A new mobile space surveillance radar is now active as military planners focus more on tracking potential threats in orbit, including satellites used for nuclear command, control, and intelligence. LeoLabs, a space monitoring company, announced that its latest radar, Scout Hawaii, began operating and will take part in the Valiant Shield 2026 exercise in the Pacific.

This is the first time the company’s Scout-S radar has been used in the field. It is designed to better track objects in low Earth orbit (LEO) and very low Earth orbit (VLEO).

Radar heads to major Pacific military exercise

Valiant Shield is a major joint military exercise held every two years by the United States in the Indo-Pacific. Since 2024, regional allies have also taken part.

This year’s exercise will take place from June 22 to July 1 in Hawaii, Guam, Japan, and nearby waters.

LeoLabs has not shared details about the contract for the radar’s participation. The company said the Scout-S program is funded by private investment and support from the US Space Force, including a Tactical Funding Increase (TACFI) award announced in 2025.

The company views the exercise as an opportunity to test the radar in real-world conditions and demonstrate how it can support military space awareness missions.

A new class of radar is here.

Scout-S delivers persistent custody, dynamic tracking, and deployable sensing for LEO and VLEO — extending coverage where mission demand is greatest.

It's more than a radar. It’s a new approach to space sensing.

Built for rapid deployment anywhere

One of the key features of the Scout-S system is its mobility. The radar fits in a standard 20-foot shipping container, so it can be moved by truck, plane, or ship.

The system uses 3D scanning, direct-radiating-array technology, and a modular S-band electronic system. LeoLabs said these features help the radar find and track objects in busy orbital areas.

A company spokesperson said the improved design greatly increases how long the radar can observe a satellite as it passes by.

From snapshots to continuous tracking

Traditional tracking systems usually watch satellites for only short periods before waiting for the next pass. LeoLabs said Scout-S is built to provide much longer observation periods, helping operators track objects in orbit more continuously.

The company thinks this feature is more important now that military and commercial satellites can maneuver more often.

“The acceleration of adversarial activity in space is challenging U.S. and Allied Space Superiority. Tracking objects periodically to predict orbits is no longer enough. What matters now is the ability to maintain persistent custody of maneuverable payloads so our customers can respond to emerging threats,” said LeoLabs CEO Tony Frazier in the release.

The design also allows multiple units to be deployed quickly, helping to cover surveillance gaps that fixed radar sites cannot easily reach.

Tracking Chinese satellites and future expansion

Scout Hawaii is already sending data to LeoLabs’ global monitoring network. The company said the radar has consistently tracked Chinese intelligence, surveillance, and reconnaissance satellites, including the Yaogan military spacecraft.

According to the firm, the system has tracked China’s reusable spaceplane in low Earth orbit. The radar has also shown it can monitor objects flying at very low altitudes. The company reported successfully tracking an object orbiting at 143 miles (230 kilometers) above Earth.

The firm plans to keep the Hawaii-based radar running after Valiant Shield ends, using it for more experiments and testing new features. The company also said a second Scout-S unit should be built by early 2027, with more production expected later that year.

A possible agreement to end the war between the United States and Iran was announced late Sunday by U.S. President Donald Trump and Pakistani Prime Minister Shehbaz Sharif.

The deal includes stopping military actions, reopening the Strait of Hormuz, and eventually lifting U.S. restrictions on Iranian ports. Still, Iran’s nuclear program, a key issue, has not been settled and will be discussed in future talks.

The agreement is expected to be officially signed in Switzerland on Friday. News of the deal quickly affected global markets, sending oil prices down and Asian stock markets higher.

Ceasefire framework signals end to active fighting

The U.S. president announced the agreement on his Truth Social platform at about 5:30 p.m. ET on Sunday, saying, “The Deal with the Islamic Republic of Iran is now complete.” His statement came after Sharif spoke, as Pakistan has helped mediate the talks.

Although all the details have not yet been shared, Sharif said the agreement includes “the immediate and permanent termination of military operations on all fronts, including in Lebanon.”

Iran’s Supreme National Security Council later confirmed that military operations would stop for good starting Monday night. Iranian Deputy Foreign Minister Kazem Gharibabadi said negotiators will use a 60-day ceasefire to work toward a broader agreement that could include easing sanctions and other long-term measures.

This announcement follows months of fighting that have killed thousands, mostly in Iran and Lebanon. After U.S. and Israeli attacks on Iran on February 28, Tehran struck Israel and Gulf countries with U.S. bases. Iran also blocked shipping in the Strait of Hormuz, and the U.S. responded by restricting Iranian ports.

A major result of the agreement is the planned reopening of the Strait of Hormuz, which is a key route for global oil and gas shipments. Trump said the waterway will reopen on Friday and that he has ordered the U.S. blockade of Iranian ports to end.

“Ships of the World, start your engines. Let the oil flow!” Trump wrote.

Nuclear dispute remains the biggest challenge

Even with this diplomatic progress, negotiators have delayed decisions about Iran’s nuclear activities.

According to Iranian officials, discussions during the ceasefire period will focus on sanctions relief and the future of Tehran’s nuclear program. Sources indicate that the issue remains among the most difficult issues facing both sides.

The dispute goes back years. During Trump’s first term, the U.S. withdrew from the 2015 nuclear deal negotiated under President Obama. After that, Iran increased its uranium enrichment and built up more than 400 kilograms (about 900 pounds) of uranium close to weapons-grade.

Former Biden administration State Department spokesperson Matthew Miller criticized the framework, saying: “We have no assurances the nuclear program will ever be addressed, but Iran has shown the world it can take the global economy hostage and get something from the U.S. in return.”

Republican Senator Lindsey Graham welcomed the ceasefire but stressed that future nuclear talks will be watched closely. “Under our law, any nuclear deal with Iran will be sent to Congress for review and a vote,” he said. “Congratulations to all on getting us to this point.”

As negotiators prepare for formal talks in Switzerland, the focus is now on whether the ceasefire will last and if both sides can agree on Iran’s nuclear future.
