Northrop Grumman High Energy Propellant Test Stand (HEPTS)

The HEPTS complex is a versatile test area that is available for component development testing of rocket engines, thrusters, gas generators, lasers and other combustion devices. Built in the mid 1960’s, the HEPTS complex is an active test area that has been upgraded and modified many times over the four decades since its construction. The facility has the capability to deliver high flow propellants at high pressures. HEPTS is equipped to supply a wide range of exotic reactants in gaseous, liquid and gel forms.

The HEPTS facility is divided into two areas with the HEPTS Control Center (HCC) positioned in the middle. The “A-side” is primarily used for rocket and propulsion testing while the “B-side” is used for testing both rockets and lasers. The facility has nine test cells capable of accommodating multiple programs and activities simultaneously.
