Some later reports say the primary payload was a U.S. Navy ELINT / Sigint satellite in the Advanced Jumpseat series.

Secondary payloads contained in or attached to Get Away Special (GAS)hardware in the cargo bay included the Orbital Debris Radar Calibration Spheres (ODERACS) the combined Shuttle Glow Experiment/Cryogenic Heat Pipe Experiment (GCP).

Middeck experiments included Microcapsules in Space (MIS-l); Space Tissue Loss (STL); Visual Function Tester (VFT-2); Cosmic Radiation Effects and Activation Monitor (CREAM); Radiation Monitoring Equipment (RME-III); Fluid Acquisition and Resupply Experiment (FARE); Hand-held, Earth-oriented, Real-time, Cooperative, User-friendly, Location-targeting and Environmental System (HERCULES); Battlefield Laser Acquisition Sensor Test (BLAST); and the Cloud Logic to Optimize Use of Defense Systems (CLOUDS).
