The Northrop Grumman-built Long Duration Propulsive ESPA (LDPE)-3A satellite is to support US Space Force-67 National Security mission.
Press Release, Dulles VA, 16 January 2023: Northrop Grumman Corporation’s Long Duration Propulsive ESPA (LDPE)-3A spacecraft launched successfully in support of the USSF-67 mission. This spacecraft helps advance rapid access to space for the US Space Force and marks the third successful launch in the LDPE programme.
The LDPE-3A was built using Northrop Grumman’s ESPAStar, providing rapid access to space by maximising the available volume inside a launch vehicle. This bus carries hardware for five independent missions, eliminating the need for each mission to wait for a future launch opportunity.
“From conception and development of next-generation space technology, like ESPAStar, to on-orbit command and control, we are prepared to support the full lifecycle of our customer’s missions throughout the ever-evolving threat environment,” said Troy Brashear, vice president, national security systems, Northrop Grumman.
Northrop Grumman also designed, developed and implemented the command and control, and mission execution software system for the LDPE programme. The software system uses a common baseline across multiple programmes, putting more capability in the hands of customer operators at a lower cost. The ESPAStar product employs a customised version of a standard ESPA ring, providing added propulsion, power and avionic subsystems. A SpaceX Falcon Heavy launch vehicle will deliver LDPE-3A to near-geosynchronous Earth orbit for a one-year mission life.
USSF-67 is the third mission for the LDPE programme. The Northrop Grumman-built LDPE-1 launched aboard the STP-3 mission in December 2021 and LDPE-2 aboard the USSF-44 mission in November 2022. Northrop Grumman will continue to deliver future ESPAStar spacecrafts, mission systems engineering, ground software systems and hardware platforms for critical USSF missions.
