    The Black Hawk’s stern section is a real beast of a wreck, sitting upright and imposing at 45 metres. We love dropping onto the massive propellers, still attached and looking ready to spin, giving you a real sense of the ship’s scale. She was torpedoed in 1944, split in two, and this half went down fast, so there’s a lovely sense of an intact moment frozen in time. The hold is open for penetration, if you’re comfortable and properly trained. Inside, the gloom is often broken by torch beams picking out huge conger eels coiled amongst the twisted metal, their eyes reflecting the light. Outside, massive bib schools drift over the deck, sometimes so thick you can barely see the structure beneath. Visibility can be decent here, but it’s a deep dive in UK waters, so always go prepared for low light and a chill. Our tip: look for the elusive scorpion fish camouflaged on the hull plates. It’s a challenging dive, best suited for experienced wreck divers comfortable with depth and overhead environments.

    The SS Black Hawk was a Liberty ship, a mass-produced American cargo vessel vital to the Allied war effort in WWII. Built in 1943, her career was cut short on December 29th, 1944, while on passage from Cherbourg. She was struck by a torpedo from the German submarine U-772, a direct hit that broke the ship's back. The vessel split in two, and the aft (stern) section sank almost immediately, taking the engine room and rear cargo holds with it.

    Today, the stern section of the Black Hawk rests upright on the seabed at a depth of 45 metres. This is a challenging dive reserved for experienced technical or deep-air divers. The reward is a dramatic and imposing wreck, largely intact despite the violent nature of its sinking. Divers can explore the superstructure, peer into the cavernous engine room, and see the deck gun still pointing skyward. The depth has helped preserve the wreck, making it one of the most impressive deep dives in the region, a poignant memorial to the Battle of the Atlantic.
