"THE PLAYERS AND THEIR MARKETS
See my earlier article of October 31, 2014 which describes how different a conventional Barracuda-SMX Ocean would be from the nuclear version (that is still under construction).
Still it has to be said that while conventional Barracuda-SMX Ocean is at the conceptual stage, the likely German bid, the TKMS-HDW 216, is even more conceptual. The increasingly used term "vapour-ware" applies to the 216.
The Australian Government may be ensuring decades of problems if it assumes that the Soryu challenge can only be met by very large submarines that don't exist. Instead a large version of the existing Scorpene or of the HDW Dolphin should be seriously considered as contenders. The automatic assumption held by the Government since 2009 that the future submarine MUST be heavier (surfaced) than the Collins forgets that the relationship between size and range is not linear. The range of the already built HDW 214 is already 12,000 miles. See more argument here.
