L3Harris to build prototype satellite capable of tracking hypersonic weapons
WASHINGTON — The Missile Defense Agency awarded L3Harris Technologies a $121 million contract to build a prototype satellite capable of tracking hypersonic weapons, the agency announced Jan. 14.
Under the contract, L3Harris is tasked with building an on-orbit prototype demonstration for the agency's Hypersonic and Ballistic Tracking Space Sensor, a proliferated constellation in low Earth orbit that is capable of detecting and tracking hypersonic weapons.
The constellation is designed to fill the gap in the country's missile defense architecture created by hypersonic weapons, which are dimmer than traditional ballistic missiles, making them harder to see with the nation's infrared sensors based in geosynchronous orbit. In addition, they are able to maneuver around terrestrial sensors. With China and Russia developing these weapons, the Department of Defense is eager to develop a new constellation that can detect and track the threats anywhere in the world. And so is Congress — in December lawmakers set aside $130 million to fund the project.
The HBTSS design solves the hypersonic weapon problem by placing the sensor much closer to the Earth's surface in the lower orbit, making it easier to see the threat. But because the sensors are closer to the Earth, they have a far more limited field of view than the sensors in geosynchronous orbit. In order to achieve global coverage, the Missile Defense Agency wants a proliferated constellation made up of dozens of satellites on orbit.
L3Harris was one of four companies awarded $20 million contracts in 2019 to develop a prototype payload design and risk reduction demonstration for HBTSS, along with Northrop Grumman, Leidos and Raytheon Technologies. According to the initial contract announcements, work on those designs was due Oct. 31, 2020. With this most recent award, L3Harris has won the subsequent competition between the four companies to build the actual prototype.
The company has also been selected to build satellites for the Space Development Agency that will track hypersonic threats and feed data to HBTSS.
In October, L3Harris won a $193 million contract to build four of the agency's eight wide field of view (WFOV) satellites, with SpaceX building four more.
According to Space Development Agency leaders, their satellites will work in conjunction with HBTSS satellites to track hypersonic threats. The WFOV satellites will provide initial detection and tracing of the weapons, passing custody from satellite to satellite as the threats traverse the globe. Then, the WFOV satellites will pass custody to the medium field of view HBTSS satellites, which can provide targeting solutions with their more accurate sensors.
The WFOV satellites are scheduled for launch as early as September 2022. Work on the HBTSS prototype contract will be complete in July 2023.

Russia says its new weapon is 27 times faster than the speed of sound
By: Vladimir Isachenkov, The Associated Press MOSCOW — Russia's new strategic weapon has rendered any missile defenses useless at a small fraction of their cost, officials said Thursday. The Avangard hypersonic glide vehicle flies 27 times faster than the speed of sound, making it impossible to intercept, Deputy Prime Minister Yuri Borisov told Russian state television. The new weapon “essentially makes missile defenses useless,” he said. Borisov spoke a day after Russian President Vladimir Putin oversaw what he described as the conclusive successful test of the Avangard and hailed it as a reliable guarantee of Russia's security for decades to come. In Wednesday's test, the weapon was launched from the Dombarovskiy missile base in the southern Ural Mountains. The Kremlin said it successfully hit a practice target on the Kura shooting range on Kamchatka, 3,700 miles away. The Defense Ministry released footage from the test launch, in which a ballistic missile could be seen blasting from a silo in a cloud of smoke, but it hasn't released any images of the vehicle itself. Putin said the Avangard will enter service with the Russian Strategic Missile Forces next year. The test comes amid bitter tensions in Russia-U.S. relations, which have been strained over the Ukrainian crisis, the war in Syria and the allegations of Moscow's meddling in the 2016 U.S. presidential election. Sergei Ivanov, a former Russian defense minister, said in televised comments that the Avangard constantly changes its course and altitude as it flies through the atmosphere. He emphasized that unlike previous nuclear warheads fitted to intercontinental ballistic missiles that follow a predictable trajectory allowing it to calculate the spot where they can be intercepted, the Avangard chaotically zigzags on its path to its target, making it impossible to predict the weapon's location. A smiling Ivanov likened the weapon's flight through the atmosphere to a pebble skipping off the surface of water. Ivanov, who now serves as Putin's adviser, said the Avangard could be fitted to the Soviet-made UR-100UTTKh intercontinental ballistic missile, which is code-named SS-19 Stiletto by NATO. He noted that Russia has a stockpile of several dozen such missiles, which are in a factory-mint condition and not filled with fuel, allowing them to serve for a long time to come. Ivanov added that they could be put in existing silos, sharply reducing the costs of Avangard's deployment. "The Avangard has cost hundreds of times less than what the U.S. has spent on its missile defense," Ivanov said. He noted that Russia began to develop the Avangard after the U.S. started to develop defenses against ballistic missiles. Moscow feared that the U.S. missile shield could erode its nuclear deterrent, and Putin announced in 2004 that Russia was working on a new hypersonic weapon. Ivanov recalled that when Russian officials warned their U.S. counterparts about the new weapon program at the time, American officials were openly skeptical about Russia's ability to carry out its plan. “We aren't involved in saber-rattling, we simply ensured our security for decades to come,” he said. https://www.militarytimes.com/news/your-military/2018/12/27/russia-says-its-new-weapon-is-27-times-faster-than-the-speed-of-sound
