Array Labs raises $21M from Mitsubishi Electric to scale space radar
What's the deal? Array Labs has raised a $21M strategic funding round led by Japanese conglomerate Mitsubishi ElectricDealroom has a profile for this one. Try Dealroom →, the space-based radar company told Tectonic in an exclusive. The round follows a $20M Series A that closed in January 2026.
What does Array do? Founded out of Y Combinator in 2022, the company builds lower-cost radar satellites that 3D-map the Earth. Roughly suitcase-sized, each satellite carries a radar on one side and a fold-out solar array producing four kilowatts of power on the other.
How it works: The satellites operate in clusters of four or more, capturing radar data from different angles that Array's software stitches into a 3D map. That output currently carries about 30 minutes of latency, which the company is working to cut.
What's the money for? Array will scale its team, expand across the Indo-Pacific with Mitsubishi, and explore new applications for its radars and satellite buses. Mitsubishi will be a "strategic partner of [theirs] in the Asia Pacific region moving forward," founder and chief operating officer Isaac Robledo said.
Why Mitsubishi? The conglomerate works across defense, radars, space, and satellite tech, making it both an investor and a regional gateway. Array is at 50 employees and plans to reach 70 by the end of 2026.
The track record: Array raised a $5M seed post-YC and a $10M pre-Series A in 2024. It launched two test satellites in 2025 and plans further launches in April and October 2027, plus two payload launches in mid-2027.
Government pull: Array has won contracts with the Air Force, Space Force, Navy, Army, SOCOM, and DARPADealroom has a profile for this one. Try Dealroom →, with total contract value in the "eight figures," per a Y Combinator post in January 2026.
The signal: The raise shows the defense tech money tap is still open, and that strategic investors are willing to back radar startups as a route into new regional markets. For Array, the deal marks a sharp step-up from its earlier rounds as it moves from selling imaging data to building the satellites themselves.
