WWI By May 1915, it was already producing proof shot for naval guns and 18 pound shells. A new erecting shop for 6-inch shells was built. This shop was fitted with the latest equipment to reduce handling to a minimum, including bench conveyors which kept the shells at the same level as the lathes from start to finish and therefore made it possible to employ a greater number of women in the shop.
Acquired as a going concern by the Ministry of Munitions for the duration of the war as the Uskside National Works; the works were managed by a Board of Management composed of the former directors of the company plus a nominee from the Ministry of Munitions.
In addition to proof shot, 18 pound and 6-inch shells, the works also manufactured pedestals for naval guns, gun carriage forgings, breach pieces for trench mortars and ships’ forgings such as shaftings and rudder mechanisms, making it something of a general purpose factory.
During the war it also continued to undertake urgent repair work for collieries.
Final production figures for the Uskside National Works include the manufacture of 24,500 18 pund shells, 16,100 4.5-inch shells and 119,700 6-inch shells.
1920 The works reverted to the control of Uskside Engineering on 31st March.
1920 Issued catalogue on electric haulage gear and details of forging in iron and steel.
