on water as a result of the damage to her aft section by the engine rooms, and sank north-east of Anholt. The shot-down Liberator crashed away, and all on board the plane were lost. U-534 had aboard a crew of 52 men; all escaped the sub, 49 survived to be rescued. Five were trapped in the torpedo room as she began to sink, but they managed to escape through the torpedo loading hatch once the boat had settled on the sea bed. They planned their escape the way that they had been trained, exiting through the forward torpedo hatch once the U-boat had settled on the seabed and swimming to the surface from a depth of . One of them, 17-year-old radio operator, Josef Neudorfer, failed to exhale as he was surfacing and died from damage to his lungs. Two others (including the submarine's radio operator of Argentine origin) died of exposure while in the water. Armament FLAK weaponry U-534 carried the rare Twin 3.7 cm Flakzwilling M43U on the DLM42 mount. This was one of the best AA weapons of Nazi Germany's Kriegsmarine. The DLM42 mount was used mainly on the Type IX as it was too heavy for the Type VII U-boats. The 3.7 cm Flak M42U was the marine version of the 3.7 cm Flak used by the Kriegsmarine on Type VII and Type IX U-boats. Anti-sonar counter-measures Just above the propeller shaft on the starboard side was the exit chute of a Pillenwerfer. It could deploy an anti-sonar decoy called Bold, named after Kobold, a goblin in German folklore. This made a false target for the enemy's sonar by creating a screen of bubbles from the chemical reaction of calcium hydride with sea water. Salvage U-534 lay on the sea bed for nearly 41 years, until she was discovered at a depth of 67 meters in 1986 by a Danish wreck hunter, Aage Jensen. Shortly afterwards, the wreck hunters' group contacted Danish media millionaire Karsten Ree, who sponsored raising the submarine, as rumours of Nazi gold caused intense media coverage. However, the boat turned out to contain nothing unusual. U-534 was raised to the surface on 23 August 1993 by the Dutch salvage company Smit Tak. Museum ship Transported to Birkenhead, England, in 1996, the vessel formed part of the Warship Preservation Trust's collection at Birkenhead Docks until the museum closed on 5 February 2006. On
