Description

A series of weapons with similar performance that were used as anti-torpedo boat guns on pre-dreadnoughts, main guns on torpedo boats and destroyers and later developed into Germany's first AAA gun. The Flak L/45 was also used to replace some of the 8.8 cm/35 anti-torpedo boat guns on older warships.

During the 1920s these guns were used as an interim measure on the Panzerschiffe Deutschland and on light cruisers until the new 8.8 cm/76 SK C/32 gun was available, with most ships being refitted by 1939.

During the 1930s surviving guns were modified to take the same ammunition as was used in the 8.8 cm/45 (3.4") SK C/30 and then had the same performance as did that gun.

  1. ^Quantities and types shown above are "as built." Many ships had 8.8 cm/45 anti-ship guns removed during World War I in order to fit 8.8 cm/45 FLAK guns. Similarly, many older torpedoboats traded their 8.8 cm/30 and 8.8 cm/35 guns for the more powerful 8.8 cm/45 guns. Likewise, some torpedo boats were rearmed with the even more powerful 10.5 cm/45 Tbts guns.
