This is part of the inertial guidance system of a U.S. Navy Poseidon C-3 submarine-launched ballistic missile (SLBM). Designed by the MIT Instrumentation Laboratory, it used a set of gyroscopes and accelerometers to measure the missile's velocity and position.

Developed by Lockheed, Poseidon C-3s were two-stage, solid-fuel missiles with a range of approximately 5300 km (3,300 miles). Deployed from 1971 to the early 1990s, sixteen missiles were carried on a submarine, with each missile having up to 16 independently-targetable nuclear warheads.

This specimen was made from spare parts and donated by the U.S. Navy to the Museum in 1973.
