It was discontinued in favour of the Panzerwurfmine Kurz ("short"), which was stabilised by a canvas strip that rolled out when the device was thrown, and was also shorter.
Both designs had warheads with a diameter of 11.4cm, carrying a shaped charge of 500g that could penetrate approximately 150mm of RHA at zero degrees.
