$187 million commercial contract for initial phase of Tomorrow.io’s planned global satellite constellation

York Space Systems, a leading, US-based national defense and commercial prime providing a comprehensive suite of mission-enabling solutions, will serve as prime contractor for the initial phase of DeepSky, Tomorrow.io’s next-generation early warning constellation, delivering dozens of satellites on York’s flight-proven M-CLASS platform. The $187 million contract, previously disclosed in March, covers the initial phase of the planned proliferated low-Earth orbit constellation.

DeepSky will operate as a proliferated network of multi-instrument spacecraft, designed to close long lasting global gaps in atmospheric and oceanic measurements. York’s M-CLASS platform is uniquely suited to accommodate the full instrument suite Tomorrow.io is employing for DeepSky, with the size, power, onboard processing and thermal management to run active sensors including precipitation radar over every part of the globe, day and night. As prime contractor, York owns end-to-end program delivery for the initial phase, giving Tomorrow.io a single accountable partner from spacecraft manufacture through payload integration.

“DeepSky is one of the most technically ambitious commercial Earth observation programs being built today, and it is filling a measurement gap that has left most of the planet under-observed for decades,” said Michael Laczjok, CTO of York. “Tomorrow.io is taking a technology-forward approach to weather intelligence, from AI-driven forecasting through to a purpose-built active-sensing constellation. The M-CLASS platform was engineered for exactly this class of mission, and DeepSky is a program where its full capability comes to bear.”

Each spacecraft will carry five Tomorrow.io instruments spanning Gen-2 microwave sounders, GNSS radio occultation, GNSS reflectometry, infrared and visible imaging, and precipitation radar from space, together giving national meteorological services and commercial users a full vertical picture of the atmosphere at global refresh rates.

“Deploying a constellation like DeepSky requires a strong, innovative prime partner that can not only move fast on rapid timelines, but also deliver best in class platforms for very demanding payloads and mission configuration,” said Shimon Elkabetz, CEO and co-founder of Tomorrow.io. “York brings that capability, backed by the flight-proven M-CLASS platform and the production track record to develop and deploy DeepSky on the timeline the world needs.”

York’s selection for DeepSky highlights continued expansion into commercial adjacent markets, leveraging the spacecraft prime heritage the company has built across national security and commercial programs. York has invested more than $755 million in production to deliver constellations at this scale and cadence.
