Stoke Space, the innovative aerospace startup, has announced a $510 million Series D funding round, underlining the increasingly pivotal role of defense contracts in shaping the future of U.S. space launches[1]. The investment, led by Thomas Tull’s US Innovative Technology Fund (USIT) and bolstered by a $100 million debt facility from Silicon Valley Bank, brings the company’s total capital raised to nearly $1 billion[1]. The round also saw participation from a mix of new and existing investors, including Washington Harbour Partners LP, General Innovation Capital Partners, and notable backers such as 776, Breakthrough Energy, and Toyota Ventures[1].

This new capital infusion is a clear signal of investor confidence in Stoke’s vision—a vision that has been significantly validated by a recent National Security Space Launch (NSSL) contract from the U.S. Space Force[1]. The NSSL program, a cornerstone of U.S. defense strategy, ensures reliable and frequent access to space for national security payloads. Stoke’s contract win highlights how defense requirements are driving both technological innovation and business growth in the private space sector, as the U.S. seeks to maintain its edge in a rapidly evolving global space economy[1].

At the heart of Stoke’s strategy is the Nova launch vehicle, a fully and rapidly reusable rocket designed to provide high-frequency, cost-effective access to orbit[1][2]. Unlike many of its peers, Stoke is prioritizing scalable manufacturing and operational readiness, with plans to activate Launch Complex 14 at Cape Canaveral and build the necessary infrastructure for high-cadence launch operations[2]. This approach is not only critical for meeting the demands of commercial satellite operators but also aligns perfectly with the rigorous, mission-critical requirements of defense customers[2].

The global space economy reached $613 billion in 2024, with commercial activity accounting for the lion’s share of growth[2]. Yet, the sector’s trajectory is increasingly shaped by defense needs, as nations and alliances vie for strategic advantage in Earth orbit and beyond. Medium-lift launch capacity—Stoke’s sweet spot—is projected to grow at a 14.6% compound annual rate through 2035, reflecting surging demand for affordable, reliable orbital access from both government and commercial customers[2].
