Sceye's ST1 HAPS Completes 30,000km Round Trip to Japan for SoftBank

Moriarty, New Mexico – September 16, 2026 -- Sceye's stratospheric platform ST1 has completed a nearly 30,000-kilometer round trip between New Mexico and Japan, re-entering continental U.S. airspace on September 16, 2026, and reaching the company's Moriarty headquarters the following day for final testing and controlled descent.

ST1 logged over seven days in Japanese controlled airspace during a month-long mission

The high-altitude platform station (HAPS), developed with SoftBank Corp. (TOKYO: 9434), marked Sceye's first flight into Asia and a key step toward commercial HAPS deployment. ST1 maintained a station-keeping radius of just 5 kilometers off the Japanese coast while operating continuously at 16.5 to 17 kilometers altitude.

Moriarty, New Mexico – September 16, 2026 -- Sceye's ST1 high-altitude platform has completed a nearly 30,000-km round-trip mission between New Mexico and Japan, landing back near the company's Moriarty headquarters after re-entering continental U.S. airspace on September 16, 2026. The uncrewed stratospheric aircraft reached New Mexico airspace on September 16, 2026, where engineers ran final platform tests before executing a planned flight-termination and descent procedure.

Moriarty, New Mexico – September 14, 2026 -- Sceye's ST1 high-altitude platform completed a nearly 30,000 km round-trip flight from New Mexico to Japan and back, re-entering continental U.S. airspace on September 14, 2026 and reaching Moriarty, New Mexico on September 14, 2026, where the company conducted final vehicle testing and a planned descent.

ST1 marks Sceye's first flight to Asia in partnership with SoftBank

The month-long mission was conducted with SoftBank Corp. (TOKYO: 9434) and represents Sceye's first flight into Asian airspace. ST1 carried SceyeCELL, described as a first-of-its-kind stratospheric "cell tower in the sky" built to deliver wide-area mobile broadband directly to standard devices. At full scale, one Sceye HAPS is designed to cover an area equivalent to roughly 500 terrestrial towers.

Tokyo – September 08, 2026 -- Sceye's Service Test 1 (ST1) stratospheric platform completed a transpacific flight of more than 15,000 kilometers from New Mexico to Japan in 13 days, demonstrating mobile broadband connectivity through SoftBank Corp.'s core network using unmodified consumer devices.

Sceye and SoftBank achieve 68-millisecond round-trip latency using onboard edge computing

The mission installed a server directly on the high-altitude platform system (HAPS), enabling data processing to occur onboard rather than through internet-based cloud infrastructure. This cut communication latency by more than 40% compared to cloud processing, marking what the companies describe as the first global test of a mobile core network and web server installed on a HAPS.

Tokyo – September 07, 2026 -- Sceye's Service Test 1 (ST1) stratospheric platform completed a 15,000-km flight from New Mexico to Japan in 13 days, marking the company's first Asia deployment and a milestone toward commercial High-Altitude Platform Systems (HAPS) infrastructure.

Conducted with SoftBank Corp. (TOKYO:9434), ST1 launched August 9, 2026, at 7:00 AM MDT and operated within Japanese airspace for over seven days, maintaining a station-seeking radius as low as 5 km while flying at approximately 16.5 km altitude.

Sceye's ST1 mission cut cloud-processing latency by more than 40%

The Service Test 1 (ST1) aircraft carried a server onboard the platform, achieving an average round-trip processing response time of 68 milliseconds. Sceye said this marked the world's first test in which a mobile core network and web server were installed directly on a High-Altitude Platform System (HAPS), allowing response processing to occur onboard before results were relayed to smartphones.
