{{Main|Mine shell}}
The mine shell is a particular form of HE shell developed for use in small caliber weapons such as 20&nbsp;mm to 30&nbsp;mm cannon. Small HE shells of conventional design can contain only a limited amount of explosive. By using a thin-walled steel casing of high tensile strength, a larger explosive charge can be used. Most commonly the explosive charge also was a more expensive but higher-detonation-energy type.

The ''mine shell'' concept was invented by the Germans in the Second World War primarily for use in aircraft guns intended to be fired at opposing aircraft. Mine shells produced relatively little damage due to fragments, but a much more powerful blast. The [[aluminium]] structures and skins of Second World War [[aircraft]] were readily damaged by this greater level of blast.
