April 6, 2026
On April 6, Stevens Aerospace and Defense Systems released major news for King Air operators, announcing the completion of its Supplemental Type Certificate (STC) for the Gogo Galileo HDX high-speed internet system.
Developed in partnership with Gogo and Metrea Aerospace Design, this new certification brings true global, high-speed connectivity to Beechcraft King Air 200 and Beechcraft King Air 300 series aircraft—something that, until now, has largely been reserved for higher-end jet platforms.
Breaking Ground in Global Connectivity
The Gogo Galileo HDX system is powered by Eutelsat-OneWeb’s Low-Earth-Orbit (LEO) satellite network, delivering impressive performance capabilities:
- Up to 60 Mbps download speeds
- Up to 11 Mbps upload speeds
- Reliable, global coverage—including remote regions and over-water routes
One of the most notable advancements is the ability to access high-speed connectivity even while the aircraft is on the ground, eliminating the limitations of traditional air-to-ground systems.
During testing, Stevens reported seamless performance under heavy cabin demand, with multiple users streaming and operating bandwidth-intensive applications simultaneously—without buffering or interruptions.

More Than Just Internet
Beyond raw speed, the Galileo HDX system integrates with Gogo’s AVANCE platform, unlocking a modern connected cabin experience:
- Real-time 3D moving maps
- Onboard entertainment through Gogo Vision
- Streaming to personal devices without relying entirely on external bandwidth
- Built-in cybersecurity and privacy protections
For operators already equipped with AVANCE, the system can be added with minimal aircraft downtime, making it a practical upgrade for aircraft operating beyond North American coverage areas.
Designed for Ease of Installation and Use
Stevens’ STC package was built with operators in mind, offering:
- Integrated Wi-Fi activation
- Streamlined installation process
- Reduced installation costs
The STC currently applies to a range of avionics configurations within the King Air 200 and 300 series. International validations, including EASA and TCCA, are already in progress, expanding accessibility for global operators.
Operators can choose to have the system installed at Stevens facilities or work through authorized Gogo dealers using the STC.
What This Means for King Air Operators
This April 6 announcement represents more than just a new upgrade—it signals a shift in expectations for turboprop connectivity.
King Air operators can now realistically expect:
- Global, uninterrupted internet access
- Connectivity performance approaching that of business jets
- Improved passenger experience for both productivity and entertainment
- Greater operational flexibility for international and remote missions
As inflight connectivity continues to evolve from a luxury to a necessity, solutions like Galileo HDX are helping ensure the King Air platform remains competitive, capable, and future-ready.
Final Thoughts
With this latest STC, Stevens Aerospace and its partners are helping close the connectivity gap between turboprops and jets. The April 6 release marks a meaningful milestone—not just for technology, but for how King Air operators can work, communicate, and stay connected anywhere in the world.
For owners and operators considering upgrades, this is one development that’s worth serious attention.
