Titan II Missile Accident (1965)
Titan II ICBM Launch Complex 373-4 near Searcy (White County) was the site of an accident on August 9, 1965, in which fifty-three workers were killed—the largest loss of life ever suffered in a U.S. nuclear weapons facility.
Titan II ICBM Launch Complex 373-4 was one of eighteen Arkansas launch complexes operated by the 308th Strategic Missile Squadron headquartered at the Little Rock Air Force Base in Jacksonville (Pulaski County). Construction of Launch Complex 373-4 had commenced on January 3, 1961, and was finished on July 31, 1962—the first of the 308th’s sites to be completed and the first to go on alert (meaning that it was fully operational and ready to respond) on May 16, 1963. After it had operated for a few years, the U.S. Air Force initiated Program Yard Fence, in which construction crews were brought in to further gird the facilities against Soviet nuclear attack. During this process, workers improved the launch duct doors and conducted other modifications. The missile at 373-4, fully loaded with fuel and oxidizer although the re-entry vehicle and warhead had been removed, was in the launch duct during the improvements. A four-man air force crew manned the site’s control center while contractors worked in the launch duct.
On August 9, 1965, civilian construction workers were working in all nine levels of the launch duct, painting and flushing the hydraulic systems that operated the steel platforms beside the missile. At about 1:00 p.m. the launch duct was suddenly filled with intense heat and billowing smoke. Gary Lay, a seventeen-year-old who was working his first day at the job, was standing with twelve co-workers on Level 2 when he felt a rush of warm air and turned to see flames behind him. The lights went out, and emergency lights turned on. As the rest of the men rushed toward the emergency escape ladder, Lay instead went through the flames to the cableway leading to the control center, suffering second- and third-degree burns. Another worker, Hubert A. Saunders, who had worked at other launch complexes and knew the layout, made his way from Level 1 to the cableway when he saw smoke and also reached the control center, bringing his paint can and brush with him. Saunders suffered mild smoke inhalation.
Lay and Saunders were the only two of the fifty-five men who were working in the launch duct to survive the fire, which had rapidly sucked all of the oxygen out of the launch duct, asphyxiating fifty-two workers. The fifty-third victim drowned in hydraulic fluid. Air force crews quickly reached the complex and put out a few small fires and began recovering the men’s bodies even as they dealt with another potential catastrophe: When power failed in the launch duct, the air-conditioning turned off, raising temperatures in the silo and creating conditions that could lead to an explosion of the oxidizer within the missile, which had a boiling point of seventy degrees. By 10:00 p.m. the temperature in the launch duct hit eighty degrees. It then began to fall, averting the possibility of a larger accident. The last worker’s body was removed at 5:30 a.m. on August 10.
Investigators determined that a welder working on Level 3 had accidentally hit a hydraulic line with his welding rod, rupturing the hose and causing the spray of hydraulic fuel to catch fire. While attributing the tragedy to human error, the investigators also cited inadequate ventilation in the launch duct, lack of an independent source of power for the silo’s elevator, and absence of alternative exits as contributing factors to the large loss of life in the accident.
Coincidentally, the missile that was in the launch duct, serial number 62-0006, was the same missile that later exploded in Launch Complex 374-7 in Southside (Van Buren County) just north of Damascus (Van Buren and Faulkner counties) on September 19, 1980.
Launch Complex 373-4 returned to alert status on September 29, 1966. As the Titan II program was being phased out, it was taken off alert for good on February 18, 1987, after twenty-four years of service.
