More dangerous than 'Little Boy'.. America will make the most powerful nuclear bomb

World desk:
America is preparing to make the most powerful nuclear bomb ever.  It is said to be 24 times more powerful than the atomic bomb dropped on Hiroshima, Japan.
Its name is B61-13.  This will be the 13th variant of the B61 family.  This will be a gravity bomb.  This means that this type of bomb is dropped directly on the target.  Not launched from any missile.
 The work of making B61-13 will be done under the supervision of National Nuclear Security Administration (NNSA).
 America has made this announcement at a time when China has recently talked about doubling its nuclear weapons by 2030.  And Russia has also come out of the treaty banning nuclear weapons testing.
 B61-13 will look similar to B61-7.  But the safety and control features will be better in it.  It will also have an upgraded tail kit, which will help it fall straight on the target.
 The atomic bomb that was dropped on Hiroshima during the Second World War in 1945 was named 'Little Boy'.  When this bomb fell on Hiroshima, the population there was 3.20 lakh.  By the end of 1945, 1.40 lakh people had died due to this bomb.
