All-Civilian US Workforce Completes Historic Overhaul of 15,000-Mph Nuclear Missile

An all-civilian Air Force squadron has completed a rare and historic overhaul of a Minuteman III intercontinental ballistic missile component, removing a massive suspension system from a North Dakota launch facility, transporting it to California for refurbishment, and returning it to its silo. The successful operation marks a significant milestone in sustaining America's aging nuclear arsenal.

MINOT AIR FORCE BASE, N.D. – In a first-of-its-kind operation, the 583rd Missile Maintenance Squadron – an all-civilian unit with no active-duty service members – completed a full overhaul of a Minuteman III missile suspension system on August 18, 2026, near Minot Air Force Base, North Dakota .

The suspension system, which plays a crucial role inside a Minuteman III launch facility by supporting the missile and maintaining the structure around it within the silo, was removed from an underground launch facility earlier this year . Technicians then transported the massive assembly to Vandenberg Space Force Base in California for depot-level work before returning it to Minot for reinstallation .

"The suspension system that was removed from one of the launch facilities earlier this year was the first operation site at Minot AFB to be removed, transported to Vandenberg Space Force Base, California, refurbished and returned to be reinstalled," said Roy Ring, production superintendent for the 583rd Missile Maintenance Squadron .

A Rare and Logistical Challenge

Technicians normally handle preventative maintenance at the launch facility itself. A complete overhaul, which requires removing the entire assembly and transporting it across the country, rarely occurs across the Minuteman III fleet .

"The complete overhaul of a suspension system does not happen often across the Minuteman III fleet," Ring said .

The operation created a significant logistical challenge. The team had to remove the component from an active launch facility, transport it safely to California, complete the refurbishment work, and prepare it for its return to the operational site . The successful round trip marks the first such operation at Minot Air Force Base .

The All-Civilian 583rd Missile Maintenance Squadron

The 583rd Missile Maintenance Squadron occupies an unusual position within the Air Force's nuclear mission. It has no active-duty personnel and relies entirely on civilian employees .

"We are an all-civilian workforce," said KyAnn Betz, the squadron's director. "We have 196 employees at five geographically separate units across five bases: Minot AFB, Malmstrom AFB, F.E. Warren AFB, Vandenberg SFB and Hill AFB" .

The squadron brings more than 250 combined years of Minuteman III experience at each base where it operates . It is the only squadron in the Department of War authorized to perform depot-level maintenance in underground and above-ground Minuteman III facilities .

The squadron traces its roots back to the mid-1980s, when it was created as "Rivet Mile" – short for Minuteman Integrated Life Extension – to support the Minuteman III's service-life program . Today, the unit continues that mission, inspecting and repairing suspension systems across the fleet .

Sustaining an Aging Arsenal

The Minuteman III has been the backbone of America's land-based nuclear deterrent since 1971, with roughly 400 missiles still deployed at bases in North Dakota, Montana, and Wyoming . Keeping that infrastructure operational requires more than maintaining the missiles themselves – supporting systems inside launch facilities also need inspection, repair, and occasional major refurbishment .

The Minot project demonstrated that a complete suspension-system overhaul can happen away from the launch site, establishing a repeatable path for moving large components through the depot-maintenance process . This capability could prove valuable as the Minuteman III fleet continues to age and require increasingly complex maintenance.
