ROF Glascoed


ROF Glascoed

ROF Glascoed (now BAE Systems Land Systems Munitions Glascoed) was a UK government-owned, Royal Ordnance Factory. It was designed as one of 20 munitions filling factories. It was planned as a "Permanent" Royal Ordnance Factory with the intention that, unlike some other similar facilities, it would remain open for production after the end of World War II. After privatisation of the Royal Ordnance Factories in the 1980s it became part of Royal Ordnance PLC and later a production unit of BAE Systems.

Early history

In the late 1930s leading up to the outbreak of war in 1939, the British government developed a strategy to disperse armaments and munitions production away from major cities and the southeast part of England which were felt to be especially vulnerable to bombing from the air. As a result the Ministry of Supply built a number of Royal Ordnance Factories and satellite factories.

A munitions-filling factory was sited at Glascoed in a valley between Pontypool and Usk in Monmouthshire. The site was chosen for its seclusion and sheltered topography surrounded by hills and its damp micro-climate was suited for the handling of explosives. Mostly agricultural land was acquired by compulsory purchase. In addition, the large workforce needed would benefit a region of the UK hit by particularly heavy unemployment in the 1930s Great Depression.

The new factory was designed at The Royal Arsenal, Woolwich ("Woolwich Arsenal"), based on its long experience in munitions production. Safety considerations were paramount. The design, style and spacing of individual production buildings meant that they were separated by wide open spaces as well as approx 20 feet (3 m) high grassed embankments and extremely thick reinforced concrete walls and overbridges, called traverses. The purpose of the traverse was to deflect any explosion skyward rather than outward to any adjacent buildings or structures.

The site was built with extensive underground magazines, comprehensive lightning protection and individual buildings linked by paths, roads and railways.

Building work on the 1,000 acre (4 km²) site started in February 1938, with the Ministry of Works acting as s; and was undertaken by a construction company from Cardiff. Full production was achieved in 1941-1942.

World War II and Korean War activity

At its peak, ROF Glascoed boasted nearly 700 separate buildings, each designated for a particular process and used as required. It still has in excess of 10 miles (16 km) of roads, an 8 mile (13 km) perimeter fence and, until more recent years, its own 17 mile (27 km) standard gauge railway system. This included a dedicated passenger station and freight marshalling yards. It was linked to the Great Western Railway (GWR) branch line that ran between Pontypool Road and Monmouth. This rail link enabled the three-times daily movement of up to 13,000 workers in and out of the site as well as the receipt of raw materials and components and the despatch of finished munitions. A small housing estate was built close-by to accommodate managers and staff who had to respond quickly in emergencies.

Initially it was intended that ROF Glascoed would produce sea-mines for the Royal Navy. However as well as these, heavy bombs and pyrotechnics (such as target indicators and skymarkers) were supplied to the RAF. Among the weapons filled and assembled by ROF Glascoed were the bouncing bomb, designed by Barnes Wallis and delivered to the Ruhr area of Germany by the Dambusters, RAF 617 squadron.

Contemporary ARP planning was largely based on Stanley Baldwin's assertion that "the bomber will always get through". So, near Glascoed, the local Folly Tower on a hill top at nearby Pontypool was seen as an aiming-off point for the Luftwaffe to attack the ROF factory. The Tower was demolished at the start of the war and not rebuilt until 1994 when it became a minor tourist attraction. As it was, ROF Glascoed was bombed only twice during the war. On one occasion, a worker was killed and several injured by a lone bomber which caused minor damage. Post-war debriefing records show that the bomber's crew were convinced they had bombed Filton aerodrome in Bristol, some forty miles (65 km) away.

As demand for weapons and ammunition declined with the end of the war, many Royal Ordnance Factories were closed. ROF Glascoed was retained and supplemented its output by manufacturing concrete building products and by scrapping surplus munitions. The growing hostility of the Cold War as evidenced by the Korean War saw a much wider range of munitions assembled, filled and packed at ROF Glascoed. These included ammunition for field guns and howitzers, tanks and other fighting vehicles, mortar and aerial bombs, warheads for missiles and torpedoes, flares, pyrotechnics and smoke bombs.

Post-war survival

The Royal Ordnance Factories were part of a government department until they were privatised in 1987. Today Glascoed is a business unit of BAE Systems Land Systems (Munitions & Ordnance) Ltd. With the closure of other ROFs, Glascoed remains the only ammunition filling facility in the UK and exports its products, as well as supplying the British Ministry of Defence (MoD). Glascoed now employs about 400 people and is investing heavily in R&D and improved production facilities.

In recent years, Glascoed has developed an expertise with Insensitive Munitions [ [http://www.globalsecurity.org/military/systems/munitions/im.htm Insensitive Munitions (IM) ] ] in artillery shells and other warheads. These employ PBX compositions such as Rowanex 3601 (booster) and Rowanex 1100 (main charge) designed to minimise the risk of accidents eg inadvertent detonation by dropping, heat, friction or impact. One such accident occurred on the USS Forrestal in 1967 [ [http://www.forrestal.org/fidfacts/page13.htm USS Forrestal The Tragic Fire - July 29, 1967 ] ] .

Until the mid-1990s, in the interests of security, British Ordnance Survey maps omitted the details of all ROF sites; and showed the sites as they existed before the ROF's construction, although it was sometimes possible to identify the site boundaries. More recent editions show the detail of the buildings, internal roads, and rail links, labelled simply as "Depot" or "Works" [ [http://getamap.ordnancesurvey.co.uk/getamap/frames.htm?mapAction=gaz&gazName=g&gazString=SO3495001549 Get-a-map from Ordnance Survey ] ] .

The site is also used by Gwent Constabulary for firearms and dog training, having its own kennels and firing range.
