This South Dakota missile wing completed the Cold War’s most dangerous weapons transition by 1963

Minuteman Missiles During the Cuban Crisis Era

Deep beneath the South Dakota prairie sits Delta-09, a concrete missile silo that once held a Minuteman II nuclear missile capable of destroying entire cities.

Just miles away, the Delta-01 Launch Control Center still contains the original control consoles where two Air Force officers could have launched ten missiles with the turn of their keys.

These sites at Minuteman Missile National Historic Site tell the story of America’s closest brush with nuclear war and the technological race that defined the Cold War.

In October 1962, as President Kennedy stared down Soviet missiles in Cuba, the first Minuteman missiles went on high alert status. The timing was no coincidence.

On October 24th, 1962, the very day tensions peaked during the Cuban Missile Crisis, America’s first Minuteman field became operational at Malmstrom Air Force Base in Montana.

Meanwhile, crews in South Dakota were rapidly replacing dangerous liquid-fueled Titan missiles with the new solid-fueled Minuteman system, a switch that would prove lifesaving when a Titan missile exploded in Arkansas eighteen years later, killing an airman and destroying its silo.

Here’s how these underground sites witnessed America’s nuclear standoff with the Soviet Union and the deadly serious business of Cold War deterrence.

Spy Planes Caught Soviet Missiles in Cuba

American U-2 spy planes took photos over Cuba on October 14, 1962, that shocked officials. The pictures showed Soviet nuclear missiles being built just 90 miles from Florida.

President Kennedy learned about this two days later during a morning briefing that started the Cuban Missile Crisis. Experts told Kennedy these missiles could hit most American cities within minutes once ready.

Kennedy quickly formed a special team called ExComm to figure out how to handle this threat.

Nuclear Forces Got Ready as Tensions Grew

As the crisis with the Soviets worsened, Strategic Air Command put all U. S.

nuclear weapons on high alert. B-52 bombers loaded with nuclear bombs flew non-stop, ready to strike if needed.

At Malmstrom Air Force Base in Montana, crews readied the first working Minuteman I missiles for possible use. The Navy moved nuclear submarines into position in the Atlantic.

American Jupiter missiles in Turkey, which had worried the Soviets earlier, stood ready as both countries moved closer to war.

The First Minuteman Missile Stood Ready

At 11:16 AM on October 26, 1962, the Alpha-06 launch site at Malmstrom became America’s first Minuteman missile on “strategic alert.” The 341st Strategic Missile Wing’s 10th Squadron brought this new solid-fuel rocket online during the most dangerous days of the crisis.

Unlike older missiles that needed hours of fueling, the Minuteman could launch almost instantly. This three-stage rocket let military commanders hit Soviet targets within minutes of getting orders.

Kennedy Drew a Line in the Ocean

President Kennedy went on TV on October 22, 1962, and told Americans about the missiles and his plan to stop more Soviet weapons from reaching Cuba.

The Navy created a “quarantine” with 180 ships forming a blockade around Cuban waters.

On October 24, Strategic Air Command took control of the first Minuteman flight, putting these missiles on alert two days later.

The world watched nervously as Soviet ships sailed toward the American naval blockade, not knowing if they would stop or try to push through.

More Missiles Joined America’s Nuclear Force

In the four days after the first Minuteman went on alert, crews at Malmstrom turned on four more missiles. By November 10, they had the entire Alpha Flight working, completing America’s first Minuteman squadron.

The solid-fuel design of these new missiles gave military leaders a big advantage over the older Atlas and Titan missiles, which needed hours of dangerous prep before launch.

President Kennedy reportedly called the Minuteman missiles his “Ace in the Hole” during the standoff with Soviet leader Khrushchev.

Workers Rushed to Build New Missile Sites in South Dakota

The Air Force started the 44th Strategic Missile Wing at Ellsworth Air Force Base in South Dakota on January 1, 1962, marking the first Minuteman IB wing.

The base still used the older liquid-fueled Titan I missiles, which the military now saw as outdated.

Construction teams began building 150 new Minuteman silos across the South Dakota prairie while keeping the Titan system running. The workforce from Peter Kiewit Sons’ Company grew to 2,915 people at its peak.

Old Titans Made Way for New Technology

Defense Secretary Robert McNamara announced on May 16, 1964, that the military would speed up getting rid of the first-generation Titan I missiles.

The 850th Strategic Missile Squadron took their Titan missiles off alert status on January 4, 1965.

Workers shipped out the last Titan missile on February 12, 1965, completing South Dakota’s switch to solid-fuel technology. This change removed the dangerous liquid propellants from the state’s nuclear arsenal.

South Dakota’s Nuclear Arsenal Reached Full Power

Crews placed the first Minuteman IB missile in its silo near Wall, South Dakota in April 1963.

By the end of that year, all 150 Minuteman missiles stood ready for action, giving the 44th Strategic Missile Wing its complete nuclear capability.

The Air Force marked another milestone on April 21, 1967, when they put America’s 1,000th Minuteman missile on alert at Malmstrom.

The solid-fuel technology kept missiles ready to launch at a moment’s notice throughout the Cold War.

A Dropped Wrench Started a Nuclear Nightmare

A worker accidentally dropped a nine-pound socket wrench in a Titan II silo in Damascus, Arkansas at 6:30 PM on September 18, 1980.

The socket fell 70 feet before punching a hole in a fuel tank, causing toxic propellant to leak throughout the 374-7 missile complex.

Poisonous fuel vapors filled the silo as emergency crews rushed to evacuate the underground control center.

The damaged Titan II carried a 9-megaton W-53 nuclear warhead, with explosive force 600 times greater than the Hiroshima bomb.

The Explosion Killed an Airman and Threw the Warhead

Senior Airman David Livingston and Sergeant Jeff Kennedy entered the damaged silo just before 3:00 AM on September 19, 1980, to check conditions inside.

Suddenly, a massive explosion destroyed the 740-ton concrete silo door and hurled the nuclear warhead 100 feet from the complex.

The blast killed Livingston instantly while Kennedy survived with severe injuries to his lungs from breathing toxic oxidizer.

The accident injured twenty-one people as a fireball shot 200 feet into the night sky above the destroyed missile site.

The Accident Proved Minuteman’s Design Was Safer

The Damascus disaster triggered immediate safety reviews at all nuclear installations, including the Minuteman site at Delta-09 in South Dakota.

The Air Force sped up plans to retire the remaining liquid-fueled Titan II missiles after seeing how dangerous they could be.

The Minuteman’s solid propellant design eliminated the risk of catastrophic fuel leaks that destroyed the Arkansas silo.

The military completely changed how they handled nuclear weapons after the accident, creating new safety protocols that recognized the special dangers of liquid-fueled missiles compared to the more stable Minuteman system.

Visiting Minuteman Missile National Historic Site

Explore Cold War history at Minuteman Missile National Historic Site, where America’s nuclear defense system once stood ready. The site has three locations along I-90 in South Dakota.

The visitor center at exit 131 is open Tuesday through Saturday, 8am-4pm.

Tour the underground Delta-01 Launch Control Facility for $12 (adults) or $8 (youth 6-16), but book 24 hours to 90 days ahead as tours are limited to six people.
