This is a U.S. Navy Poseidon C-3 submarine-launched ballistic missile (SLBM), deployed from 1971 to the early 1990s. Developed by Lockheed as a successor to the first-generation Polaris SLBM, Poseidon C-3s were two-stage, solid-fuel missiles with a range of approximately 5,300 km (3,300 miles).

This Poseidon C-3 was assembled from spare parts by Lockheed and donated by the U.S. Navy to NASM in 1973.
