Remember a few years back, when they were set to lead the world in "green energy" and our politicians - especially on the west coast - were all about how we need to be more like them? Good times, good times...right up until Spain realized they were spending themselves into oblivion with unsustainable "green tech". So, much to the dismay of Iberdola and Vestas and any number of solar companies, they pulled the plug on subsidies for all that stuff. Since doing so, they've saved some serious cash. Naturally, they had to find something to do with it.
So they set aside some $3 billion to build four of the "most advanced" submarines in the world. But, having "invested" some $700 million at this point, a slight flaw has been detected in their cunning plan: they can't swim. They're just heavy enough that they'll sink like rocks. So much for the first submarines entirely designed and produced by Spain. It's looking as though they'll need to hire the USA's General Dynamics to fix the problems.
