Ibadan, 18 September 2026. – Japanese synthetic-aperture radar (SAR) satellite operator Synspective has signed a launch service agreement with Mitsubishi Heavy Industries (MHI) for two StriX satellites, securing a launch aboard Japan’s H3 rocket in the second half of 2027 as it expands its commercial Earth-observation constellation.
The satellites will launch aboard the H3-22L from the JAXA Tanegashima Space Center and will be deployed into a mid-inclination orbit selected to support high-frequency observations of major economic centers and disaster-prone regions worldwide, including the Asia-Pacific.
H3 adds a new launch option for Synspective
The agreement adds a new dimension to Synspective’s launch strategy. Rocket Lab has been the sole launch provider for Synspective’s constellation since 2020, with the company’s StriX satellites continuing to launch on Electron from New Zealand. The H3 agreement introduces Japan’s domestic launch vehicle as an additional route to orbit, giving Synspective another launch option as it expands its constellation.
Synspective described the agreement as a step toward greater “strategic autonomy” in access to space, with the domestic launch option providing a transportation foundation for the rapid expansion of its constellation. The company also linked reliable and continuous satellite deployment to its goal of making SAR data an operational asset for disaster response, infrastructure monitoring and security.
“For SAR data to become an operational, dependable asset in disaster response, infrastructure monitoring, and security, satellites must be delivered into orbit continuously and reliably,” remarked Takashi Nakamura, Executive Officer, Synspective. “This agreement with Mitsubishi Heavy Industries provides that foundation, and I see it as a meaningful undertaking where Japan’s space transportation capabilities and our mission converge. We will continue to steadily advance the establishment of a global Earth observation infrastructure.”
Synspective’s agreement with MHI also follows a similar deal with Japanese lunar exploration company ispace. In July, ispace signed a launch and transportation services contract with MHI for its Mission 3 ULTRA lunar lander, which is scheduled to launch aboard an H3 rocket in 2028. Both agreements demonstrate H3’s expanding role as a domestic launch option for Japan’s commercial space sector, from lunar transportation to satellite-based Earth observation.
A new constellation for sharing small SAR satellite constellation capacity
The H3 agreement comes as Synspective expands its constellation strategy beyond the existing StriX program. On September 15, the company announced Synspective OMNIA, a new program designed to share the capabilities of a small SAR satellite constellation among multiple users.
Under the model, customers can secure priority observation and data-acquisition rights for specific regions and orbital paths without making the large investment required to build and operate an independent satellite system. The model is intended to address the cost and utilization challenges associated with dedicated satellite systems. By pooling demand across multiple users, OMNIA is designed to support higher-frequency observations and greater redundancy while allowing customers to purchase additional shared capacity when needed.
OMNIA will involve the construction of a new, dedicated constellation alongside Synspective’s existing StriX constellation. This combination will increase observation frequency, redundancy and regional coverage while enabling more flexible priority access for customers. The program will also combine satellite constellation capacity with Synspective’s SAR data-analysis capabilities, extending the service beyond access to SAR data to the delivery of information intended to support operational decision-making.
“We believe that in the years ahead, as the world faces many different risks, information from space should be used widely around the world. Synspective OMNIA is a system that lets countries and companies use space while keeping their own information sovereignty, and it is a concrete step toward that goal,” explained Motoyuki Arai, CEO of Synspective Inc.
“By expanding our operations with a new constellation, we will build, together with partners, a system that can observe the whole globe, something no single country or organization could do on its own. The name OMNIA, which we gave this program, reflects our wish to share all of our observation capabilities so that anyone can see and understand any place with their own eyes. It shows our strong commitment to our mission of building new infrastructure for the next generation.”
The H3 agreement therefore comes at a significant point in Synspective’s expansion, as the company moves to diversify its access to orbit while building out the satellite infrastructure needed for a broader commercial Earth-observation service.

Executive Summary
Synspective has secured a launch service agreement with Mitsubishi Heavy Industries (MHI) for two StriX satellites, scheduled to launch aboard Japan’s H3 rocket in the second half of 2027. These satellites will be deployed into a mid-inclination orbit intended for high-frequency observations of economic centers and disaster-prone regions globally, including the Asia-Pacific. This agreement provides Synspective with an alternative launch route to orbit, supplementing their existing service provided by Rocket Lab.
This arrangement is part of Synspective's strategy to achieve greater "strategic autonomy" in accessing space. The partnership aims to establish a foundation for delivering reliable and continuous satellite deployment necessary for using Synthetic Aperture Radar (SAR) data as an operational asset for disaster response, infrastructure monitoring, and security.
Furthermore, the H3 agreement mirrors a similar deal with ispace regarding lunar transportation, demonstrating Japan's expanding role as a domestic launch option across commercial space sectors, from Earth observation to lunar exploration. Concurrently, Synspective is developing the OMNIA program, a new constellation designed to share small SAR satellite capacity among multiple users, aiming to reduce the investment burden for others while increasing the frequency and redundancy of global observations and integrating data analysis capabilities.
Full Take
The convergence of Synspective’s operational goals—achieving data reliability and expanding service reach—with Japan's domestic launch infrastructure (H3) reveals a strategic pattern aimed at mitigating dependence on external providers for critical space access. The establishment of the H3 pathway functions as a structural enabler, not merely a logistical convenience, linking Earth observation and lunar transport capabilities under one national framework. This simultaneous development suggests a focus on creating integrated, sovereign space infrastructure rather than fragmented commercial ventures.
The OMNIA initiative reflects a shift from proprietary asset control to shared utility for achieving broader observational goals. The creation of a shared constellation addresses the economic friction points associated with dedicated satellite systems by operationalizing redundancy and increasing data availability through pooled demand. This signals an understanding that the value of future space systems lies less in individual orbital access and more in networked informational capacity.
The underlying pattern involves leveraging national technological assets to support commercial expansion, positioning these expansions as prerequisites for achieving systemic goals like global monitoring and data sovereignty. The narrative suggests a trajectory where strategic autonomy is built incrementally by intertwining commercial deployment with domestic launch capabilities. The core tension lies in balancing the desire for open, shared access (OMNIA) with the imperative of securing reliable, continuous delivery necessary for high-stakes applications like disaster response, which demands both operational resilience and clear lines of responsibility.
Bridge Questions: If national launch vehicles continue to expand their role in commercial services, how will the international governance structures adapt to managing multi-national constellations operating under shared infrastructure? What are the long-term externalities of pooling observational capacity versus maintaining proprietary data streams for sensitive regions? What mechanisms ensure that the pursuit of shared access does not compromise the operational security or sovereignty of the end-users benefiting from the SAR data?
