Aus: The Sound of silence - why German lost it subs bid (verschiedne Zugriffmöglichkeiten)
...The successful French bidder, DCNS, worked hard behind the scenes last year to cast doubt in the minds of Australian officials about the noise level of the TKMS submarine.....
..DCNS modelled its estimate of the noise projection of the proposed German boat using the noise signature of its own, smaller, Scorpene-class submarine. It then compared this estimate with the noise signature for the quieter new French Barracuda submarines upon which the French-Australian submarine will be substantially based.....
...The French also loudly touted their revolutionary pump jet propulsion system, which will replace propellers on the Australian boat, the Shortfin Barracuda.Paris claimed this would give its submarine a higher tactical silent speed than the German Type 216 submarine and Japan’s evolved Soryu-class submarine, both of which would have propellers. Australian officials were said to have been highly impressed by the fact that when the Barracuda submarine accelerated, the French design was significantly quieter than either the German or the Japanese alternatives...
..They said they had reservations about the safety of the proposed lithium ion batteries that were to be installed on both the German and the Japanese submarines. Both those nations maintain that lithium ion batteries, which are four times more efficient than traditional lead acid batteries, are safe, despite small fires that have occurred in those batteries in hobby equipment, cars and airlines...
..The Australians also expressed scepticism about the ability of TKMS to upscale the size of both its Siemens motors and its submarine hulls to build a 4000-plus tonne submarine — almost double the size of previous submarines built by the company....
Der U-Boot Bau ist Schlüsseltechnologie . Die Bundesmarine hat aber kein 216er Referenzboot.
Auch die Niederländer suchen etwas größeres als die 212er. Es soll Unter- und Überwasserdrohnen starten können.
Deshalb auch wohl die Erleichterung bei Norwegen:
...geht es beim norwegischen Auftrag um Boote einer Größenordnung, mit der die Kieler Werft Erfahrung habe.....
