US intelligence, surveillance and reconnaissance (ISR) satellites orbit at about 800 km (500 mi) high and move at 7.5 km/s (4.7 mi/s), so if conflict was to break out between the United States and China, a Chinese Intermediate-range ballistic missile would need to compensate for 1350 km (840 mi) of movement in the three minutes it takes to ...
According to officials, the United States does not have countermeasures against anti-satellite weapons. [7] On 20 February, Bloomberg News reported that the United States had informed its allies that Russia may attempt to launch a nuclear anti-satellite weapon by the end of the year.

On 11 January 2007, China conducted an anti-satellite missile test. A Chinese weather satellite—the FY-1C (COSPAR 1999-025A) polar orbit satellite of the Fengyun series, at an altitude of 865 kilometres (537 mi), with a mass of 750 kilograms (1,650 lb) [1] —was destroyed by a kinetic kill vehicle traveling with a speed of 8 km/s (18,000 mph) in the opposite direction [2] (see Head-on ...
The 2007 Chinese anti-satellite missile test was conducted by China on January 11, 2007. A Chinese weather satellite—the FY-1C polar orbit satellite of the Fengyun series, at an altitude of 865 kilometres (537 mi), with a mass of 750 kg [23] —was destroyed by a kinetic kill vehicle traveling with a speed of 8 km/s in the opposite direction ...
Project Defender attempted to destroy Soviet ICBMs at launch with satellite weapon systems, which orbited over Russia. This programme proved infeasible with the technology from that era. [1] Work then began on the Sentinel Program which used anti-ballistic missiles (ABM) to shoot down incoming ICBMs.
The Jianbing-7 class of Yaogan satellites, with military designations beginning with "JB-7", are Chinese military radar reconnaissance satellites built by SAST with an orbital period of 97 minutes and a side-looking radar system designed by the CAS's Institute of Electronics. As of July 2022, China has launched four Jianbing-7 radar satellites ...
In 2007, the Chinese military shot down an aging weather satellite, [33] followed by the US Navy shooting down a defunct spy satellite in February 2008. [34] On 18 November 2015, after two failed attempts, Russia successfully carried out a flight test of an anti-satellite missile known as Nudol .
[2] [13] Launched in 2017, 2020, and 2021, these satellites are rumored to be of the Huoyan-1 (Chinese: 火眼; pinyin: Huǒyǎn; lit. 'Fire Eyes') program — China's first early-warning satellites in geosynchronous orbit. [1] [2] [13] These purported Huoyan-1 series satellites remain fixed in orbit over the Indian Ocean, South China Sea, and ...
