The Sperry Gyroscope Company was founded in 1910 by Elmer A. Sperry, a noted engineer and inventor who patented the first ballistic marine gyrocompass in 1911. During World War I, Sperry Marine continued in the development of new-generation gyrocompass products and also pioneered the development of gyro fire control and autopilot systems. During World War II, the company grew rapidly in response to the surging demand for marine gyrocompasses for the U.S. and Allied Navies.

Leading supplier of navigation
Following the war, Sperry Marine continued to consolidate its position as the leading supplier of marine gyrocompasses and took the lead in developing integrated bridge systems for the commercial marine and naval markets. During the 1990's, Sperry Marine introduced the first ring laser gyro system for the U.S. Navy and rapidly became the world leader in ring laser gyro technology.
Sperry Marine was formed in 1997 from three well-known brand names in the marine industry: Sperry Marine, Decca and C. Plath. Sperry Marine was acquired by Litton Industries in 1996, followed by the Racal-Decca marine electronics business unit in 1997. They were combined with another Litton company, C. Plath, to create a single integrated worldwide supplier of navigation, communication, information and automation systems for commercial marine and naval markets. In 2001 Sperry Marine became part of the Northrop Grumman Corporation.
