  Can commercial satellites revolutionize nuclear command and control?

  By: Nathan Strout The rapid growth of commercial space makes the use of non-government satellites for nuclear command and control increasingly tempting, according to one official. During a speech June 26, Air Force Chief of Staff Gen. David Goldfein said that the service — which oversees both the United States' ground-based intercontinental ballistic missiles, as well as strategic bombers capable of delivering nuclear warheads — was open to the idea of using private sector satellites. “Whether it's Silicon Valley or commercial space, there's unlimited opportunities ahead right now for us in terms of how we think differently on things like nuclear command and control,” said Goldfien. “I, for one, am pretty excited about it.” The military has increasingly turned to the commercial sector to expand its capabilities more cost efficiently. For instance, the National Reconnaissance Office — the agency in charge of the nation's spy satellites — announced that it was looking to expand the amount of satellite imagery it buys from commercial companies. The Air Force has also expressed interest in developing a hybrid architecture for satellite communications, which would see war fighters able to switch between commercial and military satellites as they move through coverage areas. According to Goldfein, there's no reason that commercial capabilities could not similarly be applied to nuclear C2. “The work that we're doing in connecting the force and building a network force around the services in the conventional side has equal applications to the nuclear command and control side, because at the end of the day what we need is resilient capable architecture that keeps the commander in chief connected,” said Goldfien. “So one of the areas that I think we're going to be able to leverage significantly is the rapid and exciting expansion of commercial space in bringing low-Earth orbit capabilities that will allow us to have resilient pathways to communicate.” Currently, the military relies primarily on the Advanced Extremely High Frequency System for the nuclear sector. With four satellites in orbit and a fifth to be launched later this month, AEHF provides highly secure, anti-jamming communications for the military and national leaders like the commander in chief. It wasn't clear in Goldfein's comments whether he was interested in using commercial capabilities to augment, replace or work as a backup to AEHF and other military satellite systems. He did note that the sheer volume of satellites in some commercial constellations provides increased survivability for the network. “We want to get to a point both in conventional and unconventional, or conventional and nuclear, where if some portion of the network is taken out, our answer ought to be, ‘Peh, I've got five other pathways. And you want to take out 1,000 satellites of my constellation, of which I have five? Knock yourself out.' That's what I see is going to be a significant way that we're going to be able to leverage,” said Goldfein. The possibility of lowering costs is another major incentive to turning to the commercial sector to begin providing the communications necessary. “What we want to eventually get to is the reversal of the cost curve. Right now it actually costs us more to defend than it takes to shoot. And we want to reverse that so it actually costs them more to shoot than it takes for us to defend,” explained Goldfien. Goldfein pointed to commercial launches as an area where competition had helped drive down costs. “Increased access to affordable launch and smaller payloads that are more capable has caused this rapid expansion of commercial capabilities in space,” he said. “That may be one of the most exciting developments that we have going forward, because industry is going to help us solve many of these problems.” https://www.c4isrnet.com/battlefield-tech/c2-comms/2019/07/12/can-commercial-satellites-revolutionize-nuclear-command-and-control/

  Extending Field of View in Advanced Imaging Systems

  New program focuses on developing curved infrared focal plane arrays to improve optical performance and widen field of view while reducing system size of military imagers The military relies on advanced imaging systems for a number of critical capabilities and applications – from Intelligence, Surveillance, and Reconnaissance (ISR) and situational awareness to weapon sights. These powerful systems enable defense users to capture and analyze visual data, providing key insights both on and off the battlefield. Today, nearly all imaging systems rely on detector arrays fabricated using planar processes developed for electronic integrated circuits on flat silicon. While significant progress has been made in advancing these technologies for narrow field of view (FOV) systems, optical aberrations can limit the performance at the periphery in wide FOV systems that then require large, costly, and complex optics to correct. The trade-off for correcting optical aberrations by using large, heavy lenses is a reduction in optical signal and a large size penalty, which limits their use for new and emerging capabilities. “Tremendous progress has been made over the past 20 years towards making multi-megapixel infrared (IR) focal plane arrays (FPA) for imaging systems cost effective and available to the Department of Defense,” said Dr. Whitney Mason, a program manager in DARPA's Microsystems Technology Office (MTO). “However, limitations to the technology's performance and size remain. Current advances on the commercial side have shown the viability of small area, curved FPAs (CFPAs) for visible cameras. While these technologies have shown modest benefits, more must be done to achieve the performance and size requirements needed for imaging systems used in emerging defense applications.” DARPA developed the FOcal arrays for Curved Infrared Imagers (FOCII) program to expand upon the current commercial trend for visible sensor arrays by extending the capability to both large and medium format midwave (MWIR) and/or longwave (LWIR) infrared detectors. The program seeks to develop and demonstrate technologies for curving existing state-of-the-art large format, high performance IR FPAs to a small radius of curvature (ROC) to maximize performance, as well as curve smaller format FPAs to an extreme ROC to enable the smallest form factors possible while maintaining exquisite performance. FOCII will address this challenge through two approaches to fabricating a curved FPA. The first involves curving existing state-of-the-art FPAs, while keeping the underlying design intact. The focus of the research will be on achieving significant performance improvements over existing, flat FPAs, with a target radius of curvature of 70mm. The fundamental challenge researchers will work to address within this approach is to mitigate the mechanical strain created by curving the FPGA, particularly in silicon, which is very brittle. The second approach will focus on achieving an extreme ROC of 12.5 mm to enable a transformative reduction in the size and weight compared to current imagers. Unlike the first approach, researchers will explore possible modifications to the underlying design, including physical modifications to the silicon that could relieve or eliminate stress on the material and allow for creating the desired curvature in a smaller sized FPA. This approach will also require new methods to counter the effects of any modifications during image reconstruction in the underlying read-out integrated circuit (ROIC) algorithm. The FOCII program is hosting a proposers' day on August 13, 2019 at the Executive Conference Center, 4075 Wilson Blvd., Suite 300, Arlington, Virginia, 22203 from 9:00 a.m. to 4:00 p.m. EDT. The purpose of this meeting is to provide information on the FOCII program, promote additional discussion on this topic, address questions from potential proposers, and provide an opportunity for potential proposers to share their capabilities and ideas for teaming arrangements.
