Modified from a BBC report, July 13, 2016 http://www.bbc.com/news/uk-england-cornwall-36781151:
Until its tangle with a trawl net Portuguese submarine NRP Tridente was training with the UK Royal Navy 55km off
Lizard Point,
Cornwall. Lizard Point is not shaped like the famous bitey reptile but so named because "Lysardh" in the regional Cornish language means "the high court".
Tridente, while submerged, became caught in the nets of French trawler, Daytona, the Royal Navy said July 13, 2016. The trawler Daytona is registered to Saint-Brieuc, in north west France.
"The submarine immediately surfaced and made contact
with the trawler," French maritime authorities said in a statement. There were no casualties and both vessels were safe, the
navy said."
BACKGROUND/COMMENT
The French trawler was fortunate that it encountered a conventional sub (SSK) that was then polite enough to stop and surface.
Nuclear subs have been known to tow whole trawler boats under.
In "1990, four
fishermen died when their trawler was dragged under by a British submarine
on a training exercise off the west coast of Scotland.") Sometimes suspected SSNs don't stop - maybe due to the higher secrecy level (than average SSK missions) that they operate under.
The BBC reported, that later, in 2004, five crew died when the French trawler Bugaled
Breizh sank off Lizard Point. "The families of the victims claim the trawler was dragged
underwater by a submarine involved in an international military exercise, but
courts ruled there is no supporting evidence."
The propulsion patterns of Portugal's two Tridente class subs suggest shorter range, probably defensive, missions such as monitoring the approaches to the Strait of Gibraltar from both the Atlantic and Mediterranean sides.
With a good microscope you can see the submarines of the Marinha de Guerra Portuguesa berthed at Lisbon Naval Base (above) This map has been provided by my good friend and colleague Vasco .
