Chinese hackers stole 50 terabytes of United States classified military documents and information including of Joint Strike Fighter known as Lockheed Martin F-35 Lightning II, reports German magazine Der Spiegel. In the document of National Security Agency – said to be leaked by Edward Snowden – shows that Chinese hackers stole information on radar systems, detailed engine schematics which involves methods for cooling exhaust gases and aft deck heating contour maps, plus many terabytes of F-35 data.
It is believed that China’s next-generation fighters Chengdu J-20 and Shenyang J-31 programs greatly benefited from Joint Strike Fighter program. The stealing of information and documents that apparently transpired in 2007 saved China from couple of decades of research and development, military experts believe.
The said size of stolen data, 50 terabytes, is equivalent to five libraries of US Congress. Documents on B-2, F-22, space-based laser, designs of US Navy’s nuclear submarine and anti-air missile were also stolen.
