History

"These guns were used to arm Germany's first "Dreadnought" type battleships and battlecruisers. The battlecruiser Von der Tann used these weapons to sink HMS Indefatigable at the Battle of Jutland (Skagerrak).

During World War II these guns were used only as coastal artillery. They were then supplied with a lighter shell with a larger propellant charge for increased range.

Constructed of A tube, two layers of hoops and a jacket. Used the Krupp horizontal sliding wedge breech block.

All German 28 cm guns had an actual bore diameter of 28.3 cm (11.1")." [1]
