Orbiting Vehicle 1-11 (also known as OV1-11) was an American satellite launched on 27 July 1967 to study a range of environmental conditions in the upper atmosphere. Part of the OV1 series of USAF satellites, using standardized designs and sent to orbit on decommissioned Atlas ICBMs to reduce development and launching costs, OV1-12 was launched with two other satellites in the series, OV1-12, and OV1-86, in the first triple launch of the program. The satellite was lost during launch when its onboard propulsion module failed.

Orbiting Vehicle 1–12 (also known as OV1-12) was a satellite launched on 27 July 1967 to measure the radiation hazard posed by solar flares. Part of the OV1 series of USAF satellites, using standardized designs and sent to orbit on decommissioned Atlas ICBMs to reduce development and launching costs, OV1-12 was launched with two other satellites in the series, OV1-11, and OV1-86, in the first triple launch of the program. Only partially successful due to an inability to remain stable in orbit, the satellite reentered the Earth's atmosphere on 22 July 1980.

Orbiting Vehicle 1-86 (also known as OV1-86) was a satellite launched on 27 July 1967 to measure the temperature radiation properties of different types of terrain. Part of the OV1 series of USAF satellites, using standardized designs and sent to orbit on decommissioned Atlas ICBMs to reduce development and launching costs, OV1-86 was launched with two other satellites in the series, OV1-11, and OV1-12, in the first triple launch of the program. It was the only OV1 satellite to be cobbled together from two of its sister satellites, utilizing the unused body on OV1-8 and the unused propulsion module on OV1-6. OV1-86 was only partially successful due to the failure of its Vertistat gravity-gradient stabilization system. The satellite reentered the Earth's atmosphere on 22 February 1972.
