No. 20 Group ROC Headquarters was built in 1961 and was part of a nationwide network of monitoring stations as a result of the Cold War. The bunker was maintained in a high state of readiness until stand-down in 1991. It wasn't a shelter to ride out the end of the world; it was for early warning and monitoring, and could accommodate a staff of 60 and be self-sufficient for only 30 days. The Plant Room contains the diesel generator and air conditioning system.
The most modern room in the facility. I can't remember the name of the system, but apparently it's legitimately exciting if you're a phone engineer.

In the event that the sealed air within the bunker ran too short of oxygen, a large "gulp" of air could be drawn in through the filters to remove radioactive dust and provide fresh air to the staff. It's basically a giant Brtia filter.

However it was not large enough to allow all 60 to work simultaneously, so they would have been divided into three crews rotating between active duty, downtime, and sleep.
At the V&A they're showing Cold War Design. I know most of this stuff -- hell, based in Berlin, I live it! -- but it's nice to see it all laid out in one place.
Gedser Odde was closed to the public from 1941-89; the original building on the site, dating from the Cold War and threatened by erosion, was pulled down in 2010 and replaced by a new formidlingshus
Siren location is next to a substation and a telegraph pole which would of been linked to a normal working telephone line to send the activation command to the siren.

Photo taken at Minuteman National Historical Park in South Dakota, USA. These complexes were once part of the nuclear launch facilities dedicated to delivering nuclear missiles in the event of the Civil War. The last treaty with the Soviet Union mandated that each country keep one site "as is" and have it open to the public as a museum.
The launch facility requires advanced reservations to journey into the silos with a park ranger, who explain the daily life of nuclear launch staff and other tales from the days of Mutually Assured Destruction.
The Rotor programme was developed to advance the wartime radar technology in detecting and locating fast-flying jets. It was approved by the Air Council in June 1950. The first stage of the programme, Rotor 1, was to technically restore existing Chain Home, centrimetric early warning, Chain Home Extra Low and Ground Controlled Interception Stations and put them under the control of RAF Fighter Command. There were three main components to the Rotor Stations: the technical site, including the radars, operation blocks and other installations; the domestic site, where personnel were accommodated; and the stand-by set house, a reserve power supply. The technical site for RAF Neatishead Rotor Station was located at TG 346 184. Crew were accommodated at RAF Coltishall and the stand-by set house was located at TG 342 200.
The two main constructions at Rotor stations were the operations block and guardhouse. Operations blocks were the largest structures built at Rotor stations. They were constructed of reinforced concrete and designed to withstand 2,000lb bombs. The outer walls and roof of the Rotor operations blocks were 9ft 10in thick and the internal walls between 5.9in to 1ft 11in metres wide. The exterior was coated with an asphalt damp course and surrounded by a 5.9in brick wall. The roof was usually flush with the ground surface and up to 14 ft 2in of earth was mounded on top. The operations blocks, identified by a 'R' prefix, contained technical equipment, domestic facilities, workshops and a plant for air conditioning and gas filtration, all within a single complex.
Four of the blocks (R1-R4) were underground constructions designed for the more vulnerable sites on the east and south-east coasts. Others were semi-submerged (R6) or above ground (R5, R7-R11) heavily protected structures built to withstand 1,000lb bombs. The guardhouses were designed to resemble ''bungalows''. They were single-storey buildings capped with a flat, concrete roof, above which a pitched roof contained water tanks. They were generally constructed of brick, but were built to blend in with the local architectural style. The guard rooms also contained an armoury, store, rest room and lavatories. Those associated with underground operations blocks featured a projecting rear annex that housed a stairwell leading down to an access tunnel.
Aerial photography from 1965 shows the R3 operations bunker at the site, as well as a Type 13, a Type 7 and four Type 14 radar plinths. A range of ancillary buildings survive. The area is part of an active base and museum. In March 1947 the station was established as a Sector Operations Centre. Between 1961 to 1963 the station was reduced to care and maintenance and was then reopened as a Master Radar Station. A fire in 1966 destroyed the underground operations complex and the station was closed until 1974 with a new data-handling system occupying the original Happidrome. In 1994 the Air Defence Radar Museum opened at the site, which also continues to serve as an operational base.
Personal experience of working at Neatishead communicated by email states ''I was posted there as a sgt in 1973 and it was fully operational, T85, T84, HF200 and more all working. Furthermore, the other half of my Locking entry was posted there in 1971 and all worked on the operational radars, txs and rxs. I left in 1976 and visited again in 1977. T85, stuff of legends, 60Mw with all 12 Txs running''. Detailed history of the 50 years of the founding of RAF Neatishead 1941-1991. R30 operations room, R12 Radar equipment building and R3 underground operations block; Listed. For the designation records of this site please see The National Heritage List for England. Decommissioned 2006 and sold. Feb 2013, 25 acres of the site were again sold. The Air Defence Radar Museum was not part of the sale.
