The Mackensen class was the last class of battlecruisers to be built by Germany in World War I. None of them were ever completed as shipbuilding priorities were concentrated on U-boats and destroyers. They were broken up in the early 1920s.

The design of the Mackensens was a much improved version of the previous Derfflinger class. They featured a new 350 mm (13.8-inch) gun. A further three ships of the Mackensen class were originally planned. However, these three ships were later reprogrammed as larger ships, incorporating 380 mm (15-inch) main-battery guns, as a response to the Royal Navy's Renown class. These last three ships are generally known as the Ersatz Yorck class, as the first ship of the class was designed to replace the armored cruiser Yorck, which had struck German mines early in the war and sunk. However, very little construction progress was made on these ships. The three units of the Derfflinger-class battlecruisers (German:Schlachtkreuzer) of the Deutschen Kaiserliche Marine were ordered for the 1912 to 1913 Naval Building Programme of the Imperial German Navy as a reply to the Royal Navys three new Indefatigable class battlecruisers that were launched a few years earlier. ...

In response to the Mackensens, the British laid down the Admiral class battlecruisers for the Royal Navy, all but one of which would be cancelled later, the sole survivor (completed after the war) being HMS Hood. The Admiral-class battlecruisers were a group of four British Royal Navy battlecruisers designed near the end of World War I. These ships were intended to counter the German Kaiserliche Marine Mackensen-class battlecruisers that were then under construction. ... This article is about the navy of the United Kingdom. ...
