That is a strange looking tail rotor for a typical UH-60 Black Hawk helicopter. Therefore the idea of modified one to be more stealth for this particular raid on OBL is possible.
 
The Pakistanis probably sold the reamining parts of the aircraft to the Chinese. Great.

Could you please tell us all how much of USA debt is held by Chinese before you blame Pakistan for selling any thing should not you ask how much of USA is sold to the the Chinese by Americans themselves.
 
As mentioned in the above article given by Ang stealth helcopters are nothing new.

The BOEING-SIKORSKY RAH-66 COMANCHE STEALTH HELICOPTER was going to be the first stealth copter in the world but it was abadond due to cost and favors of UAVs

heres the article on RAH-66 Comanche

It also impose a very important situation....
If AMerica can penatrate into Pakistan like this , using stealth craft without being noticed, the Pakistan AIr defence, radars, SAM, Early Warning systerm is pretty useless

Can anyone explain how they were able to do this when Pakistan air defence is pretty strong ?

Hugging the Earth and the majority of Pakistan's air defence would be pointed towards India? If I remember correctly Abbottabad is hilly/mountainous correct? Doesn't seem like a good area for radar tracking.

On an unrelated note I fully expect the parts to go straight to China, and there's not much we can do about it.

Cut aid, cut spare support, aid India. That's about it.

China will take up the aid slack (but hey, that's their money going down the drain, not ours!).

After drone attacks here comes another story lol choppers came had a party and went away ,nobody was there to stop them wow .Salute to the people who taking care of Pakistan's sovereignty.Come whenever you want,do whatever you want have a great time and leave whenever you wish .What a friendship gesture ,this is what you call opening yourself to the world ,true friendship and sovereign state wow

and when you were not able to do something now after 3 days you are just saying bullshit ,we would have done this we would have done that

And i feel for poor chaps who still out of all ashes have found something for themselves to cheer about i.e oh stealth choppers woho we have find the tech now we with China will produce same tech blah blah
but my friend at what cost?
 
ref:BBC News - Bin Laden killing: What did Pakistan know?

Bin Laden killing: What did Pakistan know? Bin Laden lived in this house for months, possibly years, US officials say... Continue reading the main story

Did Pakistani intelligence really know nothing about Osama Bin Laden's whereabouts until the US raid that killed him in Abbottabad on Sunday night? How did US helicopters fly so deep into Pakistani airspace without apparently being detected? The BBC's Syed Shoaib Hasan in Islamabad talks to intelligence officials to find out more.

"The first we knew they were coming was after they had crossed the Durand line," Ayaz says, referring to the border between Pakistan and Afghanistan.

Ayaz - not his real name - works for Pakistani intelligence. He spoke to me a few days after the killing of Osama Bin Laden by US Navy Seals in north-west Pakistan.

"There were four helicopters coming in very low and the protocols set in. Jets were being scrambled, but they were called back in as the US then informed the High Command.

"They gave us a grid and told us that they were going there after "a high-value" target. There are certain protocols when that happens - we take care of the outer security, while they go in and do their work.

"We certainly didn't know who exactly was in there."


Ayaz dismisses claims that the Americans jammed Pakistan's radars.
"These type of helicopters - if they fly really low - have no real signature. But they can be sighted visually - which they were - and this led to the alert."
_52548212_011903898-1.jpg

...the authorities were apparently unaware he was right under their noses Ayaz said that Pakistani officials believed that the Americans were going to raid a hideout in the mountains near Abbottabad.

"We didn't think it was going to be right in the city."

That is something that everybody has focused on - how Osama Bin Laden could have been right under the noses of the intelligence agencies, as the authorities claim, without their knowledge.

Pakistani security officials say it was an intelligence failure - but many people find that hard to believe.

The intelligence officials I spoke to thought the compound a poor place to hide someone.

"If he was living there, it wasn't for very long," says Mahmud, another security operative.

"Anybody who has tracked Osama knows that he would never stay in one place for more than a few weeks.

"That was the cornerstone of his security - eventually people talk and information about him would get out."

Ayaz

Pakistani intelligence officer
Ayaz agrees - and then points out that an even bigger issue was the choice of hiding place.

"Just look at the house - it sticks out like a sore thumb from a mile off. You've been to Abbottabad - you know how these small towns are.

"Everybody knows everything about everybody, and secretive people are routinely investigated, especially by the police.

"If anybody wants to know about the house, they should just ask the local thana [police station]."

In addition, if Osama was with the Inter-Services Intelligence (ISI), this was the last place anybody would put him in, Ayaz argues.

"If you wanted to keep him in an urban area - we have much better protected and discreet safe houses than these.

"Theoretically speaking, if the ISI had Osama and he was being kept here, the officer responsible should be court-martialled."

'Conspicuous place'

Both men, and other intelligence and security officials, also point out there are many discrepancies in the American version of how Bin Laden was located.

"They say he was living here for such a long time - then he must have been to local hospitals," says Ayaz.

"He was not a very well man - he had kidney problems and other medical issues.

"You figure it out yourself - if he was living here for so long some news would have been filtered out."

Then there is the break in pattern. All intelligence officials say Osama Bin Laden would never wander so far from the Afghan border.

This is corroborated by senior members of a leading Taliban faction, the Haqqani network - one of whom says he met Bin Laden near the town of Chitral two months ago.

Confirming the al-Qaeda leader was dead, he said he was puzzled that he had gone as far as Abbottabad.

There is also a general consensus that Osama Bin Laden preferred living in rural Pashtun and Afghan communities - although reports of him living in cities have surfaced from time to time.

While the last official sighting of him was in the Tora Bora mountains in eastern Afghanistan in 2001, this correspondent has spoken to people who say they saw Bin Laden in Waziristan in Pakistan's tribal areas in 2004-2005.

There had been no confirmed sighting since then, until the Haqqani network member spoke after he was killed.

"For someone who was so careful about his whereabouts, why would he decide to come to such a conspicuous place?" Mahmud asks.

"There could only be one outcome of such a situation - that he would be cornered and shot."

Ayaz says he has "a strong feeling... the Americans had someone inside or in contact with the people in the compound guiding them".

"Fine, they were very good operationally - but who told them he was there and would stay?

"So if Osama was indeed killed in Abbottabad, the main share of the credit goes to this person. Without him, nothing would have been possible."

It is impossible to confirm his hunch but it is an intriguing thought.

pak got stealth heli part and us got laptop memory stick hell lot of treasure from haveli. lets see how much each worth. if isi/army really unaware of osama then congrats pak/china. you got urself a new r&d job. otherwise stealth helo parts going back to its owner!!!t
 
Pakistan did utilize the fallen dud Tomahawks that fell in Pakistan during the Clinton Era Attack on OBL Camps to design Babur Cruise Missiles.

That reverse engg. is done by china buddy.:taz:
 
So these pictures seems that rest was droped in the compound what you guys think............

we should do some labortary stuff on the material used in the airframe.....might come handy in designing intercontinental stealth cruise missile :cheers:
 
A stealthy variant of the UH-60 Black Hawk was used in the Bin Laid. With modified rotors, more rotor blades, and a stealthy fuselage, it was able to evade Pakistani radar and it is much quieter than the original.

However, the one used in the raid was a prototype and a systems failure caused it to crash. The wreckage was bombed.

Apparently the US is afraid that China will get this technology to boost its own development of stealth helicopters.

BBC News - 'Stealth helicopters' used in Bin Laden raid


The US forces who raided the safehouse of Osama Bin Laden appear to have caught him completely by surprise - and to have avoided detection by Pakistani radar. How did they do it?

One answer, experts believe, is that the special operations team used previously unseen stealth helicopters.

1. Silver finish makes it harder to detect on radar and by infrared sensors

2. Shape of tailboom has been altered and possibly enlarged to evade radar

3. Pan-like cover or hubcap over the rear rotor head conceals exposed machinery which is more easily picked up on radar

4. Extra blades on tail rotor reduce noise and lessen typical chopper sound

Rest of aircraft: There is speculation that the main rotor could also have had extra blades, retractable landing gear and a cover over the main rotor head.

The evidence for this comes from images of the wreckage of one of the helicopters, which departing Seals destroyed after it crash landed in the compound.

The tail of the top secret aircraft survived, however, providing a treasure chest of clues for aviation experts.

After some detective work, these experts have concluded it was a UH-60 Blackhawk, heavily modified to make it quieter and less visible to radar.

They are confident the raid marks the first time that a stealth helicopter has been used operationally.

It wouldn't be the first of its kind in existence, however. Sikorsky Aircraft built a number of prototype stealth helicopters, known as the RAH-66 Comanche, for the US Army. The programme was cancelled in 2004, due to escalating costs, before the helicopter become operational.

"What's new here is this was operational use," says Bill Sweetman, editor of Aviation Week. "We really haven't seen stealth helicopters used in this way before.

"The bottom line is about increasing the element of surprise. The less warning that the target has the better."

In this kind of situation an escape route for the aircraft might be needed, he adds, in which case time is of the essence.

To make a helicopter stealthy, you have to get rid of certain shapes and areas that are easily picked up on radar, says Tony Osborne, deputy editor of Rotary, a UK-based helicopter magazine.

"You have to cover key parts so that the radar waves bounce in different directions or get absorbed...

"The tail rotor gearbox is covered. I've never seen that before in a helicopter. We know things are being played with all the time, but it is impressive to see it put into action."

The tail fin is completely smooth and appears coated in a pearlescent material that looks silver in some lights, and black in others, says Mr Osborne.

"I've only ever seen that on stealth aeroplanes, and it would probably absorb radar waves. Even the rivets are covered - radars are very sensitive and small rivets could give it away.

"The tail boom remains suggest the landing gear was retractable - again, usually it could be detected by radar, so retracting it would help avoid radar detection.

"It looks like the tail rotor has five or six blades. This would mean the rotor could have a slower rotation, which would mean less noise. Noise is caused by the blade tips spinning at high speed, hitting the air."

Slipping under the radar can also be possible without stealth technology. Most of Pakistan's radars are on the ground, and therefore angled in such a way that makes low-flying aircraft difficult to detect, Mr Osborne says.

A Pakistani intelligence official who wished to remain anonymous told the BBC's Syed Shoaib Hasan that the helicopters were not picked up on radar and were only detected when seen entering the country from Afghanistan.

He said there were four helicopters, coming in very low.

There has been speculation that there was one more stealth helicopter, identical to the one that crashed, and that these were used as pathfinders, backed up by two larger Chinooks.​
 
Well I heard in document that a helicopter's tail is one of the most complex
and unique features of a helicopter

Knowing that Pakistan is blessed with the full tail of a stealth chopper i think we sued make good use of it

Like analyse the chemical structure of the metal plates on the tail and the coatings and try to see how it was done

Chine could possibly use the tail to add that to their line of helicopter productions

I don't know guys what do you think , I mean the tail looks in fantastic shape :tup::whistle:

ZZZ_050511_1.jpg


A perfectly intact stealth helicopter tail !!! WINNING

I mean the chinese helicopters could surely use this
images
 
i think main rotor might have been built on same mechanics as tail one.....tail is almost scratchless and mint :lol:....other pieces are also there...time to solve the jigsaw puzzle:agree:
