What can a 150 kiloton bomb do that cannot be achieved by five 20 kioton bombs?
Five 20 KT can do nothing unless it first reach the target.
The lighter 150 KT TN OTOH can reach a target far in excess of teh five 20 kt. Conversly one needs 5 to 10 time more missiles, aircrafts, ships, subs to deliver the payload. Or indeed a PSLV to deliver 20 kt flower petals at range.
Let me rephrase the question differently.
Does anyone have any idea whether one could use available and limited supplies of fissile material more efficiently (in terms of number of weapons, cost and maintenance and use) if one had an arsenal of bigger bombs rather than smaller ones.
Good question. In terms of big (FBF) and small (FBF):
Code: Select all
Bigger ones, Smaller ones
Number of weapons, Fewer need many times larger qty
Cost decidedly cheaper Mighty more expensive
Maintenance and security decidedly cheaper Much more expensive
Fissile material use slight advantage slight disadvantage
What is the lower yield limit of an ideal thermonuclear weapon that meets the above requirements?
Let it be more clear. Nuclear Weapon are tailor made system of warhead and delivery vehicle combination. Thus Sagarika, A1, A2,A3,A5 all will have a different ideal TN yield depending on CEP (which is amongst others a function fo range) of non-MIRV/MIRV configuration.
Thus IMHO the ideal yield for these different weapons will be between 100 and 400 kT.
