Klaus Hänert joined the Kriegsmarine in 1936, joining the famous Olympia Crew. After the usual training he served on destroyer Z 6 Theodor Riedel until June 1940. He served in a staff position from July to Jan 1941 and then as Watch Officer on destroyer Z 15 Erich Steinbrinck from Feb to Dec 1941 (Busch & Röll, 1999).
Hänert joined the veteran boat U-68, commanded by the ace Karl Friedrich Merten, and served as its Second Watch officer (2WO) from May to July 1942. Oblt. Hänert served on the boat during a successful 58-day patrol into the Caribbean where they sank 7 ships for over 50,000 tons. Reaching port in early July 1942 Hänert became its First Watch Officer (1WO) and went out on another patrol, this time into the South Atlantic and to Cape town area, where they sank 9 ships for over 56,000 tons (Rohwer, 1998).
Hänert joined the 2. ULD as instructor from Jan to April 1943 when he began his U-boat Commander training with the 24th Flotilla, finishing his courses in May 1943. While going through his commander training he was promoted to Kapitänleutnant on 1 Feb 1943. He then began his U-boat familiarization (Baubelehrung) to prepare him for his new boat and spent 2 months learning all there was to learn about the new IXC/40 boat being built in Hamburg (Busch & Röll, 1999).
Kptlt. Klaus Hänert commissioned the new U-550 on 28 Jul 1943 and took the boat into the Baltic where he and his crew would spend the next months training and applying the costly lessons of war (Busch & Röll, 1999).
First war patrol as Commander
On 6 Feb 1944 Kptlt. Klaus Hänert sailed from Kiel, Germany with his U-550 on his first war patrol as commander (Busch & Röll, 1997).
The boat was ordered to patrol off the US east coast. En route on 22 Feb the boat was attacked by a Canadian Catalina aircraft when the they were south of Iceland - two men were killed but the boat managed to continue on its patrol (Blair, 1998). Finally on 16 April 1944, after 71 days at sea, their luck ran out. They torpedoed the large tanker Pan Pennsylvania and thus brought attention to themselves. Shortly afterwards the boat was hunted down by American destroyer escorts and sunk after a battle where U-550 tried to fight back with its guns on the surface (Niestlé, 1998).
Kptlt. Klaus Hänert was captured, along with 11 of his men (44 died) when the boat was sunk. He spent 3 and a half years in Allied captivity, being released on 31 Dec 1947 (Busch & Röll, 1999).
