Die auf einem ins Wasser bis auf 100 m Tiefe absenkbaren Gestell zu befestigenden Flugkoerper wurden unterhalb der Wasseroberflaeche des Toplitzsees ausgeloest und trafen kurz nach Austritt aus dem Wasser gegen eine der nahe gelegenen Felswaende. Die Arbeiten wurden von Dr Ernst Steinhoff mit betreut, nachdem er im Jahre 1943 zum Abteilungsleiter fuer Bord-, Steuer-, und Funkmessgeraete in Peenemuende aufgestiegen war. Die Entwicklung erhielt bei der CPVA intern die Bezeichnung "Ursel". Diese Einrichtung befasste sich in ihrer Aussenstelle am Toplitzsee bei Bad Aussee im Salzburger Land (Oesterreich) ab Sommer 1944 mit der Konzeption von Unterwasserraketen. Die grundlegenden Arbeiten wurden der CPVA uebertragen.
Die Reichweite sollte dazu moeglichst ueber 3000m liegen und die Waffe beisepielsweise bei einem Zerstoerer fuer einen Leck von fuenf m2 sorgen, das diesen zum sofortigen Abbruch der U-booyjagd zwingen wuerde. Ausser der Verwendung der von aus Torpedorohren gegen Geleitfregatten und -zerstoerer zu verschiessenden schweren Werfergranaten, arbeit man an "Geraeten mit Raketenantrieb", die vom U-boot gestartet werden konnten und fuer den wirksamen Beschuss von Schiffszielen in Frage kaemen. "Nachdem der U-Bootkrieg durch die Einfuehrung leistungsfaehiger Radar-Geraete auf Seiten des Gegners in eine erste Krise geraten war, erinnerte man sich wieder der Verwendung von Raketen, die helfen sollten, nochmals einen Teil der operationellen Freiheit zurueckzugewinnen. Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-2511 did not suffer any casualties (we know of) until the time of her loss.Manfred Griehl: Luftwaffe Over America (Greenhill Books, London 2004) has a few notes about the "Ursel": (In recent years doubt has been cast on this version of events, however. U-2511 reached Bergen on 5 May, where a few days later Schnee met officers from HMS Norfolk, who at first refused to believe that U-2511 could have gotten so close without being detected. Schnee claimed he had a certain opportunity to torpedo the cruiser, but left the scene without revealing his presence and returned to base. U-2511 approached to within 500 m (547 yds) without any ASDIC (active sonar) contact from escorting destroyers. A few hours later U-2511 followed an HE (passive sonar) contact to the British cruiser HMS Norfolk, which was proceeding in company with other British warships. Schnee received Dönitz's cease-fire order. On 1 May U-2511 made her first enemy contact. The intended destination of the patrol was the Caribbean, where the boat was to be tested under all conditions. (Ing) Gerd Suhren, 'Teddy' Suhren's brother. Also aboard was one of the very few LIs to be awarded the Knight's Cross, Korvkpt. Adalbert Schnee (Knight's Cross with Oak Leaves), a highly successful commander of U-201, followed by two years on Dönitz's personal staff. The crew served under very experienced officers like Korvkpt. On the evening of 30 April, as Hitler committed suicide in Berlin, U-2511 set out from Bergen on her first and last patrol. After undergoing deep diving trials the boat left for Bergen on 18 April, arriving there on 21 April. A few days later she arrived at Horten U-boat base in Norway. On 16 March U-2511 left Kiel as part of a combat flotilla, the first type XXI U-boat to do so. She then returned to the shipyard for some remaining work to be finished. U-2511 left the Bay of Danzig on 30 January 1945, where she had completed working up exercises, including extensive trials of new equipment. The first type XXI boat on active service The crew evaded mines, surface ships, and Allied submarines to reach the harbours of Sässnitz/Rügen islands, where their passengers disembarked for a refugee camp. There the crew took on survivors from the wreck of the Wilhelm Gustloff, which had taken three torpedoes amidships from the Russian submarine S-13. Several hours into her journey, she surfaced near the Stolpe Banks in the Baltic off Leba. She left port on 30 January 1945 with her crew and dozens of refugees - of the tens of thousands - who had crowded into Danzig in hopes of safe passage from the Russian incursion. U-2511 had completed the usual working-up exercises in the Bay of Danzig, as well as trials of new equipment. About 20-30m underwater visibility - 69 metres depth.Depth: 220 feet (67 meters) Innes McCartney dove on this boat in 2001 (see his report). Blue marker shows final fate during Operation Deadlight.
