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


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 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.
