Project name: Space rocket testbed
Square footage: Six-acre development
Site plan: Download Site Plan
Project completion date: December 2018
Building specifications: New manufacturing and assembly building with air conditioned offices, laboratories and control room.

The new space-age development is situated on the former ‘solid rocket motor testing’ area of the Park known as the Westcott Western Development Area. This area was granted Enterprise Zone status to attract further space propulsion and environmental engineering businesses to the site.


Reaction Engines which is based in Culham, Oxfordshire will use the new facility to test and develop a new class of innovative hypersonic and space-access propulsion system – the Synergetic Air-Breathing Rocket Engine (SABRE).


Rockspring Hanover Property Unit Trust invest heavily in sustainable growth and future prosperity of the Park. This project involved recycling demolished old bunkers and roadways which were crushed to form the bund surrounding the Reaction Engines facility.

Our new test facility and assembly building represents an important landmark for Reaction Engines as we transition from a research phase into the development and testing of the SABRE Engine. Westcott provides us with an excellent venue for our test facility, close to our headquarters and at the centre of an emerging space technology cluster. The provision of an assembly building on the site will enhance our ability to test different configurations and components meaning that we can swiftly move forward with the development of the SABRE engine.
