Embarrassment for the navy had continued, with a mine accident during rehearsals for the Baltic Fleet's celebration of Navy Day in St. Petersburg in July 2005 and the "Priz-"class mini-submarine AS-28 having to be rescued by a joint British/U.S. effort using a Royal Navy unmanned submersible in the Far East in early August 2005. However exercises and operations continued; Peace Mission 2005 in August 2005 involved a new level of cooperation between Russia and the Chinese People's Liberation Army Navy. Two months later the Slava-class cruiser "Varyag" led Russian participation in INDRA 2005, held off Visakhapatnam between 14 and 20 October 2005. It included surface firings, air defence, and anti-submarine warfare (ASW) exercises.
