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.”

Nathan Strout WASHINGTON — Could drones hold the answer to putting satellites on orbit faster? Space logistics company Aevum is betting on it with its new Ravn X drone, which it built in the hopes of launching rockets into orbit every three hours. “Aevum is completely reimagining access to space,” said Jay Skylus, Aevum's founder and chief executive, said in a statement unveiling the new launch solution Dec. 3. “U.S. leadership has identified the critical need for extremely fast access to low Earth orbit. We're faster than anybody. “Through our autonomous technologies, Aevum will shorten the lead time of launches from years to months, and when our customers demand it, minutes,” he added. Founded in 2016, the company has been developing its product in stealth mode for years. On Dec. 3, they officially unveiled the new Ravn X autonomous launch solution ― an 80-foot long drone designed to launch small payloads into low Earth orbit. The company has yet to conduct its first test flight but is working toward airworthiness certification. Leaders hope to launch a payload for the military before the end of 2021. “We have a small launch vehicle that's more or less designed from scratch to be reusable and for responsive space access,” Skylus told C4ISRNET in an interview. “We do this by operating this sort of three stage launch vehicle stack. The first stage is an unmanned aircraft that is completely autonomous. The second and third stages are rocket systems.” Following take off, the drone rises to between 30,000 and 60,000 feet, where the rocket separates and ignites, launching the payload into orbit. Ravn X can take off and land horizontally on any airstrip at least one mile long. “The entire system is designed for a turnaround time and response time of about 180 minutes,” Skylus explained. The idea of launching satellites into space from the air isn't a new concept. For example, Northrop Grumman's Pegasus rocket ― designed to be launched into orbit from a carrier aircraft ― has been used for Defense Advanced Research Projects Agency, Air Force and NASA missions since the 1990s, with the most recent mission taking place in October 2019. A more recent entrant into the air-launch-to-orbit arena is Virgin Orbit's LauncherOne rocket. The company's first test flight, which failed to reach orbit, was conducted in May 2020. Aevum thinks of itself as taking the concept one step further by adding autonomy to the launch process. “This entire process is more or less fully autonomous, and this allows us to basically reduce the cost of labor that's required by about 90 percent,” said Skylus. Aevum's approach also gets at one of the most frustrating issues with launch: weather. In 2018, the Defense Advanced Research Projects Agency announced the DARPA Launch Challenge, where small launch companies were asked to show that they could put a payload into space within just 30 days. While about 50 companies applied, by 2019 their were only three companies remaining in the competition. By 2020, there was just one: Astra Space. The company came close to achieving its goal, ultimately failing after inclement weather forced them to scrub multiple launch attempts. Ravn X is largely impervious to those issues. “Because of the architecture, we're really not dependent on weather and those types of things. We expect to be available more than 96 percent of the year,” said Skylus. The company is already drawing attention from the Department of Defense. Ravn X's first mission will be the ASLON-45 mission for the U.S. Space Force, a $5 million contract. With that mission, the focus is on showing how the company can get a payload into orbit in 24 hours or less, said Skylus. That launch is expected to be complete before the end of 2021. In addition, the company has received a Phase II Small Business Innovation Research award, a classified contract, and is one of eight company's to receive a $986 million indefinite delivery, indefinite quantity contract for Orbital Services Program-4. “I'm excited to see the bold innovation and responsiveness in development today by our small launch industry partners to support emerging war fighter needs” said Lt. Col. Ryan Rose, Chief of the Space and Missile Systems Center's Small Launch and Targets Division, in a statement coordinated with Aevum's announcement. “The U.S. Space Force is proactively partnering with industry to support U.S. space superiority objectives. Having a robust U.S. industry providing responsive launch capability is key to ensuring the U.S. Space Force can respond to future threats.” The Pentagon has been pushing industry for responsive launch solutions, ensuring that they can place payloads into orbit with little notice. Aevum's focus on software and automation gives them an edge in meeting those elusive responsive launch requirements, Skylus said. “The responsive space launch type of problem has been a problem for several decades now, and the government has been seeking a solution to this. While others, our peers, are trying to tackle this from a technology/engineering perspective, Aevum is really tackling the problem from a system level perspective,” said Skylus. That's meant taking proven hardware solutions and applying autonomous software solutions to the ground processes and mission assurance elements. “If you look at our financials and things like that, we really do look more like a software company as opposed to a launch company,” said Skylus. “Which is great, because that means we're profitable right out of the gate.” For Aevum, the focus is on being that dependable, responsive launch service, and that may come at a premium for prospective customers, including the Pentagon. “We're not looking to be the lowest cost provider. That was never something that we claimed to be,” said Skylus. “Our focus has been: How do we make sure that we can go when our customers need to go? “Our niche market is going to be composed of customers like the Department of Defense who can't afford to wait a week to gather intel ... Or a customer like a commercial constellation customer who if they're down for over a week, they're going to lose more in revenue than they would be willing to pay for a launch,” he continued. “Those are the customers that we're really targeting.” https://www.c4isrnet.com/battlefield-tech/space/2020/12/03/this-company-wants-to-launch-satellites-into-space-via-drone/

BY C. TODD LOPEZ In the context of U.S. defense policy, "deterrence" is typically understood to mean "nuclear." And America's nuclear triad — ground-based missiles, air-delivered bombs, and submarine-launched missiles — serves as America's biggest form of deterrence, which underwrites everything its men and women in uniform do. But according to Chief of Naval Operations Adm. John M. Richardson, nuclear weapons are just one of multiple elements of deterrence the U.S. must consider either for itself, or for being aware that other nations might be using them. During a July 2 breakfast presentation hosted by the Mitchell Institute for Aerospace Studies in Washington, Richardson laid out five such elements of deterrence already in use or that must be considered more deeply. Nuclear "It's an incredibly powerful military capability where potentially everybody gets destroyed," Richardson said. "We must maintain our ability to be competitive and relevant in this domain ... [and] strike back at anybody who can pose an existential nuclear threat to the homeland." The triad itself includes ground-based missiles — commonly referred to as intercontinental ballistic missiles; submarine-launched ballistic missiles; and air-launched cruise missiles dropped from bomber aircraft. In all three areas the U.S. is underway with modernization efforts. But the nuclear environment globally is changing, Richardson said. "More nations are seeking to join the club," he said. Some of those nations can bring high-tech weapons, while some are using low-tech, including dirty bombs and systems that can be manufactured with 3-D printers. Additionally, not all nuclear weapons are "strategic" in nature. Some are smaller "tactical" weapons. "The nuclear element of this mix remains very relevant, very active, and deserves a lot more attention in my mind," Richardson said. Cyber Richardson said when it comes to cyber as a deterrent, the U.S. can't maintain only defensive capabilities. "We have to have an ability for offensive cyber to truly achieve a sense of deterrence there," he said. Recent cyber provocations, he said, are "multidimensional in ways that may or may not have been expected." Included there, he said, are theft of intellectual property, invasion of privacy, invasion of identity, distortion of identity, "and most recently, perception management. This perception management idea ... might be kind of our new Sputnik moment." Space "The competition is absolutely heating up in space," Richardson said. "Of these elements that are going to constitute a tailored strategic deterrent approach, space has got to be one of those." Richard posited that in space, it might become apparent that, using directed energy weapons, it proves far easier to destroy something in space than it is to put something back up into space. "These things operate really fast ... and space goes away as an asset," he said. "You can see kind of a mutually assured destruction scenario in space pretty easily. Have we thought about that going forward?" Chemical, Biological Capabilities Increasingly, Richardson said, chemical and biological deterrence will come into the mix, especially as technologies such as CRISPR — a genome editing tool — allow for more tailored capabilities. "One of the self-deterrent aspects of chemical/biological is that it's very hard to control. It goes viral, if you will," he said. "But with these tailoring things, you can get a lot more specific. It becomes a lot more targetable. And so, it's something we have to mind." Conventional Weapons U.S. deterrence advantages in conventional weapons have relied, so far, on superior targeting ability, Richardson said. But that may become less important. "We have better sensors, better satellites, better ways to connect that data with our command and control systems, our targeting systems," he said. "We had an advantage in terms of precision." Now, he said, such sensors are ubiquitous, and commercial and military sensors are going up into space. There are cameras everywhere. "This idea of being able to locate things with precision is becoming more ubiquitous," he said. "It's less of an advantage. It's really the team that can manage that information better that's going to achieve the advantage." https://www.defense.gov/explore/story/Article/1896147/us-security-requires-multiple-elements-of-deterrence/
