  Trio of prototyping contracts brings new approach for collecting military weather data

  Nathan Strout WASHINGTON — The U.S. Space Force hopes its prototype low-Earth orbit weather satellites will entice commercial businesses and allied nations to partner up on the project, reducing the cost of delivering critical weather data to the war fighter. The U.S. Air Force has been trying to replace the aging Defense Meteorological Satellite Program for years, ever since Congress opted to can it in 2015. Two capabilities in particular have proven a challenge for replacement: cloud characterization and theater weather imagery. But now the Space Force thinks it has the answer. By leveraging the increasingly popular low-Earth orbit architecture demonstrated by SpaceX's Starlink constellation and other experiments, the military believes it can lower the cost of individual satellites, increase the resiliency of the systems and attract new partnerships. In a recent interview with SpaceNews, Space and Missile Systems Center Portfolio Architect Col. Russell Teehan explained the thinking behind the new approach. The Air Force previously struggled to attract partners due to the sheer cost of the systems, he said. After all, when a single satellite costs more than $700 million, it's difficult to find someone to share the load. That price point forced the Air Force to build exquisite systems, comprised of just a handful of satellites operating in higher orbits. As the Pentagon has come to understand with its other exquisite systems, in wartime this leaves the military's space-based capabilities dependent on just a few satellites that are difficult to defend. A proliferation low-Earth orbit, or P-LEO, constellation may solve both of those problems. Smaller LEO satellites can deliver the same capabilities at a fraction of the cost per satellite, while the sheer number of targets in the constellation means that the loss of a single satellite isn't crippling. “The goal is in doing that, that ideally the commercial and allied sector would increase their desire to partner on those activities,” Treehan said. “[T]he activities in the past were generally $700 million-plus individual systems, which forced us into architectures that were [made up of less than five satellites] that were significantly vulnerable if we were in a time of conflict.” The Space Force is targeting satellites in the $30-50 million range, Treehan added. The Space Force has issued a trio of prototype contracts this summer for new space-based sensors that can collect cloud characterization and theater weather imagery from low Earth orbit. Raytheon Technologies, General Atomics and Astra are leading separate prototyping efforts after receiving contracts from the Space Enterprise Consortium. The Space Force is asking for $131 million to continue these efforts in fiscal 2021. The decision to settle on LEO for this critical weather data follows years of disarray as the Pentagon has worked to find a replacement for the Defense Meteorological Satellite Program, or DMSP. For decades, the military has relied almost entirely on that program for weather data. The first satellite was launched in the 1960s, with the constellation being replenished with updated generations of weather satellites over the years. Today, there are just four DMSP satellites in operation. But no satellite is built to last forever, and there are no new DMSP satellites coming. As those satellites reach the end of their service life, they leave the two vital gaps of cloud characterization and theater weather imagery. Foreseeing this problem, Congress in 2015 directed the Air Force to launch a new weather satellite program to replace DMSP. The Air Force began working on a new constellation to launch in 2024, but there was a problem: a four-year gap between the projected end of DMSP's service life in 2020 and the launch of the new satellites. To fill that gap, the Air Force collaborated with NASA on ORS-8, a satellite to be launched just before DMSP expired. While a contract was awarded to Sierra Nevada Corp. to build that gap-filling satellite, it was protested, rescinded and ultimately canceled by the Air Force after the service determined DMSP's end-of-life date would extend beyond 2024. In 2019, the Air Force proposed a new solution: a free-flying space vehicle that would operate in low Earth orbit. The Pentagon asked for $101 million to begin the effort in fiscal 2020, with plans to launch it in 2024. But that plan didn't last the year. In September, the Air Force told Congress it wanted to scrap the free-flying space vehicle in favor of a new approach. Based on a space-based environmental monitoring capability assessment and strategy review completed in April 2019, the Air Force found it best to switch to an LEO architecture for scalability and increased resilience. Though skeptical, Congress ultimately swapped the funding for the free-flyer space vehicle to the new program. “Across the board in our weather strategies ... we're looking at multilayers of an architecture, how to most cost-effectively move forward in capability. They can be incrementally delivered over time. So that becomes a mix of large satellites that do missions and smaller satellites that we can launch in order to grow capability over time,” Col. Dennis Bythewood, program executive officer for space development at the Air Force's Space and Missile Systems Center, said in September 2019. “We're finding much more capable sensors being delivered in small packages that we think we can grow mission sets over time. Those are the types of things that we are looking at within our strategy.” https://www.c4isrnet.com/battlefield-tech/space/2020/08/17/trio-of-prototyping-contracts-brings-new-approach-for-collecting-military-weather-data/

  As deadline nears, Senate approves $674 billion defense budget bill

  By: Leo Shane III and Joe Gould WASHINGTON — With the fiscal year winding down, Senate lawmakers on Tuesday advanced a multi-agency appropriations deal that would prevent a government shutdown and give the Defense Department its full-year budget on schedule for the first time in a decade. The measure, which provides for more than $606 billion in base defense spending and nearly $68 billion more in overseas contingency funds, is in line with White House requests and spending targets outlined in the annual defense authorization bill approved earlier this summer. “After subjecting America's all-volunteer armed forces to years of belt tightening, this legislation will build on our recent progress in rebuilding the readiness of our military and investing more in the men and women who wear the uniform,” Senate Majority Leader Mitch McConnell, R-Ky., said before the Senate vote. The funding total — approved by a 93-7 vote — amounts to an increase of more than 3 percent for military spending in fiscal 2019, but as important as the boost is the timing of the measure. In recent years, Congress has struggled to pass any appropriations measures before the start of the new fiscal year, relying instead on a series of budget extensions to avoid partial government shutdowns. That has infuriated Pentagon leaders, who have said the fractured appropriations process prevents them from keeping equipment purchases and new program starts on time. If the House finalizes the appropriations measure next week and President Donald Trump signs it into law in the following week (all parties involved have already signaled they expect to do so ), it will mark the first time since 2008 that Congress and the White House have passed their spending plans on time. Senate Armed Services Committee Chairman Jim Inhofe, R-Okla., called that “a major victory” for Congress and the military. The measure funds a 2.6 percent pay raise for troops starting next January and a boost in military end strength of 16,400 spread across the active-duty and reserve forces. Operation and maintenance spending totals $243.2 billion of the defense total, and research and development efforts another $96.1 billion. Defense health and military family programs would receive $34.4 billion. The appropriations fund 13 new Navy ships ― including three DDG-51 guided missile destroyers and two Virginia-class submarines ― 93 F-35 aircraft, 58 UH-60 Black Hawk helicopters, 66 AH-64 Apache helicopters, 13 V-22 aircraft, and $1.5 billion for the upgrade of 135 Abrams tanks. The National Guard and Reserve Equipment Account would also see a $1.3 billion boost from the appropriations plan. In order to avoid political fights over non-defense spending levels, lawmakers agreed to package the military budget bill with the full-year funding for the Departments of Health and Human Services, Labor, and Education. In addition, the legislation contains a budget extension for a handful of agency budgets lawmakers have not yet finished negotiating. The move will prevent a government shutdown at the end of the month, when the fiscal year ends. Several senators lamented before the vote that all of the appropriations bills have not yet been finalized, but for the first time in years, defense advocates aren't among those complaining. In addition to the full Defense Department appropriations plan, lawmakers last week finalized a spending plan for military construction projects and the Department of Veterans Affairs, covering nearly all aspects of national defense and military personnel spending. https://www.militarytimes.com/news/2018/09/18/as-deadline-approaches-senate-advances-674-billion-defense-budget-bill
