China has reportedly revealed its top-secret supersonic spy drone for the very first time at a rehearsal for an upcoming military parade.

It is said that Wuzhen-8 is capable of travelling faster than Mach 3.3 and can reach strategic locations as far as Guam, part of the US territory in the Western Pacific.

The unmanned aerial vehicle was spotted over the weekend in Beijing during a drill for China's National Day military parade, according to Chinese media.

The photo (above) has sparked speculation among Chinese military fans. South China Morning Post reported that the picture captured Beijing's mysterious Wuzhen-8 supersonic spy drone

Other military aircraft that were captured include 'Sharp Sword' stealth drone, the report said

The parade, set to be the largest demonstration of China's military might ever, will take place on October 1 in Beijing to mark the 70th anniversary of the founding of the Communist Nation.

It's set to showcase some of the country's most advanced weaponry.

Wuzhen-8 has been developed by Beijing to fight US troops should there be a conflict in the South China Sea or Western Pacific, according to South China Morning Post.

A Shanghai-based expert told the newspaper that Beijing's People's Liberation Army had been using the reconnaissance drone for some time.

However, public information about the aircraft is little, and China has never released any pictures of the it.

It is believed that the drone took its first test flight in 2015. China Aviation News said in a report that it flew 'for a few hours', suggesting it could be a long-range spy drone.

China organised the second rehearsal for its National Day military parade over the past weekend in its capital city.

Streets of a large part of central Beijing were closed for the practice session, which involved more than 280,000 people, according to China's state broadcaster CCTV.

Beijing's authorities have also banned residents from flying kites, pigeons and drones out of security reasons until after the parade.

Pictures of the rehearsal taken by Beijing residents have sparked discussions among military enthusiasts on social media.

Other weapons that were captured include 'Sharp Sword' stealth attack drone and hypersonic DF-17 missile, said South China Morning Post.

'Sharp Sword', a 33-foot-long craft, is said to be able to carry up to two tonnes of bombs.

DF-17, or Dongfeng-17, is said to be capable of achieving speeds of up to 7,680 miles per hour (12,360 kph) - or 10 times the speed of sound - while carrying a nuclear warhead.

Hong Kong-based Ta Kung Pao reported that DF-41 missile also appeared at the rehearsal.

Previous reports claimed DF-41 has the longest range of any ballistic rockets in the world, and could reach London or the United States with nuclear warheads.
