$3 Billion Dollar Spanish Submarine Will Sink Without Design Changes

Which will cost millions more

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 honour 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.
