アメリカ. 費やすだろう $1.3 billion to develop advanced satellites that will be able to better track hypersonic missile threats, インクルード 五角形 said Monday, announcing two new contracts that will put the detection and tracking systems in orbit by 2025.

Derek Tournear, director of the Space Development Agency, said the contracts will provide 28 衛星, アメリカとして. moves to greatly expand and enhance its ability to counter increasing threats from ロシア そして 中国.

Both countries have been making strides in their development of hypersonic missiles, which are more difficult to track and shoot down because they maneuver more in flight than conventional weapons that travel in predictable paths. Last year China tested what U.S. officials said was a hypersonic missile, and Russia has used the weapons in strikes during the war in Ukraine.

“Russia and China have been developing and testing hypersonic glide vehicles — these advanced missiles that are extremely maneuverable,” Tournear told Pentagon reporters Monday. “These satellites are specifically designed to go after that next generation version of threats out there so that we can detect and track these hypersonic maneuvering vehicles and predict their impact point.”

Additional funding for the program was provided by Congress specifically in response to concerns in the Indo-Pacific region, in response to China’s rapidly progressing military development.

Hypersonic weapons are defined as anything traveling beyond Mach 5, or five times faster than the speed of sound. それは約です 3,800 mph (6,100 kph). Intercontinental ballistic missiles far exceed that threshold but travel in a predictable path, making it possible to intercept them.

歴史的に, Tournear said, アメリカ. has not flown satellites that were designed to detect and go after such maneuverable hypersonic weapons. 現在, 彼は言った, “we have limited capability to do that tracking aspect.” 彼が追加した, しかしながら, that “clearly we don’t have zero capability to do tracking.”

The new satellites, 彼は言った, will enable the U.S. to detect the launch, follow the hypersonic missile as it changes course, calculate where it is heading and provide that data to forces who can launch interceptors.

The contracts were awarded to teams led by L3Harris Technologies, 株式会社. of Melbourne, Fla., and Northrop Grumman Strategic Space Systems of Redondo Beach, カリフォルニア. L3Harris will produce 14 satellites at a cost of about $700 百万, and Northrop will produce 14 at a cost of about $617 百万. The total cost of the program, including the launches and ground control and support, will be about $2.5 十億.

Tournear said the program represents a shift for the U.S. toward a larger, overlapping system of satellites. Rather than relying on larger, more expensive satellites that stay in orbit for 15 or more years, アメリカ. will have a greater number of cheaper satellites that would be replaced about every five years.

One set, 彼は言った, would be at a lower orbit of about 1,000 キロメートル, and a second set would be at a medium orbit of about 10,000-20,000 キロメートル, providing a more resilient presence. He said the first 28 satellites would likely be followed by a second group of about 54.

今年の初め, アメリカ合衆国, United Kingdom and Australia announced that they will work together to develop hypersonic missiles. The April announcement came amid growing concerns about China’s escalating military assertiveness in the Pacific. 昨年10月, 我ら. 陸軍Gen. マーク・ミリー, 統合参謀本部議長, confirmed that China had conducted a test of a hypersonic weapon, calling it a “very significant event” that wasvery concerning.”
