Record:

- Launched by the German Navy on 12 September 1909 as SMS Goeben.

- Commisioned by Turkey and renamed Yavuz on 16 August 1914 in Istanbul.

- On 28 October 1914, Yavuz led a sortie into the Black Sea and began raiding Russian assets. The next day the Crimean port of Sevastopol was bombarded. Odessa was also attacked, resulting in the Russian declaration of war on Turkey.

- On 18 November 1914, Yavuz fought a number of Russian battleships and suffered a hit from a 12-inch (305 mm) shell, killing 13 and wounding 3 crew.

- Bombarded Batumi on 10 December 1914.
- On 26 December 1914, Yavuz struck two mines at the entrance to the Bosphorus and took on about 2,000 tons of water. The damage put her out of action for a couple of months.

- During April 1915, Yavuz sank two Russian merchant ships. On 10 May 1915, in another encounter with Russian battleships, Yavuz received three 12-inch (305 mm) shell hits without inflicting any damage herself.
- On 14 November 1915, the Russian submarine Morz made an unsuccessful attack on Yavuz.
- On 7 January 1916, Yavuz fought with Russia's new dreadnaught Imperatritsa Ekaterina Velikaya in a fight which lasted only 11 minutes, with Yavuz using its superior speed to escape.

- In February 1916, Yavuz carried Turkish troops to the Caucasus front (to the port of Trabzon).

- In February and April 1916, Midilli carried Turkish troops to the Caucasus front (to the port of Trabzon). In July 1916, she attacked Russian troop transports.

- In early July 1916, during another attempt to bombard Russian ports and after shelling the harbour at Tuapse, Yavuz again encountered a superior Russian force which included Imperatritsa Ekaterina Velikaya, but due to mistakes of Russian commanders, she managed to escape. The appearance of superior Russian battleships heavily curtailed further operations of Yavuz in the Black Sea.

- On 20 January 1918, Yavuz together with Midilli emerged from the Dardanelles and encountered the British ships near the island of Imbros. They managed to outgun the British destroyers and monitors. However, they ran into a minefield; Midilli sank immediately but Yavuz, which struck three mines and was badly holed, managed to struggle back to the Dardanelles where she beached at the Narrows. The British made repeated attempts to bomb her but she survived and after being refloated on 26 January 1918, returned to Istanbul.

- Laid up at Izmit on 9 November 1918.

- Refitted by the Naval Forces of the Republic of Turkey between 1926-1930 at the shipyards in Gölcük.

- Laid up at Gölcük in 1948.

- Decommissioned on 20 December 1950.

- Sold for breaking up in 1971. Broken up between 1973 and 1976.
