Rasch began his naval service in April 1934. He entered the U-boat force in April of 1940, reporting to U-106 in September of that year. After attending a commander school, he assumed command of U-106 in October 1941. U-106 went on six patrols in the Atlantic and the Gulf of Mexico from October 1941 until his departure in April of 1943, accounting for 12 ships sunk, and another two damaged. Following U-106, Rasch served as an Admiral Staff Officer with the Oberkommando der Kriegsmarine (Naval High Command). He then served as commander of Kommando der Kleinkampfverbände (Midget Combat Units Command), overseeing operations with Seehund- and Biber-class midget u-boats, from October 1944 until the end of the war.
After the war, Rasch spent a year in Allied captivity. He then left the navy and worked as a journalist; most notably, as editor-in-chief of der Mittag, a Düsseldorf-based midday newspaper.
Hermann Rasch died in Hamburg, West Germany on 10 June 1974, aged 59.
