Northrop Grumman CEO: Whether MRV satellite can be used to attack other satellites is up to US government

A spacecraft equipped with two robotic arms, developed by Northrop Grumman, is scheduled for launch today. The company plans to establish an entire fleet of these Mission Robotic Vehicles (MRVs), ostensibly to offer a commercial service for refueling and repairing satellites in orbit. However, questions have been raised about whether the MRV could also be used to attack enemy assets in space. The U.S. Space Force has publicly stated it is pursuing offensive space-based capabilities, primarily to help protect friendly satellites from growing threats.

Earnings Call Raises Offensive Use Question

Whether the MRV—or a derivative thereof—could be employed in an offensive role explicitly came up during a quarterly Northrop Grumman earnings call this morning. The company does not appear to have ruled out the possibility.

"As part of our satellite servicing portfolio, we've developed the first commercial robotic spacecraft capable of repairing, relocating, and servicing satellites in geosynchronous orbit via two robotic arms," Northrop Grumman CEO Kathy Warden highlighted in her introductory remarks at the start of the call. "It can also install life extension jetpacks onto other satellites for government or commercial customers, prolonging their useful life for up to eight years."

"The spacecraft is known as the Mission Robotic Vehicle, or MRV, and our first MRV is scheduled to launch later today, weather permitting," she added.

"You probably can't provide quantitative terms here, but just from a qualitative perspective, what's the potential market for an offensive version of that spacecraft that could be used to disable adversary satellites?" asked Scott Mikus, Director for Aerospace, Defense and Space Research at Melius Research, later during the call.

"So I appreciate the question. I will leave it up to the U.S. government to decide how that capability might fulfill mission objectives that they have in that regard," CEO Warden responded. "But certainly, it's our objective to offer our clients options for technology deployment, and for them to determine policy for when and how they might deploy that technology."

Launch Details

If all goes to plan, a SpaceX Falcon 9 rocket carrying the MRV will blast off from Cape Canaveral sometime in a four-hour window starting at 5:15 PM ET today. The rocket will also carry three Mission Extension Pods (MEPs), which are the "life extension jetpacks" that Warden mentioned.

Technical Capabilities and Dual-Use Concerns

The MRV has two robotic arms that allow it to place the MEPs onto other satellites in orbit, as well as perform other tasks. The arms are part of what is formally called the Robotic Servicing of Geosynchronous Satellites (RSGS) payload. The RSGS system was developed through a program led by the U.S. Defense Advanced Research Projects Agency (DARPA), in cooperation with the U.S. Naval Research Laboratory (NRL). It is worth noting that RSGS is the product of U.S. government work in this vein stretching back decades. There have also been other similar developments globally, including in China and Russia.

The MRV's upcoming mission will include rendezvousing with satellites belonging to Australian firm Optus and Luxembourg-based SES and attaching MEPs to them, according to a report from Spaceflight Now. Both companies are commercial telecommunications providers.

Northrop Grumman's fact sheet on the MRV states the spacecraft is capable of performing an array of on-orbit inspection and servicing missions beyond refueling via the MEPs. The robotic vehicle can also be used to "tow" satellites from one position to another and help clear debris. All of this requires the ability to maneuver very closely with other target objects in space—which brings us to the question of the MRV potentially offering an offensive anti-satellite capability.

Inherently Dual-Use Technology

For years, TWZ has highlighted how robotic arms on spacecraft are an inherently dual-use capability that could be used to launch attacks in space. In general, arms like this could be used to damage or destroy key systems on adversary satellites, such as optics or solar panels, or to pull them out of orbit. In the latter case, the target could be towed into a degrading orbit where, if control could not be reestablished, it would re-enter Earth's atmosphere and be destroyed.

The U.S. military itself has repeatedly pointed to adversary satellites with robotic arms as one of many potential threats to its own space-based capabilities.

"We're basically responding to a warfighting domain where our adversaries have already put interceptors in space, and we want to make sure that we rebalance that in terms of deterrence," said the Chief of Space Operations.
