Countries with nuclear arsenal


Countries with nuclear arsenal 

These can be classified into five types:

  1. Countries which have entered into NPT
  2. Countries which haven't entered into the NPT
  3. Countries which are believed to have nuclear war-heads
  4. NATO (war-head sharing countries)
  5. states formerly possessing nuclear war-heads

Countries which have entered into NPT:

Under "non-proliferation treaty" five countries are considered to be "nuclear weapon states".
They are 
1. USA (7315)
2. Russia (8000)
3. France (300)
4. United kingdom (225)
5. China (250)

USA has build nearly 70,000 nuclear war heads during 1949 cold war, and Russia has build nearly 55,000. These weapons are said to be decommissioned or partially stored, but are "not destroyed" 

Countries which haven't entered into the NPT:

Since the NPT entered into force in 1970, three states that were not parties to the Treaty have conducted nuclear tests, namely India, Pakistan, and North Korea. North Korea had been a party to the NPT but withdrew in 2003.

Countries which are believed to have nuclear war-heads:

Israel is widely believed to have been the sixth country in the world to develop nuclear weapons, with “rudimentary, but deliverable,” nuclear weapons available as early as 1967. Israel is not a party to the NPT. Israel engages in strategic ambiguity, saying it would not be the first country to "introduce" nuclear weapons into the region, but refusing to otherwise confirm or deny a nuclear weapons program or arsenal. This policy of "nuclear opacity" has been interpreted as an attempt to get the benefits of deterrence with a minimum political cost. In 1968, the Israeli Ambassador to the United States, Yitzhak Rabin, affirmed to the United States State Department that Israel would "not be the first to introduce nuclear weapons into the Middle East." Upon further questioning about what "introduce" meant in this context, however, he said that "he would not consider a weapon that had not been tested a weapon," and affirmed that he did not believe that "an unadvertised, untested nuclear device" was really "a nuclear weapon." He also agreed, however, that an "advertised but untested" device would be considered "introduction." This has been interpreted to mean that official Israeli policy was that the country could possess a nuclear weapon without technically "introducing" it, so long as it did not test it, and as long as it was "unadvertised".
 According to the Natural Resources Defense Council and the Federation of American Scientists, Israel likely possesses around 75–200 nuclear weapons.

NATO (war-head sharing countries):

Under NATO nuclear weapons sharing, the United States has provided nuclear weapons for Belgium,Germany, Italy, the Netherlands, and Turkey to deploy and store. This involves pilots and other staff of the "non-nuclear" NATO states practicing, handling, and delivering the U.S. nuclear bombs, and adapting non-U.S. warplanes to deliver U.S. nuclear bombs. However, since all U.S. nuclear weapons are protected with Permissive Action Links, the host states cannot arm the bombs without authorization codes from the United States Air Force. U.S. nuclear weapons were also deployed in Canada until 1984, and in Greece until 2001 for nuclear sharing purposes.
Members of the Non-Aligned Movement have called on all countries to "refrain from nuclear sharing for military purposes under any kind of security arrangements." The Institute of Strategic Studies Islamabad (ISSI) has criticized the arrangement for allegedly violating Articles I and II of the NPT, arguing that "these Articles do not permit the NWS to delegate the control of their nuclear weapons directly or indirectly to others." NATO has argued that the weapons' sharing is compliant with the NPT because "the U.S. nuclear weapons based in Europe are in the sole possession and under constant and complete custody and control of the United States.

states formerly possessing nuclear war-heads:


South Africa, Belarus, Ukraine, Kazakhstan are known to be states which possess nuclear warheads but disposed them later.
Ukraine used to have nearly 5,000 nuclear war heads before the separation from the soviet union. But it has voluntarily disposed them. 




  NPT-designated nuclear weapon states (China, France, Russia, United Kingdom,United States)
  Other states with nuclear weapons (India, Pakistan, North Korea)
  Other states believed to have nuclear weapons (Israel)
  NATO nuclear weapons sharing states (Belgium, Germany, Netherlands, Italy, Turkey)
  States formerly possessing nuclear weapons (Belarus, Kazakhstan, Ukraine, South Africa)

Snap-lock , Snaphance and flintlock

Snap-lock, Snaphance and Flintlock These three fire arms work under same mechanism. The difference is the protective measures development  in each of the fire arms. The order of the fire arms is snaplock snaphance flintlock percussion cap Mechanism: The operation works on the old concept of fire sparks ( when two rocks are rubbed against each other the friction between them causes a spark and eventually fire when the sparks are in contact with a dry grass or to be more precise, a conductor which ignites under a slight high temperature). The firearm consists of a flint material and a steel plate placed against each other. When the flint is held with a spring, potential energy is stored in the spring. When the trigger is released the potential energy is transferred to the clamped flint and the clamp moves forward and strikes the hardened steel producing sparks. These sparks flash pan travels through the touch hole and ignites the gun powder and boom. ...

History of firearms

Pistol/Guns/Fire arms 1       history All about the pistols, hand guns had begun in early 12 th century in China. There took the birth of the firearm named hand cannon in 1200 and from there the knowledge has spread throughout the world. It is believed that the gun powder technology has spread to the west through Silk Road. Europe and Arabs have been using them in 14 th century, and japan has started mass producing them in 1543, but they know about the gun powder in the beforehand. After the gun powder was invented by China the advanced firearm was introduced by Portuguese in 15 th century. These were used until 1720 when they were replaced by flintlocks. The evolution of firearms is shown below: Hand cannons (14 th century) Hand locks- hand gonne (15 th century) Match lock Wheel lock (15 th century) Snap lock Snaphance (1550) Dog lock (17 th century) Flintlock (17 th century ) Percussion cap...

Match lock

Match lock: Now that we have reduced the cannon balls or projectiles and made them into a compact size, the barrels used for the projectiles are also small. The force that must be applied for the projectile must be enough that it penetrates the enemy. The guns which are used in the early 14th century have used match lock technology. match lock nothing a defined technology. It works on the same concept of the cannons. But he thing is it is lit by a fire using a combustible substance. The gun has a barrel in which the projectile is placed and pushed tightly towards the gun powder. this gun powder is lit by a dry thread/wick which has its extension into the chamber in which the gun powder is filled. As soon as the power is ignited, it creates a blast and throws the projectile toward the target. These match locks were remained in the use until 17th century. These matchlocks had a great disadvantage- They take time to lit the wick and even when the wick is lit it takes ...
