Length:
29 min-132 mb Movie Format: WMV (Windows Media Player)

Content: The program was established to explore the technical and economic feasibility of using nuclear explosions for civilian applications. Plowshare started with great expectations and high hopes. Between 1961 and 1973, 27 nuclear explosive Plowshare tests were conducted.
Possible excavation applications included: canals, harbours, highway and railroad cuts through mountains, construction of dams. Among them Sedan, a crater excavation experiment with a yield of 104 kt. Under the pressure of economical and environmental concerns the Plowhare Program was discontinued at 1975.

102-Sandstone-Hiroschima-Nagasaki

Length:
45 min, 227 mb Movie Format: WMV (Windows Media Player)

Content: 1948: The Sandstone test series introduced a second generation of weapon design by evaluating several new design principles. In addition a number of design parameters were varied to evaluate their effects on performance. The original Fat Man pit design used a Christy solid plutonium core, surrounded by a close fitting natural uranium tamper. The Sandstone devices all replaced the contiguous tamper-core approach with a "levitated core" in which the core was suspended within a larger hollow space within the tamper so that a gap existed between them. The collision between the tamper and core would create more efficient compression of the core than the explosive-driven shock in the wartime design. They apparently retained a solid core however. These devices also abandoned the use of a pure plutonium core since oralloy (uranium highly enriched in U-235) production exceeded plutonium production by a factor of over 3-to-1. The first test, X-Ray, used a composite oralloy-plutonium core. Both Yoke and Zebra used an all oralloy core. The pits (tamper plus core) for all three devices weighed about the same. Other tested features included: varying the tamper thickness (which had been fixed at 7 cm in earlier devices) varying the amount of fissile material in the core. The effect of using a "minimum strength" polonium-beryllium Urchin neutron initiator.

103-Operation Greenhouse, Castle

Length:
42 min, 279 mb Movie Format: WMV (Windows Media Player)

Content: The Greenhouse Test Series was conducted at Enewetok Atoll in April and May of 1951. It consisted of four relatively high yield tests (by the standards of the time) - Dog, Easy, George, and Item. Dog and Easy were proof tests of two new strategic bombs the Mk 6 and Mk 5 respectively. George and Item were the first true tests of thermonuclear fusion - the release of fusion energy from thermally excited nuclei. George was a research experiment that studied deuterium-fusion burning when heated by thermal radiation. Item was the first test of the principle of fusion boosting of fission devices.
Castle Bravo: The first thermonuclear test yielded 15 MT, twice the predicted yield.

104-Operation Argus

Length:
44 min, 218 mb Movie Format: WMV (Windows Media Player)

Content: 1958: Operation Argus was the only clandestine test series in the 17-year history of atmospheric testing. It was secretly conducted in the South Atlantic, 1100 miles southwest of Cape town, South Africa. Argus consisted of three very high altitude test shots of the W-25 warhead to investigate the effects of nuclear explosions outside of the atmosphere - how the charged particles and radioactive isotopes released would interact with the Earth's magnetic field which could potentially interfere with radar tracking, communications, and the electronics of satellites and ballistic missiles.

In a way, these tests could be considered a logical extension of the high altitude shots conducted within the atmosphere in Hardtack I, which detonated warheads at 85,250 feet (a 1.7 kt W-25 in the Yucca shot), 141,000 feet (a 3.8 Mt W-39 in the Orange shot), and 252,000 feet (also a 3.8 Mt W-39 in the Teak shot). Argus pushed nuclear tests still higher with effects tests at 100 miles (528,000 feet), 182 miles (961,000 feet), and 466 miles (2,460,000 feet).
The motivation for this secret series was a theory developed by the brilliant but eccentric physicist Nicholas Christofilos at Lawrence Radiation Laboratory (LRL). He had predicted that injecting charged particles from nuclear explosions into near space to create artificial Van Allen belts would produce military significant effects. This series sought to prove (or disprove) his theory by actually creating such a belt. Operation Argus has been termed the "world's largest scientific experiment" encompassing as it did the space surrounding the entire Earth. The tests essentially confirmed his predictions.

This $200 million 1971 test was performed to test an Anti-Ballistic Missile warhead, for a Spartan ABM missile. It consisted of a 5 megaton-yield thermonuclear bomb, detonated in a 50-foot diameter chamber, at the bottom of a 5,875-foot shaft. The island of Amchitka was a military outpost in WWII, and the air field and base camp from that facility were reused for the nuclear testing programm.

Content: 1956: The lab tests centred on ICBM and SLBM missile warheads and high yield strategic bombs. The DOD conducted high altitude multi-megaton tests to study their usefulness for ABM (anti-ballistic missile) warheads, and discovered the high-altitude EMP (electromagnetic pulse) effect in the process. Effects tests of underwater explosions were also conducted.
At least 14 mark-designated warheads were tested This series fired the largest tests since Ivy and Castle and led to the development and deployment of the largest U.S. weapon ever fielded, the 25 Mt Mk-41 bomb. The UCRL test of the W-47 Polaris warhead prototype was a major technological breakthrough that led to high yields in small light packages characteristic of all U.S. missile warheads today.
The extensive test schedule required the use not only of both atolls (Bikini and Enewetak) but Johnston Island also. This series was the last to conduct atmospheric testing at Bikini and Enewetak atolls.

Content: 30 kt, 2000ft depth. Operation Wigwam consisted of a single nuclear detonation, (both the operation and test are known as Wigwam), conducted 400-500 miles SW of San Diego, California(about 29 Deg N, 126 Deg W). It was a deep water test (the ocean is 16,000 feet deep at that point) to investigate the vulnerability of submarines to deep nuclear weapons, and the feasibility of using depth bombs in combat (there was considerable concern about problems with surface contamination). The test device was a B-7 (Mk-90) Betty depth bomb that was suspended by a 2000 ft cable from a barge. The dry weight of the bomb was 8250 lb, 5700 lb when submerged.
6800 personnel on 30 ships participated in Wigwam. A 6 mile tow-line connected the fleet tug, Tawasa and the shot barge. Suspended from this line at varying ditances from the barge were three "Squaws" - sub-scale submarine-like pressure hulls equipped with instruments and cameras. The ships conducting the test were 5 miles upwind from the barge, with the exception of the USS George Eastman (YAG-39) and USS Granville S. Hall (YAG-40). These two ships were equipped with heavy shielding and were stationed 5 miles downwind. Both ships were contaminated by the base surge, but due to the relatively dilute radioactivity (since the shot was at such a great depth) and the heavy shielding kept exposures within the Operation Wigwam dose limit of 3.9 rems. Nearly all personnel were issued film badges to measure radiation exposure, and some 10,000 badges were processed. Only 3 personnel were measured as having doses exceeding 0.5 rems.

Content: One of three underground nuclear tests performed at different places on this 43-mile long island in the Aleutian Chain. This 1969 test, named Milrow, consisted of an 1.2 megaton-yield bomb, detonated at the bottom of a 3,990-foot shaft. The test was part of a calibration program conducted to measure the island's responses to high-yield nuclear tests, in anticipation of another, larger test, code-named Cannikin. The island of Amchitka was a military outpost in WWII, and the air field and base camp from that facility were reused for the nuclear testing program. Location: 1400 miles west of anchorage, Amchitka Island
Long shot: This 1965 test consisted of an 85 kiloton yield bomb, detonated at the bottom of a 2,359-foot shaft. The test was one of several in a series, performed at various locations, to calibrate detection equipment for monitoring the Russian nuclear testing program.

110-Operation Teapot

Length:
30 min, 161 mb Movie Format: WMV (Windows Media Player)

Content: 1955. This series of fourteen shots proof tested a broad variety of fission devices with low to moderate yields. As a group these devices combined several innovations - some previously tested, some introduced during this test series - to create a new pattern of fission device that would dominate the design of all later weapons. These devices used new compact, efficient, light weight spherical implosion systems; beryllium tampers; hollow cores; deuterium-tritium boosting; and the use of neutron pulse tubes as initiators to create light, compact, efficient, and reliable fission explosive systems.
Several new primaries were tested for a new generation of lighter and more compact thermonuclear weapons to be fired in 1956 during Operation Redwing.
Weapons effects tests were scheduled to develop information on the use of nuclear explosives against aircraft, and to gain more information about cratering.
Approximately 8000 DOD personnel participated in the Desert Rock VI exercise, which was intended to familiarize troops with the capabilities of nuclear weapons, and the conditions of atomic combat.

Content: In late 1951 two test series were held together for the first time - Operation Buster (conducted by Los Alamos) and Operation Jangle (conducted by the DOD). 7800 DOD personnel participated in Buster-Jangle, 6500 of them troops who conducted field exercises in conjunction with the tests. These were the first such field exercises conducted in the United States proper.
Buster-Jangle was held at the Nevada Proving Ground (later NTS) and had a number of objectives. The first drop from a Jet Plane, the B 45. The Buster series was primarily a weapon development effort. A number of pit configurations were fired in an Mk-4 high explosive assembly to collect data for weapons design. In addition the TX-7E design was proof fired (leading to the deployment of the Mk7 light weight bomb). The Jangle series evaluated the usefulness of atomic weapons in cratering using ground level and sub-surface bursts. The Desert Rock II and III troop exercises were held in conjunction with these tests. The purpose of the Desert Rock exercises was to gain experience in operations Conducted in a nuclear combat environment

Content: 1952: Enewetak-Atoll, Pazifik: At that time, the highest priority was placed on developing new and more potent strategic weapons - especially thermonuclear weapons (hydrogen bombs). No one had good ideas about how a practical thermonuclear weapon could be made. This raised new fears - that Truman's pronouncement may have surred Soviet thermonuclear efforts onward even faster, and that they might have hit upon concepts not yet known in the U.S. Consequently a fallback strategy was pursued - developing the highest yield fission bomb possible, a technical effort led by Theodore Taylor at Los Alamos. The conceptual breakthroughs of Stanslaw Ulam and Edward Teller the following January provided the needed insights to develop a thermonuclear device.
So from early 1951 onward, these two parallel efforts to develop high yield weapons were focused on a Pacific Proving Ground test series for late in 1952. This series - Operation Ivy - exploded the two largest bombs tested up to that time. It inaugurated the thermonuclear age with the first "true" thermonuclear test (code name Mike), which was considerably more powerful than all the high explosives used in two World Wars put together. Ivy also tested the highest yield pure fission weapon ever exploded.

114-Upshot-Knothole

Length:
35 min, 186 mb Movie Format: WMV (Windows Media Player)

Content: Upshot knothole 1953, Nevada
By 1953 a pattern of test activity at the Nevada Proving Ground had emerged. Through the fifties, every year or (every other year if a pacific test series intervened) a series of several shots was fired at the NPG over a period of three or four months to address a wide variety of objectives. Upshot-Knothole was just such a scatter-shot effort. Technical information to assist in weapon design was obtained in several tests. Efforts to prepare the U.S. military for atomic combat continued with proof-tests of a number of new tactical weapons, including the first nuclear artillery shell. The tests provided additional experience and information for planning atomic combat operations. Important information was also obtained for civil defence efforts. Grable: A 280mm canon fired the first nuclear projectile. The yield was 15kt. After little boy this was only the second and also the last gun type device used.
And critically important - Upshot-Knothole also tested the radiation implosion systems for the world's first deployable thermonuclear weapons, which would be proof-tested in Operation Castle the following year.
An estimated 18,000 DOD personnel participated in observer programs, tactical manoeuvres, scientific studies, and support activities. Members of all four armed services participated in Exercise Desert Rock V.
This operation exposed exercise personnel to nuclear tests, and thus radiation, more aggressively than previous ones. Observation by troop formations was conducted at what was calculated to be the minimum safe separation distance, with many personnel being exposed to multiple tests. Under current occupational radiation exposure limits (0.3 rem/week and 5 rem/year) this would limit maximum exposures to 3.3 rems over the 11-week operation. Approximately three thousand soldiers reached or exceeded this limit, with 84 exceeding the annual limit (the highest recorded exposure was 26.6 rem). These exposures do not produce observable symptoms; they simply increase the lifetime risk of cancer a small amount.

Content: 1956: Redwing was the second U.S. test series devoted primarily to proving thermonuclear designs of actual weapons. It centred on testing a broad variety of new innovative second generation designs. Redwing was conducted under an "energy budget" - the total explosive yield of the series, and the total fission yield were both assigned fixed limits for the whole series. The total yield limit was approximately 20 megatons.
Due to the extensive roster of megaton range tests scheduled for Redwing both Bikini and Enewetak atolls were used to make the shot schedule more tractable.
This series proof tested the Mk-28 warhead, a lightweight, small diameter thermonuclear design (20 inch diameter) dramatically smaller than most of the Castle designs; and "salted" or "dirty" (extremely high fall-out) weapons. Tests of low yield tactical fission weapons were also conducted, including some very small diameter, lightweight systems (diameters of 5, 8, and 11.6 inches). The first U.S. airdrop of a thermonuclear weapon was also conducted - partly as a weapons effects test, and partly as a political demonstration of the United States' capability to conduct nuclear attacks.

Content: 1957 Nevada
Operation Plumbbob was conducted at the Nevada Test Site (NTS) from May through October of 1957. It was the sixth test series at NTS and consisted of 29 tests. Six of these were safety tests, and two did not produce any nuclear yield. This series addressed several objectives, including tactical weapon proof tests, safety tests, and component and mock-up testing for thermonuclear systems to be detonated in Hardtack I, among other things.
Priscilla, 700ft balloon shot with 37kt. A bank vault was among several other test objectives.
During Plumbbob 16,000 DOD personnel participated in the Desert Rock VII and VIII exercises.
Plumbbob released some 58,300 kilocuries of radio iodine (I-131) into the atmosphere. This was more than twice as much as any other continental test series. This produced total civilian radiation exposures amounting to 120 million person-rads of thyroid tissue exposure (about 32% of all exposure due to continental nuclear tests).

118-Hardtack 2

Length:
24 min, 105 mb Movie Format: WMV (Windows Media Player)

Content: Hardtack II included 37 tests, the largest test series so far, exceeding the 35 tests of the just completed Hardtack I.
Most of the tests were efforts to prove the safety and effectiveness of new "sealed pit" fission primaries and tactical weapons. This task proved extremely difficult, caught between the Scylla of safety (ensuring that accidental detonation of the explosive could not create even a small nuclear yield) and the Charybdis of effectiveness (ensuring that the weapon reached its design yield). Effective designs often proved unsafe, and modifications made to achieve safety often led to fizzles. As a result, despite the large number of tests, only a fairly small number of application systems were actually under development. For example, at least 10 shots were conducted to verify the safety and effectiveness of a primary for the XW-54 warhead. No more than 7 design types account for at least 29 of the tests. This series included tests of what is probably the lightest nuclear system feasible - the XW-51 Davy Crockett warhead - weighing only 16 kg in its tested form.

The world's first underground nuclear test had been fired in the previous NTS series (Plumbbob Rainier), and this series introduced underground testing as a routine procedure. The intention was to reduce the fallout effects of the testing, which were raising great concern, but the "underground" testing procedures were still relatively primitive. Many of these shots were conducted in "unstemmed" holes, that is, holes not back-filled and sealed prior to testing. These shots were called "roman candles" since the incandescent gas from the fireball was ejected as a jet from the mouth of the shaft. Obviously fallout containment was much less than perfect, but most of the fission product was nonetheless deposited in the shaft instead of escaping, and the radiation that did escape was not lofted so that it could not travel far downwind.

119-Vela Uniform

Length:
21 min, 125 mb Movie Format: WMV (Windows Media Player)

Content: Operation Nougat included a total of 44 shots, including a Seismic Detection Program, 1961-Gnome, a 3-kiloton multipurpose test conducted in an underground salt bed deposit near Carlsbad, New Mexico. This series was conducted at the Nevada Test Site, which permitted rapid initiation of tests, but restricted them to low yields (and mostly underground test shots) due to fallout concerns. Although this was still the "era of atmospheric testing", Nougat was actually the first underground test series. Higher yield atmospheric tests followed seven months later with Operation Dominic in the Pacific. Nougat included a total of 44 shots, exceeding the previous record holder, Operation Hardtack II, with 37 tests.
Nougat generally resembles Hardtack II in the nature of testing that was conducted. Low yield tactical devices were extensively tested. Thermonuclear primaries and radiation implosion mock-ups were tested. Much attention was paid to simultaneously achieving desired performance and one-point safety in "sealed pit" fission devices, some designs requiring numerous shots. Since all the tests were fired underground, and only a few of them produced true blast craters (i.e. not subsidence craters caused by blast cavity collapse), there are few pictures available of these tests.

Content: Operation Plowshare was the overall American term for the development of techniques to use nuclear explosives for peaceful construction purposes.
Proposed uses included widening the Panama Canal, constructing a new waterway through Nicaragua, cutting paths through mountainous areas for highways, and mining. More speculative uses included setting nuclear weapons off in underground caverns with the hope of creating steam which could then be used to generate electricity (tests indicated that the steam would be too radioactive for safe use, however). The plowshares operations which was closes to being carried out was the the planned Chariot blast which would use hydrogen bombs to create an artificial harbor at Cape Thompson, Alaska. It was never carried out due to concerns for the native populations and the fact that there little potential use for the harbor which would justify its risk and expense.
The use of nuclear weapons for civilian engineering purposes has never been applied in the United States, but it has been tested. These twenty-eight shots were conducted in conjunction with other, weapons-related, test series.

Content: 1962, Christmas Island
The Soviet Union had abrogated the 34 month old de facto nuclear testing moratorium on 1 September 1961 by initiating an unprecedented series of atmospheric nuclear tests. The initial U.S. response was to commence its own test series (Operation Nougat) two weeks later. Nougat was an underground series however, restricted to very low yield devices.

Numerous atmospheric tests, many at high yield, were of course on the drawing board at the weapons labs, some carried over from planning for previous test series. Official U.S. action on convening its own atmospheric series did not begin until 10 October 1961 when President Kennedy approved planning for one. Final approval was given on 2 March 1962, 7 weeks in advance of the first planned test. Over 28000 man were involved.military and civilian. 200000 tons of material were shipped.

Dominic included 36 tests. The majority of the tests (29 airdrops) were weapons development tests, intended to evaluate advanced designs that the labs had been cooking up during the years of the moratorium and before. Five rocket-launched tests were conducted to gather further weapons effects data on high-altitude phenomena. Two tests of operational weapon systems were conducted - the Polaris submarine launched ballistic missile and the ASROC anti-submarine rocket.

Conducted as part of Operation Dominic was a series of high altitude tests known as Operation Fishbowl. These tests were Thor missile launched warheads detonated at very high altitudes (30-248 miles) to evaluate the destructive mechanisms and effects of high yield explosions against ballistic missile RVs. Several test failures occurred with missiles being destroyed in flight by range safety officers when electronics failed (Bluegill), when rocket motors malfunctioned (Starfish and Bluegill Prime), or when the missile veered out of control (Bluegill Double Prime). The Bluegill Prime test was particularly disastrous since the missile was blown up while still on the launch pad, requiring complete reconstruction of the demolished and plutonium contaminated Thor launch facility.
