| Description |
English: The Royal Navy during the Second World War Sea forts in the Thames Estuary: The completed fort with its steel superstructure, guns and personnel is towed to sea. The four feet high wooden bulwarks around the pontoon were removed before sinking the fort. The reinforced concrete cylinder on the pontoon bow was later rolled off and suspended by wires under the bow, when the fort was grounded this cylinder was crushed and thus broke the impact on the sea bed. These secret forts of the Thames Estuary were an effective defence against attacks by sea and air on the estuary. The tugboat to the left of centre is likely the Challenge built in 1931 at Alexander Hall & Sons shipyard. The Royal Navy Harbour Defence Motor Launch ML 1008 (ordered January 1940, commissioned June 1941, repaired January 1942, dismantled August 1946) appears at the left. |

Licensing edit
This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.  |
