This article is based on an official press release from Britten-Norman.

We are tracking a significant milestone in the development of airborne telecommunications. According to a recent press release, UK-based aircraft manufacturer Britten-Norman has completed the structural and engineering preparations necessary to integrate an advanced 5G antenna system onto its BN2T-4S Islander aircraft. This development marks a critical phase in the company’s ongoing collaboration with World Mobile Stratospheric (WMS) to deliver high-speed internet connectivity directly from the sky.

The aircraft is currently stationed at Britten-Norman’s Maintenance, Repair, and Overhaul (MRO) facility, where the installation of the proprietary phased-array antenna is underway. Flight testing is scheduled to commence in the summer of 2026 near Ipswich, UK. The program aims to validate the use of aircraft-based 5G systems to provide real-time mobile coverage to remote communities and rapidly restore communications in disaster-stricken regions.

While the Islander will serve as the initial testbed, industry research indicates that this phase is a vital stepping stone toward a much larger goal: the deployment of autonomous High-Altitude Platform Stations (HAPS) operating in the stratosphere to provide wide-area, direct-to-smartphone connectivity.

Engineering the Airborne 5G Platform

The BN2T-4S Islander Testbed

Adapting a traditional aircraft to carry heavy, high-powered telecommunications equipment presents a complex integration challenge. According to the Britten-Norman press release, the company’s Design Office produced over 100 individual engineering drawings to support the structural analysis, power management, and safe mounting of the antenna system.

Industry data highlights why the BN2T-4S Islander was selected for this rigorous testing phase. Acquired by WMS in November 2025, the BN2T-4S is a larger, turbine-powered variant of the iconic Islander, equipped with twin Rolls-Royce M250-B17F turboprop engines. It features a stretched fuselage that provides 30 percent more internal cabin space than its piston-powered predecessor. With a Maximum Take-Off Weight (MTOW) of 8,925 lbs and an endurance of up to eight flying hours, the aircraft offers the ruggedness and payload capacity required for iterative, real-world data gathering.

“The scale of the design effort reflects the complexity of integrating advanced communications systems onto the Islander platform and demonstrates the depth of engineering capability within Britten-Norman,” stated Mark Shipp, Technical Director at Britten-Norman, in the official release.

Advancing High-Altitude Telecommunications

From Low Altitude to the Stratosphere

The core technology driving this initiative is a highly advanced phased-array 5G antenna. Background research reveals that the system utilizes 500 individually steerable beams, allowing operators to direct targeted, high-speed coverage to specific locations on the ground. The system is designed to deliver connection speeds of 150 to 200 Mbps directly to standard consumer smartphones.

During the upcoming summer 2026 test-flights, the Islander will broadcast over an approximate 15-kilometer radius. However, the ultimate vision for WMS extends far beyond traditional aviation altitudes. The technology is intended for High-Altitude Platform Stations (HAPS), aircraft designed to operate in the stratosphere at altitudes of 60,000 to 70,000 feet. At this height, a single stratospheric platform could eventually cover an area of up to 15,000 square kilometers.

Following successful validation on the Islander, WMS plans to transition the technology to an autonomous, liquid-hydrogen-powered aircraft known as the “Stratomast,” which is projected to sustain flights for up to a week at a time. Test flights for the Stratomast are targeted for 2027.

Strategic Partnerships and Real-World Impact

Connecting the Unconnected

The airborne 5G program is the result of extensive corporate collaboration. World Mobile Stratospheric is a joint venture between US-based telecom provider World Mobile and Indonesian digital infrastructure company Protelindo. The technology itself was originally developed by Stratospheric Platforms Ltd (SPL), which has since been subsumed into WMS.

British Telecom (BT) has also been a foundational partner. Since early 2023, BT has been testing the proprietary 5G antenna at its Adastral Park R&D facility in Suffolk, ensuring seamless integration with secure 5G architectures and Open RAN testbeds. The upcoming flight assessments will be conducted by Britten-Norman’s flight operations team in close cooperation with both WMS and BT.

“We are very happy to have reached this important milestone in our joint work with Britten-Norman to deliver connectivity from the sky – both for disaster resilience using the Islander platform and, ultimately, for wider communications coverage,” said Richard Deakin, CEO of World Mobile Stratospheric.

AirPro News analysis

We view the Britten-Norman and WMS collaboration as a highly pragmatic approach to a notoriously difficult engineering challenge. By utilizing the proven, rugged BN2T-4S Islander as a low-altitude testbed, the consortium can iteratively refine beam stabilization and network integration without the immense costs and risks associated with immediate stratospheric drone testing.

Furthermore, the HAPS concept presents a compelling alternative to Low-Earth Orbit (LEO) satellite constellations like Starlink. While LEO satellites provide global coverage, they often require specialized ground receivers and can suffer from latency issues. The WMS phased-array antenna promises 150 to 200 Mbps directly to standard, unmodified smartphones. If successfully scaled to the stratosphere, this technology could bridge the gap between terrestrial cell towers and satellite networks, offering a highly effective solution for rural “white spots” and rapid disaster response.
