Sceye’s 270‑foot helium‑filled airship, launched from Albuquerque on 9 August 2026, flew more than 9,300 miles to Shikoku, Japan, before returning to the United States. The mission, dubbed Service Test 1, was the longest yet for a high‑altitude platform system (HAPS) and proved the vehicle can hover, navigate autonomously and provide live cellular service from the stratosphere.
The platform, which uses solar panels and batteries to stay aloft for 24 hours, carries a 4G LTE base‑station payload that SoftBank Corp. deployed over Shikoku. During the flight, the HAPS supplied voice, text, web and video services to smartphones, laptops and drones, and demonstrated emergency‑alert and maritime‑communication capabilities.
"We can stay over an area of operation, and we do that in the stratosphere right around 60,000 feet, so we’re twice as high as air traffic and we’re above the jet stream, and yet 30 times closer than low‑Earth‑orbit satellites," said Sceye founder and CEO Mikkel Frandsen.
The airship’s autonomous navigation system allowed it to adjust its path in real time, parking in safe zones when weather deviated from the planned trajectory. The mission also tested laser‑based optical links between the stratosphere and ground stations, suggesting a future role as a relay between low‑Earth‑orbit satellites and terrestrial infrastructure.
Sceye’s current model can lift payloads of 220 lb (100 kg) and deliver up to 1 kW of power. The company aims to scale to a 551‑lb (250 kg) payload, which would give it 25–50 times the capacity of competing stratospheric drones. Such a platform could provide broadband coverage equivalent to 500 ground‑based cell towers, useful for commercial telecoms and disaster response.
Market analysis
Sceye’s successful trans‑Pacific flight signals a tangible step toward commercial stratospheric networks. Investors are likely to view the HAPS as a niche yet scalable alternative to satellite constellations, offering lower latency and higher data rates for regional coverage. Telecom operators, such as SoftBank, may adopt HAPS to enhance disaster resilience and fill coverage gaps in remote or underserved areas.
The technology could also attract interest from defence and maritime sectors, where high‑altitude platforms can provide secure, low‑latency links for command and control, as well as real‑time situational awareness. The laser‑link trials hint at a future market for stratospheric‑to‑satellite relays, potentially reducing the cost and complexity of ground‑station infrastructure.
If Sceye succeeds in scaling its payload and power capabilities, it could open a new revenue stream for aerospace firms and telecom operators alike, positioning the company as a key player in the emerging HAPS ecosystem.
