TR Thompson is a deep Sussex wreck with a stern gun.
TR Thompson is a deep Sussex wreck dive off Newhaven, a 1918 armed cargo steamer with a clear hull, a bad break amidships and a stern gun. The wreck is big enough to reward a planned tour, but it stays an advanced Channel dive because depth, visibility and boat positioning all matter. Expect a compact wreck profile, fish around the structure and a dive that works best when the sea is settled and the charter plan is tight.

Safety Notes
Keep a compact profile on the wreck, watch the break amidships and the stern gun area, and plan the dive with the boat because Channel visibility and current can load the task. Treat the enclosed sections as overhead space unless you are trained for that style of dive.
Access Restrictions
Boat access only from Sussex wreck charters; there is no shore approach.
Legal Notes
Historic wreck. Do not remove artifacts or disturb the site.
Community notes to help plan your visit.
Scuba Diving
Boat-only wreck charter from the Sussex coast, with the stern gun and the midships break as the main landmarks for a compact tour.
Freediving
Not a practical freedive target; the depth and Channel conditions make this a scuba-only wreck.
Snorkeling
Not a snorkel target; the interesting structure is well below the surface.
