An US intelligence official confirmed to Financial Times that Pakistan shared with China samples of material and photographs of the US stealth helicopter that crashed during the raid on Osama bin Laden. The helicopter seems to be engineered to avoid radar detection. It was destroyed after a hard landing during the raid on Osama bin Laden and returned after a few days to the United States.

According to Aviation International News, the helicopter was a modified version of the MH-60 model, probably built in 2009. The skin seems to have been covered with a silver compound to minimize infrared detection.
The pair of “low-observable” Sikorsky Black Hawks used in the raid by U.S. forces against terrorist Osama bin Laden’s Pakistani compound May 2 were kitted with a variety of stealth and radar-defeating features that had been in development since the 1970s, and maybe longer. The helicopters came to light after one had to be left behind and intentionally detonated after apparently clipping a compound wall and making a hard landing. While the explosion destroyed most of the helicopter, parts of the empennage, stabilizer, tail rotor and tail-rotor hub survived and were extensively photographed by the international news media, giving rise to initial speculation that the U.S. used a new stealth helicopter. However, in the weeks that followed, experts, including those who spoke with AIN, dismissed the idea that a totally new helicopter had been used. Serial numbers on parts at the scene indicate that the destroyed helicopter was an MH-60 built in 2009.
The Obama administration discussed this incident and is actively looking into the matter. Pakistan has repeatedly indicated that it considers China its main strategic ally, despite the fact that the US gives Pakistan almost 3bn in military aid annually. Pakistani officials also arrested the local officers and civilians that collaborated with the US in eliminating Osama bin laden.
The US has recently reduced by 1/3 the aid and is considering new measures against Pakistan.
