The Damascus Titan missile explosion (also called the Damascus accident[1]) was a 1980 U.S. Broken Arrow incident involving a Titan II Intercontinental Ballistic Missile (ICBM). The incident occurred on September 18–19, 1980, at Missile Complex 374-7 in rural Arkansas when a U.S. Air Force LGM-25C Titan II ICBM loaded with a 9 megaton W-53 Nuclear Warhead had a liquid fuel explosion inside its silo.[2] Launch Complex 374-7 was located in Bradley Township, Van Buren County farmland just 3.3 miles (5.3 km) NNE of Damascus, and approximately fifty miles (80 km) north of Little Rock. (Coordinates: 35°24′50″N 092°23′50″W / 35.41389°N 92.39722°W / 35.41389; -92.39722 (374-7).)[3][4]

The incident began with a fuel leak at 6:30 p.m. on September 18, and culminated with the explosion at around 3:00 a.m. on September 19.[2]

The Strategic Air Command facility of Little Rock Air Force Base was one of eighteen silos in the command of the 308th Strategic Missile Wing (308th SMW), specifically one of the nine silos within its 374th Strategic Missile Squadron (374th SMS), at the time of the explosion.

At around 6:30 p.m. CDT on Thursday, September 18, 1980, two airmen from a Propellant Transfer System (PTS) team were checking the pressure on the oxidizer tank of a USAF Titan II missile at Little Rock AFB's Launch Complex 374-7. Due to time constraints when going into the silo, a ratchet – 3 ft (0.9 m) long weighing 25 lb (11 kg) – was taken instead of the newly mandated torque wrench. The 8 lb (3.6 kg) socket for the oxidizer tank fell off the ratchet and dropped approximately 80 feet (24 m) before bouncing off a thrust mount and piercing the missile's skin over the first-stage fuel tank, causing it to leak a cloud of its aerozine 50 fuel.

Aerozine 50 is hypergolic with the Titan II's oxidizer, dinitrogen tetroxide; i.e., they spontaneously ignite upon contact with each other. The nitrogen tetroxide is kept in a second tank in the rocket's first-stage, directly above the fuel tank and below the second-stage and its 9-megaton W-53 nuclear warhead.

Eventually, the missile combat crew and the PTS team evacuated the launch control center, while military and civilian response teams arrived to tackle the hazardous situation. There was concern for the possible collapse of the now empty first-stage fuel tank, which could cause the rest of the 8-story missile to fall and rupture, allowing the oxidizer to contact the fuel already in the silo.

The explosion

Early in the morning of Friday, September 19, a two-man PTS investigation team consisting of Senior Airman David Lee Livingston and Sergeant Jeff K. Kennedy entered the silo. Because their vapor detectors indicated an explosive atmosphere, the two were ordered to evacuate. The team was then ordered to reenter the silo to turn on an exhaust fan. Senior airman David Livingston reentered the silo to carry out the order and shortly thereafter, at about 3:00 a.m., the hypergolic fuel exploded – likely due to arcing in the exhaust fan. The initial explosion catapulted the 740-ton silo door away from the silo and ejected the second stage and warhead. Once clear of the silo, the second stage exploded. The W53 warhead landed about 100 feet (30 m) from the launch complex's entry gate; its safety features prevented any loss of radioactive material or nuclear detonation.[5][6]

After the explosion

Livingston died at the hospital, and 21 others in the immediate vicinity of the blast sustained various injuries; Kennedy struggled with respiratory issues from inhaling oxidizer but survived. Livingston was posthumously promoted to sergeant (E-5).[2] The entire missile launch complex was destroyed.[2]

At daybreak, the Air Force retrieved the warhead,[7][8] which was returned to the Pantex weapons assembly plant.[9]

The launch complex was never repaired. Pieces of debris were taken away from the 400 acres (1.6 km2) surrounding the facility, and the site was buried under a mound of gravel, soil, and small concrete debris. The land is now under private ownership.[2][10] The site was listed on the National Register of Historic Places on February 18, 2000.[2]

A 1988 television film, Disaster at Silo 7, is based on this event.[11]

Season 4, episode 4 (ep. 75) of Scorpion is largely based on this event.[12]

In September 2013, Eric Schlosser published a book titled Command and Control: Nuclear Weapons, the Damascus Accident, and the Illusion of Safety.[1] It focused on the explosion, as well as other Broken Arrow incidents during the Cold War.[1][13][14] A documentary film titled Command and Control from director Robert Kenner, based on Schlosser's book, was released on January 10, 2017. The film was broadcast by PBS as part of its American Experience series.[6]
