Agent Orange Okinawa
Newly discovered documents reveal that 50 years ago this week, the Pentagon dispatched a chemical weapons platoon to Okinawa under the auspices of its infamous Project 112. Described by the U.S. Department of Defense as “biological and chemical warfare vulnerability tests,” the highly classified program subjected thousands of unwitting American service members around the globe to substances including sarin and VX nerve gases between 1962 and 1974.
According to papers obtained from the U.S. Army Heritage and Education Center in Carlisle, Pennsylvania, the 267th Chemical Platoon was activated on Okinawa on Dec. 1, 1962, with “the mission of operation of Site 2, DOD (Department of Defense) Project 112.” Before coming to Okinawa, the 36-member platoon had received training at Denver’s Rocky Mountain Arsenal, one of the key U.S. chemical and biological weapons (CBW) facilities. Upon its arrival on the island, the platoon was billeted just north of Okinawa City at Chibana — the site of a poison gas leak seven years later. Between December 1962 and August 1965, the 267th platoon received three classified shipments — codenamed YBA, YBB and YBF — believed to include sarin and mustard gas.
For decades, the Pentagon denied the existence of Project 112. Only in 2000 did the department finally admit to having exposed its own service members to CBW tests, which it claimed were designed to enable the U.S. to better plan for potential attacks on its troops. In response to mounting evidence of serious health problems among a number of veterans subjected to these experiments, Congress forced the Pentagon in 2003 to create a list of service members exposed during Project 112. While the Department of Defense acknowledges it conducted the tests in Hawaii, Panama and aboard ships in the Pacific Ocean, this is the first time that Okinawa — then under U.S. jurisdiction — has been implicated in the project.
Corroborating suspicions that Project 112 tests were conducted on Okinawa is the inclusion on the Pentagon’s list of at least one U.S. veteran exposed on the island. “Sprayed from numbered containers” reads the Project 112 file on former marine Don Heathcote. Heathcote, a private first class stationed on Okinawa’s Camp Hansen in 1962, clearly remembers the circumstances in which he was exposed.
Throughout the late 20th century, rumors of Project 112 were widespread among U.S. veterans, but they were quickly dismissed by an American public unwilling to believe its government would test such substances on its own troops. However, following a series of TV news reports by CBS, the Pentagon admitted to the existence of Project 112 and promised to come clean on the issue.In 1961, as the Cold War deepened, the U.S. initiated a comprehensive overhaul of its defensive capabilities in more than 100 different categories; No. 112 on this list was the study of CBW. Envisaged by President John F. Kennedy’s secretary of defense, Robert McNamara, as “an alternative to nuclear weapons,” Project 112 proposed experiments in “tropical climates” and, to evade laws regulating human testing in the U.S., it suggested the use of overseas “satellite sites.” Fulfilling both prerequisites, Okinawa must have seemed a perfect choice.
That disclosure began in 2000, when the Pentagon claimed that there had been 134 planned tests, of which 84 had been canceled. The experiments it admitted carrying out included the spraying of troops in Hawaii with E. coli, subjecting sailors to swarms of specially bred mosquitoes, and exposing troops in Alaska to VX gas. The Pentagon stated that no participants had been harmed in these tests.
Throughout the Cold War until 1969, Washington adhered to a strict policy of neither confirming nor denying the presence of CBW on Okinawa. In all likelihood, it would have continued to do so, were it not for the events of July 8 of that year. On that day, American service members were conducting maintenance on munition shells at the Chibana depot when one of the missiles sprung a leak. Twenty-three troops and one civilian fell sick from exposure to the missile’s contents — likely VX gas — and were hospitalized for up to a week.
Considering the toxicity of such weapons, those exposed escaped lightly. Nevertheless, when the accident was reported, its ramifications were far-reaching: The Pentagon was forced to acknowledge its chemical arsenal on Okinawa — infuriating local residents — and promised to remove the entire stockpile before the island’s reversion to Japanese control in 1972.

Operation Red Hat, the mission to transport the weapons off the island, was organized by the same man who had brought them to Okinawa two decades previously: John. J. Hayes (by then a general). It also involved the 267th Chemical Platoon, which had been renamed the 267th Chemical Company. During two separate phases in 1971, the military shipped thousands of truckloads of sarin, mustard gas, VX and skin-blistering agents from Okinawa to U.S.-administered Johnston Island in the middle of the Pacific. The consignments totaled 12,000 tons — a terrifying amount considering that many of these substances’ fatal dosage is measured in milligrams. After the final shipment had left the island, Hayes assured journalists, “Every round of toxic chemical munitions stored on Okinawa has now been removed.”
This year marks 60 years since the first delivery of chemical weapons to Okinawa; this week is the 50th anniversary of the launch of Project 112 on the island. However, the continuing illnesses suffered by U.S. veterans including Heathcote and Mohler suggest this problem is far from a purely historical matter — and only now are potential correlations between toxic munitions and illnesses among Okinawan residents coming to light.
In the near future, Washington plans to return a number of U.S. installations on Okinawa to civilian usage. However, just as former U.S. CBW storage sites elsewhere — such as the Rocky Mountain Arsenal and Johnston Island — remain dangerously contaminated, Okinawan land is likely to be handed back in a similarly toxic state.
Under the current U.S.-Japan Status of Forces Agreement, the host government is solely responsible for the cleanup of former bases — a task that’s expected to set Japanese taxpayers back hundreds of millions of dollars. With the true cost in terms of health and capital yet to be determined, there is a real risk that these weapons of mass destruction will poison not only the soil but also American-Japanese-Okinawan relations for decades to come.
