Norwegian fishermen accidentally catch US nuclear submarine in net

[Submariner]

10. They have done that already

When a submarine leaves New London, CT for the 100-fathom curve before diving the boat, the Russian trawlers can drop fishing nets and tow them in front of an approaching submarine hoping to snag them.

This happened frequently in the '60s to our diesel-electric boats that had two propellers and could quickly and efficiently dodge the Russkie trawlers.

I believe our very expensive nuclear submarines are, or were, escorted by a U.S. Navy tugboat to waters deep enough to dive, and protected from Soviet ship activity.
