An attempt to deploy a new submarine for Spain's navy has run aground again, after it emerged it cannot fit in its dock, Spanish media reports.

The S-80 boat was redesigned at great expense after an earlier mistake meant it had problems floating, and it was lengthened to correct the issue.

It estimated that the cost of each S-80 "Plus" submarine would now be close to €1bn ($1.6bn AUD)
