Hudswell, Clarke and Co
Hudswell, Clarke and Co (HCCL) was an engineering and locomotive building company based at the Railway Foundry, Leeds and founded in 1860.
The locomotive part of the business is now part of the Hunslet Engine Company. Locomotive-building was always only one part of a diverse product inventory that included underground diesel-powered mining locomotives, hydraulic pit-props and related mining equipment.
During WW2 the company diversified into armaments, as did so many other engineering companies. In the post-war period Hudswell, Clarke and Co Ltd (its full title, and note the comma) was closely involved in many secret programmes, including the British nuclear weapon programme. The airframe for the first British nuclear bomb, Blue Danube was manufactured by Hudswell Clarke at its Roundhay Road, Leeds. The airframe for Red Beard, the second generation tactical nuclear bomb, followed with that for Violet Club, the Interim Megaton Weapon; and there were many other projects.
All the bombs detonated at the Christmas Island H-bomb tests were contained in airframes designed and built by Hudswell Clarke. The company were also major contributors to other military projects, eg. the Centurion main battle tank conversion into an armoured bridgelayer, that served with the British Army for many years.
The contraction of defence manufacturing in the mid-1960s contributed to the sale and demise of the company.
