US Space Force Battles China's "Orbital Hide-and-Seek" with Advanced Maui Surveillance Complex

Hawaii facility emerges as critical asset in growing space surveillance rivalry as China deploys deceptive satellite tactics

MAUI SPACE SURVEILLANCE COMPLEX, Hawaii — High atop the 10,023-foot summit of Haleakala volcano, the U.S. Space Force's most advanced surveillance telescopes are locked in an increasingly sophisticated game of orbital cat-and-mouse with China, as Beijing develops new capabilities to hide its satellite activities from American detection systems.

General Chance Saltzman, Chief of Space Operations, revealed this week that China is "intentionally trying to do things" in space "so we don't see it," employing tactics ranging from changing satellite brightness to maneuvering in what Beijing believes are U.S. blind spots. Speaking during a rare visit to the Maui Space Surveillance Complex, Saltzman emphasized the escalating challenge: "We've got to keep pace, and we've got to keep advancing our capabilities so that that's harder and harder for them to do."

The Strategic High Ground

The Maui facility represents what military officials call the "third-best place to put a telescope in the world" and the optimal location for daylight sky observations. Positioned above Maui's cloud layer with crisp, clear air and minimal light pollution, the complex provides unparalleled views of satellites and space objects across the Pacific region.

"From a space perspective, this particular piece of land is pretty important because some of the work you can do here, you just can't do elsewhere," Saltzman said. The strategic location allows surveillance of geostationary satellites hovering over the Pacific, with sight lines extending from the U.S. West Coast to mainland China.

The centerpiece of operations is the Advanced Electro-Optical System (AEOS) telescope, a 75-ton, 3.67-meter instrument that ranks as the Department of Defense's largest optical telescope. Built in the 1990s, the massive telescope can rotate quickly enough to track low-Earth orbit satellites and ballistic missiles, though it captures only about 10 percent of a satellite's total orbital path.

China's Deceptive Space Maneuvers

Recent intelligence reveals the sophisticated nature of China's space deception efforts. The Space Force has deployed secretive "situational awareness indications and warning payloads" aboard satellites since 2023 that have been "collecting all kinds of very interesting data on the Chinese SOSI [Space Observation Surveillance and Identification System] network" — Beijing's equivalent to Washington's Space Surveillance Network.

The orbital surveillance rivalry reached new heights in September when China's Jilin-1 satellite constellation captured images of a U.S. WorldView Legion satellite that was itself monitoring Chinese space assets, marking "the first time Chang Guang had made public such dynamic space-based imagery." This tit-for-tat demonstration occurred after Maxar Intelligence had earlier published detailed images of China's advanced Shijian-26 reconnaissance satellite.

Colonel Barry Croker, who leads the Space Force's domain-awareness efforts under Mission Delta 2, noted the fundamental challenge: "We built a really great system for telling us where things were. It's difficult to know where things are going to be." The problem intensifies when satellites maneuver immediately after leaving observation windows, potentially ending up far from predicted locations.

Technological Arms Race

China has demonstrated remarkable advances in surveillance technology, including new laser-imaging satellites "powerful enough to capture human facial details from more than 60 miles (100 kilometers) away" — a 100-fold improvement over traditional spy cameras. This synthetic aperture lidar technology could enable unprecedented surveillance of foreign satellites and ground targets.

China's Yaogan-41 surveillance satellite, launched in December 2023, "may allow it to keep watch around the clock on the entire Indo-Pacific region from geostationary orbit," potentially tracking "car-sized objects throughout the entire Indo-Pacific region."

The complexity extends beyond simple tracking. U.S. officials have observed Chinese satellites "maneuvering in and out and around each other in synchronicity and in control," demonstrating capabilities that could be used to capture or disable other nations' spacecraft.

Modernization Under Pressure

The Maui complex is undergoing critical upgrades to meet evolving threats. Three Ground-Based Electro-Optical Deep Space Surveillance Systems telescopes are receiving modernized "sensors, optics, algorithms, and post-processing of the data so they can 'see smaller, dimmer things further' into space." The Maui upgrade is expected to be completed by April 2026 or later.

In February 2025, KBR Inc. received a $176 million seven-year contract to provide "operations and equipment maintenance support, site modernization, and recapitalization to the existing legacy space domain awareness capabilities at Maui."

The facility now tracks over 40,000 objects in space, a mission that began during the Cold War but has transformed dramatically as space evolved from a peaceful domain to a contested warfighting environment.

Cultural and Environmental Challenges

The expansion faces significant local opposition. Native Hawaiians consider Haleakala sacred, and Space Force proposals for up to seven additional telescopes on the summit have met with protests. A 2023 diesel fuel spill of 700 gallons further angered local communities.

Saltzman acknowledged these concerns, stating the Space Force is "honored to be associated" with Haleakala and is "fully committed to respecting the mountain's cultural and spiritual significance and moving forward only in complete partnership with the community."

Space Domain Awareness Evolution

Saltzman has pushed for a "comprehensive program" rather than incremental improvements, noting that "space domain awareness capabilities are struggling to keep pace" with exponential growth in space congestion. The Space Force increased its space domain awareness budget by nearly 30 percent, from $373 million to $484 million.

The mission encompasses three core objectives in Saltzman's "theory of success": avoid operational surprise, deny first-mover advantage, and confront malign activity. Space domain awareness underpins all three goals.

Future Implications

Saltzman emphasized that the Space Force is now "really recognizing" that "space is a contested warfighting domain," driving priorities including space domain awareness, resilience, and capabilities to "hold at risk" adversary space assets.

As the orbital environment grows increasingly crowded and contested, the Maui Space Surveillance Complex stands as a critical sentinel, its powerful telescopes peering through Earth's atmosphere to track the subtle movements and deceptions of an new kind of warfare — one played out in the silence of space, 200 miles above the Pacific Ocean.

"If you're going to do something irresponsible, we're going to see it. We're going to tell the world, and then we're going to react and respond," Saltzman declared, a promise that depends heavily on the continued advancement of facilities like the one perched atop this Hawaiian volcano.
