Exclusive: Red Hat’s lethal Okinawa smokescreen



In July 1969, a leak of chemical weapons on Okinawa sickened more than 20 U.S. soldiers and laid bare one of the Pentagon’s biggest Cold War secrets: the storage of toxic munitions outside of continental United States.

Public outrage following the Okinawa accident forced the White House to launch Operation Red Hat — codename for a mission to remove the chemicals from the island.

For more than four decades, details of that project have been kept firmly under wraps. But now, newly disclosed scientific studies — and accounts from U.S. veterans who participated in Operation Red Hat — are casting light on the mission and exposing what truly occurred — including the alleged dumping of chemical weapons off the coast of Okinawa.

In July 1969, as the eyes of the world were focused on Neil Armstrong’s mission to the moon, U.S. service members and residents on Okinawa had war on their minds.

Since 1945, the island had been under U.S. jurisdiction, and by 1969 the Pentagon’s “Keystone of the Pacific” was the primary staging post for the conflict in Vietnam. Ships from the U.S. funneled troops and materiel through the island’s ports while Kadena Air Base in central Okinawa had become the world’s busiest airport as massive B-52s bombers took off from its runways to rain death and destruction across much of southeast Asia.

Unknown to most people on Okinawa — service members and civilians alike — the island was also bristling with the full spectrum of America’s weapons of mass destruction, including hundreds of nuclear warheads and a large arsenal of chemical munitions.

By then, most countries had renounced the use of toxic weapons under the 1925 Geneva Protocol, but during the Cold War both the U.S. and the Soviet Union cranked up their production. In fact the first U.S. chemical weapons were taken to Okinawa during the 1950-53 Korean War, with further shipments between 1962 and 1963. The stockpile was widely assumed by leading historians of chemical warfare, including Jonathan B. Tucker — author of 2006′s comprehensive history of those munitions, “War of Nerves” — to consist of three main substances: mustard agent, sarin and VX.

First deployed in World War I, mustard agent is an oily liquid smelling more like garlic than the kitchen condiment after which it was named; upon contact with the skin, it triggers large blisters. It also has the potential to damage DNA and can be lethal.

Sarin, named from the initials of its Nazi German creators, is a nerve agent — the most deadly family of chemical weapons. It causes violent muscle contractions that lead to death from asphyxiation. When Aum cultists released 5 kg of 30-percent-pure home-made sarin in the Tokyo subway system in 1995, 13 people were killed and more than 1,000 injured.

VX is a variant of nerve gas that was the most powerful poison in the U.S. arsenal when it was created in the mid-1950s — with just 1 kg of the substance able to take the lives of hundreds of thousands of people. In 1969, according to later newspaper reports, including in the New York Times, there was an estimated 1.9 million kg (1,900 metric tons) of VX stored on Okinawa.

The U.S. chemical weapons arsenal was stockpiled at Chibana Ammunition Depot, a hilltop installation next to Kadena Air Base. Access to the sprawling depot was tightly controlled, but a herd of goats was given free rein in the hope that any untoward behavior by those animals could warn of a possible toxic leak. In the storage bunkers, meanwhile, there were caged white rabbits whose bulbous pink eyes would show pinpricked pupils — one of the initial signs of nerve-gas exposure — if an accident occurred.

However, the depot’s animal early-warning systems were unable to prevent what happened there on July 8, 1969. Although the Pentagon has never officially disclosed details of the accident, it is possible to infer a picture of events from U.S. officials’ memoirs.

In his 1979 book “White House Years,” Henry Kissinger — who, in 1969, was U.S. President Richard Nixon’s national security adviser — blamed the accident on an unnamed U.S. army major whose “aesthetic sense exceeded his judgment” as he ordered a maintenance crew to sandblast the chemical munitions’ containers prior to repainting them a different color.

The work caused one or more of the munitions containers to leak their contents — though to this day experts disagree whether it was sarin or VX. Twenty-three troops and one American civilian were exposed and hospitalized with mild symptoms of contamination. Some were released that day, while the most seriously affected — in what must have been a miniscule release — took a week to recover.

According to a report in U.S. archives of Okinawa High Commissioner Lt. Gen. James Lampert’s oral debriefing when he left Okinawa in 1972, he first learned of the accident when he was woken on the night of July 8, 1969, by a phone call from Maj. Gen. Chuck Horner, the U.S. Army officer in charge of the weapons (who was possibly also the unnamed officer mentioned by Kissinger). Lampert’s report was quoted as saying Horner suggested the damaged munitions be dumped at sea, but the high commissioner said he would need permission from the Pentagon first.

As far as is known, Lampert’s account made no further mention of the proposed sea dump — and it seems certain the Pentagon would have hidden the accident had a Wall Street Journal reporter not got wind of it and published a front-page story on July 18, 1969.

However, the article sparked fury on Okinawa — and also humiliated the U.S. government just as it was striving to claim the moral high ground in Vietnam and fend off international accusations that its widespread use of CS gas and Agent Orange in that conflict amounted to it conducting illegal chemical warfare. Four days after the Wall Street Journal article ran, the Pentagon announced it would remove its chemical weapons from Okinawa as soon as possible.

After that, with so much international attention focused on the island, Washington launched a public relations campaign to reassure the world that it would remove these munitions safely. At its core was a cheery propaganda reel titled “Operation Red Hat — Men and a Mission.”

In the film, the narrator explains that the project’s name was selected “by a little old lady in tennis shoes working at the Pentagon” — and in keeping with that sugar-coated approach, bright-red hard hats and cute pin badges were issued to service members assigned to the project.

Despite the Pentagon’s pledge to act quickly — and the indisputable risks of retaining its leaky arsenal at Chibana — it took a full 18 months for the first phase of Operation Red Hat to begin.

According to the film “Men and a Mission,” in January 1971, nine trucks carrying chemical weapons drove the 11 km from Chibana to Ten Gan Pier, a long jetty on Okinawa’s east coast. Seven months later, in early August, the U.S. military embarked upon the second phase of the operation, which involved the main bulk of its chemical arsenal. This time, for 38 days non-stop, a team of 150 drivers worked 14-hour shifts to transport 1,213 trailer-loads of munitions from Chibana to Ten Gan Pier. In sum, the chemical mines, rockets, bombs and barrels added up to 13,000 tons.

Tim Gravely, one of the soldiers who helped to load the ships at Ten Gan Pier, still well remembers the sense of danger surrounding the project.

“Just in case there was a leak, they gave us large hypodermic needles to wear on our belts. We were supposed to hit ourselves on the leg and the needle would shoot out, injecting medicine,” he told The Japan Times.

The syringes probably contained atropine, an antidote to nerve gas, and Gravely came close to using it on Aug. 25, 1971, when a crane dropped 15 chemical rockets into a ship’s hold.

“Five or six guys jumped on my forklift and we drove off as fast as it would go to get off the pier. I didn’t want to have to use those needles because they were so nasty looking,” Gravely recalls.

Nobody was injured in the incident — the rockets were later reported by the U.S. media to be packed with sarin — and there were no further accidents logged throughout the operation.

According to the Pentagon, the last of the toxic munitions left Okinawa on Sept. 10, 1971, headed way across the North Pacific to Johnston Island, which lies around 1,390 km off the Hawaiian islands and was then, like Okinawa, entirely under military jurisdiction.

On the stern of the final ship to leave Ten Gan Pier, soldiers hung a large sign painted with the “Loony Tunes” catchphrase, “That’s All Folks!” Following its departure, Okinawan officials scattered handfuls of salt to ritually purify the area.

The bright-red hard hats; the badges; the movie: At the time, the PR campaign accompanying Operation Red Hat was unprecedented in U.S. military history. Now, more than four decades later, the reasons for this seem clear: It was a smokescreen designed to camouflage what truly occurred during the removal of those chemical munitions.

Among the first ruses seems to have been Kissinger’s claim that the 1969 leak at Chibana was the fault of an unnamed major whose “aesthetic sense exceeded his judgment.”

His assertion detracted from the grim reality that, by the late 1960s, the U.S. military’s chemical weapons had fallen into deplorable disrepair. According to Tucker, in “War of Nerves,” during the mid-1950s the U.S. Army had cut corners in its sarin production process to save money. This led to a less-pure concentration that, being acidic and laden with heavy metals, started to eat through the walls of the rockets armed with it. On Okinawa, the problem would likely have been exacerbated by the humid, salty air.

When such leaks occurred on bases in the United States, the military followed standard operating procedure for disposal: The defective containers were taken out to sea and thrown overboard (see sidebar).

Indeed, that had been the procedure proposed to High Commissioner Lampert following the Chibana leak in July 1969 — and in the late 1960s, Okinawan newspaper journalists heard from their on-base sources that’s exactly what happened in the waters off Okinawa. However, when these reporters pursued the story, their informants suddenly clammed up for fear of losing their jobs.

Now, however, new evidence supplied by U.S. veterans who participated in the sea disposal of chemical weapons makes it possible to confirm those 1960s accounts.

According to former service members, an operation took place in autumn 1969, around two months after the Chibana leak. Tom Westfall was then serving with the 895th Military Police Company, and helped oversee the transportation of munitions from Chibana Ammunition Depot.

“It was an all-hands effort with cooks, supply clerks and road duty MPs manning intersections and escort duty. We all got the atropine training and were issued gas masks,” Westfall told The Japan Times in an email interview last month.

Westfall and his fellow police officers monitored the route the trucks took to ensure there were no accidents and there was no interference from anti-base protesters. He recalls that there were six trucks in total and he’d heard what was going to happen to their cargo. “There were discussions about the stuff being dumped offshore and whether or not that was safe. Also about how long the barrels would last until they released the materials — and would the salt water disperse it?”

James Spencer, then a 20-year-old U.S. Army stevedore assigned to the 412th Transportation Company, stated in a recent interview that the destination of the trucks Westfall supervised was Ten Gan Pier. He said he accompanied what he’d been told by his superiors were chemical weapons as they were loaded onto a ship on which he then sailed.

“The weapons were in large steel containers approximately 8 or 10 feet (2.4 to 3 meters) long and about 3 feet (90 cm) in diameter. Some of them looked corroded. We always wore a gas mask and rubber gloves when we were near them,” Spencer told The Japan Times.

Like Westfall, Spencer was also issued with a syringe to administer an emergency antidote if the need arose (it didn’t).

Spencer remembers what happened when the ship reached its designated dump location. “We used a winch to lift the containers out of the hold and then a large fork lift to push them overboard. I am not sure how many we dumped — it was a lot. The entire operation took 48 hours.”

When approached for comment for this article, Pentagon-based U.S. Army spokesman, Dave Foster, said that after a preliminary check of archives, the army had found “no record of any disposal of chemical or conventional munitions in the autumn of 1969 off the east coast of Okinawa, nor on any other date.”

However, Foster seemed to acknowledge the U.S. military’s poor track record of documenting its marine disposal when he urged veterans to forward their allegations to the U.S. Army Historical Research Team at Aberdeen Proving Ground in Maryland so the site could be added to its archives. Since 2006, the team has been responsible for mapping U.S. military sea-dump sites around the world, and it supplies Congress with an annual report to mitigate the risks of these toxins.

The Pentagon’s lackadaisical approach to safety during the Cold War extended to the way it transported chemical weapons in the two main 1971 phases of Operation Red Hat.

In 1997, scientists from the Edgewood Chemical Biological Center based at the Aberdeen Proving Ground ran tests on the containers used to ship the munitions from Okinawa to Johnston Island. They discovered that more than one in four — 26 percent — of them were mislabeled.

Furthermore, the tests conducted on containers by Edgewood scientists suggested Okinawa had been the storage site of a chemical munition not previously suspected — one known as lewisite.

Designed to be more toxic than mustard agent, lewisite’s immediate effects include uncontrollable vomiting — while in the long term it can cause blindness and permanent damage to the respiratory system. What also makes lewisite particularly frightening is that it has been linked to dangerous levels of arsenic in fish many decades after being abandoned at sea (see sidebar).

Moreover, it appears yet another poison was omitted from officials’ accounts of Operation Red Hat — the toxic defoliant Agent Orange.

In 1970, after almost a decade of its use in Vietnam, the U.S. military was forced by Congress to stop spraying the substance after studies showed it caused birth defects and cancer. Following the ban, the U.S. had tens of thousands of barrels of Agent Orange to deal with — so it was decided to send them to its default toxic dumpsite: Johnston Island.

Although the Pentagon vehemently denies that Agent Orange was ever present on Okinawa, more than 150 U.S. veterans have claimed to the Department of Veterans Affairs that they were exposed to the substance on the island. Among those claimants is stevedore James Spencer, who says he sprayed it near Ten Gan Pier in 1968 to clear undergrowth.

Official U.S. records cite the existence of a stockpile of Agent Orange in 1971 at Kadena; while a U.S. Army-funded report about Johnston Island states that there were 25,000 barrels of Agent Orange on Okinawa some time prior to 1972.

Considering the 1970 White House ban on Agent Orange, it seems the Pentagon may well have used Operation Red Hat as convenient cover to ship its Okinawa defoliant stockpile off the island.

Donald Wilson, a former U.S. special forces Green Beret — who was interviewed for “I Sprayed Agent Orange on Okinawa,” a TV Asahi documentary aired in Japan in October 2012 — stated that he had seen hundreds of barrels with Agent Orange’s tell-tale orange stripes around them being loaded into the holds of one of the Operation Red Hat ships.

Julio Batista, a former U.S. soldier who helped offload chemical weapons on Johnston Island in 1972, also recalls seeing similar barrels. “There were herbicides involved in Operation Red Hat. The barrels I sat on were 55-gallon (208-liter) drums. Each drum was painted in the middle identifying the agent,” Batista told The Japan Times by email in spring 2012.

Batista believes that he and dozens of other service members stationed on Johnston Island were sickened from their exposure to toxins transported at the time.

Corroboration that Agent Orange was shipped from Okinawa during Operation Red Hat has also come from an unexpected source: U.S. Air Force Gen. Richard B. Myers, retired Chairman of the U.S. Joint Chiefs of Staff (2001-05).

In 2004, Myers prepared a memorandum following Congressional enquiries into defoliant usage on Okinawa. Titled “Agent Orange/Operation Red Hat documents,” it catalogs 18 reports spanning a period from August 1969 — the month after the Chibana leak — to March 1972. The list includes documents with tantalizing titles such as “Disposal of Herbicide Orange” and “Relocation of chemical weapons and agents from Okinawa.”

Repeated attempts since April 2011 to access those 18 reports — including requests under the U.S. Freedom of Information Act — have been stymied by the Pentagon. To date, of the 18 files on the list, only six have been declassified — and two of those contain dates that do not match those on the original list.

According to Lampert in his final report to Washington as high commissioner, dated May 14, 1972, Operation Red Hat was one of the U.S. military’s “most controversial and emotionally charged projects.” But Lampert also surmised there that it had been accomplished “with complete safety.”

Today, that optimism seems misplaced. A large number of the U.S. service members involved in transporting and storing those weapons on Johnston Island appear to have been sickened by their work; likewise, former service members believe they are ill from exposure to Agent Orange on Okinawa. The U.S. government has refused to help either group of veterans.

Ongoing contamination from these substances is another potentially lethal problem — one not only affecting the marine environment where the munitions were purportedly dumped, but also at Chibana Ammunition Depot — today still a U.S. military facility now called Kadena Ammunition Depot.

The U.S. military has a long and nasty history of contaminating its bases on Okinawa — including the dumping of carcinogenic PCBs on Onna Communication Site prior to 1995; irradiating tiny Torishima Island with depleted uranium ordnance in 1996; and, most recently, it seems that fuels are contaminating the groundwater beneath Camp Kuwae.

However, until now nobody suspected that U.S. chemical weapons continued to pose a danger.

In 1971, Okinawa officials rejoiced when the last of those munitions were taken away — but it seems it will require a lot more than salt to purify their island of the poisonous legacy of these weapons of mass destruction.

Very interesting article, but I failed to see any "left-wing bias". Unless you are suggesting that only the left wing is willing to discuss the possibility that a democratically elected government would lie to the electorate.

I must second Bill in commending you for posting such an interesting article and wondering where any bias worthy of mention might be found.

Also, it is pretty frightening that even after all said and done in that piece, the US is still probably among the more responsible nations having/had significant b/c weapons stocks. My impression is that the practices described in the article are thankfully unthinkable today. The amounts of agents listed are flabbergasting and I can't help wondering whether anyone ever thought of even remotely acceptable disposal methods - intentionally lethal use notwithstanding - while building that absurdly large stockpile: those days weren't exactly awash in foresight on such matters. The current care and sophistication required in dealing with or disposing of b/c weapons is evident enough solely in the accompanying gear that units dealing with such matters carry. Still, we have situations like Syria where no amount of expertise or fancy materiel might entirely suffice.

I also concur with Tim Gravely's (quoted in the article) statement that field atropine kits are cringe inducing instruments - the needle is t-h-i-c-k because you're gonna have to stick it in your thigh through whatever you're wearing which is more than likely something sturdy enough to survive a battlefield. No time to start dropping trou nor hesitation, none of that "you m-i-g-h-t feel a little sting" stuff.

Better than the alternative, almost certainly. The initial time, amount and type of exposure might have something to do with that.

A lot of members work in the defense industry and expect a very conservative description of operations. For example:
Kadena Air Base in central Okinawa had become the world’s busiest airport as massive B-52s bombers took off from its runways to rain death and destruction across much of southeast Asia.

Could be interpreted as liberal when they were expecting:
Kadena Air Base in central Okinawa had become the world’s busiest airport as massive B-52s bombers took off from its runways to strategically deliver munitions in support of various campaigns across much of southeast Asia.

My definition of liberal is a little different. I'd have to see the word "imperialist" in there before I'd get really concerned...

If there is a bias (left, right or Imperial) that implies some of the information is not accurate or at least not complete. Which information? (Provide examples, correct information, and sources. Bonus points for proving that the error/omission was politically motivated.)

There might be some truth in the article, but then again, there may not. The Japan Times is well-known for it's inability to logically look at issues, and when the issues are complex any fact-checking goes out the window.
