ROF Bridgwater
From Wikipedia, the free encyclopedia
Royal Ordnance Factory (ROF) Bridgwater is a factory which produced high explosives for munitions.
It is situated between the villages of Puriton and Woolavington in the Sedgemoor district of Somerset, UK; but was always known as ROF Bridgwater, after the nearest town. It is located slightly above sea level, all of it lying between the 5 and 10 metre contours. BAE Systems plan to close the facility in 2007.

[edit] History
It was constructed early in World War II for the Ministry of Supply, with the Ministry of Works acting as Agents. It was designed as an Explosive ROF, to produce RDX, which was then a new experimental high-explosive (Cocroft, 2000) developed at the RGPF Waltham Abbey. Construction work started in 1939 and the factory opened in 1941.
[edit] Infrastructure
As munitions production needed a guaranteed all year-round clean water supply of several million gallons per day, the site was ideally suituated, obtaining supplies from two sources via the Somerset Levels: the artificial Huntspill River which was dug during the construction of the factory and also from the King's Sedgemoor Drain, which was also widened at the same time (Williams, 1970). Both of these waterways are now an integral part of the drainage system of the Somerset Levels.
The ROF was essentially self-supporting other than for the supply of raw materials. It generated high-pressure steam for heating and production processes using its own coal-fired power station; it could also produce electricity using a steam turbine. During World War II before the National Grid was fully developed, it was connected to two independent public electricity generation stations: Portishead power station (now demolished) and Shepton Mallet power station.
Housing for workers was built, between 1940 and 1941, as "pre-fabs" in the adjacent village of Woolavington. Hostels for single workers were also built at nearby Dunball, by the King's Sedgemoor Drain.
The site was guarded until shortly after privatisation by the MoD Police. The MoD Police had their own barracks and canteen located opposite the main factory gates. These have long since been demolished. However three brick-built MoD Police houses are still in use on the Woolavington Road, but they are no longer occupied by the police.
ROF Bridgwater was connected to the Great Western Railway (GWR) by a private branch line and sidings. A new bridge was built in the early 1970s to carry this line over the M5 motorway, just north of junction 23, when the M5 was extended southwards from its terminal junction with the M50 motorway. The railway branch became disused after the privatisation of the ROFs and the rail tracks have been lifted. The British Rail sidings were known as Huntspill (Puriton) (Baker 1980).
[edit] Production
During the construction period it appears that the decision was made to fill munitions, including the bouncing bomb, with a mixture of TNT and RDX rather than RDX alone. ROF Bridgwater manufactured RDX in two separate production units which was sent to Filling Factories, such as ROF Chorley and ROF Glascoed for filling into munitions. It also concentrated and re-cycled its own sulfuric acid.
Like all ROFs at the time, ROF Bridgwater operated as a production factory. Formulation of explosives, propellants and munitions was carried out at separate government-owned research and development establishments such as the Research Department, which was initially based at the Royal Arsenal, Woolwich and then Fort Halstead; and at PERME Waltham Abbey, which later transferred to RARDE Fort Halstead. After privatisation Royal Ordnance PLC took over some of the UK government-owned research and development capablity, other parts were closed or became part of QinetiQ.
[edit] Post World War II
During the slack period between 1945 and the Korean War ROF Bridgwater, like ROF Chorley and ROF Glascoed, built two-storey pre-fabricated concrete houses (Cocroft, 2000).
Production of the new high explosive HMX was added in 1955. In the 1960s and 1970s, ROF Bridgwater started producing plastic rocket propellant formulated with ammonium perchlorate and poly-isobutylene rubber as two of its main ingredients; and Trinitrotoluene (TNT) manufacture was added in 1980.
[edit] Privatisation
ROF Bridgwater is now owned by BAE Systems after the Royal Ordnance factories were privatised on 2 January 1985 and became part of the Explosive Division of Royal Ordnance Plc, later RO Defence. Both names, Royal Ordnance and RO Defence, have been dropped and the site is now known as BAE Systems Land Systems now BAE Systems Land and Armaments. BAE Systems plan to close the facility in 2007.
