You’re right. Technical foul to call it the St. Lawrence Seaway, but there were smaller locks along the St. Lawrence River and Welland Canal that permitted passage of smaller vessels, but not large enough for Gato Class Submarines.

“... there were smaller locks along the St. Lawrence River and Welland Canal that permitted passage of smaller vessels, but not large enough for Gato Class Submarines.”

Posters with greater knowledge of US & Allied submarine production 1939-45 must shed light on which subs were launched, and from where.

Please accept my apologies for lack of clarity: my original focus was on the threat. My intent was to remind the forum that there never has any interval of time when any oceangoing warships were able to reach any of North America’s Great Lakes, unimpeded or unobserved.

Technological advances in civil engineering and vessel power systems worked together to improve access: from roughly 1800 to 1960, impediments to access were reduced, but the chances of any hostile naval vessel gaining access unobserved improved only slightly.
