The Nike-Cajun was a two-stage sounding rocket built by combining a Nike base stage with a Cajun upper stage.
It retained the external size, shape and configuration of the Deacon but had 36 percent greater impulse than the Deacon due to improved propellant.
[2] It was launched 714 times between 1956 and 1976 and was the most frequently used sounding rocket of the western world.
The Nike Cajun had a launch weight of 698 kg (1538 lb), a payload of 23 kg (51 lb), a launch thrust of 246 kN (55,300 lbf) and a maximum altitude of 120 km (394,000 ft).
The Nike-Cajun configuration was also used by one variation of the MQR-13 BMTS target rocket.
