SKY Perfect JSAT Selects SpaceX for Next-Generation Satellite Launches

SKY Perfect JSAT Holdings Inc. announced today that it has finalized an agreement with SpaceX to launch two of its upcoming communications satellites, JSAT-31 and JSAT-32. According to the company, these missions will commence sequentially starting in 2027, joining the previously contracted Superbird-9 satellite to complete a significant modernization of the operator’s orbital fleet.

The selection of SpaceX reinforces a long-standing partnership between the Tokyo-based operator and the launch provider. The new agreement aims to bolster SKY Perfect JSAT’s capacity to handle increasing demands for mobility connectivity, specifically in the aviation and maritime sectors, and to support national security initiatives. By deploying these satellites, the company states it will effectively double the total communications capacity currently provided by its existing fleet of 17 geostationary satellites.

Fleet Modernization and Technical Capabilities

The upcoming launches represent a strategic shift toward fully digitalized and flexible satellite architectures. According to the press release, both JSAT-31 and Superbird-9 are equipped with digital communications payloads that allow for dynamic adjustments of coverage areas and transmission capacity while in orbit. This flexibility allows the operator to redirect resources to meet changing customer needs over a service life projected to exceed 15 years.

In a statement regarding the capability upgrades, Eiichi Yonekura, Representative Director, President & Chief Executive Officer of SKY Perfect JSAT, highlighted the impact of the new hardware:

“The introduction of ‘JSAT-32’ will significantly enhance Ka-band capacity. This will double the total communications capacity currently provided by our fleet of 17 geostationary satellites, strengthening our ability to respond to growing mobility demands, including in-flight connectivity and National Security Field, and delivering more effective and efficient multi-band communication services to our customers.”

Satellite Specifications

The official release details the specific roles and technical foundations of the three satellites scheduled for launch:

• JSAT-31: Built on the Thales Alenia Space “Space INSPIRE” platform, this satellite is scheduled for a 2028 launch. It will provide Ku and Ka-band coverage across Japan, Southeast Asia, Australia, New Zealand, and the Pacific Islands. Its fully digital payload enables in-orbit reconfiguration.
• JSAT-32: Utilizing the Thales Alenia Space “Spacebus 4000 B2” platform, this satellite targets a 2027 launch. It is designed to significantly expand Ka-band capacity primarily for Japan, supporting high-speed connectivity demands.
• Superbird-9: Based on the Airbus Defence and Space “OneSat” platform, this satellite is also scheduled for launch in 2027. It will cover Japan and Eastern Asia with fully flexible Ku and Ka-band capabilities.

Strategic Partnership with SpaceX

SKY Perfect JSAT cited SpaceX’s “proven track record of frequent and reliable launches” as a primary factor in the selection. The two companies have collaborated on multiple missions over the last decade, including the launches of JCSAT-2B and JSAT-144C in 2016, and JCSAT-1C in 2019. The operator noted that these past collaborations have helped drive market transformation, a trend they intend to continue with the upcoming deployment of their next-generation assets.

AirPro News Analysis

The explicit mention of the “National Security Field” in SKY Perfect JSAT’s announcement reflects a broader trend in the Japanese space sector. As geopolitical tensions in the Asia-Pacific region evolve, commercial operators are increasingly aligning their capabilities with government defense needs. The shift toward “flexible” satellites, which can reshape their coverage beams in real-time, offers dual-use advantages, allowing operators to rapidly support emergency communications or secure operations in response to natural disasters or security incidents.

Furthermore, the aggressive expansion of Ka-band capacity with JSAT-32 signals a direct response to the surging market for In-Flight Connectivity (IFC). Airlines are under increasing pressure to provide “home-like” Wi-Fi speeds to passengers, requiring the high throughput that Ka-band satellites provide. By doubling their fleet’s total capacity, SKY Perfect JSAT is positioning itself to capture a larger share of this high-yield mobility market.

Frequently Asked Questions

When will the new satellites launch?
According to the press release, launches are scheduled to begin sequentially in 2027. JSAT-32 and Superbird-9 are targeted for 2027, while JSAT-31 is scheduled for 2028.

What is a “fully flexible” satellite?
Satellites like JSAT-31 and Superbird-9 utilize digital payloads that allow operators to change coverage areas and power allocation while the satellite is in orbit. This contrasts with traditional satellites, which have fixed beams that cannot be altered once launched.

Who are the manufacturers of these satellites?
JSAT-31 and JSAT-32 are manufactured by Thales Alenia Space, while Superbird-9 is manufactured by Airbus Defence and Space.
