  L3Harris to build prototype satellite capable of tracking hypersonic weapons

  Nathan Strout 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. https://www.c4isrnet.com/battlefield-tech/space/2021/01/14/l3harris-to-build-prototype-satellite-capable-of-tracking-hypersonic-weapons/

  Kuwait wants to spend over $1.4 billion on Patriot upgrades

  By: Aaron Mehta WASHINGTON — The U.S. State Department has OK'd a trio of packages to update Kuwait's Patriot missile defense systems, with a combined potential price tag of $1.425 billion. The three packages, announced on the website of the U.S. Defense Security Cooperation Agency on Thursday, include $425 million for sustainment and technical assistance, $200 million for a repair and return program, and $800 million for 84 Patriot Advanced Capability (PAC-3) missile segment enhancements. DSCA notifications are not final sales; if cleared by Congress, Kuwait will then enter negotiations over the package, during which quantities and costs can shift. The potential sales “will supplement and improve Kuwait's capability to meet current and future threats and provide greater security for its critical oil and natural gas infrastructure,” according to the DSCA. “Kuwait will use the enhanced capability to strengthen its homeland defense. Kuwait will have no difficulty absorbing this equipment and services into its armed forces.” The repair and return program involves shipping items that can't be serviced on the ground back to the U.S. military for refurbishment, and then inducted into the military's regular repair cycle. When the repairs are complete, the parts are shipped back to the country that owns them, which is then billed for the repairs. Work will be performed at a number of locations, primarily the Huntsville, Alabama, locations of Raytheon, Lockheed Martin, Leido and KBR. In addition, work on the PAC-3 missile segments will be done at Lockheed's Dallas, Texas, office. Kuwait has been a reliable customer for American military goods. Excluding Thursday's announcements, the country has been cleared for 13 Foreign Military Sales cases since the start of fiscal 2017, with an estimated price tag of $13.9 billion. https://www.defensenews.com/global/mideast-africa/2020/05/28/kuwait-wants-to-spend-over-14-billion-on-patriot-upgrades/
