Export restricted (ITAR), sale only to US Citizens and Organizations. Large rocket nozzle built for the upper stage of the LGM-30 Minuteman Intercontinental Ballistic Missile (ICBM) by the Hercules Powder Company, measuring approximately 17.5˝ tall and 16˝ in diameter across the nozzle, with a Hercules label on the side: "Nozzle, Exhaust, Rocket Motor…Stock No. 13268665611, Serial No. NAA0053…Nozzle Position 4." This nozzle was removed from a Minuteman I third stage in conjunction with stage upgrade/conversion to Minuteman II/III (retrofit resulted in a single larger expansion ratio nozzle replacing the original four smaller nozzles).
The LGM-30 Minuteman is an intercontinental ballistic missile (ICBM) developed by the United States during the Cold War and represents the land leg of the U.S. nuclear triad. First deployed in the 1960s, it was designed as a land-based nuclear deterrent, capable of delivering a thermonuclear warhead across vast distances with high accuracy. The Minuteman system, known for its rapid response capability and solid-fuel propulsion, has undergone several upgrades over the decades, making it a cornerstone of the U.S. strategic nuclear forces. The current version, the Minuteman III, remains operational, ensuring the United States maintains a credible and reliable nuclear deterrent.
