    Pentagon R&D boss: The challenge of our time

    By: Mike Griffin Nov. 9 marked the 30th anniversary of the fall of the Berlin Wall, an event followed within a couple of years by the reunification of Germany, the dissolution of the Soviet Union and the freeing of the Eastern European vassal states. Francis Fukuyama thought we had reached “the end of history,” that global great power conflict was at its end and that the ascendancy of the Western liberal concept was the permanent future. “We won the Cold War” — it says so in all the history books. Winning is great, except for the part where the losers retreat, rethink, retrain and try again; while the winner thinks the race is won once and for all — which is why the United States now finds itself running from behind in certain aspects of today's great power rivalry. How did we get here, and what should we do about it? It turned out that Fukuyama was optimistic; Russia and China never accepted Western ideals as future standards. Their adherence to and promulgation of authoritarian values and behaviors was, at most, slowed by the ascendancy of the Western alliance after World War II. Russia's resurgence and China's rise offer the sobering reminder that individual freedom, property rights, free trade in open markets, transparency and accountability in government, the rule of law, and the sovereignty of nations are not universally accepted as foundational principles for human society. They are privileges to be purchased by every generation, at a high price in blood and treasure. Where possible, the United States has paid with treasure rather than with blood. This principle guided our Cold War policies. Knowing that we could not outnumber our adversaries, we invested to prevail technologically and sustained that discipline through eight presidential administrations. President Ronald Reagan won the Cold War by doubling down on the policies of the seven presidents who preceded him. Premier Mikhail Gorbachev lost because the Soviet Union could not keep up. What did we buy with those investments? First was the nuclear triad: our land-based intercontinental missiles, fleet ballistic missile submarines and strategic bombers. That force left no option for an adversary to surprise the U.S. and its allies with a decapitating first strike because the certainty of complete annihilation following such a strike was always there. Equally critical was the ability to prevail against a larger force in a conventional fight. The U.S. seized the advantage with precision, with a precise conventional strike, enabled by pattern-matching seekers. With a global positioning system to guide force projection to the right place, stealth technology to hide our aircraft from enemy radar, encrypted high-rate communications to enable superior command and control, electronic warfare to deny that advantage to our enemies, unmanned aerial vehicles for both reconnaissance and force projection, and the uncontested dominance of the space domain to tie it all together, we prevailed. These capabilities were transformational when first deployed, beyond the reach of any other society on Earth. But many are now available commercially, and others, such as electronic warfare and stealth, are now widely understood. Some potentially transformative technologies such as artificial intelligence and machine learning, 5G, and microelectronics are driven not by defense but by commercial interests, and not solely by our domestic industrial base. In certain areas with no present commercial applications, such as hypersonic flight, we are simply behind. And in space — once the uncontested linchpin of the U.S. war-fighting advantage — we are challenged by Russian and Chinese determination, and capability, to deny that advantage. In brief, the United States no longer possesses the unquestioned technical superiority to dominate a future fight. At this juncture, we have not undertaken concerted defense modernization in more than a generation, and therefore have made marginal improvements to existing capabilities. These will not affect the outcome of a conflict for which our adversaries, knowing how we fight, have been preparing for a generation. We know what we need to do. The National Defense Strategy outlines the investments we must pursue: a revitalized nuclear triad, microelectronics, cybersecurity, biotechnology, 5G, space, hypersonics, artificial intelligence, directed energy, autonomous systems, networked communications, missile defense and quantum science, among others. Superiority in these technologies, woven into a war-fighting architecture that challenges our adversaries rather than reacting to them, is the key to deterring or winning future conflicts. The taxpayers have been generous with the defense budget, but it is insufficient to purchase more legacy systems while also creating the future force. So we must decide: What near-term risks are we willing to take, and what current systems are we willing to let go, so that we can invest in capabilities that will impose costs on our adversaries and deter them from starting a fight because they know they cannot win? This is the critical national security challenge of our time. https://www.defensenews.com/outlook/2019/12/02/pentagon-rd-boss-the-challenge-of-our-time

    DARPA Prototype Reflectarray Antenna Offers High Performance in Small Package

    DARPA's Radio Frequency Risk Reduction Deployment Demonstration (R3D2) is set for launch in late February to space-qualify a new type of membrane reflectarray antenna. The antenna, made of a tissue-thin Kapton membrane, packs tightly for stowage during launch and then will deploy to its full size of 2.25 meters in diameter once it reaches low Earth orbit. R3D2 will monitor antenna deployment dynamics, survivability and radio frequency (RF) characteristics of a membrane antenna in low-Earth orbit. The antenna could enable multiple missions that currently require large satellites, to include high data rate communications to disadvantaged users on the ground. A successful demonstration also will help prove out a smaller, faster-to-launch and lower cost capability, allowing the Department of Defense, as well as other users, to make the most of the new commercial market for small, inexpensive launch vehicles. Satellite design, development, and launch took approximately 18 months. “The Department of Defense has prioritized rapid acquisition of small satellite and launch capabilities. By relying on commercial acquisition practices, DARPA streamlined the R3D2 mission from conception through launch services acquisition,” said Fred Kennedy, director of DARPA's Tactical Technology Office. “This mission could help validate emerging concepts for a resilient sensor and data transport layer in low Earth orbit – a capability that does not exist today, but one which could revolutionize global communications by laying the groundwork for a space-based internet.” The launch will take place on a Rocket Lab USA Electron rocket from the company's launch complex on the Mahia Peninsula of New Zealand. Northrop Grumman is the prime contractor and integrated the 150 kg satellite; MMA Design designed and built the antenna. Trident Systems designed and built R3D2's software-defined radio, while Blue Canyon Technologies provided the spacecraft bus. Rocket Lab will host a webcast and provide coverage of the launch via live stream: http://www.rocketlabusa.com/live-stream. https://www.darpa.mil/news-events/2019-01-22b

    Exclusive: Qatar makes formal request for F-35 jets - sources

    Mike Stone WASHINGTON (Reuters) - Qatar has submitted a formal request to the United States to buy stealthy F-35 fighter jets, three people familiar with the deal said, in a deal that if pursued could strain U.S. ties with Saudi Arabia and Israel. The request for the Lockheed Martin Co jets was submitted by the Persian Gulf state in recent weeks, the people said. A U.S. State Department spokesman said, “As a matter of policy, the United States does not confirm or comment on proposed defense sales or transfers until they are formally notified to Congress.” The Qatari embassy in Washington, D.C. did not immediately respond to a request for comment. Keen to counter Iran in the region, the U.S. helps to arm allies including Qatar, host to the largest U.S. military facility in the Middle East, and home to 8,000 U.S. service members and Department of Defense civilian employees. The request follows an August deal between the U.S. and the United Arab Emirates in which Washington agreed to consider giving the Gulf state approval to buy F-35s in a side deal to a U.S.-brokered agreement called the Abraham Accord to normalize diplomatic ties with Israel. Israel has signaled stiff opposition to a UAE sale and would likely be just as resistant to one with Qatar, fearing it could undercut its military advantage in the Middle East. In Washington, a fourth person familiar with the matter said concern about Qatar's links to Hamas have frequently surfaced over arms sales to the Gulf state. But in the case of an advanced warplane like the F-35, it could be a deal breaker. One of the people said Qatar's letter of request for the jets, the first formal step in the legal process of foreign military sale, was not directly linked to its adoption of the Abraham Accord. Nor has Qatar shown any sign it will normalize ties with Israel. U.S. and Qatar have close ties. In September Secretary of State Mike Pompeo and Qatar Foreign Minister Sheikh Mohammed bin Abdulrahman al-Thani met in Washington as the U.S. hopes to move forward with naming Qatar as a major non-NATO ally. Despite being U.S. allies, both the potential Qatari and UAE F-35 deals must satisfy a decades-old agreement with Israel that states any U.S. weapons sold to the region must not impair Israel's “qualitative military edge,” guaranteeing U.S. weapons furnished to Israel are “superior in capability” to those sold to its neighbors. Saudi Arabia, Washington's most powerful and closest partner among the Gulf Arab states, is also likely to oppose the United States supplying F-35s to Qatar. Saudi Arabia, the United Arab Emirates, Bahrain and Egypt remain locked in a three-year standoff with Qatar that the Trump administration has tried to end, so far without success. A formal letter of request typically contains specifications that would be used to furnish pricing data to a customer, but currently the F-35A, a fifth generation stealthy fighter jet, costs around $80 million. Any F-35 sale could take years to negotiate and deliver, giving a new U.S. presidential administration ample time to halt the deals. Any sale would also need congressional approval. Poland, the most recent F-35 customer, purchased 32 of the jets, but will not receive its first delivery until 2024.
