USS GLENNON - Cornwall & Devon

The USS Glennon, an American destroyer, found its final resting place off the Normandy coast during the D-Day landings in 1944. She’s shallow, sitting at a maximum depth of just 5 metres, making her a perfect choice for extended bottom times and even snorkelers if the conditions are right. We love the Glennon for its accessibility, but don't mistake shallow for uninteresting. Her remains are scattered, showing the violence of her sinking, with plates peeled back like tin cans. You'll find sections of her hull and machinery spread across the seabed, now home to a surprising amount of life. Look for crabs scuttling amongst the twisted metal and various schooling fish flitting through the skeletal remains. Visibility can vary, as with most UK coastal sites, but on a good day, the light plays beautifully through the water, illuminating the wreck’s stark features. We’d suggest timing your dive with a slack tide for the easiest exploration. She's a poignant reminder of history, right beneath the surface.
