COMMENT
Dutch submarines need the range to get to the Dutch Caribbeanand the Middle East to monitor communications.
The Dutch Navy would probably prefer a largish submarine of around 2,500 tons, like the Netherland’s existing Walrus-classbut Germany may be aiming for a smaller, cheaper, offering - more in line with Netherlands’ Finance Ministry hopes.
