Popis
English: The Royal Navy during the Second World War

Sea forts in the Thames Estuary: The fort in position and ready for action. Air is still seen escaping from the sea cocks as further consolidating water ballast enters the pontoon base. One of the forts was actually in action half an hour after being put into position. These secret forts of the Thames Estuary were an effective defence against attacks by sea and air on the estuary.

Visible on the very top of the fort is a Searchlight Control radar, a medium-accuracy system used to help aim a searchlight which would then be used to illuminate the target for conventional optical aiming. The large guns on either side of the fort are 3.7-inch AA. Just left of center, at the "back" of the fort from this position, is a Bofors 40mm gun. The barrel of a second Bofors can be made out just right of center.

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.


Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
