Douglas Aircraft
Thor was the free world's first operational intermediate range ballistic missile (IRBM). It was 65 feet long, 8 feet in diameter and weighed 105,000 pounds. Douglas Aircraft was the prime contractor. The missile utilized a single stage North American Rocketdyne LR-79 liquid oxygen rocket motor, which provided 150,000 lbs of static thrust. This gave the Thor of range of 2,000 miles. Development of the system was rapid. Thor's first successful launch was made on 20 Sep 57 and it entered active military service in September 1958. It was launched from a combination transporter-erector vehicle and was directed to its target by a self-contained inertial guidance system. It was originally designated the SM-75, but later redesignated the PGM-17A. The LR-79 rocket motor was tested extensively at Edwards AFB's Rocket Propulsion Laboratory.| HM Number | HM17VR |
