The NROL-36 mission will be launched for the National Reconnaissance Office in support of national defense. In addition to the NROL-36 mission, the launch also will deliver 11 smaller auxilary payloads or "cubesats" to space.

The cubesats were developed under the sponsorship of the NRO and NSA by the Space and Missile Command, the Aerospace Corporatio, University of Southern California, University of Colorado, Cal Poly, Morehead State University, University of California-Berkley and the Lawrence Livermore National Lab. The cubesat missions will study space weather and communication, space environment, debris mitigation, maritime shipping container tracking and spaceflight safety and orbit refinement.
