TheDelta 0100 series, alsoDelta 100,0300 or300 series, was an Americanexpendable launch system which conductedorbital launches between 1968 and 1972. It was a member of theDelta family of rockets, and the first to be designated using afour digit numerical code. Two variants were flown, individually designated Delta 0300 and Delta 0900.
TheLong Tank Thor, a stretched version of theThor missile, was used as the first stage of the Delta 0100 series.Castor-2solid rocket boosters were attached to increase thrust at lift-off, three on the 0300 variant, and nine on the 0900. The second stage was aDelta F.
Five 0100 series rockets were launched, three using the 0300 configuration, and two in the 0900 configuration. All launches occurred fromSpace Launch Complex 2W atVandenberg AFB. There was one failure, the launch of ITOS E on July 16, 1973. A hydraulic pump malfunction led to loss of pressure to the second stage attitude control thrusters, causing the launch vehicle to tumble out of control and break up in the atmosphere.
The JapaneseN-I launch vehicle was derived from the Delta 0300, using a Japanese LE-3 engine on the second stage.[1][2]
