China tests 5th-generation fighter jet FC-31 Gyrfalcon

China has successfully tested the latest version of its fifth-generation stealth fighter jet J-31 (now renamed the FC-31 Gyrfalcon).

The newest version of twin-engine FC-31 took to the air for the first time recently. It is considered as China’s answer to the US F-35, the world’s most technically advanced fighter.

Key Facts
  • The newest FC-31 has better stealth capabilities, improved electronic equipment and a larger payload capacity than the previous version which debuted in October 2012
  • It is manufactured by Shenyang Aircraft Corp., a subsidiary of the Aviation Industry Corp of China (AVIC).
  • FC-31 has a maximum take-off weight of 28 metric tons, flight radius of 1,250 km, and top speed of Mach 1.8 (i.e. 1.8 times the speed of sound).
  • It can easily carry 8 tons of weapons, hold six missiles in its internal weapons bay, plus another six under its wings.
  • It also has been equipped with an electro-optical targeting system and helmet-mounted display. Some analysts say the FC-31 bears a close resemblance to the US’s F-35.

China by introducing this fighter jet is trying to end the West’s monopoly on the world’s most advanced warplanes especially 5th generation fighter jet. When completed, the FC-31 will become the China’s second 5th-generation fighter after the J-20, which was put on its first public performance at the Zhuhai Air Show in November 2016.


China tests stealth-defeating quantum radar

China has claimed that it has successfully developed and tested a radar system that uses quantum entanglement to beat the stealth technology of modern military aircrafts.

This first Chinese quantum radar was developed by the Intelligent Perception Technology Laboratory. Prior to it, US was only the country stealth-defeating quantum radar.

Key Facts

  • Quantum radar is a device that uses quantum entanglement photons to provide better detection capabilities than conventional radar systems.
  • The radar system is able to detect a target at a range of 100 kilometers in a real-world environment.
  • The device employs single photon detection technology and was tested in mid-August 2016.
  • It easily tracks targets with a low radar cross section, such as modern aircraft using stealth technology or targets employing active countermeasures to jam or baffle enemy radar.

Earlier, China launched the world’s first quantum communications satellite, which uses quantum entanglement for cryptography.
