Input: Question: In what country was the keel for the Wacht laid down? Passage:The keel for Wacht was laid down in August 1886 at the AG Weser shipyard in Bremen. She was launched on 27 August 1887 and Vizeadmiral (Vice Admiral) Alexander von Monts, the chief of the Marinestation der Nordsee (North Sea Naval Station) christened the ship. In early 1888, she was transferred to Wilhelmshaven, where her armament was installed, and she was commissioned on 9 August to begin sea trials. These concluded on 13 December in Wilhelmshaven. She was temporarily assigned to the newly-created Reserve Division of the North Sea over the winter of 18881889 before being transferred to Kiel on 1 May to begin engine trials, after which she was assigned to the Maneuver Squadron. During training exercises with the squadron, Wacht suffered a burst boiler tube on 20 June that forced her to return to port for repairs. In early August, she joined the squadron for a visit to Britain, arriving back in Wilhelmshaven on 31 August. The fleet then conducted its annual large-scale maneuvers. After the maneuvers ended in September, Korvettenkapitan (KKCorvette Captain) Friedrich von Baudissin took command of the vessel.
