SoftBank and TOPPAN Develop Lightweight Wing Skin for Stratospheric HAPS
SoftBank and TOPPAN created an ultra-lightweight, durable wing skin for solar-powered HAPS aircraft to withstand extreme stratospheric conditions.

This article is based on an official press release from TOPPAN Holdings and SoftBank Corp.
SoftBank and TOPPAN Unveil Ultra-Lightweight Wing Skin for Stratospheric HAPS Aircraft
In a significant step toward the realization of 6G “flying base stations,” SoftBank Corp. and TOPPAN Holdings Inc. have announced the joint development of an ultra-lightweight, highly durable wing skin. According to a joint press release issued on April 27, 2026, this new material is specifically engineered for solar-powered High-Altitude Platform Station (HAPS) aircraft.
HAPS vehicles are uncrewed aircraft designed to operate in the stratosphere at an altitude of approximately 20 kilometers. By functioning as airborne telecommunications towers, they offer broader geographic coverage than traditional ground-based cell sites and deliver higher-volume, lower-latency connectivity than satellite networks. We anticipate these platforms will become crucial for disaster recovery and bridging the digital divide in remote regions.
The newly developed wing skin solves a major physical bottleneck in sustained stratospheric flight, combining extreme weather resistance with the strict weight requirements necessary for solar-powered aviation.
Engineering for the Edge of Space
The Stratospheric Challenge
Operating at 20 kilometers above sea level exposes aircraft to environmental extremes that rapidly degrade conventional aerospace materials. According to the project’s technical data, temperatures in the stratosphere can plummet to between -50°C and -95°C, while surfaces exposed to direct sunlight can heat up to 100°C.
Furthermore, the stratosphere features intense shortwave deep ultraviolet (UV-C) radiation and high-concentration ozone levels ranging from 10 to 20 parts per million. The press release notes that these harsh conditions typically destroy the structural integrity of standard all-purpose films, making long-endurance flights nearly impossible without specialized shielding.
Adapting Packaging Technology for Aerospace
To overcome these environmental hurdles, TOPPAN utilized its proprietary “converting technology”, a sophisticated process originally developed for consumer packaging films that involves precise printing and lamination.
“By layering proprietary materials over an impact-resistant base resin designed for extreme cold, they created a skin that resists tearing and degradation,” the project documentation states.
Crucially, the joint announcement confirms that despite the added durability and multi-layered protection, the new skin weighs the same as or less than conventional aircraft skins. This weight efficiency is a mandatory requirement for HAPS aircraft, which rely entirely on solar power and must remain as light as possible to maintain sustained flight.
A New Standard in Material Testing
The partnership between the telecom giant and the materials manufacturers also yielded a breakthrough in aerospace testing methodologies. Historically, testing materials for stratospheric conditions on the ground has been difficult due to the complex interplay of extreme cold, radiation, and atmospheric gases.
According to the release, TOPPAN engineered a novel testing infrastructure capable of simulating the stratosphere’s unique environment. This new facility simultaneously exposes materials to cryogenic temperatures, shortwave UV rays, and high ozone concentrations. This allows engineers to accurately observe and measure stratospheric degradation mechanisms without needing to launch test flights.
SoftBank played a critical role in this phase by providing real-world stratospheric data gathered from its previous HAPS flight operations. SoftBank supplied exact temperature profiles and UV-C exposure metrics, while also defining the strict weight and aerodynamic performance requirements for the final material.
Commercialization Timeline and Strategic Goals
The companies have outlined a clear roadmap for bringing this technology to market. Throughout fiscal 2027 (ending March 2028), SoftBank and TOPPAN will continue their research to make the current skin material even lighter and stronger. By fiscal 2028, the partners target the establishment of mass-production technology to ensure reliable quality and sufficient supply.
Official commercial services utilizing this new wing skin on SoftBank’s heavier-than-air (HTA) HAPS aircraft are slated to launch in 2029. Additionally, both companies stated they are exploring broader applications for this highly durable material in other industries that require extreme weather resistance.
AirPro News analysis
We view this partnership as a critical indicator of two major industry trends. First, it highlights SoftBank’s comprehensive, dual-track approach to stratospheric infrastructure. While the telecom company invested $15 million in U.S.-based aerospace firm Sceye in June 2025 to deploy lighter-than-air (LTA) airships for pre-commercial services in Japan starting in 2026, this TOPPAN collaboration secures the supply chain for its heavier-than-air (HTA) fixed-wing aircraft targeted for 2029. SoftBank is effectively hedging its bets across different aerodynamic platforms to ensure dominance in the emerging 6G landscape.
Second, this development underscores TOPPAN’s strategic corporate pivot. Historically recognized as a traditional printing and packaging giant, TOPPAN is successfully leveraging its legacy converting and lamination technologies to penetrate high-value, advanced sectors like aerospace materials and digital solutions. By solving a complex aerospace engineering problem with adapted consumer packaging technology, TOPPAN is positioning itself as a vital player in next-generation telecommunications infrastructure.
Frequently Asked Questions (FAQ)
What is a HAPS aircraft?
High-Altitude Platform Stations (HAPS) are uncrewed, often solar-powered aircraft that fly in the stratosphere (around 20 kilometers above Earth). They act as “base stations in the sky,” providing wide-area cellular and internet coverage to the ground below, making them ideal for disaster recovery and connecting remote areas.
Why is the stratosphere so difficult for aircraft materials?
The stratosphere presents a combination of extreme environmental hazards. Materials must survive temperature swings from nearly -100°C to 100°C, intense UV-C radiation that breaks down chemical bonds, and highly concentrated ozone (10-20 ppm) that accelerates material degradation.

“KBR’s PureSAF is a feed-flexible, bankable technology that is designed to deliver high SAF yields and supports the project across the full lifecycle. We look forward to closely collaborating and supporting the successful execution of this landmark SAF project,” Ibrahim said.
Kazakhstan’s Aviation Decarbonization Strategy
The KBR contract follows a series of government initiatives aimed at building a domestic SAF supply chain. On August 4, 2026, Kazakh Prime Minister Olzhas Bektenov and Dr. Peter Lee of Hong Kong-based Full Vision Capital signed a memorandum of understanding to explore creating a green aviation fuel ecosystem in the city of Alatau. This proposed ecosystem would cover the full production cycle, from cultivating agricultural feedstock to manufacturing the finished product.
These infrastructure investments align with recommendations from global aviation regulators and industry groups. In April 2026, the International Air Transport Association (IATA) emphasized that continued investment in SAF, alongside new airport infrastructure, is critical for Kazakhstan to capitalize on global passenger and cargo traffic and strengthen its domestic aviation sector.
AirPro News analysis
The KBR contract award represents a concrete technical step in Kazakhstan’s ambition to localize SAF production, but several commercial variables remain undefined. The August 24 announcement did not disclose the financial value of the engineering contract, the projected production capacity of the facility, or a target completion date. We note that while the alcohol-to-jet pathway is a proven method for SAF production, scaling agricultural feedstock supply-chain domestically will be critical to the plant’s long-term viability. The parallel involvement of Full Vision Capital suggests the government is actively working to finance and structure this agricultural supply chain in the Alatau region to ensure the KBR-designed facility has the necessary inputs to operate at scale.

Archer Aviation and AEG announce a multi-year partnership to develop an eVTOL vertiport at LA LIVE ahead of the 2028 Olympics.

Archer Aviation Inc. and Anschutz Entertainment Group (AEG) have established a multi-year partnerships to construct a dedicated vertiport for electric vertical takeoff and landing (eVTOL) aircraft at the L.A. LIVE district in downtown Los Angeles.
Announced in an August 24, 2026 press release, the agreement establishes Archer as the exclusive air taxi partner for the 4 million-square-foot sports and entertainment complex. The project serves as a central node for Archer’s planned Southern California network, targeting operational readiness ahead of the 2028 Olympic and Paralympic Games.
Infrastructure and Network Expansion
The two companies have completed an initial feasibility study for the L.A. LIVE site. This assessment evaluated land-use requirements, airspace integration, power availability, and community impact. The project has now advanced to a secondary phase focused on operational procedures and passenger experience.
To support flight operations, the facility will incorporate electric aviation chargers manufactured by BETA Technologies. This hardware integration aligns with the Advanced Air Mobility (AAM) industry’s ACES consortium, which aims to standardize charging infrastructure across different eVTOL platforms.
The downtown location will connect to a broader regional network. According to reporting by Aviation International News, Archer’s Los Angeles architecture includes a central operational hub at the newly acquired Hawthorne Municipal Airport (KHHR). Additional planned nodes include Los Angeles International Airport (KLAX), Hollywood Burbank Airport (KBUR), John Wayne Airport (KSNA), SoFi Stadium, and the University of Southern California. Pollstar News reports that passenger travel times across this network are estimated between 10 and 20 minutes.
Aligning with the LA28 Games
The vertiport development is closely tied to the upcoming LA28 Olympic and Paralympic Games. The Downtown Los Angeles Zone is scheduled to host 18 Olympic and Paralympic sports, positioning L.A. LIVE adjacent to Crypto.com Arena and the Los Angeles Convention Center as a high-traffic transit corridor. Archer previously secured the designation of Official Air Taxi Provider for the LA28 Games and Team USA.
Archer Founder and CEO Adam Goldstein highlighted the strategic timing of the infrastructure build.
“Working with AEG on an iconic project like this vertiport at L.A.
