SES Completes Global Satellite Network with Final O3b mPOWER Launch
The 13-satellite O3b mPOWER constellation will deliver high-speed connectivity to remote and underserved regions by.
SES has completed its O3b mPOWER satellite constellation with the successful launch of the final three spacecraft, a milestone that promises to transform high-speed connectivity for maritime, government, and enterprise users in remote and underserved regions.
The three satellites, designated as the 11th, 12th, and 13th in the O3b mPOWER series, lifted off at 2:49 pm local time on September 13, 2026, aboard a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station.
Why this constellation matters for maritime and remote connectivity: o3b mpower satellites
The O3b mPOWER system is designed to deliver high-performance, low-latency connectivity to users in areas where terrestrial networks are either unavailable or unreliable. This closer proximity reduces latency significantly, making the system ideal for applications requiring real-time data transmission, such as maritime communications, cloud computing, and government operations.
The newly launched satellites will join the 10 O3b mPOWER spacecraft already in operation, forming a 13-satellite constellation capable of providing connectivity ranging from tens of megabits per second to multiple gigabits per second at individual sites. This expanded capacity is expected to benefit a wide range of customers, including shipping companies, offshore energy platforms, remote industrial operations, and telecommunications providers serving regions with limited infrastructure.
Adel Al-Saleh, CEO of SES, highlighted the significance of the launch in a statement:
“This launch marks a defining milestone for SES as we complete the O3b mPOWER constellation and further strengthen our MEO capabilities. More importantly, it reinforces our ability to deliver resilient, secure and scalable connectivity for customers around the world, helping governments, enterprises, cloud providers and mobility customers meet their most critical needs. As customer demands continue to evolve, SES is focused on building smarter, more integrated solutions that bring together the strengths of multiple technologies and orbits to deliver seamless connectivity worldwide.”

The launch was not without its challenges.
What the completed constellation means for global shipping and remote industries
The completion of the O3b mPOWER constellation is particularly significant for the maritime industry, where reliable connectivity is critical for navigation, crew welfare, and operational efficiency.
In addition to maritime applications, the constellation will support a variety of other industries. The system’s flexibility also makes it suitable for remote industrial operations, such as mining, oil and gas exploration, and scientific research in isolated locations.
SES has positioned O3b mPOWER as a key component of its broader strategy to integrate multiple technologies and orbits to deliver seamless connectivity. The company’s approach combines the strengths of MEO satellites with those of geostationary satellites and terrestrial networks, creating a hybrid system that can adapt to the evolving needs of customers across different sectors.
The newly launched satellites are expected to be fully operational by mid-2027, at which point the completed constellation will provide enhanced resiliency, geographic reach, and capacity. This timeline aligns with the growing demand for high-speed connectivity in remote and underserved regions, driven by the expansion of digital services, the proliferation of Internet of Things (IoT) devices, and the increasing reliance on cloud-based applications.
For maritime users, the benefits of the O3b mPOWER system extend beyond improved connectivity. The system’s low latency and high throughput will enable more efficient fleet management, enhanced crew communications, and better support for autonomous and remotely operated vessels. As the maritime industry continues to embrace digitalisation and automation, reliable satellite connectivity will play an increasingly critical role in ensuring the safety, efficiency, and sustainability of global shipping operations.
SES’s investment in the O3b mPOWER constellation reflects a broader trend in the satellite communications industry, where operators are increasingly focusing on delivering high-performance, flexible solutions to meet the needs of diverse customer segments. The completion of the constellation positions SES as a leader in the MEO satellite market, with a proven track record of innovation and a commitment to expanding connectivity worldwide.
As the newly launched satellites undergo testing and integration into the existing network, SES will continue to work with customers to tailor solutions that address their specific connectivity challenges. The company’s focus on building integrated, multi-orbit systems ensures that it remains well-positioned to meet the demands of an increasingly connected world, where reliable, high-speed communications are essential for business, government, and everyday life.
For now, the successful launch of the final three O3b mPOWER satellites marks a significant achievement for SES and a major step forward in the quest to bridge the digital divide. With the constellation now complete, the stage is set for a new era of connectivity that promises to transform industries, empower communities, and drive innovation in some of the world’s most remote and challenging environments.
