The Summerfield Research Station is a development and production site for solid rocket motors in the United Kingdom officially formed on 1 September 1951 by the Ministry of Supply.
It was set up on the grounds of a former World War II munitions factory just south of Kidderminster, southwest of Birmingham.
Previous UK rocket motors, like those on the RP-3, used Cordite as their propellant, formed into a solid using various binders and then moulded into cylinders with internal cavities to control the rate of burn.
The combination of these two features formed the basis for military rockets until the introduction of aluminum-boosted propellants in the 1960s.
Today the site is officially known as Roxel (UK Rocket Motors) Limited.
