Emden and her sister ship went into drydock in 1934 for a life-extension refit. The changes were quite minor: the three single 88mm/45 AA weapons were replaced with two twin 88mm/72 DP mounts, the older 20mm mountings were removed and replaced with 37mm mounts, and the 500mm torpedo tubes were replaced by 533mm tubes. Mine rails were also installed. The boilers were cleaned but not replaced.
