York Space Systems has closed its acquisition of ALL.SPACE, a roughly $300 million deal that folds the satellite-terminal maker in as a wholly owned subsidiary of the defense space prime.
The purchase is York's third since it went public in January 2026, and the pattern is getting hard to miss. Propulsion, then space solar, now terminals. A satellite builder that IPO'd six months ago is assembling a full-stack defense space prime one supplier at a time.
York Space Systems closed the ALL.SPACE deal for $155 million cash and the balance in stock
York Space Systems paid $155 million in cash for ALL.SPACE and covered the rest of the roughly $300 million price with 5.9 million of its own shares. That structure matters more than the headline number. A company that went public in January and is buying suppliers with its own equity by July is telling the market it would rather spend stock than cash on the stack it is building.
The deal is the third consolidation since the January 2026 initial public offering, after propulsion provider Orbion Space Technology and space solar developer Solestial. The ALL.SPACE terms were first outlined in May 2026, and closing them now hands York a terminal portfolio to sit alongside its buses, propulsion, and power.
The Hydra terminal solves the connection problem a proliferated constellation creates
ALL.SPACE's Hydra terminal is the reason York wanted the company. It is a multi-link, software-defined ground terminal built to hold connectivity across Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geostationary Earth Orbit (GEO), and High Elliptical Orbit (HEO) at once, across multiple frequency bands, and to keep the link alive for platforms on the move in jammed, GPS-denied environments.
Here is the mechanism York is buying into. A proliferated constellation is only worth the bandwidth it actually delivers to the edge. You can orbit thousands of satellites, but a moving vehicle or an uncrewed system still needs a terminal that can hop between orbits without dropping the link and without leaning on GPS to find the sky. The satellite is the supply. The terminal is the last mile. York builds the supply at rate. ALL.SPACE built the last mile.

The Proliferated Warfighter Space Architecture is the customer both halves are built for
The combined hardware is aimed squarely at the U.S. Department of Defense's Proliferated Warfighter Space Architecture (PWSA), the program betting that a large, dispersed low-orbit fleet survives what a handful of exquisite satellites cannot. Pair automated tracking terminals with high-rate satellite manufacturing and the pitch to a program office writes itself: resilient tracking for unmanned systems operating at scale across contested theaters, from one vendor rather than five.
ALL.SPACE, now the terminal division, is still ramping deliveries from a newly established U.S. base. The domestic footprint is not incidental. For a defense customer, where the terminal is built is part of what it is buying.
York is buying the pieces of a single-source PWSA prime with equity while the stock is fresh, and Orbion, Solestial, and ALL.SPACE together cover propulsion, power, and the terminal a program office would otherwise have to stitch together itself. The wrinkle is that York is running this rollup while ongoing investigations into its historical defense software disclosures play out, and a prime consolidating the whole stack draws more scrutiny, not less. Expect at least one more vertical integration before the year is out. Expect the diligence on the next one to run longer than it did on this.
