Summary

The U.S. Space Force has expanded its National Security Space Launch (NSSL) Phase 3 Lane 1 contract vehicle, adding Relativity Space and Impulse Space to the roster of commercial providers eligible for future task orders. This move, announced July 7, aims to diversify how military satellites reach orbit and inject more commercial competition into lower-risk national security missions. Relativity Space is developing the medium-lift Terran R rocket, intended for missions that do not require the highest levels of mission assurance, despite not yet having its first flight. Impulse Space, conversely, focuses on orbital transfer vehicles, or "space tugs," and high-energy kick stages, rather than full launch vehicles. Its inclusion signifies an an evolution in the Space Force's approach, considering integrated transportation services where different companies provide launch and final orbital delivery. This Lane 1 procurement track provides a pathway for newer providers to enter the Pentagon's launch business, distinct from Lane 2, which is reserved for the military's most demanding missions requiring fully certified systems.

Key takeaway

For defense contractors and space industry strategists evaluating future opportunities in national security space, you should recognize the Space Force's shift towards broader commercial integration. This includes not just traditional launch vehicles but also specialized orbital transportation services like those offered by Impulse Space. Prepare for increased competition and evolving procurement models that favor demonstrated flight capability for Lane 1 missions, distinct from the stringent requirements of Lane 2.

Key insights

The Space Force is diversifying national security launches by integrating new commercial providers and evolving its definition of launch services.

Principles

• Diversify launch providers for national security missions.
• Integrate commercial innovation for lower-risk space operations.
• Define launch services broadly to include orbital transportation.

Method

Space Force uses an Indefinite Delivery, Indefinite Quantity (IDIQ) contract vehicle (NSSL Phase 3 Lane 1) to pre-qualify commercial providers for lower-risk national security launch task orders.

In practice

• Relativity Space offers medium-lift Terran R for less stringent missions.
• Impulse Space provides orbital transfer vehicles for final delivery.
• Consider integrated launch and orbital delivery services.
