Santa Fe
Balloon shot (460m)
Similar to devices fired in many of the preceding Hardtack II shots. Based on device characteristics - 11.3 inches in diameter, 15 inches long, weight 57.3 lb. - it was probably another XW-54/Gnat attempt. Yield below predictions.

Smoky
Test of the UCRL TX-41 thermonuclear design.

Franklin Prime
LASL retest of the fizzled Franklin device but with more U-235 added to the gas boosted all-oralloy implosion core. Predicted yield 2 kt. This was a development test of the XW-30 warhead. The Franklin device was enlarged, its diameter increasing from 20.8" to 21.4", and its length increasing from 38.4" to 45.8 in. More oralloy was added to the core. In addition, the combination of PBX 9401 and PBX 9404 used in the device was replaced by a combination of PBX 9010 and PBX 9404. The nuclear system weight was 304 lb.

Doppler
Ballon shot (460m)
ASL gas boosted implosion device, possible XW-34 test. Satisfactory performance. Device dimensions: diameter 17 inches, length 26 inches. Nuclear system weight 144.6 lb, total device weight 275 lb.

Shasta
This was a UCRL developmental test of a two stage thermonuclear design. A DT gas boosted Swan primary was fired in a mockup of the thermonuclear system. Shasta was nearly identical to Diablo, except for changes in case materials and pit geometry. Predicted yield was 11-15 kt. Device dimensions were 16.9 inches in diameter and 69.2 inches long. Total device weight was 1435 lb.

Stokes
Test of the LASL XW-30 multi-purpose warhead; used in TADM (tactical atomic demolition munition), and Talos SAM (surface-air-missile) warhead. All oralloy (highly enriched uranium) DT gas-boosted system. Predicted yield 10-20 kt. Device diameter 22 inches, length 45.8 inches. Nuclear system weight 317 lb., total device weight 448 lb.

Owens
Operation Plumbob
Very small boosted plutonium device, XW-51 progenitor.

Kepler
LASL ICBM warhead development test. Probable test of XW-35 primary in thermonuclear mockup. Similar to Hardtack I Koa device (which was tested at 1.37 Mt in 1958). Kepler had a predicted yield of 11 kt. The device had a diameter of 28.5 inches, and a length of 44 inches. The primary weighed 64.4 lb, the total device weight was 1517 lb.

John
Rocket (9140m)
Operation Plumbob
This was a combination proof test of the Genie (AIR-2A) nuclear air-to-air rocket, and an effects test of the Genie W-25 warhead. The unguided Genie rocket was fired from a F-89J. The rocket travelled 4240 meters in 4.5 seconds (about Mach 3) after release before detonating. The predicted yield was 1.7 kt. The plutonium core W-25 (probably with a depleted uranium tamper) had a diameter of 17.35 inches, a length of 25.74 inches, and weighed 221 lb.

Diablo
Tower shot
This was a UCRL developmental test of a two stage thermonuclear design. A boosted Swan primary was fired in a mockup of the thermonuclear system. The predicted yield was 11-15 kt, the secondary stage contributed to the total yield. This device was very similar to the Shasta test device. A full yield test of this device was intended for Hardtack I in 1958, and it may be related to the similarly dimensioned Hardtack I Cedar device which produced 220 kt. The diameter of this device was 16.2 inches, length 68.4 inches, and its total weight was 1352 lb.

Hood
Operation Plumbob
Hood was the largest atmospheric test ever conducted at NTS (and in continental U.S.). This was a test of a two-stage thermonuclear device designed by UCRL (University of California Radiation Laboratory), even though the U.S. government stated at the time that no thermonuclear tests were being conducted in Nevada. The design was intended to fill a gap in 300-400 lb. thermonuclear warhead technology, and was tested at reduced yield. The predicted yield was 60-80 kt. The device used a boosted Swan primary (which gave yields of 12-19 kt in other tests during Plumbbob). About 7 kt of the overall yield was from fusion. The device was a small diameter system (12.1 inches) and was 42.2 inches long. Total device weight was 393 lb. The test also included troop maneuvers by 2500 Marines, and air operations by 124 aircraft.

Priscilla
Priscilla was a weapons effects test sponsored by the DOD using a stockpiled device of known yield. The device used was a LASL designed Mk-15/39 boosted primary similar to that tested in Redwing Lacrosse. The predicted yield was 40 kt, the same as in the Lacrosse test, but the actual yield was slightly lower. The test device weighed 581.4 lb total (nuclear system weight was 542 lb). It was 27.1 inches in diameter, and was 27.1 inches long.

Wilson
XW-45X1 Swan test, gas-boosted composite pit.

Lassen
.5 tons (fizzle)
Fizzle, unboosted all-oralloy small weapon design.

Franklin
This LASL test was a fizzle, yielding only 7% of its predicted 2 kt yield. This was a test of the XW-30 warhead. The device was a boosted all-oralloy fission design. The diameter of the device was 20.8 inches, length 38.4 inches, and the nuclear system weight was 303.8 lb (total device weight 448 lb). A modified and enlarged version with more fissile material in the core and a different combination of high explosives was successfully retested in Franklin Prime.
http://www.nv.doe.gov/library/photos/photodetails.aspx?ID=63

Boltzmann
XW-40 light weight boosted fission warhead test. The device, developed by Los Alamos Scientific Laboratory (LASL), weighed 295 lb (total weight), the nuclear system by itself weighed 144.6 lb. Device width 18 inches, length 31.6 inches. The shot cab held 9 tons of sand, and 15 tons of paraffin as instrument shielding. Predicted yield was 11 kt.

Project 56 No. 4
Very small yield
Operation Project 56
Like shot No. 3 this was a one-point safety test for the prototype TX/W-28 primary. The device was basically identical except that 6 zippers were used as neutron sources.
The enhanced yield (compared to No. 3) was probably due to the larger neutron population injected into the core. Due to the low rate of neutron multiplication possible in this slightly supercritical system, only a limited amount of neutron multiplication is possible while the core remains compressed. A larger initial neutron population results in a larger final neutron population (and thus total fission output).
http://nuclearweaponarchive.org/Usa/Tests/Wigwam.html

Project 56 No. 3
Zero yield
Operation Project 56
This was a one-point safety test for the prototype TX/W-28 primary. The 16.8 inch diameter nuclear system weighed 143 lb, the total device weighed 275 lb. 3 zippers were used as neutron sources.
http://nuclearweaponarchive.org/Usa/Tests/Wigwam.html

Project 56 No. 2
Zero yield
One-point safety test of the plutonium containing W-25 sealed pit weapon. The device was 17.4 inches in diameter, 26.6 inches long, and weighed 218 lb. 3 zippers were used as neutron sources.
http://nuclearweaponarchive.org/Usa/Tests/Wigwam.html

One-point safety test of an all-oralloy prototype sealed pit weapon that was similar to the Plumbbob Priscilla and Redwing Lacrosse devices (tested at 37 and 40 kt respectively), probably the primary for the TX-15/39 and W-27.
To ensure safety of the deployed design, two changes were made to enhance the nuclear output of this test. More oralloy was used than would be present in the war-reserve model. Also 3 external neutron sources ("zippers") were used to ensure a large neutron population at the moment of criticality. The 37.1 inch diameter device weighed 600 lb.

Zucchini
Operation Teapot
This device was another LASL test of a Class "D" thermonuclear bomb primary/secondary system. This was a light case design, presumably using an aluminum case lined with a x-ray opaque high atomic number material (like lead or uranium). The device was 40 inches in diameter, 80.5 inches long, and weighed 2925 lb. Predicted yield was 40 kt.
http://nuclearweaponarchive.org/Usa/Tests/Teapot.html

Operation Teapot
This was a repeat of the LASL Apple-1 shot that had an inadequate yield. This shot used a modified device (presumably with more fissile material). Predicted yield was again 40 kt. Although this device still had a yield below predictions, it was twice the Apple-1 shot and apparently was adequate.
http://nuclearweaponarchive.org/Usa/Tests/Teapot.html

MET
MET stands either for "Military Effects Test" or "Military Effects Tower" (according to Frank Shelton). This was a LASL test of a composite U-233/plutonium bomb core (the first test by the U.S. to use U-233) in a Mk 7 HE assembly. The 30 inch diameter spherical implosion system weighed 800 lb.
The primary purpose was to evaluate the destructive effects of nuclear explosions for military purposes. For this reason, the DOD specified that a device must be used that had a yield calibrated to within +/- 10%, and the Buster Easy device design was selected (this test gave 31 kt and used a plutonium/U-235 core). LASL weapon designers however decided to conduct a weapon design experiment with this shot, and unbeknownst to the test effect personnel substituted the untried U-233 core. The predicted yield was 33 kt. The actual 22 kt was 33% below this, seriously compromising the data collected.

Post
This was a test of Cleo II, the second UCRL linear implosion device. 34.2 inches long, weight 322 lb. Used Cyclotol 75/25 HE. ENS initiated.

HA (High Altitude)
Airdrop (11160m)
This B-36H airdrop was a LASL high-altitude (= HA) test of an air-to-air missile warhead. Similar to the Wasp Prime device (17 inch spherical system weighing 125 lb) in a 1085 lb Mk-5 ballistic case. Due to the extreme high altitude of this test (for an air dropped device) it was parachute retarded to permit the release aircraft to escape to a safe distance, the only parachute weapon drop ever conducted at the NTS.

Wasp Prime
Airdrop (230m)
This was a repeat LASL test of the Wasp design, using a higher yield core for weapons development purposes, but otherwise identical. B-36 airdrop. The yield was about the same as predicted. As a minor footnote - this shot was fired 5 hours and 5 minutes after Apple-1, the first time in U.S. history that two nuclear explosions were set off in one day.

LASL test of a Class "D" (light weight) thermonuclear weapon primary and radiation implosion system, using small quantities of fusion fuel. The primary failed, yielding much less than the predicted 40 kt. No reaction was detected in the secondary stage. The nuclear system was 29.5 inches wide and 74.6 inches long and weighed 2300 lb.

Bee
This was a LASL test of a sealed-pit D-T gas boosted XW-25 air defense warhead. The maximum expected yield was 20 kt. It used a ZIPPER external initiator. The nuclear system weighed 130 lb and was a sphere 17 inches in diameter, the smallest and lightest device yet fired.

Hornet
4kt
This was a LASL test of the boosted version of the XW-30 air defense warhead. It was a sealed-pit D-T gas boosted design. The maximum expected yield was 10 kt. It used a ZIPPER external initiator. Total device weight was 500 lb, the nuclear system weighed 460 lb.

Turk
This was a UCRL test of a primary for the XW-27 Class "D" (light weight) thermonuclear weapon. The device, named LINDA, was a mockup of the XW-27 radiation case and was 30.5 inches by 61.3 inches and weighed 2325 lb. Expected yield was 45 kt.

Tesla
Tower (90m)
This was a UCRL linear implosion device named Cleo I. This was also the first successful UCRL test. It used a ZIPPER external neutron initiator. Predicted yield was 3.5-7 kt. The explosive used was Cyclotol 75/25. The nuclear system was a small diameter system only 10 inches wide and 39.5 inches long and weighed 785 lb.

Moth
This was a LASL proof test of the unboosted XW-30 fission air defense warhead. The total device weight was 445 lb (the lightest complete fission device yet fired), the actual nuclear system was 23 inches in diameter and weighed 375 lb. This was the first test to use an ENS (external neutron source) initiator - a compact pulse neutron tube. Predicted yield was 4 kt.

Wasp
Airdrop (230m)
Operation Teapod
This B-36 airdrop was a LASL air defense oriented weapons effects test, using the venerable Ranger Able uranium core in a new compact, light weight implosion system. The implosion system was a sphere 22 inches in diameter but only weighed 120 lb (!). It was dropped in a Mk-12 bomb case. This was the fifth time the Ranger Able core design had been used in a test. This test evaluated the effects of low altitude detonations. The total device weight was 1500 lb. Although the bomb was much heavier, the implosion system was the lightest nuclear explosive system fired up until this time (broken the following year during Operation Redwing).

Harry
Operation Upshot-Knothole
Most efficient pure fission design below 100 kt ever detonated.
Heaviest contamination of civilians downwind of any US continental test.
http://nuclearweaponarchive.org/Usa/Tests/Upshotk.html

Encore
B-50 bomber air drop from a height of 19,000 feet, the detonation was 15 feet west and 937 feet south of the designated ground zero. This was a weapon effects test ("E" as in "Encore" and "effects"), and used a Mk-6D bomb with a predicted yield of 30-35 kt. The total device weight was 8330 lb.

Simon
This was a test geared toward developing the TX-17/24 thermonuclear weapon design. The TX-17 and TX-24 were the physically largest and heaviest weapons, as well as one of the highest yield weapons, ever deployed by the United States. The test device, code named Simultaneity, was much smaller and lighter however. It had a diameter of 35.4 inches and a length of 224 inches, with a total weight of 11,000 lb (5000 kg). It used a redesigned RACER primary with 2 kg of enriched uranium added to the design tested in Nancy. This addition boosted its yield by almost a factor of two. The predicted yield was 35-40 kt.

Badger
This was a test of the TX-16 thermonuclear weapon design, the reduced size cryogenic weapon descended from the Sausage device tested in Ivy Mike. The test device was named Buzzard and used a deuterium gas boosted RACER primary. The expected yield was 35-40 kt. The device had a diameter of 56 inches, and weighed 7400 lb. The full scale thermonuclear version of this design was actually deployed on a limited scale for a short time as an "Emergency Capability" weapon in late 1953 and early 1954. The full scale version was never tested though due to the success of solid fueled weapon designs.

Ray
This was the second test of a uranium hydride device, this time using the heavy isotope of hydrogen - deuterium. The uranium deuteride device was called Hydride II, and was otherwise basically identical to Hydride I. The predicted yield was 0.5-1 kt, the lower expected yield making a smaller gap with the same 200 ton yield as the first test. UCRL scientist Herbert York claims not to regard this test as a failure since it was lower than the predicted range by "only a factor of three". Legend has it that this shot was fired on a tower of only 100 feet (compared to 300 feet for Ruth) to ensure that the tower would be entirely destroyed.

Dixie
B-50 bomber air drop, the detonation was 565 feet east, and 72 feet north of the designated ground zero. Dixie was a Mk-5D bomb proof test. The predicted yield was 8-12 kt. This test experimented with lithium deuteride as a means of fusion boosting. The device weight was 3260 lb, diameter was 60 inches, length was 128 inches.

Ruth

Nancy
This was a test of the TX-15 "Zombie" thermonuclear weapon design scheduled to be proof-tested at the Pacific Proving Grounds in 1954. The device, code named Nevada Zombie, tested both the RACER primary and the TX-15 radiation implosion system. The TX-15 appears to have been something of a transitional design between a radiation implosion fission bomb, and a optimized thermonuclear design. It was originally conceived as a two stage pure fission bomb using enriched uranium fuel, but matured into a thermonuclear system for improved yield as work progressed. It was lighter and had a smaller diameter than any of the other thermonuclear designs then under development. The Nevada Zombie weighed 11,000 lb., had a diameter of 35.4 inches, and a length of 122 inches. The RACER primary produced a yield below the predicted range of 35-40 kt, leading to a design modification for the Simon shot.

Annie
In an effort to calm public fears about weapons testing, Annie was an "open shot" - civilian reporters were permitted to view it from News Nob, 11 kilometers south of the shot-tower. Annie was a weapon development test, it was an experimental device (code named XR3) that provided additional information to normalize the yield-vs-initiation time curve. It was a Mk-5 HE assembly using a Type D pit, and used a betatron for external initiation (the third such test). Total device weight was 2700 lb, predicted yield was 15-20 kt.

How
Operation Snapper
This device (code named Scorpion) was designed in part by Ted Taylor. Snapper How was the first test to use a beryllium neutron reflector/tamper, which would become standard in later weapons. The test device used the same 22 inch implosion system as Snapper Easy, but the lightweight tamper cut 80 pounds off the implosion system weight. Predicted yield was 11 kt.

George
Operation Snapper
This device (code named XR2) used a Mk 5 bomb assembly. The test was intended to gather additional data on the initiation time vs yield curve. A novel feature of this test was the use of an external initiator - in this case employing a device called a betatron (which is a circular electron accelerator). In this test the high energy electrons were used to generate high energy X-rays that induced photo-fission in the core to initiate the chain reaction. The betatron allowed very accurate control of initiation time. The test device had a diameter of 40 inches and weighed 2700 lb, the predicted yield was 30 kt.

Fox
Operation Snapper
This device (code named XR1) used a Mk 5 bomb assembly. The test was intended to gather data on the initiation time vs yield curve; it also served as a calibration test of the TOM polonium-beryllium internal neutron initiator. The test device had a diameter of 40 inches and weighed 2700 lb, the predicted yield was 15-18 kt.

Easy
This device (code named BROK-1) was a test of the TX-12, a Mk-12 bomb prototype. The Mk-12 was intended to be a slender, lightweight tactical bomb that could be carried externally by high speed fighter-bombers. It set a record at the time for small diameter and light weight, with an implosion system diameter of 22 inches weighing only 550 lb (a modest improvement over the Mk-7), yet retained good compression and efficiency. The total device weight was 625 lb, with a predicted yield of 9 kt.

Dog
Dog was a test of a modified TX-7 weapon (previously tested in Buster Easy). The device tested the usefulness of deuterium gas fusion boosting (not deuterium-tritium boosting!). The predicted yield was 15-20 kt.

Charlie
Operation Tumbler
This test combined a proof test of a new high-efficiency core with blast effects measurements. The predicted yield was 40-60 kt. This test was broadcast live on television (a first). The Mk 4 based test device weighed 10,440 lb.

Baker
Operation Tumbler
This device also used the Ranger Able U-235 core in a Mk 4 based test device (weight 10,500 lb).

Able
Operation Tumbler
This device used the same U-235 core design first tested in Ranger Able. This design had become something of an experimental benchmark due to its convenient low yield and high predictability, having also been used in Jangle Sugar and Jangle Uncle. The Mk 4 based test device weighed 10,800 lb.

Sugar
Operation Jangle
http://nuclearweaponarchive.org/Usa/Tests/Busterj.html

Easy
Operation Buster
This was a test of the TX-7E , a Mk-7 bomb prototype. With a weight of only 1800 lb and a diameter of 30 inches this bomb represented a drastic size reduction over its Fat Man-size (10,000 lb, 60 inch diameter) predecessors. The design used an 800 lb. assembly of high explosive (primarily Octol 75/25), with a composite uranium-plutonium core. The predicted yield was 22-35 kt.
http://nuclearweaponarchive.org/Usa/Tests/Busterj.html

Dog
Operation Buster
The test device, designated "NF", was a Mk 4 bomb assembly of a composite uranium-plutonium core. The expected yield was 18-25 kt.
Desert Rock I - the first U.S. nuclear field exercise on land was conducted in association with the Dog shot. In the weeks before the shot the assembled troops (from the 188th Airborne, 127th Engineer Battalion, and the 546th Field Artillery Battalion) dug field emplacements to simulate a defensive deployment southwest of the shot location. The troops observed the shot from a point six miles from ground zero, were transported to the defensive emplacements to view the weapon effects, and then conducted maneuvers in the area. Since this shot was an airburst there was no local fallout, although some neutron-induced radioactivity existed.

Charlie
Operation Buster
The test device, designated "PC", was a Mk 4 bomb assembly of a composite uranium-plutonium core. The expected yield was 12-15 kt.

Baker
The test device, designated "LT", was a Mk 4 bomb assembly consisting of a plutonium core without a uranium tamper. The expected yield was 3-8 kt.

Able
Less .1 kt
Tower (30m)
This was a test of the Petite Plutonium fission bomb, designed by Ted Taylor. It consisted of a standard 60 inch, 10,000 lb. implosion system with the plutonium core reduced to what was estimated to be close to the minimum amount of fissile material for an appreciable yield. This was the lowest yield design yet tested, with a predicted yield of only 200 tons. It was a fizzle - the first actual failure of any U.S. nuclear device (the 18th exploded by the U.S.), and the first known failure of any nuclear device. Rather than being a sign of ineptness, this failure was indicative of the increasingly aggressive (and thus risky) U.S. experimental approach to weapon development. It established a close lower bound on the minimum amount of plutonium that could be used in a weapon to produce a significant yield, an important benchmark in weapon design.
This was inadvertently a "zero yield" test. The device achieved supercriticality and produced detectable nuclear output, but the energy produced was negligible compared to the high explosive used. The tower was damaged but largely intact from the test.
The first attempt to fire this device (on 19 October) was a true failure - nothing happened. The problem was traced to the control circuitry.

Buried Objects Detection Facility
The Buried Objects Detection Facility is a unique facility operated by LLNL to evaluate new mine detection hardware.
The Buried Objects Detection Facility was established to help in the detection and neutralization of anti-tank mines, which, alone with anti-personnel mines, are high on every humanitarian organization's priority list. The goal of the facility is to provide experiments with an area where they can evaluate possible solutions to the detection of anti-tank mines.
The facility is avilable to military and civilian research efforts for detection and the characterization of various buried objects, including sphere, drums, and pipes, but specifically anti-tank mines. All of the mines and other structures are precisely mapped and characterized. For personnel safety, the mines are all defues; however, for detection purposes, all contain their original main explosive.
The facility covers 100 acres, of which 30 acres are in a secure enclosed area. The secure are contains 296 mines, 276 of which are available to experimenters to use for uniform calibration of their detection instruments, while the characteristics of the other 20 are kept from the experimenters. These 20 then become the actual search objects.
The are is typical of the high desert geology and soil conditions prominent at the NTS, and the earth has been undisturbed since the mines were introduced to the are in 1993 and 1994.

Calibration Gun Turret
This gun turret was removed from a pre-1940s scrapped US Navy heavy cruiser. The old steel used to forge the turret was selected because it had not been contaminated by radioactive fallout, thereby ensuring accurate calibrations. The turret, with its 45-inch diameter barrerl, was connected with buried coaxial cables to the nearby instrument block house (presently being used by Sandia National Laboratories) which relayed information from the Whitney, Shasta, Diablo, and Smoky atmospheric tests that were detonated in Yucca Flat during the 1960s.

U1a Complex
Previously known as the Lyner Complex.
The underground U1a Complex is the location for subcritical experiments. Subcritical experiments are physics experiments that obtain technical information to help the National Laboratories maintain the safety and reliability of the U.S. nuclear weapons stockpile.
The U1a Complex is an underground laboratory consisting of horizontal tunnels, each about one half mile in length, where experiments supporting the nation's nuclear stockpile are conducted. The U1a Complex is mined at the base of a vertical shaft approximately 960-feet below ground surface. The vertical shaft is equipped with a mechanical hoist for personnel and equipment access while another vertical shaft, about 1,000 feet away, provides cross ventilation, instrumentation and utility access, and emergency exits.
