Northwood Space closes $375 million Series C for satellite downlink buildout

Northwood Space Corp. closed a $375 million Series C to scale manufacturing of the antennas behind its satellite downlink network, Data Center Dynamics reported. The round takes total fundraising to $511 million. Andreessen Horowitz and DFJ Growth co-led the round, with follow-on investments from Washington Harbour Partners, Alpine Space Ventures, StepStone, In-Q-Tel and others. HSBC Innovation Banking provided a multi-year credit facility for working capital and network expansion.

The company raised a $100 million Series B in January, led by Andreessen Horowitz, around the same time it won a $49.8 million contract with the US Space Force to upgrade its satellite control network. An earlier $30 million round in 2025 followed $6.3 million in seed funding.

Northwood's anchor is the $49.8 million Space Force award, not the hyperscaler or AI-lab leases that set digital infrastructure pricing.

Proceeds will fund the buildout of downlink technology for US government and commercial contracts, delivery of existing commitments and hiring. Northwood opened a 185,000-square-foot headquarters and factory in Torrance, California, in September, increasing its manufacturing footprint fivefold. Its antennas are installed at six sites, and the company has announced Prism and Portal antennas that it says push transmission capacity above 10 Gbps per site.

At full production the company expects to build hundreds of antennas a year, with a site going "from truck arrival to live links in three to four hours" and new sites equipped in three months. Northwood says it controls the full stack, including the choice of where to install antennas at other companies' ground stations to reach their fiber. It hopes to enable sites to deliver 100+ Gbps in high-demand regions by the end of 2027, against the 10 Gbps per site its announced antennas are capable of today.
