Enhanced Radiation Warhead ( ERW ) also known as Neutron bomb, is a type of tactical nuclear weapon designed specifically to release a large portion of its energy as energetic neutron radiation rather than explosive energy. An ERW explosion is typically about one-tenth as powerful as that of a comparable fission-type atomic bomb because standard thermonuclear weapons create increased explosive yield by capturing their neutron radiation. Although their extreme blast and heat effects are not eliminated, the increased radiation released by ERWs is meant to affect biological material (which may otherwise be protected from the heat of an explosion) rather than material infrastructure. ERWs are still much more destructive than conventional bombs. They were formerly built mainly by the United States.
HISTORY
Sam Cohen is considered the father of the neutron bomb. In the summer of 1958 he began investigating the possibility of large thermonuclear weapons. In his research, Cohen argued that if the uranium casing of a hydrogen bomb were removed, the neutrons released would travel great distances, penetrating even well-shielded structures with lethal doses of radiation and harming anyone inside.
Neutron bombs could be used as strategic anti-ballistic missile weapons or as tactical weapons intended for use against armored forces; in fact, the neutron bomb was originally conceived as a weapon that could stop Soviet armored divisions from overrunning Western Europe without destroying Western Europe in the process.
As an anti-ballistic missile weapon, an ER warhead was developed for the Sprint missile system as part of the Safeguard Program to protect United States cities and missile silos from incoming Soviet warheads by damaging their electronic components with the intense neutron flux.
Tactical neutron bombs are primarily intended to kill soldiers who are protected by armor. Armored vehicles are extremely resistant to blast and heat produced by nuclear weapons, so the effective range of a nuclear weapon against tanks is determined by the lethal range of the radiation, although this is also reduced by the armor. By emitting large amounts of lethal radiation of one of the most penetrating kinds, ER warheads maximize the lethal range of a given yield of nuclear warhead against armored targets.
At the same time, modest fallout shelters of ordinary design will protect civilian populations. According to Sam Cohen's book, one of the best kept secrets is that the bomb is an effective defensive weapon against an armor attack.
One problem with using radiation as a tactical anti-personnel weapon is that to bring about rapid death of the individuals targeted, a radiation dose that is many times the lethal level must be administered. A radiation dose of 6 Gy is normally considered lethal. It will kill at least half of those who are exposed to it, but no effect is noticeable for several hours. Neutron bombs were intended to deliver a dose of 80 Gy to quickly kill targets. A 1 kt ER warhead can do this to a T-72 tank crew at a range of 690 m, compared to 360 m for a pure fission bomb (the blast would likely destroy it, however). For a 6 Gy dose, the distances are 1100 m and 700 m respectively, and for unprotected soldiers 6 Gy exposures occur at 1350 m and 900 m. The lethal range for tactical neutron bombs exceeds the lethal range for blast and heat even for unprotected troops, which is likely the reasoning for the idea that a neutron bomb destroys life and not infrastructure. If a neutron bomb were detonated at the correct altitude, deadly levels of radiation would blanket a wide area with minimal heat and blast effects when compared to a nuclear weapon of conventional design.
The neutron flux can induce significant amounts of short-lived secondary radioactivity in the environment in the high flux region near the burst point. The alloys used in steel armor can develop radioactivity that is dangerous for 24–48 hours. If a tank exposed to a 1 kt neutron bomb at 690 m (the effective range for immediate crew incapacitation) is immediately occupied by a new crew, they will receive a lethal dose of radiation within 24 hours.
One significant drawback of the weapon is that not all targeted troops will die or be incapacitated immediately. After a brief bout of nausea, many of those hit with about 5-50 Sv of radiation will experience a temporary recovery (the latent or "walking ghost phase") lasting days to weeks. Moreover, these victims would likely be aware of their inevitable fate and react accordingly.
3 Types ERW :
W66 Thermonuclear Warhead
was used on the Sprint anti-ballistic missile system, designed to be a short range interceptor to shoot down incoming ICBM warheads. The W66 was a low yield (details not declassified, but reportedly a few kilotons) thermonuclear bomb, which was the first Neutron bomb (technically Enhanced Radiation weapon) fielded anywhere in the world. It was designed to destroy or disable an incoming warhead using neutron flux, and to a lesser extent X-ray and blast effects.
The W66 was 18 inches in maximum diameter and 35 inches long, with a weight of around 150 pounds.
Retired soon thereafter, along with the missile system.
W70 Mod 3 warhead
W70 is the designation for a tactical nuclear warhead developed by the United States in the early 1970s. The Lawrence Livermore National Laboratory designed W70 was used on the MGM-52 Lance. About 1250 were built in total. The warhead had a variable yield of between 1 and 100 kilotons, selectable by the user. The design dates from 1973.
The W70-3 was a modified version of the W70 and one of the first warheads to be battlefield-ready with an "enhanced radiation" (i.e. neutron bomb) feature. It had an explosive yield of about 1 kt., was manufactured during 1981-83, and retired by 1992; 380 were built. Note that using the explosive yield of a neutron weapon to measure its destructive power can be deceptive: most of the injuries inflicted by a neutron weapon are caused by its intense pulse of ionising radiation, not from heat and blast.
The inventor of the neutron bomb, Samuel Cohen, has criticized the description of the W70 as a "neutron bomb" W70 Mod 3 warhead was dismantled in 1996.
W79 Mod Warhead
The W79 was produced in two models, the "W79 Mod 0" and "W79 Mod 1". Both were a plutonium-based linear-implosion, nuclear weapon. The "Mod 0" was a variable yield device with three yields, ranging from 100 tons up to 1.1 kiloton and an enhanced-radiation (popularly known as Neutron bomb) mode which could be turned on or off.
The "Mod 1" was fission only, without the enhanced-radiation option, and had a fixed 0.8 kiloton yield (800 tons of TNT). This probably corresponds with the maximum pure-fission yield of the "Mod 0".
Both models were 8 inches (203 mm) in diameter, 44 inches (112 cm) long and weighed 200 pounds (90 kg).
The W79 was produced in 1981 and continuing into 1986. All units were retired from active service by the end of 1992.
FATHER OF NEUTRON BOMB
Samuel T. Cohen, the physicist who invented the small tactical nuclear weapon known as the neutron bomb, a controversial device designed to kill enemy troops with subatomic particles but leave battlefields and cities relatively intact.
.
Samuel Theodore Cohen was born in Brooklyn on Jan. 25, 1921, to Lazarus and Jenny Cohen, Austrian Jews who had migrated to the United States by way of Britain. His father was a carpenter and his mother a housewife who rigidly controlled family diets and even breathing habits (believing it unhealthy to breathe through the mouth). The boy had allergies, eye problems and other ailments, and for years was subjected to daily ice-water showers to toughen him up.
The family moved to Los Angeles when he was 4. He was a brilliant student at public schools and U.C.L.A., where he graduated in 1943 with a physics degree. He joined the wartime Army and was posted to the Massachusetts Institute of Technology for advanced training in mathematics and physics.
In 1944 he was tapped for the Manhattan Project to analyze radioactivity in nuclear fission. He worked on Fat Man, the bomb dropped on Nagasaki in 1945, days after Little Boy destroyed Hiroshima.
Mr. Cohen was married twice. His first marriage, to Barbara Bissell in 1948, ended in divorce in 1952. In 1960, he married Margaret Munnemann. She survives him, as do their three children, Carla Nagler, Paul and Thomas, and three grandchildren.
Mr. Cohen joined RAND in Santa Monica in 1947 and 11 years later designed the neutron bomb as a consultant to the Lawrence Livermore National Laboratory. Many technical features of what the Pentagon called an “enhanced radiation weapon” had been known for years, and scientists had theorized about a nuclear device that would release most of its energy as radiation.
All nuclear explosions produce a rain of potentially lethal neutrons, uncharged particles from an atom’s nucleus, and Mr. Cohen, by adjusting components and reshaping the bomb shell, limited the blast and released more energy as neutrons — so tiny they passed easily through solid inanimate objects, but killed all living things in their path.
The military successfully tested the bomb, and over the next two decades Mr. Cohen campaigned for its deployment without success. He left RAND in 1969, but continued writing about the bomb. His articles appeared in The Washington Post, The New York Times, The Wall Street Journal and other publications. He was featured in a 1992 segment of the BBC-TV series “Pandora’s Box.”
His books included “Tactical Nuclear Weapons: An Examination of the Issues” (1978); “The Neutron Bomb: Political, Technological and Military Issues” (1978); “Checkmate on War” (1980); “The Truth About the Neutron Bomb” (1983); “We Can Prevent World War III” (1985); and “Nuclear Weapons, Policies and the Test Ban Issue” (1987). His memoir, “Shame: Confessions of the Father of the Neutron Bomb,” was published on the Internet in 2000.
In recent years, Mr. Cohen prominently warned of a black market substance called red mercury, supposedly capable of compressing fusion materials to detonate a nuclear device as small as a baseball — ideal for terrorists.
Most scientists call the substance mythical, and stories about it, many circulating on the Internet, are widely regarded as spurious.
Samuel T. Cohen died on Sunday at his home in Los Angeles. He was 89.
The cause was complications of stomach cancer, his son Paul said.
Unlike J. Robert Oppenheimer and Edward Teller, the respective fathers of the atomic and hydrogen bombs, Mr. Cohen was not well known outside government and scientific circles, although his work for years influenced the international debate over the deployment and potential uses of nuclear arms.
In contrast to strategic warheads, which can kill millions and level cities, and smaller short-range tactical nuclear arms designed to wipe out battlefield forces, the neutron bomb minimized blast and heat. Instead, it maximized a barrage of infinitesimal neutrons that could zip through tanks, buildings and other structures and kill people, usually by destroying the central nervous system, and all other life forms.
While doubters questioned the usefulness, logic and ethics of killing people and sparing property, Mr. Cohen called his bomb a “sane” and “moral” weapon that could limit death, destruction and radioactive contamination, killing combatants while leaving civilians and towns unscathed. He insisted that many critics misunderstood or purposely misrepresented his ideas for political, economic or mercenary reasons.
A specialist in the radiological effects of nuclear weapons, he relentlessly promoted the neutron bomb for much of his life, writing books and articles, conferring with presidents and cabinet officials, taking his case to Congressional committees, scientific bodies and international forums. He won many converts, but ultimately failed to persuade the United States to integrate the device into its tactical nuclear arsenal.
The Reagan administration developed but never deployed the weapons in the 1980s. France, Israel and the Soviet Union were believed to have added versions of the bomb to their arsenals. Western military planners rejected their use in the Vietnam War and regarded them only as a possible deterrent to superior Soviet tank forces in Europe. But the end of the cold war obviated even that purpose.
A graduate of the University of California, Los Angeles, Mr. Cohen was recruited while in the Army in World War II for the Manhattan Project, which developed the first atomic bomb at Los Alamos, N.M. After the war, he joined the RAND Corporation and in 1958 designed the neutron bomb as a way to strike a cluster of enemy forces while sparing infrastructure and distant civilian populations.
Fired via a missile or an artillery shell and detonated a quarter-mile above ground, his bomb limited death to an area less than a mile across, avoiding wider indiscriminate slaughter and destruction. It was not a radioactively “clean” bomb, but its neutrons dissipated quickly, leaving no long-term contamination that could render entire regions uninhabitable for decades.
But many military planners scoffed at the idea of a nuclear bomb that limited killing and destruction, and insisted that deployment would escalate the arms race and make nuclear war more likely. The device was anathema to military contractors and armed services with vested interests in nuclear arsenals. Even peace activists denounced it as “a capitalist weapon” because it killed people but spared the real estate.
Washington rejected the bomb repeatedly. The Kennedy administration said it might jeopardize a test-ban moratorium. The Johnson administration said its use in Vietnam might raise the specter of Hiroshima — Asians again slaughtered by American nuclear bombs — drawing worldwide condemnation. In 1978, President Jimmy Carter said development might impede disarmament prospects.
In 1981, President Ronald Reagan ordered 700 neutron warheads built to oppose Soviet tank forces in Europe. He called it “the first weapon that’s come along in a long time that could easily and economically alter the balance of power.” But deployment to the North Atlantic alliance was canceled after a storm of antinuclear protests across Europe. President George Bush ordered the stockpile scrapped.
By 1982, Mr. Cohen had abandoned his deployment quest. But he continued for the rest of his life to defend the bomb as practical and humane.
“It’s the most sane and moral weapon ever devised,” he said in September in a telephone interview for this obituary. “It’s the only nuclear weapon in history that makes sense in waging war. When the war is over, the world is still intact.”

Past interview of Cohen for the Tribune review :
Confessions of the Father of Neutron bomb
By Christopher Ruddy
With that and other battles lost, the 76-year-old Cohen finds solace in his Brentwood home, nestled high on a hill overlooking Los Angeles. There the world is far more peaceful, or so it seems. Just down the road is the Rockingham estate of one O.J. Simpson. Cohen would pass there often during his morning walks, and occasionally see the former football star. "He was always pleasant," Cohen recounted.
Cohen would probably be unfazed if confronted by a knife-wielding mugger - a threat insignificant in the scheme of things. What worries him are weapons of mass destruction - nuclear ones that destroy whole cities.
The politicians tell us that our security has never been better. Cohen describes the present situation as "scary, more scary than ever before." He's concerned that the Clinton administration has decided it is politically incorrect to even think about the design and development of nuclear weapons. The head of the division of the Livermore National Laboratories in charge of such weapon development has threatened to resign if he is ordered to develop new weapons, Cohen noted in a recent interview.
The government doesn't want people to even think about nuclear weapons, which is like telling Sam Cohen he is no longer permitted to breathe.
As a kid from Brooklyn who graduated with a physics degree from UCLA, he enlisted in the Army after Pearl Harbor. In 1944 Cohen was assigned to the top-secret Manhattan Project to develop atomic weapons at Los Alamos, N.M. Cohen had the mundane job of calculating how neutrons behaved in "Fat Man" - the nickname of the bomb dropped on Nagasaki. (The bomb dropped on Hiroshima three days earlier was nicknamed "Little Boy.")
The boring work was all worthwhile because Cohen eventually stood in the Nevada desert and witnessed something on par with the Transfiguration: an atomic explosion. Cohen saw firsthand the awesome power of the unleashed atom as human history entered a new age. "Awesome spectacle" is how Cohen still describes the event. Puffing on a cigar as he relaxed in his easy chair wearing a T-shirt and jogging pants, Sam remembered that day vividly.
World War II flying hero Jimmy Doolittle stood next to him when the bomb went off. "The little guy was blown down," Cohen recalled.
After the war ended, Cohen joined the Rand Corp. where he was paid to continue thinking about nuclear weapons. He was obsessed with the idea of a neutron bomb, one that would make use of the lethal particles he had observed so studiously at Los Alamos.
The earliest bombs had used nuclear fission, splitting heavy atoms to release energy. Later bombs used nuclear fusion, which fused hydrogen atoms to release energy. Both designs produced tremendous blasts that could level whole cities, and left them uninhabitable for long periods because of lingering radiation.
Cohen's neutron bomb would use nuclear fusion, but in a different way. The detonation of a neutron bomb would still produce an explosion, but one much smaller than a standard nuclear weapon's. The main effect of a neutron bomb would be the release of high-energy neutrons that would take lives far beyond the blast area. The result: fewer buildings, cars, tanks, roads, highways and other structures destroyed.
And unlike standard nuclear bombs that leave long-term contamination of the soil and infrastructure, the neutron radiation quickly dissipates after the explosion.
For Cohen, the neutron bomb is the ultimate sane weapon. It kills humans, or as he puts it "the bad guys," but doesn't produce tremendous collateral damage on civilian populations and the infrastructure a civilian population needs to survive.
This meant, in Cohen's mind, that a conventional war could escalate without immediately leading to an all-out nuclear holocaust. If regular nuclear weapons were used across Europe, the radioactive fallout could turn the continent into a wasteland for decades. That wouldn't be the case if neutron bombs were used.
Between 1958 and 1961 the neutron bomb idea was tested successfully, but the politicians in Washington nixed development and deployment of the weapon. Cohen persisted. As the Vietnam War began and festered in the 1960s, Cohen became an advocate of using neutron bombs there. To Cohen, his weapon was "a perfect fit" for dealing with the Viet Cong hidden in the jungles and rice paddies.
Again, the politicians had other ideas. Secretary of Defense Robert McNamara ruled that no nuclear weapons of any type would be used in the war. The use of the small neutron bombs would have brought the war to a quick end, Cohen still argues, and saved the loss of more than 50,000 American lives.
In 1969, Cohen was fired from the Rand Corp. for continuing to advocate the use of tactical neutron bombs to end the conflict. "I lost all my battles," Cohen says today.
In 1979, he was in Paris helping the French build their own arsenal of neutron bombs when presidential candidate Ronald Reagan came through on a European tour. Cohen met with Reagan to brief him on the neutron bomb. Reagan grasped the idea of neutron weaponry immediately, and made a pledge to Cohen, and later a public pledge, that he would reverse Carter administration policy by building and deploying a large number of neutron bombs.
As president, Reagan fulfilled that pledge and approximately a thousand weapons were constructed. But criticism from European allies kept the weapons from being deployed across Europe.
With the fall of the Berlin Wall and the end of communism as we knew it, the Bush administration moved to dismantle all of our tactical nuclear weapons, including the Reagan stockpile of neutron bombs. In Cohen's mind, America was brought back to Square One. Without tactical weapons like the neutron bomb, America would be left with two choices if an enemy was winning a conventional war: surrender, or unleash the holocaust of strategic nuclear weapons.
Other nation's haven't been afflicted by the U.S. blindness regarding neutron bombs. According to Cohen:
Evidence exists that China has neutron bombs stockpiled, and that the United States gave the Chinese the technology to build them.
Russia has a large quantity of such weapons, as well as the world's largest arsenal of nuclear weapons.
Israel has hundreds of neutron weapons. The neutron bombs would allow Israel to stop advancing Arab armies and tank columns - even one on Israeli soil - without permanently contaminating the land.
South Africa, which constructed a cache of neutron weapons before the end of white rule, claimed it dismantled those weapons before handing over power to the Nelson Mandela government. Cohen, however, claims to have it on good authority that white military leaders still control the secret stockpile as "an insurance policy."
Most frightening for Cohen is the relative ease by which neutron bombs can be created with a substance called red mercury. Red mercury is a compound containing mercury that has undergone massive irradiation. When exploded, it creates tremendous heat and pressure - the same type needed to trigger a fusion device such as a mini-neutron bomb.
Before, an obstacle to creating a nuclear bomb was the need for plutonium, which when exploded could create a fusion reaction in hydrogen atoms. But red mercury has changed that. The cheap substance has been produced in Russia, Cohen said, and shipped on the black market throughout the world.
Cohen said that when U.N. inspectors went to Iraq to examine the Iraqis' nuclear weapons capabilities, the U.N. team found documents showing that they had purchased quantities of red mercury. The material means a neutron bomb can be built "the size of baseball" but able to kill everyone within several square blocks.
The public isn't being warned about this development because the politicians have little desire to combat the menace or to confront nations like Iraq, Iran and Libya that likely would use such weapons, Cohen said.
Cohen has little faith in the politicians anyway. "Every president since Truman, with the possible exception of Eisenhower, would have sold the country out if it came down to a nuclear confrontation," he said.
Cohen on nation security issues
In a recent interview, Sam Cohen, the father of the neutron bomb, offered his views on several national security issues:
RUSSIA: Though the Cold War is over and Russia appears in disarray, Cohen suggested that the situation remains dangerous because Russia has "far and away substantially more nuclear weapons than we do." While U.S. policy makers have been busy dismantling our nuclear arsenal, Russia continues to modernize.
The United States has been paying billions of dollars for the leftover plutonium from Russia's dismantled weapons, but evidence indicates that the Russians have not been turning over weapons-grade plutonium. Instead, the United States has been paying for, and not objecting to, material from their nuclear power plants - a strong sign the Russians are not dismantling their weapons.
MISSILE DEFENSES: Calling a ballistic missile defense system "absolutely necessary," Cohen said American space-based plans so far have been a "debacle" that have cost taxpayers more than $50 billion.
Cohen argued that the "Star Wars" plan envisioned by President Ronald Reagan was inherently flawed. Politicians, once again fearing the "n" word, promised that nuclear weapons would not be used in any missile defense system. Cohen contends Reagan received misleading advice that technology was advanced enough to create a non-nuclear missile defense system.
Almost 15 years have passed since Reagan's call for a missile defense system, and still no weapons have been deployed. Cohen said that, had nuclear weapons been used, a fairly inexpensive system could already have been deployed. In such a system, nuclear weapons are exploded high in the atmosphere to either destroy or knock off trajectory incoming missiles. While the radioactive fallout from such explosions would pose some threat to civilian populations, it would be infinitely less harmful than having enemy missiles hit their targets.
Already, Cohen reported, the Russians have a sophisticated nuclear-based missile defense system around Moscow and possibly elsewhere. According to published intelligence reports, in the late 1980s the Russians began developing a "plasma weapon" for missile defenses. The plasma weapon uses nuclear energy to ionize the atmosphere, destroying or rendering inoperable any missiles passing through the plasma field.
SEAPOWER: Cohen said navies have become "obsolete" in terms of global warfare using nuclear weapons, and he described floating ships as "sitting ducks" for nuclear weapons. The U.S. Navy depends on AEGIS missile defense systems to protect its fleets, but Cohen said AEGIS has failed all of its tests, and there is no proof that it could fend off a multi-missile strike against a fleet, let alone a country.
Cohen said the U.S. Navy should put more resources into nuclear-powered submarines because of the difficulty any enemy might have in destroying them in a first strike.
For years, the nuclear submarines were the most important part of our deterrent against surprise nuclear attack, primarily because the submarine captain and crew did not need special codes, known as permissive action links or PALs, to fire their weapons. Thus, if a surprise attack disabled our military communications, the submarine could still counterattack.
In recent years, Cohen said, the Clinton administration has instituted the use of PALs on nuclear missile submarines, limiting their deterrence value.
CHINA: Cohen thinks China will soon be in position to blackmail the United States into reneging on promises to defend Taiwan. Already China has made overt threats about hitting the U.S. mainland with nuclear weapons. "China has said, `OK, if you defend Taiwan, we'll drop a nuclear weapon on Los Angeles,'" Cohen said.
In a trip to Taiwan, Cohen spoke before the military leadership there and strongly advised them to begin their own nuclear weapons program. The United States will not defend you because the politicians don't care about you, he told them.
