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.

USAF’s Future Fighter Plan May Limit Growth, Study Says
By Jen DiMascio The U.S. Air Force's plan for acquiring future fighter aircraft may crimp the service's ability to grow in the future, a study of the USAF's force structure plans indicates. The study, “The Air Force of the Future,” compares the service's force structure plans during times of peak budgets—in fiscal 2020 and fiscal 1985. In fiscal 2020, a budget of $205 billion could support 5,300 aircraft. This is a little more than half of the number that the same amount of money, adjusted for inflation, could support in 1985—9,400. The same holds true for the number of personnel, the report says. It was released Oct. 29 by Todd Harrison, director of the Aerospace Security Project at the Center for Strategic and International Studies, which examined three different studies of the size of the future force. As part of the report, Harrison drills further into the Air Force's spending habits to find that one factor underlying the inability to afford a larger force is the increase over time in operation and maintenance costs. “The average O&M cost per plane is 74% higher today in real terms than in fiscal 2001,” the report says. Looking more closely at maintenance costs, he finds that the most expensive aircraft to operate are the smallest fleets, such as the Boeing E-4 Advanced Airborne Command Post aircraft, the Northrop Grumman E-8 Joint Surveillance Target Attack Radar System and Northrop's B-2 bomber. “This is because the fixed costs of operating the fleet are distributed across more aircraft in large fleets, which brings down the overall ownership cost per plane,” the report says. “The data suggest that the Air Force could reduce operating costs by divesting aircraft that are maintained in small numbers in the current inventory and consolidating the capabilities they provide into common multimission platforms.” Air Force acquisition chief Will Roper is recommending an acquisition strategy dubbed the “digital century series.” It aims to build new fighter aircraft designed to last 3,500 flight hours in batches of hundreds, rather than the current model of pursuing advanced technology for an aircraft type that will last for decades. But Harrison estimates that the operation and sustainment cost of sustaining five different aircraft types of 72 aircraft, or 360 total aircraft, would cost about the same as sustaining 1,800 aircraft of the same type. “That's something the Air Force has got to consider,” Harrison said. “With the digital century series approach, they may end up with a bunch of small fleets and may limit the ability of the Air Force to grow in the future.” https://aviationweek.com/defense/usaf-s-future-fighter-plan-may-limit-growth-study-says
