For now a FBF 150 kt bum is ok. Why rock the boat for another 50 kt (200 kt TN) ? Perhaps not even that. ~100 kt seems to be the choice for the UK, ... ... So basically we are talking about the number of warheads an Indian SSBN can deliver and the total number of warheads in the Indian arsenal (FBF...

I am sure they had high confidence on S1 too till the moment S1 was tested. But I believe in BARCs mastery of boosted weapon. The question is credible yield that puts fear in the mind of adversary. That is a very loaded statement. Is it megatons or few hundered kilotons? Is it 300 kt and above or @...

We know how to make a bomb work, but Can we say for sure every bomb we make works? (with no more than 6 tests on record) If the answer is yes then no testing only fielding! The answer is yes. The fatboy on Nagasaki, eventhough big was "tested" only once. They worked on the bomb design onl...

What if the enemy launched ASAT satellites purely as a defensive measure and does not intend to launch nukes - You mean an ASAT weapon to take *your* sat out. Not its sat. Assuming your sat goes out due to ASAT, isn't that itself a launch of nuclear war, particularly your "infrastructure"...

disha

so basically be on a hair trigger at the prospect of an ASAT launch. Nice , i like your way of thinking , but it breeds instability. and if the warheads are indeed inaccurate they need larger yields . your scenario once again leaves out the prospect of the enemy's counter-strike as well. Can you qu...

Proposing MAD? If they were so careless about their own citizens, why do not we have them in a nuke war with say US? China is deterred because the US can destroy them many times over. The US is deterred because it is unwilling to lose a single city to the Chinese. Hmm, So by the same analogy, we ca...

For a goal of 8 citiies - 500 warheads - even of 15 kilotons, with a 90% failure rate will ensure that 6 Hiroshima size bombs will hit each targeted city. Where is the need to test any further if this goal is acheivable? This assumes that an enemy will be deterred by the prospect of losing 8 cities...

2. It is known in our neighbourhood, that we have the capability of MIRV *and* accuracy. [Look at the PSLV launch]. ... as I have written before this CEP stuff will be rendered useless given the fact that a first strike on us will certainly try to take out our satellite guidance assets. Then test a...

I honestly dont know about the first part. Its the latter I do know- its difficult to scale. I do believe that we have the know how of going upto 300 Kt. The question I have is why do we need to go beyond 300 kt? Why 1 MT or 2 MT? Here are the reasons: 1. The ratio of accuracy to radiation damage t...

Is boosted fission easily scalable? I recall news reports right after the 1998 tests which quoted some scientist saying that they could have easily increased the yield had they put more Tritium. Fusion boosted fission [FBF] is *not* scalable. The only scalable thing is the Teller-Ullam design which...

testimony of Richard Garwin Very very selective quotes - psyops or what? Read it as follows: That amount of fissile material would suffice for 10 thermonuclear weapons, each of which could be in the megaton class and weigh less than 1000 lbs. However, such H-bomb type weapons would require testing ...

disha

Thats the whole question IMVHO; if S1 worked we say boosted fission device works; but if S1 does not work do we know why? What if primary did not give the expected yield? Sanku, fission devices and boosted fission devices are actually very easy. The complexity is in the triggers! I will go into the...

The difference between pontoons and land based silos is that for anyone to get physically close to a land based silo they would have to be inside Indian territory. Pontoons out in open waters is like planting a Rs 100 note (attached to a string in your hand) in the middle of the road and waiting fo...

The idea of using sunk pontoons as silos for Sagarika has some inherent disadvantages 1) These pontoons need to be stationed at 50 meters depth so that would limit how far in to the sea we can go as the oceans get progressively deeper farther from the shore. 2) Once sunk their locations need to be ...

Unmanned and fixed underwater barges holding nuclear tipped missiles are open to attacks, and hence are a big security problem. Land-based silos are protected by ABMs atleast. :?: :?: :?: :?: What is the coast guard for? 50 km off the coast, an ABM battery cannot protect an underwater barge? On the...

AOA! So the idea is to drop real K-15 pantoons sprinkled within the dummy pantoon distribution? 1). They will be detected by satellite. 2). MPA's will decipher real ones from dummies. 3). Uncle's rig will come and steal (tow) away a couple of pantoons from 'international waters' for analysis. Yindo...

Folks dont you think such stationary launching pilons or silos be detected by satellites? IR detectors the difference between waters around and the silo. What about corrosion etc? Sink several dummy pontoons all over the place. Some of them can have real fat ladies which sing once in a while. Lizar...

Filing a patent would be a stupid thing to do. It just makes it so easy for some one else to build an exactly similar system for themselves. As long as they don't commercially sell it, they wouldn't even be violating the patent. If you really come up with something new, especially in the defence fi...

To err is human. Editors want to cram in all the news that flows via wire with gramatical and space edits. It is because of the work pressure.
