|Launch vehicle.||Atlas-Agena or Titan III-C boosters.|
|Launch site.||N\A in the USA.|
|Ceased operations.||Vela-5B operated until 19 June 1979, although telemetry tracking was poor after mid-1976. The X-ray detectors on Vela 5A failed on 24 July 1970, leading to it's abandonment in 1976.|
|Owner(s).||U.S. Department of Defense and the U.S. Atomic Energy Commission.|
|Is it still in orbit.||Yes.|
|Launch mass.||N\A, but large for it's time and class.|
|Nationality(s).||Mostly American, but with some Dutch technical and manufacturing help. The Dutch also had some usage rights, but most stayed in American hands.|
|Satellite type.||Special reconnaissance satellite made to detect nuclear initiations and detonations in space.|

It was part of a major series of 12 unmanned American reconnaissance satellites developed to detect radiation from nuclear explosions in the Earth’s atmosphere, that were lunched from 1963 to 1970.
