A new submarine commissioned by the Spanish navy at a cost of 2.2 billion euros (£1.9billion) has been discovered to contain a serious design flaw – it is too heavy and will sink like a stone.
Miscalculations at the engineering stage have been blamed for a two-year delay in delivery of the first of four submarines commissioned from Spain's state-owned shipbuilder Navantia.
Last month it emerged that the Isaac Peral sub – part of the new S-80 series and named in honor of the Spanish man credited by some as the inventor of the underwater vessel – was at least 75 tons overweight, an excess that could compromise its ability to surface after submerging.

Wait, did you carry the six when you did the multiplication?
Multiplication??!! I thought it was an addition...
Hey, ask North Korea if they want to buy a sub....
