Maunsell Forts

File:Redsandsforts.jpghttp://dprbcn.files.wordpress.com/2010/04/seafort.gifThe Maunsell Forts were small fortified towers built in the Thames and Mersey estuaries during the Second World War to help defend the United Kingdom. They were named after their designer, Guy Maunsell. The forts were decommissioned in the late 1950s and later used for other activities. One became the Principality of Sealand; boats visit the remaining forts occasionally, and a consortium called Project Redsands is planning to conserve the fort situated at Redsand. …

The design was a concrete construction; a pontoon barge on which stood two cylindrical towers on top of which was the gun platform mounting two 3.75-inch guns and two 40 mm Bofors guns. They were laid down in dry dock and assembled as complete units. They were then fitted out — the crews going on board at the same time for familiarization — before being towed out and sunk onto their sand bank positions in 1942.

The naval fort design was the latest of several that Maunsell had devised in response to Admiralty inquiries. Early ideas had considered forts in the English Channel able to take on enemy vessels. …

Maunsell also designed forts for anti-aircraft defence. These were larger installations comprising seven interconnected steel platforms, five carried guns arranged in a semicircle around the control centre and accommodation while the seventh, set further out than the gun towers, was the searchlight tower.

Three forts were placed in the Mersey and three in the Thames estuary …

In August and September 2005, artist Stephen Turner spent six weeks living alone in the searchlight tower of the Shivering Sands Fort in what he described as “an artistic exploration of isolation, investigating how one’s experience of time changes in isolation, and what creative contemplation means in a 21st-century context”.[1]

Pirate radio stations

Various forts were re-occupied for pirate radio in the mid-1960s.

In 1964, a few months after Radio Caroline went on air, Screaming Lord Sutch set up Radio Sutch in one of the towers at Shivering Sands. Sutch soon became bored with the project and sold the station to his manager Reginald Calvert who renamed the station Radio City and expanded operations into all of the five towers that remained connected. Calvert’s killing in a dispute over the station’s ownership (found to be self-defence rather than murder) contributed to the Government passing legislation against the pirates in 1967.

During the pirate era the Port of London Authority frequently complained that its monitoring radio link was being disrupted by the nearby Radio City transmitter.

Red Sands was likewise occupied by Radio Invicta, which was renamed KING Radio and then Radio 390, after its wavelength of approximately 390 metres. The 1965 Danger Man episode “Not-so-Jolly Roger” was partly filmed at Redsands and includes an acknowledgement to Radio 390 in its closing credits. Also filmed at the Red Sand forts was the 1968 Doctor Who serial Fury from the Deep, in which the complex stood in for a North Seagas refinery besieged by an intelligent seaweed creature.

The size of the Army forts made them ideal antenna platforms, since a large antenna could be based on the central tower and guyed from the surrounding towers.

A small group of radio enthusiasts set up Radio Tower on Sunk Head Naval fort, but the station was run on a shoestring, had very poor coverage and lasted only a few months. Claims by the company that they also intended to run a television service were never credible. …
