USS Somerset (AK-212) was an Alamosa-class cargo ship that was constructed for the US Navy during the closing period of World War II. She was later acquired by the US Army in 1946 and the US Air Force in 1957 before being reacquired by the USN as the USNS Coastal Sentry (T-AGM-15), a missile range instrumentation ship.
