The Department of the Air Force announced on May 6 that it has awarded a research contract to Overview Energy, a privately held firm headquartered in Ashburn, Virginia, to evaluate how space‑based solar generation could be used to power U.S. military sites. The award, issued by the Secretary of the Air Force for Installation, Energy and Environment, is intended to determine whether solar panels placed in geostationary orbit and coupled with high‑energy infrared lasers can supply reliable electricity to installations that are difficult to fuel, such as Eielson Air Force Base near Fairbanks, Alaska, and Andersen Air Force Base on Guam. The contract’s monetary value and the length of the study were not disclosed.
Overview Energy’s approach envisions a constellation of solar collectors orbiting at roughly 35,800 kilometres, where uninterrupted sunlight can be harvested. The harvested power would be converted into a laser beam and directed toward ground‑based solar farms equipped with receivers that reconvert the light into electricity, allowing the facilities to run even when the sun is not shining. The company has already demonstrated the laser‑beaming concept from an aircraft and is targeting a full‑scale orbital test in 2028.
The idea of delivering power from space to forward operating locations is not new. In 2007, the Pentagon’s National Security Space Office released a study that identified remote bases as a potential first market for space solar power. At the time, the analysis suggested that the Department of Defense might be willing to pay a premium—above $1 per kilowatt‑hour—to avoid the logistical and security risks associated with fuel convoys. The Iraq conflict of the early 2000s underscored those risks, as fuel trucks were frequent targets of insurgent attacks. Although the 2007 report recommended further investigation, it also concluded that the business case was weak because launch costs were prohibitively high.
Since then, the economics of access to orbit have shifted dramatically. Marc Berte, chief executive of Overview Energy, told a SpaceNews gathering on April 30 that launch prices have fallen from tens of thousands of dollars per kilogram to roughly $1,000 per kilogram today, and that emerging heavy‑lift systems such as SpaceX’s Starship could push the cost down into the low‑hundreds of dollars per kilogram. Those reductions, he argued, are the single most important factor that has revived interest in orbital power generation.
Laser technology has progressed in parallel. Modern solid‑state and fiber‑laser systems can now produce continuous‑wave beams with efficiencies that make the concept of space‑to‑ground power transfer more plausible. By leveraging existing solar‑farm infrastructure as the ground‑side receiver, the model avoids the need for dedicated power‑conversion stations, potentially lowering capital expenditures.
The defense implications are significant. Fuel logistics for isolated installations have long been a strategic vulnerability; a reliable, non‑fuel‑based power source could reduce the footprint of supply convoys, lower exposure to hostile action and free up transport assets for other missions. Moreover, a resilient energy supply could enable longer endurance for forward‑deployed sensors, communications gear and unmanned systems, thereby expanding the operational envelope of the warfighter.
Beyond the military, Overview Energy has already begun courting commercial customers. In late April, the company announced a memorandum of understanding with Meta Platforms to provide up to one gigawatt of orbital‑derived power for the social‑media giant’s data centers. That partnership signals that the technology may soon be viewed as a viable component of the broader energy‑infrastructure mix, especially for high‑density computing facilities that demand uninterrupted power.
The contract also opens opportunities for established aerospace and defense contractors. Companies such as Lockheed Martin (LMT), Northrop Grumman (NOC), Raytheon Technologies (RTX) and Boeing (BA) possess the launch integration, satellite bus design and high‑power RF/laser expertise that could be called upon to support a future operational system. Meanwhile, commercial launch providers like Rocket Lab (RKLB) and emerging players developing reusable heavy‑lift vehicles are positioned to benefit from the anticipated increase in demand for low‑cost payload delivery.
From a geopolitical standpoint, the United States is seeking to maintain a technological edge in space‑based capabilities that could have both civilian and military utility. If the Air Force’s study confirms that orbital solar power can be delivered at acceptable cost and reliability, it may pave the way for a new class of strategic assets that are less vulnerable to conventional anti‑access/area‑denial tactics. Such a development would be of interest to allies that share forward‑deployment responsibilities, potentially leading to joint procurement or technology‑sharing arrangements.
The initiative also arrives at a time when other nations are exploring similar concepts. China’s space program has hinted at high‑power microwave transmission experiments, while the European Union has funded research into space‑derived energy for remote islands. The United States’ renewed focus could therefore shape standards and export controls around high‑energy laser transmission, influencing the global market for related components.
In summary, the Air Force’s contract with Overview Energy marks a concrete step toward revisiting a long‑standing vision of space‑based power as a strategic enabler for remote operations. The convergence of cheaper launch services, mature laser technology and growing commercial appetite creates a fertile environment for the concept to move beyond theory. While the study’s outcomes remain to be seen, the partnership underscores a broader shift in how policymakers and industry leaders view space—not merely as a domain for communications or surveillance, but as a potential backbone for critical infrastructure.
The next few years will likely see a series of technical milestones, including the 2028 orbital demonstration that Overview Energy has slated. Success could trigger a cascade of contracts, not only within the defense establishment but also across the private sector, reshaping the economics of both energy delivery and space operations.
