"Emden" embarked on her first long-range training cruise on 14 November 1926 from Wilhelmshaven. The ship traveled to south around Africa and across the Indian Ocean, where she stopped in the Cocos Islands, where the wreck of the original "Emden" was still present. The crew held a memorial service there on 15 March 1927 before continuing on to East Asian waters. She visited ports in Japan before crossing the northern Pacific Ocean to Alaska and then steamed down the western coast of North America, calling in various harbors along the way. "Emden" continued south through Central and South American waters, crossing into the Atlantic Ocean and turning north; the ship was in Rio de Janeiro, Brazil on 25 December. She returned to Germany by way of the Azores and Vilagarcía, Spain, arriving in Wilhelmhaven on 14 March 1928.
