Deep within the classified corridors of Fort Detrick, Maryland — America’s biological warfare research center — the Central Intelligence Agency quietly ran a program that most Americans still know nothing about. It wasn’t MK-ULTRA, the infamous mind control project that has been the subject of countless books and documentaries. This was something older, something more primal, and in many ways more disturbing: a secret biological weapons development program codenamed MK-NAOMI, designed to give the CIA its own independent arsenal of lethal and incapacitating biological and chemical agents — tools for assassination, covert sabotage, and population control — that operated entirely outside the normal chain of military command.
What Was MK-NAOMI?
MK-NAOMI was a joint CIA-Army program that ran from the early 1950s through at least 1970. The “MK” prefix placed it within the CIA’s Technical Services Staff (TSS) umbrella of covert programs — the same bureaucratic family that included the more notorious MK-ULTRA. NAOMI stood for nothing officially; the name was simply a cryptonym. The program’s core purpose was to develop, store, and weaponize biological agents and toxins that the CIA could deploy in covert operations without the knowledge of the U.S. military or civilian leadership.
The relationship with Fort Detrick was the program’s operational backbone. Fort Detrick was already the center of the U.S. Army’s biological warfare research, home to teams of scientists who had been recruited after World War II — including some with connections to the Japanese Unit 731 program, which had conducted horrific biological experiments on prisoners of war. The CIA’s arrangement with Fort Detrick gave it access to the Army’s research facilities and scientific expertise while maintaining its own classified stockpile of materials and its own chain of command for deployment decisions.
The Arsenal: What They Built
The Church Committee investigations of 1975 — the most significant congressional inquiry into CIA activities ever conducted — produced the most detailed public accounting of what MK-NAOMI actually developed and stockpiled. The findings were genuinely disturbing.
According to testimony before the Church Committee, the CIA maintained a secret biological and chemical arsenal at Fort Detrick that included:
- Shellfish toxin (saxitoxin) — one of the most potent natural poisons known, capable of causing death in tiny quantities. The CIA maintained enough to kill thousands of people.
- Cobra venom — stockpiled in quantity for potential assassination operations.
- Botulinum toxin — the neurotoxin produced by Clostridium botulinum, then and now the most acutely toxic substance known.
- Anthrax and other bacterial agents for potential use in covert operations.
- Various incapacitating agents — substances designed not to kill but to temporarily disable targets, including materials that could be delivered in food, water, or aerosol form.
These weren’t merely research samples. They were operational stockpiles, maintained in specialized storage conditions and associated with specific delivery systems: dart guns disguised as ordinary objects, aerosol dispensers, injection mechanisms designed to leave no trace. The CIA had developed what amounted to a covert assassination toolkit, stocked with biological and chemical weapons.
The Assassination Connection
The Church Committee’s investigation into MK-NAOMI was triggered in part by its parallel investigation into CIA assassination plots — against Fidel Castro, Patrice Lumumba of the Congo, and others. What the investigators found was a direct connection between the bioweapons program and assassination planning.
In the case of Patrice Lumumba, the CIA had planned to use biological agents to kill the Congolese independence leader. CIA Director Allen Dulles had authorized the operation; a CIA officer named Joseph Scheider (using the alias “Joe from Paris”) had hand-carried a biological weapon — reportedly a highly virulent form of tuberculosis — to Leopoldville (now Kinshasa) with instructions to introduce it into Lumumba’s food or toothbrush. The operation was ultimately abandoned when Lumumba was captured and killed by other means, but the weapons had been prepared and transported.
Against Fidel Castro, the CIA’s assassination planning was extensive and baroque. While most public attention has focused on the Mafia-connected plots, MK-NAOMI materials were also implicated. CIA scientists at Fort Detrick developed a poison that would cause Castro’s beard to fall out (a less-than-lethal plot designed to humiliate him), as well as more serious incapacitating and lethal agents intended for delivery through various means.
Nixon’s Order and What It Revealed
In November 1969, President Richard Nixon issued an executive order renouncing biological weapons and ordering the destruction of all U.S. biological warfare stockpiles. This was a genuine and historically significant arms control action. What Nixon apparently didn’t know — or chose not to know — was that the CIA maintained its own separate stockpile under MK-NAOMI that was not subject to his order.
When Director of Central Intelligence Richard Helms learned of Nixon’s order, he did not immediately destroy the CIA’s stockpile. Instead, he ordered that the materials be retained for “defensive research purposes.” The shellfish toxin, cobra venom, and other agents sat in a CIA vault at Fort Detrick for years after Nixon’s order, in direct violation — if not of the letter — of the spirit of the president’s directive.
It was only when James Schlesinger became CIA Director in 1973 and ordered a comprehensive review of CIA activities that the existence of the stockpile came to light internally. When William Colby became Director later that year and prepared the document known as the “Family Jewels” — a compilation of CIA activities that potentially violated the Agency’s charter — the MK-NAOMI stockpile was among the items listed. The “Family Jewels” document would eventually trigger the Church Committee investigations.
The Fort Detrick Ecosystem
To understand MK-NAOMI, you have to understand the larger ecosystem of Fort Detrick. The installation in Frederick, Maryland was the hub of American biological warfare research from World War II through the Nixon-era shutdowns. Within its fences, scientists worked on everything from weaponizing anthrax to developing defenses against Soviet bioweapons. The civilian and military research programs were extensive, expensive, and deeply classified.
The CIA’s arrangement with Fort Detrick gave the Agency access to this scientific infrastructure while maintaining plausible deniability. If the bioweapons research was technically housed within Army facilities, the CIA could argue it was simply using existing capabilities rather than running its own illegal weapons program. This distinction mattered legally — the CIA’s charter explicitly prohibited it from conducting domestic operations, which a standalone bioweapons facility on CIA grounds might have constituted.
But the distinction also created gaps in accountability. The Army scientists at Fort Detrick answered to Army command. The CIA officers overseeing MK-NAOMI answered to the Technical Services Staff. Nobody was clearly in charge of ensuring the program complied with presidential orders or congressional oversight. It was the kind of accountability vacuum that allowed the stockpile to persist even after Nixon’s order.
Testing: Who Were the Subjects?
The most troubling dimension of MK-NAOMI, even more troubling than the assassination weapons, is the question of human testing. The CIA’s related program MK-ULTRA is well-documented as having conducted non-consensual experiments on unwitting subjects. To what extent did MK-NAOMI do the same with biological agents?
The Church Committee’s investigation found evidence that was suggestive but not definitive. What’s documented is that both the CIA and the Army conducted biological testing on human subjects during this period — the Army’s own testing programs, which overlapped with MK-NAOMI, included experiments conducted on soldiers without their full informed consent. Whether CIA-specific biological agents were ever tested on unwitting civilians — a logical extension of what MK-ULTRA was doing in the chemical and psychological domain — has never been fully established from declassified records.
This gap in the record is itself significant. Many MK-ULTRA documents were destroyed by order of Director Helms in 1973, just before Helms left the Agency. If MK-NAOMI documents were similarly handled, the full picture of what was tested and on whom may never be recoverable.
The Program’s Legacy
MK-NAOMI officially ended in 1970, though the stockpile persisted until at least 1975. The Church Committee’s exposure of the program led to new executive orders restricting CIA activities and stronger congressional oversight. The Biological Weapons Convention of 1972, to which the United States became a signatory, prohibited the development, production, and stockpiling of biological weapons — though it notably lacked enforcement mechanisms.
The questions MK-NAOMI raises remain urgent. If the CIA could maintain a secret bioweapons stockpile for two decades, in defiance of a presidential order, with no meaningful accountability — what else might be happening in classified programs today? How confident can we be that similar programs don’t exist in other countries, or in the classified corners of our own national security apparatus?
Down the Rabbit Hole
MK-NAOMI is just one node in a much larger web. Here’s where to dig next:
- MK-ULTRA: The CIA’s mind control program that subjected unwitting citizens to LSD, electroconvulsive therapy, and psychological torture. MK-ULTRA and MK-NAOMI shared the same bureaucratic home and many of the same personnel.
- The Family Jewels: The CIA’s own internal document cataloging its most questionable activities, compiled in 1973 and partially declassified in 2007. A remarkable window into what the Agency itself thought it was doing wrong.
- Unit 731 and Operation Paperclip: The U.S. government’s recruitment of Japanese biological warfare scientists (and German weapons scientists) after World War II, and what knowledge they brought with them.
- The Sverdlovsk Anthrax Leak (1979): An accident at a Soviet biological weapons facility that killed dozens and demonstrated that the Soviet Union was continuing its bioweapons program despite the Biological Weapons Convention — raising questions about whether the U.S. responded in kind.
- Dark Winter (2001): A U.S. government exercise simulating a bioterror attack that took place just months before the 2001 anthrax letter attacks — and the strange connections some researchers have drawn between the exercise participants and the subsequent investigation.
