rocket motors which has contributed to significant UK defence systems and the space programme." Present day The site, which extends to 650 acres, is now the location of Westcott Venture Park, a business park for light industry. Being the largest business park in Buckinghamshire, it is currently the registered address for 37 companies. The business park is still home to a division of the Norwegian company Nammo, which continues the design and manufacture of the LEROS rocket engines. Reaction Engines Limited began construction on a rocket test facility in 2017 to develop their SABRE rocket engine with the goal to have the new building ready for use in 2020. In 2016, the UK Government announced plans to invest £4.12 million to develop a National Propulsion Test Facility at the site, allowing cost-effective testing and development of propulsion engines. The plan involves building a new vacuum facility which will allow the simulation of high altitude testing of thrusters up to 2 kN, upgrade an existing testing chamber and open a smaller 1N thruster test chamber for the community to use. The European Space Agency will advise and oversee the initial design phase. Westcott Venture Park has also unveiled plans for a new solar photovoltaic power station in 2018 with a planned capacity of more than 15 megawatts (MW) and will cover 76 acres. This will make the business park carbon-negative since the park will generate more power than the business will use in a year.
