By: Nathan Strout A recent report highlights the fact that the commercial space sector is an increasingly important part of the military's efforts in space, but there are places where industry falls short. The national security space arena is a niche market, characterized by low production runs paired with a need for high-quality products. That combination makes it a difficult area for the commercial sector. While national security space increasingly relies on industry to provide components for space vehicles, the fact remains that in some key areas there are no domestic suppliers for critical technologies, leaving the United States dependent on foreign suppliers. Here are four such technologies singled out in a recent report on the United States military's industrial base: Solar cells According to the report, the commercial sector is not investing in the research and development needed to improve solar cells, which are used to power satellites. Businesses have maxed out the capacity for triple-junction solar cells, but do not appear capable of pushing forward to four- or five-junction solar cell technology. The Pentagon also wants solar cells that are able to withstand more radiation for longer than current products on the market. Improving solar cells to get the same or more power out of even slightly smaller panels could have a major impact when it comes to launching a satellite into space, meaning that reducing solar panel size is highly valuable. Tube amplifiers Starting in the 1990s, the domestic supplier market share for traveling-wave tube amplifiers — electronic devices used to amplify radio frequency signals to high power — dropped from 50 percent to just 12 percent. While that market has shown a slight recovery, the presence of heavily subsidized companies like Thales in France make it difficult for American companies to compete. Gyroscopes Precision gyroscopes are used in spacecraft to determine altitude and are essential to providing inertial navigation systems. According to the Department of Defense, there is only one domestic supplier of hemispherical resonating gyroscopes, resulting in long lead times — the report claims that the company can only produce one to two units per month. Fiber optic gyroscopes fair better with three domestic suppliers currently manufacturing them, but those companies are themselves vulnerable to overseas supply issues with their subcomponents. Infrared detectors Just one foreign manufacturer produces the substrates necessary for space infrared detectors, and the Pentagon warns that a disruption of any more than a few months of production of the substrates could negatively impact the quality and completion of American satellites. Because of this, the U.S. government has used a Defense Production Act of 1950 provision that allows it to offer economic incentives to either develop, sustain or expand domestic production of technology critical to national defense, and an Industrial Base Analysis and Sustainment program is in the works to support the remaining two American foundries for one type of substrate. https://www.c4isrnet.com/battlefield-tech/space/2019/07/02/these-4-technologies-are-big-problems-for-us-military-space/

Posted on July 14, 2020; Boeing Press Release The U.S. Air Force awarded Boeing a nearly US$1.2 billion contract to build the first lot of eight F-15EX advanced fighter jets to help the service meet its capacity requirements and add capability to its fighter fleet. The award also covers support and one-time, upfront engineering costs. Already under construction at the Boeing F-15 production facility in St. Louis, the first two jets deliver next year. The U.S. Air Force is also announcing the overall indefinite delivery indefinite quantity contract with a ceiling value of nearly US$23 billion for F-15EX aircraft. “The F-15EX is the most advanced version of the F-15 ever built, due in large part to its digital backbone,” said Lori Schneider, Boeing F-15EX program manager. “Its unmatched range, price and best-in-class payload capacity make the F-15EX an attractive choice for the U.S. Air Force.” The F-15EX carries more weapons than any other fighter in its class, and can launch hypersonic weapons up to 22 feet long and weighing up to 7,000 pounds. To further support the digital airframe and advance rapid technology insertion, the F-15 program serves as a pathfinder for the Department of Defense's DevSecOps initiative, aimed at developing secure, flexible and agile software. Additionally, open mission systems architecture ensures its viability for decades. “F-15EX brings together benefits of digital engineering, open mission systems and agile software development to keep it affordable and upgradeable for decades to come,” said Prat Kumar, Boeing vice-president and F-15 program manager. “This means we can rapidly test and field new capabilities on F-15EX keeping our warfighters ahead of threats.” Pilots and mechanics currently operating the F-15 anticipate transitioning to the F-15EX in a matter of days as opposed to years. Future plans call for as many as 144 aircraft. “We listened to our customer every step of the way when developing this exciting jet,” said Kumar. “What we will soon deliver is a modern and robust aircraft that supports our nation's defense by incorporating the latest systems, sensors and weapons.” https://www.skiesmag.com/press-releases/boeing-and-u-s-air-force-ink-historic-deal-for-f-15ex-fighter-jet/
