Fort Knock John

The Maunsell Naval Sea Forts were designed to provide anti-aircraft defence in the Thames estuary after the Luftwaffe began their raids on London in 1940. The Thames estuary was not as heavily defended as Dover and the south coast and therefore presented a much easier approach to London for German bombing raids.

Fort Knock John, the last of the four Naval Sea Forts, was constructed at a disused cement works on the south bank of the Thames between Northfleet and Gravesend on the Kent Coast. Access to the Thames was therefore immediately available. The forts were constructed in dry dock then floated out to their designated site in the Thames Estuary and grounded.
