Friday Squid Blogging: US Naval Ship Attacked by Squid in 1978
Interesting story:
USS Stein was underway when her anti-submarine sonar gear suddenly stopped working. On returning to port and putting the ship in a drydock, engineers observed many deep scratches in the sonar dome’s rubber “NOFOUL” coating. In some areas, the coating was described as being shredded, with rips up to four feet long. Large claws were left embedded at the bottom of most of the scratches.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

@ Bruce,
This is not the first time Navy vessels have been attacked by large marine creatures.
Although they sound like “mysterious tales” wooden vessels in particular have been attacked by whales, orca, squid and similar.
The attacks have been put down to “feeding” in that “jetsam” of waste etc attracts a hierarch of creatures and “feeding frenzies” can arise. Commercial fishing vessels like trawlers get to see such things occasionally.
But “submarines” have been known to run into not just fishing nets, but “biologics” as well and some have given whales a nasty surprise such as during the Falklands War (apparently three were torpedoed).
The fact is many submarines when submerged move at very slow speeds as part of the measures to avoid detection by enemy vessels and this means that “biologics” can surround them, the crew would be aware of them in general but not specifically what has been hit.
We know that aircraft have “flown into mountains” and the results have mostly been catastrophic. But it is known that a submarine has hit a “seamount” and survived. It happened Jan 8th 2005 to the USS San Francisco,

So if a sub of this type was to hit a whale it’s reasonably certain it would survive, the whale or other large marine creature not so much.
