The Space Force added two new companies to its stable of launchers on July 8, bringing the military’s launch acquisition program to seven companies.

What: The National Security Space Launch program allows the military to block buy launches to get defense payloads to orbit, both giving the Pentagon assured access to space and promoting competition in the industry by pre-ordering rides to space from multiple providers. A different form of the program dates back to the ‘90s, though the NSSL in its current iteration and name came to be in 2019. 

The process: The Pentagon onboards companies into the launch program and awards IDIQ contracts for missions to be launched over a set time period. That makes pre-vetted companies eligible to compete for task orders to launch specific missions. 

The Pentagon is expected to award 84 missions between FY25 and FY29 as part of the third phase of the program, which is broken into two pieces:

  • Lane 1 is intended to bring new launchers in the door, and handles missions where the department can tolerate more risk. These are awarded to companies with a credible pathway to launch.
  • Lane 2 is for established launchers to fly the military’s most demanding, critical payloads. These are companies with certified, more reliable rockets. 

Rolodex: The Pentagon now has seven companies that can compete for missions across the two lanes.

Companies eligible for Lane 1 include:

  • Blue Origin
  • Impulse Space
  • Relativity Space
  • Rocket Lab
  • SpaceX
  • Stoke Space
  • ULA

Companies eligible for Lane 2 are:

  • Blue Origin
  • SpaceX
  • ULA
