I think what he means that Stealth of an aircraft depends on many factors ( climate ,maintenance ,tolerance ) and an aircraft would maintain its LO or it would get degraded depending on how well all of these factors can come into play in actual combat.

. No chance in the near future. Unless we can see them reducing the number of roads built around AP or the like it will be diff to tell.
'Phase of the moon' is also a colloquial expression meaning 'depending on arbitrary unknown factors'. We use it all the time in the IT world (e.g. Windows bluescreens depending on phase of moon), though this slang term is pretty widespread in other fields as well.Gaur wrote:^^

True. This plane was designed to make strikes deep in the former Soviet Union. After the Soviet Union collapsed in the early 90s, the raison d'etre (or 'raisin-dieter' if you prefer) of the aircraft was gone and there was no need to make additional aircraft. At the same time, the US economy was having troubles too and President Bush Sr. was under pressure to make budgetary cuts.Production was limited because there are not enough appropriate targets to strike. The technology is wonderful, but "it don't make sense!"
The actual facts are that the original congressional order asked for 132 aircraft to be produced and Northrop priced them at about $400 mil per bomber. Then a little while later, Congress reduced the order to 75 aircraft and Northrop had to up the price to about $800 mil per. Then they reduced it to 21 bombers and the price jumped to about $2.2 billion per bomber. Why?? Because Northrop had spent a huge amount up front on R&D, as well as setting up a specialized plant and tools and hiring shop personnel who were cleared at the highest levels, all so that they could start manufacturing the B2. They had to recover their costs somehow, which is why they had to increase the price per aircraft when the # of planes ordered went down.The aircraft was too expensive to produce. I doubt this. It is the first two dozen that are expensive. Thereafter costs should decline significantly.
It is true that stealth is difficult to maintain and the aircraft need a lot of maintenance per flight. E.g. they apparently need to apply some special sealants after the pilots have got into the aircraft, to coat the bomb bays, doors etc to reduce the radar signature. One hour of B2 flight reportedly needs 100+ hours of ground maintenance. In addition, the aircraft need a large air-conditioned hangar to maintain the stealth properties of their coatings. Speaking about Guam vs. North India and dusty conditions, it might be worth to point out that one of the airbases that the B2 Spirit live in is the Nellis AFB in Nevada, which is an extremely dusty and hot environment.Stealth is difficult to maintain. The bases are extremely special and the aircraft probably have to undergo not only very critical pre-flight preparations and checks but elaborate post launch procedures to ensure stealth is intact during the climb through 'contaminated' lower levels. Guam in mid-pacific is unlikely to be dusty. How about North Indian summer?

Zhang's article in the "Science and Global Security" says China stopped production of enriched uranium in 1987 and plutonium in 1990, diverting resources towards nuclear fuel used for civilian purposes. A careful satellite study of Chinese facilities and calculations of use of fissile material had led to these estimates.
China's nuclear programme was aided by the erstwhile Soviet Union before Russia broke cooperation after Mao Zedong's assertive policies. The facilities were then located in south-west China — far from the coast and border with the Soviet Union — and became operational in the 1970s.
The new plutonium estimate, says Zhang, is consistent with a US department of energy assessment from 1999 that China had a stockpile of 1.7–2.8 tonnes of plutonium for weapons.
The stocks might be more modest than estimated, but this does not necessarily spell comfort for India as most of China's missiles are in the mid-range that covers the Indian landmass. Some Western reports put China's stockpile at 240 warheads, with 175 in active mode and 65 in reserve. But many missiles are not clearly distinguished as nuclear capable, fuelling confusion and panicky reactions.

regardless of what the chinese certainly have a way to do PR now!!releasing all the pics at the same time saying the project is ultrasecret so that there is no information on public domains
It's OK ranjithnath - its not about you - but it is entirely possible that I am losing it. Or alternatively I am right. The more I look around at the media and "analyses" the more I begin to feel that the ratio of clued up to clueless is miniscule. Sorry to go OT - but you have to bore yourself watching 2-3 minutes of CNN analysis of Bin Laden family video to realise how stupid analyses can get.By Chinese propaganda standards this photo is a bad one. China is falling behind. I yearn for the days when al-photoshoppe wouid create a row of tanks 40 abreast and 1000 long to make viewer shiver. The new open China is losing it.

Any direct confrontation with china at this point of time is not in India's interest. India first needs to grow economically and technically and decisively prove that Democracy is not barrier to growth but is a facilitator of growth. And single party rule and dictatorship are irrelevent and raise chinese people against their regime for democracy for human rights there by "soft landing" like Soviet union not like hard landing NaziGermanyKailash wrote:Army chief briefs PM on China’s role in POK
Does anyone remember the last time our PM or his government openly confronting the Chinese? They are constantly harrassing us with stapled visas, capture/killing of fishermen by the SL navy, lobbying against us on every major issue, building N-reactors for pak, keeping us out of the security council, ring of pearls, and now stationing troops in Pakistan.
Human rights atrocities, autonomy of tibet, LAC, dam across bhramputra, taxes or ban on imports, take ULFA/Maoist connections to Chinese arms, their listening posts, conterfeit auto parts and medicines, waking up ambassidors at the middle of the night.... we can blow up any of these issues. If only we had the guts to put our foot down and say - "enough... now take a step back. If you dont want friendship, we have enough cards to play against you". The government's memory seems to be as shortlived as DDM's and our determination to pursue these issues is seriously lacking.
So they are ahead in terms of infrastructure and arms production capabilities. So what? Why is that being turned to some sense of "wanting to appease" or "ensure never to offend" the Chinese? Why is the Indian reaction so mute in this matter?

..it distributes the CG I guess, or there can be better explaination.
That helo has a very very broad base indeed. I suspect they must have been made for "hovering tests" close to the ground where any tendency to suddenly topple over due to poor control would be compensated by a part of the broad base touching the ground before that happened.kmkraoind wrote:China Tests Helicopter Drone

Sometime back I predicted that china is planning its own great game there, for that it needs to weaken India.The Army Commander said China had made inroads around India thus posing substantial challenges not only along the China-Indian border but also along the Line of Control (LoC).
He said ‘a great game is being played by Chinese expansionism and by mushrooming terror networks,’ adding that it was imperative to take control of the situation in Jammu and Kashmir and find a viable solution to internal problems of the State without interference from Pakistan.
