U.S. Space Force Expands NSSL Vendor Pool To More Than Rocket Builders
The U.S. Space Force expanded the NSSL Phase 3 Lane 1 vendor pool to seven companies, adding Impulse Space and Relativity Federal on July 7. Initial providers were SpaceX, Blue Origin, and ULA in June 2024, with Rocket Lab and Stoke Space added in March 2025. Lane 1 supports lower-risk national security launches; SpaceX has most awarded task orders.
How this was made
The 30-second read
Why it matters
The newest incremental fact is that Impulse Space and Relativity Federal were added as potential Phase 3 Lane 1 providers on July 7, expanding the eligible vendor pool to seven. However, the article does not disclose new task order awards, pricing, or timelines beyond general expectations for first flights and a broader plan to award more Lane 1 task orders by end of fiscal 2026.
Market read
For traders, the actionable signal is limited because the article expands eligibility but does not provide new contract award amounts or immediate execution milestones for the newly added providers beyond general first-flight expectations.
What to watch
Execution risk dominates: multiple providers are still awaiting first flights or are grounded due to anomalies, so eligibility alone may not change near-term delivery timelines.
Background
The Space Force’s National Security Space Launch (NSSL) uses a two-prong procurement strategy, with Phase 3 Lane 1 designed to support more risk-tolerant rockets and systems.
Ticker impact
Rocket Lab is added as a Phase 3 Lane 1 provider in March 2025, with expectations to fly its vehicle for the first time within the next year.
Limited near-term impact; any effect is likely incremental and sentiment-driven.
The article confirms Rocket Lab’s Lane 1 onboarding and a near-term first flight expectation, but the newest July 7 additions are Impulse Space and Relativity, not Rocket Lab.
Stoke Space was added to the Phase 3 Lane 1 pool in March 2025 and expects to fly its vehicle for the first time within the next year.
Low immediate impact; watch for follow-on task order announcements.
The text provides onboarding timing and a first-flight expectation, which are relevant, but it does not disclose new July 2026 contract details for Stoke.
Market effects
Expanding NSSL Lane 1 eligibility increases competitive optionality for national security launch providers, but the article emphasizes that awarded missions have largely concentrated at SpaceX so far.
US defense space procurement remains the primary driver, with new entrants based in California highlighted.
Limited direct global read-through because the procurement is US national security launch-focused.
Counterpoint
Lane 1 onboarding may not translate into near-term revenue because the article provides no contract values and notes missions awarded so far have largely gone to SpaceX.
