Sunnyvale, California

Description

The Polaris A1 was a solid-fuel ballistic missile that a submerged submarine could launch, and Lockheed was the prime contractor. The photograph shows a Polaris A1 and a later Polaris A3 at a museum in Honolulu.

Importance

Lockheed moved its missile division to Sunnyvale in 1956, next to Moffett Field. By the early 1960s, Polaris and secret satellite programs made the Sunnyvale division one of the largest employers in the Valley. The former Joshua Hendy plant in Sunnyvale, then a part of Westinghouse, made launch equipment for the missile.

Interesting fact

On September 24, 1958, the first Polaris test missile did not turn onto its correct path because of a programming error, and it exploded.
