25mmBatterien

25mmBatterien refers to a specific type of ammunition used in certain anti-aircraft guns. The designation "25mm" indicates the caliber of the projectile, meaning the diameter of the barrel and the shell is approximately 25 millimeters. The term "Batterien" is German and translates to "batteries," implying a group or set of these guns, often deployed together for defensive purposes.

These types of guns and their ammunition were primarily developed and employed during the mid-20th century, particularly around World War II. Their purpose was to engage low-flying aircraft, such as bombers and fighter planes, that posed a threat to ground forces or important installations. The 25mm caliber offered a balance between projectile size and rate of fire, making it effective against the aircraft of that era.

The ammunition itself would typically consist of an explosive projectile designed to detonate on impact or in proximity to the target. Various types of 25mm ammunition might have existed, including high-explosive (HE), armor-piercing (AP), or tracer rounds, depending on the intended tactical application. While perhaps less common than larger caliber anti-aircraft guns, 25mm batteries played a role in air defense systems.
