The Thor-Burner was an American expendable launch system, a member of the Thor rocket family. It consisted of a Thor missile, with one or two Burner upper stages. It was used between 1965 and 1976 to orbit a number of satellites, most commonly Defense Meteorological Satellite Program weather satellites. Twenty-four were launched, of which two failed. Each launch cost 11.890 million 1985 US Dollars. It weighed 51,810 kg and was 24 metres tall.
Burner 1 and Altair
The Burner 1 stage was an Altair rocket stage as used for the third stage of some Vanguard launch vehicles, but equipped by Boeing with 3-axis control.[1]
This combination was used for six vehicles. The first was launched 1965-01-18 and the sixth 1966-03-30. These were early launches of classified Defense Meteorological Satellite Program satellites. One of these launches failed.[2]
Burner 2
The Burner 2 used with the Thor-Burner was the first solid fuel upper-stage vehicle used for general space applications that had full control and guidance capability. The first Burner II flight was on 1966-09-15.[3]
