Design and development

The Terrier-ASROC-Cajun ("Terasca") rocket was developed during early 1959 by the Naval Ordnance Test Station, located at China Lake, California, to fill a U.S. Navy requirement for a three-stage sounding rocket, intended to launch experimental payloads for conducting high-altitude research. The rocket utilised a combination of existing missiles in its construction; the first stage was a Terrier surface-to-air missile; an ASROC anti-submarine rocket made up the second stage, while a Cajun sounding rocket was utilised as a third stage. The Terrier first stage produced thrust, while the ASROC second stage provided , and the third-stage Cajun motor had a thrust rated at . The theoretical apogee for Terasca was ; it could carry a scientific payload of up to .

Operational history

Three launch attempts of the Terasca missile were made from the launch facility at Vandenberg Air Force Base during 1959, utilising the Western Launch and Test Range. The first launch attempt took place on May 1; this launch was a failure. A second launch attempt on June 26, however, was successful, with the rocket reaching an apogee of . A third launch, attempted on August 12, however, was also a failure; following the third launch, the Terasca program came to a close.
