SINS Stable Platform and Housing Assembly

This is one of three inertial guidance units from the USS Alabama. Manufactured by the Autonetics Marine Systems Division of Rockwell International (now Boeing), the SINS was installed on the boat in 1983 and removed in 2006 after over 60 patrols.

Information about the ship’s position, speed, heading, and attitude were constantly transmitted from the SINS to the missile fire-control system. The boat’s exact position was required for launching ballistic missiles.
