美国航空航天公司Sceye开发的无人平流层飞艇于2026年8月至9月间成功完成了从新墨西哥州到日本的往返飞行1。该飞艇采用氦气浮力和电动螺旋桨推进，搭载太阳能电池板和电池系统，旨在验证其作为空中基站的可行性1。
飞艇在60,000英尺（约18,290米）的高度保持了稳定悬停1。Sceye首席执行官Mikkel Frandsen表示："我们能在平流层约60,000英尺处停留在一个作业区域，我们的高度是航空交通的两倍，在喷气流之上，但比低轨卫星近30倍"1。
U.S. aerospace company Sceye successfully conducted a round-trip flight of an unmanned stratospheric airship from New Mexico to Japan between August and September 2026, lasting approximately one month.1 The vehicle, which operated at an altitude of 60,000 feet, was designed to test the viability of high-altitude platforms functioning as airborne cellular towers.1
The airship employed helium for lift and electric propellers for propulsion, supplemented by solar panels and battery systems to enable sustained operations.1 According to CEO Mikkel Frandsen, the platform's operational altitude offers significant advantages: "We can loiter in a work area at roughly 60,000 feet in the stratosphere, we're twice the altitude of air traffic, above jet streams, but 30 times closer than low-orbit satellites."1 The aircraft was based near Albuquerque in New Mexico.1
The mission demonstrated Sceye's technology for maintaining stationary positioning at extreme altitude, a capability intended to support telecommunications and other applications where extended hovering at high elevation proves beneficial.
