Yostar revealed more new Azur Lane content at the English 4th Anniversary stream it held in August 2022. It announced a new event titled “Operation Convergence” that will add three shipgirls. One of the new characters joining the ever-growing Azur Lane roster will take inspiration from KMS Blücher, the second ship of the Admiral Hipper-class of heavy cruisers. The inclusion of KMS Blücher will complete the Admiral Hipper-class roster in Azur Lane. Besides Admiral Hipper and Prinz Eugen, the game has also included the other two ships that were historically never completed as German cruisers. The fourth ship Seydlitz became the projected converted carrier named Weser. The final ship Lützow appeared as a Northern Parliament shipgirl named Tallinn, as inspired by her historical transfer to the Soviet Union. The new event will also feature the debut of KMS Z16, based on the destroyer named after Friedrich Eckholdt. In history, the ship met her end at the Battle of the Barents Sea after her crew mistook the British cruiser, HMS Sheffield, for Admiral Hipper. A fictional battlecruiser named KMS Brünhilde will complete the event’s roster.
