W81
The W81 was a planned American warhead to be mounted on the RIM-67 Standard, SM-2 surface-to-air missile used by the United States Navy. The W81 was believed to be derived from the B61 nuclear bomb which forms the backbone of the current US nuclear gravity bomb arsenal and from which the W80 (nuclear warhead), W80 cruise missile warhead is derived. The weapon was being designed at Los Alamos National Laboratory (at the time called Los Alamos Scientific Laboratory)., Design The W81 went through several design iterations, starting with an Neutron bomb, enhanced radiation model, then a pure fission model and cancelled in 1986. Characteristics are not known in detail, but the B61 nuclear bomb, B61 it is derived from has a physics package (bomb core) of about diameter with length of , weighing around (see the W80 (nuclear warhead), W80, another B61 nuclear bomb, B61 derived design). Available LASL images show a much shorter weapon, perhaps , probably the final fission-only W81 conce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B61 Family
The B61 Family is a series of nuclear weapons based on the B61 nuclear bomb. B61 nuclear bomb Initial development The B61 bomb was developed by Los Alamos Scientific Laboratory (LASL; now Los Alamos National Laboratory) starting in 1960. The intent was to develop an aircraft bomb which was high yield (over 100 kilotons) and yet was small enough and had low enough drag to carry under the wing of a fighter or fighter-bomber type aircraft. One major feature was Full Fuzing Option, allowing various air and ground burst usage options; free fall air burst, parachute retarded air burst, free fall ground burst, parachute retarded ground burst, and laydown delivery. The B61 project started in 1960 with a study contract analyzing the potential of such a weapon. The official development program was funded in 1961, and the weapon was designated TX-61 (Test/Experimental) in 1963. The first TX-61 free fall ballistic test was held at Tonopah Test Range on August 20, 1963. The first War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Nuclear Weapons
This is a list of nuclear weapons listed according to country of origin, and then by type within the states. United States US nuclear weapons of all types – bombs, warheads, shells, and others – are numbered in the same sequence starting with the Mark 1 and () ending with the W-91 (which was canceled prior to introduction into service). All designs which were formally intended to be weapons at some point received a number designation. Pure test units which were experiments (and not intended to be weapons) are not numbered in this sequence. Early weapons were very large and could only be used as free fall bombs. These were known by "Mark" designators, like the Mark 4 which was a development of the Fat Man weapon. As weapons became more sophisticated they also became much smaller and lighter, allowing them to be used in many roles. At this time the weapons began to receive designations based on their role; bombs were given the prefix "B", while the same warhead used in other r ...

RIM-67 Standard
The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) and anti-ship missile originally developed for the United States Navy (USN). The RIM-67 was developed as a replacement for the RIM-8 Talos, a 1950s system deployed on a variety of USN ships, and eventually replaced the RIM-2 Terrier as well, since it was of a similar size and fitted existing Terrier launchers and magazines. The RIM-66 Standard MR was essentially the same missile without the booster stage, designed to replace the RIM-24 Tartar. The RIM-66/67 series thus became the US Navy's universal SAM system, hence the "Standard Missile" moniker. RIM-67A SM-1 Extended Range The RIM-67A (SM-1ER Block I) was the Navy's replacement for RIM-8 Talos missile. Improved technology allowed the RIM-67 to be reduced to the size of the earlier RIM-2 Terrier missile. Existing ships with the Mk86 guided missile fire control system, or "Terrier" were adapted to employ the new missile in place of the olde ...

United States Navy
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2015. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the United States Navy is the third largest of the United States military service branches in terms of personnel. It has 290 deployable combat vessels and more than 2,623 operational aircraft . The United States Navy traces its origins to the Continental Navy, which was established during the American Revo ...

B61 Nuclear Bomb
The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War. It is a low to intermediate-yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design. The B61 is of the variable yield ("dial-a-yield" in informal military jargon) design with a yield of 0.3 to 340 kilotons in its various mods. It is a Full Fuzing Option (FUFO) weapon, meaning it is equipped with the full range of fuzing and delivery options, including air and ground burst fuzing, and free-fall, retarded free-fall and laydown delivery. It has a streamlined casing capable of withstanding supersonic flight and is long, with a diameter of about . Basic weight is about , although the weights of individual weapons may vary depending on version and fuze/retardation configuration. As of 2020, it is undergoing a 12th modification. According to the Federation of American Scientists in 2012, the roughly 400 B61-12s w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
W80 (nuclear Warhead)
The W80 is a low to intermediate yield two-stage thermonuclear warhead deployed by the U.S. Enduring Stockpile, enduring stockpile with a variable yield ("dial-a-yield") of . It was designed for deployment on cruise missiles and is the warhead used in all nuclear-armed AGM-86, ALCM and AGM-129 ACM, ACM missiles deployed by the US Air Force, and in the US Navy's BGM-109 Tomahawk. It is essentially a modification of the widely deployed B61 nuclear bomb, B61 weapon, which forms the basis of most of the current US stockpile (military), stockpile of nuclear gravity bombs. The very similar W84 warhead was deployed on the retired BGM-109G Ground Launched Cruise Missile. Dimensions The W80 is physically quite small: the physics package itself is about the size of a conventional Mark 81 bomb, Mk.81 bomb, in diameter and long, and only slightly heavier at about . History Early development The Los Alamos National Laboratory began development on the W80 in June 1976, with the brief of ...

Los Alamos National Laboratory
Los Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing nuclear weapons under the Manhattan Project during World War II.The site was variously called Los Alamos Laboratory and Los Alamos Scientific Laboratory. Chosen for its remote yet relatively accessible location, it served as the main hub for conducting and coordinating nuclear research, bringing together some of the world's most famous scientists, among them numerous Nobel Prize winners. The town of Los Alamos, directly north of the lab, grew extensively through this period. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutron Bomb
A neutron bomb, officially defined as a type of enhanced radiation weapon (ERW), is a low-yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while minimizing the physical power of the blast itself. The neutron release generated by a nuclear fusion reaction is intentionally allowed to escape the weapon, rather than being absorbed by its other components. The neutron burst, which is used as the primary destructive action of the warhead, is able to penetrate enemy armor more effectively than a conventional warhead, thus making it more lethal as a tactical weapon. The concept was originally developed by the United States in the late 1950s and early 1960s. It was seen as a "cleaner" bomb for use against massed Soviet armored divisions. As these would be used over allied nations, notably West Germany, the reduced blast damage was seen as an important advantage. ERWs were first operationally deployed for anti-ballistic missil ...
