SNC Successfully Completes Global Stratospheric ISR Flight for U.K.’s Project Aether

SNC demonstrates rapidly deployable High-Altitude Balloon for uninterrupted ISR

SPARKS, Nev., October 26, 2022 – Sierra Nevada Corporation (SNC) successfully demonstrated performance of its rapidly deployable High-Altitude Balloon (HAB), completing launch, mission performance and recovery of the uncrewed platform for stratospheric communications and intelligence, surveillance and reconnaissance (ISR). The flight was a critical part of the company’s U.K. Ministry of Defence’s (MOD) Project Aether Flight 1 Assessment Phase contract. SNC’s rapidly HAB provides global, persistent and uninterrupted ISR with communication capabilities at higher altitudes in near real-time.

“We are very pleased with the successful results of this demonstration,” said Tim Owings, executive vice president of SNC’s Mission Solutions & Technologies (MST) business area. “SNC has extensive experience working with researchers and industry on high-altitude C5ISR technologies and this demonstration simply reinforces our commitment to delivering superior development, integration and deployment services to customers around the globe.”

SNC’s Flight 1 demonstration launched from Page, Ariz., performing key station-keeping missions before transitioning northeast across several states to more urban environments. The HAB’s solar arrays and batteries provide the power needed to integrate larger payloads, expanding mission opportunities and enhancing available mission capabilities. It is also capable of around-the-clock operations, exploiting the natural speed and directional diversity of stratospheric winds. SNC successfully performed all stratospheric beyond-line-of-sight operations and recovered the payload for the duration and altitudes set by the Aether programme office.

Project Aether will address the MOD’s need for rapidly maneuverable, ultra-persistent wide area communications and ISR for long-duration missions with minimal resupply or maintenance efforts. SNC’s system is capable of targeting geolocations anywhere in the world and offers immediately available and exploitable data using a range of existing resources.

“Our team is very excited to be working with the UK MOD on this project,” said Bill Leonard, senior director of programs for SNC’s MST business area. “SNC has considerable experience with these ‘lighter than air’ high-altitude platforms and collection systems. We are confident that our HAB both meets and exceeds the mission requirements of our MOD customer, as well as other SNC partners around the world.”

Partnered with SNC subsidiary, Sierra Nevada Corporation Mission Systems UK (SNC MS UK), World View Enterprises, Inc. and Digital Receiver Technology, Inc., the SNC-led team leverages a commercially mature platform and tools proven at the highest technology readiness level (TRL-9). The next phase of demonstrations will include a 60-day test flight.
