The PAC 1 (Package Attitude Control) system was carried piggyback on a Delta-N second stage during the August 9, 1969, launch of the OSO 6 satellite. It remained intentionally attached to the Delta stage.

PAC was inserted into orbit (547 × 483 km) to flight test a long-life, low-power, three-axis, earth-stabilized control system for the Delta second stage and to demonstrate the feasibility of using this stage as a platform for experimental payloads.
