U.S. Space Force Awards Contract for On-Orbit Vehicles Refueling Program
The United States Space Force (USSF) awarded Northrop Grumman Corporation two national security contracts, including a technology demonstration for in-space refueling. These contracts build on Northrop Grumman's on-orbit satellite servicing and refueling innovation, including first-of-its-kind mission extension services that protect critical space assets in geosynchronous orbit for both U.S. government and commercial partners.

Space Systems Command (SSC) awarded Northrop Grumman a contract for the Elixir refueling payload program, which will enable the Space Force to refine tactics and procedures for rendezvous and proximity operations, docking, refueling, and undocking of on-orbit vehicles -- foundational capabilities for servicing, mobility and logistics.
Under the Elixir program contract, the company will design, build and integrate a refueling payload onto a space vehicle and demonstrate refueling with a demonstration client satellite.
Under a separate contract, Northrop Grumman has been awarded a multi-unit award of four of the company's proven ESPAStar spacecraft, one of which will host the refueling demonstration payload on its ride to space.

Lauren Smith, program manager for in-space refueling at Northrop Grumman said "This technology will unlock new possibilities for dynamic space operations, providing the sustained maneuverability our customers need in a complex environment. To deliver this critical national security capability, our team will build on Northrop Grumman's in-space servicing success and trailblaze new refueling solutions to meet mission needs."
The USSF has made a multi-unit ESPAStar purchase, underscoring the increasing demand for rideshare vehicles and rapid access to space. Since its first award in 2016, the ESPAStar product line has provided proven and reliable capability. Each upgraded bus can hold more than 330kg of payload mass on each of its six ports, providing additional mass-to-orbit.
The Elixir program includes elements to successfully perform rendezvous and proximity operations, dock and undock with a demonstration client satellite, to transfer and receive fuel. The refueling payload will be equipped with the company's Active Refueling Module (ARM), which interfaces with Northrop Grumman's Passive Refueling Module (PRM) for the transfer and receipt of fuel. Operational client satellites equipped with PRMs will benefit from this mature technology because they can be refueled.

Matt Verock, Vice President, Space Security Systems, Northrop Grumman: "Northrop Grumman's refueling capabilities are pioneering the next generation of satellite technology. The ability to refuel on orbit will have a direct impact on the success of our nation's most important missions -- allowing warfighters to continue operating quickly and safely."
